Detailed Description

Manages the organisation and rendering of a 'scene' i.e.

a collection of objects and potentially world geometry.

Remarks

This class defines the interface and the basic behaviour of a 'Scene Manager'. A SceneManager organises the culling and rendering of the scene, in conjunction with the RenderQueue. This class is designed to be extended through subclassing in order to provide more specialised scene organisation structures for particular needs. The default SceneManager culls based on a hierarchy of node bounding boxes, other implementations can use an octree (

See also

OctreeSceneManager), a BSP tree (

BspSceneManager), and many other options. New SceneManager implementations can be added at runtime by plugins, see SceneManagerEnumerator for the interfaces for adding new SceneManager types.

There is a distinction between 'objects' (which subclass MovableObject, and are movable, discrete objects in the world), and 'world geometry', which is large, generally static geometry. World geometry tends to influence the SceneManager organisational structure (e.g. lots of indoor static geometry might result in a spatial tree structure) and as such world geometry is generally tied to a given SceneManager implementation, whilst MovableObject instances can be used with any SceneManager. Subclasses are free to define world geometry however they please.

Multiple SceneManager instances can exist at one time, each one with a distinct scene. Which SceneManager is used to render a scene is dependent on the Camera, which will always call back the SceneManager which created it to render the scene.

Member Function Documentation

prepareShadowTextures()

virtual void Ogre::SceneManager::prepareShadowTextures ( Camera *  cam, Viewport *  vp, const LightList *  lightList = 0  )

virtual

Method for preparing shadow textures ready for use in a regular render Do not call manually unless before frame start or rendering is paused If lightList is not supplied, will render all lights in frustum.

Reimplemented in Ogre::PCZSceneManager.

_pauseRendering()

RenderContext* Ogre::SceneManager::_pauseRendering

(

)

Pause rendering of the frame.

This has to be called when inside a renderScene call (Usually using a listener of some sort)

_resumeRendering()

void Ogre::SceneManager::_resumeRendering

(

RenderContext *

context

)

Resume rendering of the frame.

This has to be called after a _pauseRendering call

Parameters

context

The rendring context, as returned by the _pauseRendering call

OGRE_MUTEX()

Ogre::SceneManager::OGRE_MUTEX

(

sceneGraphMutex

)

Mutex to protect the scene graph from simultaneous access from multiple threads.

Remarks

If you are updating the scene in a separate thread from the rendering thread, then you should lock this mutex before making any changes to the scene graph - that means creating, modifying or deleting a scene node, or attaching / detaching objects. It is your responsibility to take out this lock, the detail methods on the nodes will not do it for you (for the reasons discussed below).

Note that locking this mutex will prevent the scene being rendered until it is unlocked again. Therefore you should do this sparingly. Try to create any objects you need separately and fully prepare them before doing all your scene graph work in one go, thus keeping this lock for the shortest time possible.

Note

A single global lock is used rather than a per-node lock since it keeps the number of locks required during rendering down to a minimum. Obtaining a lock, even if there is no contention, is not free so for performance it is good to do it as little as possible. Since modifying the scene in a separate thread is a fairly rare occurrence (relative to rendering), it is better to keep the locking required during rendering lower than to make update locks more granular.

getName()

const String& Ogre::SceneManager::getName ( void  ) const

inline

Return the instance name of this SceneManager.

getTypeName()

virtual const String& Ogre::SceneManager::getTypeName ( void  ) const

pure virtual

Retrieve the type name of this scene manager.

Remarks

This method has to be implemented by subclasses. It should return the type name of this SceneManager which agrees with the type name of the SceneManagerFactory which created it.

Implemented in Ogre::BspSceneManager, Ogre::OctreeSceneManager, Ogre::PCZSceneManager, and Ogre::DefaultSceneManager.

createCamera()

virtual Camera* Ogre::SceneManager::createCamera ( const String &  name )

virtual

Creates a camera to be managed by this scene manager.

Remarks

This camera must be added to the scene at a later time using the attachObject method of the SceneNode class.

Parameters

name	Name to give the new camera.

Reimplemented in Ogre::PCZSceneManager, and Ogre::OctreeSceneManager.

getCamera()

Camera* Ogre::SceneManager::getCamera

(

const String &

name

)

const

Retrieves a pointer to the named camera.

Note

Throws an exception if the named instance does not exist

hasCamera()

bool Ogre::SceneManager::hasCamera

(

const String &

name

)

const

Returns whether a camera with the given name exists.

destroyCamera() [1/2]

virtual void Ogre::SceneManager::destroyCamera ( Camera *  cam )

virtual

Removes a camera from the scene.

Remarks

This method removes a previously added camera from the scene. The camera is deleted so the caller must ensure no references to it's previous instance (e.g. in a SceneNode) are used.

Parameters

cam	Pointer to the camera to remove

destroyCamera() [2/2]

virtual void Ogre::SceneManager::destroyCamera ( const String &  name )

virtual

Removes a camera from the scene.

Remarks

This method removes an camera from the scene based on the camera's name rather than a pointer.

destroyAllCameras()

virtual void Ogre::SceneManager::destroyAllCameras ( void  )

virtual

Removes (and destroys) all cameras from the scene.

Remarks

Some cameras are internal created to dealing with texture shadow, their aren't supposed to destroy outside. So, while you are using texture shadow, don't call this method, or you can set the shadow technique other than texture-based, which will destroy all internal created shadow cameras and textures.

createLight() [1/2]

virtual Light* Ogre::SceneManager::createLight ( const String &  name )

virtual

Creates a light for use in the scene.

Remarks

Lights can either be in a fixed position and independent of the scene graph, or they can be attached to SceneNodes so they derive their position from the parent node. Either way, they are created using this method so that the SceneManager manages their existence.

Parameters

name	The name of the new light, to identify it later.

Reimplemented in Ogre::PCZSceneManager.

createLight() [2/2]

virtual Light* Ogre::SceneManager::createLight ( )

virtual

Creates a light with a generated name.

getLight()

virtual Light* Ogre::SceneManager::getLight ( const String &  name ) const

virtual

Returns a pointer to the named Light which has previously been added to the scene.

Note

Throws an exception if the named instance does not exist

Reimplemented in Ogre::PCZSceneManager.

hasLight()

virtual bool Ogre::SceneManager::hasLight ( const String &  name ) const

virtual

Returns whether a light with the given name exists.

Reimplemented in Ogre::PCZSceneManager.

getLightClippingPlanes()

const PlaneList& Ogre::SceneManager::getLightClippingPlanes

(

Light *

l

)

Retrieve a set of clipping planes for a given light.

getLightScissorRect()

const RealRect& Ogre::SceneManager::getLightScissorRect	(	Light *	l,
		const Camera *	cam
	)

Retrieve a scissor rectangle for a given light and camera.

invalidatePerFrameScissorRectCache()

virtual void Ogre::SceneManager::invalidatePerFrameScissorRectCache ( )

virtual

Scissor rects are cached during frame, and this cache should be explicitly invalidated if several renders are done during one frame using different projections matrices, for example for tiled, stereo or multiview orthographic projection rendering.

destroyLight() [1/2]

virtual void Ogre::SceneManager::destroyLight ( const String &  name )

virtual

Removes the named light from the scene and destroys it.

Remarks

Any pointers held to this light after calling this method will be invalid.

Reimplemented in Ogre::PCZSceneManager.

destroyLight() [2/2]

virtual void Ogre::SceneManager::destroyLight ( Light *  light )

virtual

Removes the light from the scene and destroys it based on a pointer.

Remarks

Any pointers held to this light after calling this method will be invalid.

destroyAllLights()

virtual void Ogre::SceneManager::destroyAllLights ( void  )

virtual

Removes and destroys all lights in the scene.

Reimplemented in Ogre::PCZSceneManager.

_notifyLightsDirty()

void Ogre::SceneManager::_notifyLightsDirty

(

void

)

Advance method to increase the lights dirty counter due lights changed.

Remarks

Scene manager tracking lights that affecting the frustum, if changes detected (the changes includes light list itself and the light's position and attenuation range), then increase the lights dirty counter.

For some reason, you can call this method to force whole scene objects re-populate their light list. But near in mind, call to this method will harm performance, so should avoid if possible.

_getLightsDirtyCounter()

ulong Ogre::SceneManager::_getLightsDirtyCounter ( void  ) const

inline

Advance method to gets the lights dirty counter.

Remarks

Scene manager tracking lights that affecting the frustum, if changes detected (the changes includes light list itself and the light's position and attenuation range), then increase the lights dirty counter.

When implementing customise lights finding algorithm relied on either SceneManager::_getLightsAffectingFrustum or SceneManager::_populateLightList, might check this value for sure that the light list are really need to re-populate, otherwise, returns cached light list (if exists) for better performance.

References Ogre::ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME, and Ogre::ViewPoint::position.

_getLightsAffectingFrustum()

const LightList& Ogre::SceneManager::_getLightsAffectingFrustum

(

void

)

const

Get the list of lights which could be affecting the frustum.

Remarks

Note that default implementation of this method returns a cached light list, which is populated when rendering the scene. So by default the list of lights is only available during scene rendering.

_populateLightList() [1/2]

void Ogre::SceneManager::_populateLightList	(	const Vector3 &	position,
		Real	radius,
		LightList &	destList,
		uint32	lightMask = 0xFFFFFFFF
	)

Populate a light list with an ordered set of the lights which are closest to the position specified.

Remarks

Note that since directional lights have no position, they are always considered closer than any point lights and as such will always take precedence.

Subclasses of the default SceneManager may wish to take into account other issues such as possible visibility of the light if that information is included in their data structures. This basic scenemanager simply orders by distance, eliminating those lights which are out of range or could not be affecting the frustum (i.e. only the lights returned by SceneManager::_getLightsAffectingFrustum are take into account).

The number of items in the list max exceed the maximum number of lights supported by the renderer, but the extraneous ones will never be used. In fact the limit will be imposed by Pass::getMaxSimultaneousLights.

Parameters

position	The position at which to evaluate the list of lights
radius	The bounding radius to test
destList	List to be populated with ordered set of lights; will be cleared by this method before population.
lightMask	The mask with which to include / exclude lights

_populateLightList() [2/2]

void Ogre::SceneManager::_populateLightList	(	const SceneNode *	sn,
		Real	radius,
		LightList &	destList,
		uint32	lightMask = 0xFFFFFFFF
	)

Populates a light list with an ordered set of the lights which are closest to the position of the SceneNode given.

Remarks

Note that since directional lights have no position, they are always considered closer than any point lights and as such will always take precedence. This overloaded version will take the SceneNode's position and use the second method to populate the list.

Subclasses of the default SceneManager may wish to take into account other issues such as possible visibility of the light if that information is included in their data structures. This basic scenemanager simply orders by distance, eliminating those lights which are out of range or could not be affecting the frustum (i.e. only the lights returned by SceneManager::_getLightsAffectingFrustum are take into account).

Also note that subclasses of the SceneNode might be used here to provide cached scene related data, accelerating the list population (for example light lists for SceneNodes could be cached inside subclassed SceneNode objects).

The number of items in the list may exceed the maximum number of lights supported by the renderer, but the extraneous ones will never be used. In fact the limit will be imposed by Pass::getMaxSimultaneousLights.

Parameters

sn	The SceneNode for which to evaluate the list of lights
radius	The bounding radius to test
destList	List to be populated with ordered set of lights; will be cleared by this method before population.
lightMask	The mask with which to include / exclude lights

createSceneNode() [1/2]

virtual SceneNode* Ogre::SceneManager::createSceneNode ( void  )

virtual

Creates an instance of a SceneNode.

Remarks

Note that this does not add the SceneNode to the scene hierarchy. This method is for convenience, since it allows an instance to be created for which the SceneManager is responsible for allocating and releasing memory, which is convenient in complex scenes.

To include the returned SceneNode in the scene, use the addChild method of the SceneNode which is to be it's parent.

Note that this method takes no parameters, and the node created is unnamed (it is actually given a generated name, which you can retrieve if you want). If you wish to create a node with a specific name, call the alternative method which takes a name parameter.

Reimplemented in Ogre::PCZSceneManager.

createSceneNode() [2/2]

virtual SceneNode* Ogre::SceneManager::createSceneNode ( const String &  name )

virtual

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Reimplemented in Ogre::PCZSceneManager.

destroySceneNode() [1/2]

virtual void Ogre::SceneManager::destroySceneNode ( SceneNode *  sn )

virtual

Destroys a SceneNode.

Remarks

This allows you to physically delete an individual SceneNode if you want to. Note that this is not normally recommended, it's better to allow SceneManager to delete the nodes when the scene is cleared.

Reimplemented in Ogre::PCZSceneManager.

destroySceneNode() [2/2]

virtual void Ogre::SceneManager::destroySceneNode ( const String &  name )

virtual

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Reimplemented in Ogre::PCZSceneManager, and Ogre::OctreeSceneManager.

getRootSceneNode()

SceneNode* Ogre::SceneManager::getRootSceneNode

(

void

)

Gets the SceneNode at the root of the scene hierarchy.

Remarks

The entire scene is held as a hierarchy of nodes, which allows things like relative transforms, general changes in rendering state etc (See the SceneNode class for more info). In this basic SceneManager class, the application using Ogre is free to structure this hierarchy however it likes, since it has no real significance apart from making transforms relative to each node (more specialised subclasses will provide utility methods for building specific node structures e.g. loading a BSP tree).

However, in all cases there is only ever one root node of the hierarchy, and this method returns a pointer to it.

getSceneNode()

SceneNode* Ogre::SceneManager::getSceneNode

(

const String &

name

)

const

Retrieves a named SceneNode from the scene graph.

Remarks

If you chose to name a SceneNode as you created it, or if you happened to make a note of the generated name, you can look it up wherever it is in the scene graph using this method.

Note

Throws an exception if the named instance does not exist

hasSceneNode()

bool Ogre::SceneManager::hasSceneNode

(

const String &

name

)

const

Returns whether a scene node with the given name exists.

createParticleSystem() [1/3]

ParticleSystem* Ogre::SceneManager::createParticleSystem	(	const String &	name,
		const String &	templateName
	)

Creates a particle system based on a template.

Remarks

This method creates a new ParticleSystem instance based on the named template (defined through ParticleSystemManager::createTemplate) and returns a pointer to the caller. The caller should not delete this object, it will be freed at system shutdown, or can be released earlier using the destroyParticleSystem method.

Each system created from a template takes the template's settings at the time of creation, but is completely separate from the template from there on.

Creating a particle system does not make it a part of the scene. As with other MovableObject subclasses, a ParticleSystem is not rendered until it is attached to a SceneNode.

This is probably the more useful particle system creation method since it does not require manual setup of the system. Note that the initial quota is based on the template but may be changed later.

Parameters

name	The name to give the new particle system instance.
templateName	The name of the template to base the new instance on.

createParticleSystem() [2/3]

ParticleSystem* Ogre::SceneManager::createParticleSystem	(	const String &	name,
		size_t	quota = 500,
		const String &	resourceGroup = ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME
	)

Create a blank particle system.

Remarks

This method creates a new, blank ParticleSystem instance and returns a pointer to it. The caller should not delete this object, it will be freed at system shutdown, or can be released earlier using the destroyParticleSystem method.

The instance returned from this method won't actually do anything because on creation a particle system has no emitters. The caller should manipulate the instance through it's ParticleSystem methods to actually create a real particle effect.

Creating a particle system does not make it a part of the scene. As with other MovableObject subclasses, a ParticleSystem is not rendered until it is attached to a SceneNode.

Parameters

name	The name to give the ParticleSystem.
quota	The maximum number of particles to allow in this system.
resourceGroup	The resource group which will be used to load dependent resources

createParticleSystem() [3/3]

ParticleSystem* Ogre::SceneManager::createParticleSystem	(	size_t	quota = 500,
		const String &	resourceGroup = ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME
	)

Create a blank particle system with a generated name.

Remarks

This method creates a new, blank ParticleSystem instance and returns a pointer to it. The caller should not delete this object, it will be freed at system shutdown, or can be released earlier using the destroyParticleSystem method.

The instance returned from this method won't actually do anything because on creation a particle system has no emitters. The caller should manipulate the instance through it's ParticleSystem methods to actually create a real particle effect.

clearScene()

virtual void Ogre::SceneManager::clearScene ( void  )

virtual

Empties the entire scene, inluding all SceneNodes, Entities, Lights, BillboardSets etc.

Cameras are not deleted at this stage since they are still referenced by viewports, which are not destroyed during this process.

Reimplemented in Ogre::OctreeSceneManager, and Ogre::PCZSceneManager.

setAmbientLight()

void Ogre::SceneManager::setAmbientLight

(

const ColourValue &

colour

)

Sets the ambient light level to be used for the scene.

Remarks

This sets the colour and intensity of the ambient light in the scene, i.e. the light which is 'sourceless' and illuminates all objects equally. The colour of an object is affected by a combination of the light in the scene, and the amount of light that object reflects (in this case based on the Material::ambient property).

By default the ambient light in the scene is ColourValue::Black, i.e. no ambient light. This means that any objects rendered with a Material which has lighting enabled (see Material::setLightingEnabled) will not be visible unless you have some dynamic lights in your scene.

getAmbientLight()

const ColourValue& Ogre::SceneManager::getAmbientLight

(

void

)

const

Returns the ambient light level to be used for the scene.

prepareWorldGeometry() [1/2]

virtual void Ogre::SceneManager::prepareWorldGeometry ( const String &  filename )

virtual

Sets the source of the 'world' geometry, i.e.

the large, mainly static geometry making up the world e.g. rooms, landscape etc. This function can be called before setWorldGeometry in a background thread, do to some slow tasks (e.g. IO) that do not involve the backend render system.

Remarks

Depending on the type of SceneManager (subclasses will be specialised for particular world geometry types) you have requested via the Root or SceneManagerEnumerator classes, you can pass a filename to this method and it will attempt to load the world-level geometry for use. If you try to load an inappropriate type of world data an exception will be thrown. The default SceneManager cannot handle any sort of world geometry and so will always throw an exception. However subclasses like BspSceneManager can load particular types of world geometry e.g. "q3dm1.bsp".

prepareWorldGeometry() [2/2]

virtual void Ogre::SceneManager::prepareWorldGeometry ( DataStreamPtr &  stream, const String &  typeName = BLANKSTRING  )

virtual

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters

stream	Data stream containing data to load
typeName	String identifying the type of world geometry contained in the stream - not required if this manager only supports one type of world geometry.

setWorldGeometry() [1/2]

virtual void Ogre::SceneManager::setWorldGeometry ( const String &  filename )

virtual

Sets the source of the 'world' geometry, i.e.

the large, mainly static geometry making up the world e.g. rooms, landscape etc.

Remarks

Depending on the type of SceneManager (subclasses will be specialised for particular world geometry types) you have requested via the Root or SceneManagerEnumerator classes, you can pass a filename to this method and it will attempt to load the world-level geometry for use. If you try to load an inappropriate type of world data an exception will be thrown. The default SceneManager cannot handle any sort of world geometry and so will always throw an exception.

setWorldGeometry() [2/2]

virtual void Ogre::SceneManager::setWorldGeometry ( DataStreamPtr &  stream, const String &  typeName = BLANKSTRING  )

virtual

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters

stream	Data stream containing data to load
typeName	String identifying the type of world geometry contained in the stream - not required if this manager only supports one type of world geometry.

Reimplemented in Ogre::BspSceneManager.

estimateWorldGeometry() [1/2]

virtual size_t Ogre::SceneManager::estimateWorldGeometry ( const String &  filename )

inlinevirtual

Estimate the number of loading stages required to load the named world geometry.

Remarks

This method should be overridden by SceneManagers that provide custom world geometry that can take some time to load. They should return from this method a count of the number of stages of progress they can report on whilst loading. During real loading (setWorldGeometry), they should call ResourceGroupManager::_notifyWorldGeometryProgress exactly that number of times when loading the geometry for real.

Note

The default is to return 0, ie to not report progress.

Reimplemented in Ogre::BspSceneManager.

estimateWorldGeometry() [2/2]

virtual size_t Ogre::SceneManager::estimateWorldGeometry ( DataStreamPtr &  stream, const String &  typeName = BLANKSTRING  )

inlinevirtual

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters

stream	Data stream containing data to load
typeName	String identifying the type of world geometry contained in the stream - not required if this manager only supports one type of world geometry.

Reimplemented in Ogre::BspSceneManager.

getSuggestedViewpoint()

virtual ViewPoint Ogre::SceneManager::getSuggestedViewpoint ( bool  random = false )

virtual

Asks the SceneManager to provide a suggested viewpoint from which the scene should be viewed.

Remarks

Typically this method returns the origin unless a) world geometry has been loaded using SceneManager::setWorldGeometry and b) that world geometry has suggested 'start' points. If there is more than one viewpoint which the scene manager can suggest, it will always suggest the first one unless the random parameter is true.

Parameters

random

If true, and there is more than one possible suggestion, a random one will be used. If false the same one will always be suggested.

Returns

On success, true is returned.

On failure, false is returned.

Reimplemented in Ogre::BspSceneManager.

setOption()

virtual bool Ogre::SceneManager::setOption ( const String &  strKey, const void *  pValue  )

inlinevirtual

Method for setting a specific option of the Scene Manager.

These options are usually specific for a certain implemntation of the Scene Manager class, and may (and probably will) not exist across different implementations.

Parameters

strKey	The name of the option to set
pValue	A pointer to the value - the size should be calculated by the scene manager based on the key

Returns

On success, true is returned.

On failure, false is returned.

Reimplemented in Ogre::PCZSceneManager, and Ogre::OctreeSceneManager.

getOption()

virtual bool Ogre::SceneManager::getOption ( const String &  strKey, void *  pDestValue  )

inlinevirtual

Method for getting the value of an implementation-specific Scene Manager option.

Parameters

strKey	The name of the option
pDestValue	A pointer to a memory location where the value will be copied. Currently, the memory will be allocated by the scene manager, but this may change

Returns

On success, true is returned and pDestValue points to the value of the given option.

On failure, false is returned and pDestValue is set to NULL.

Reimplemented in Ogre::PCZSceneManager, and Ogre::OctreeSceneManager.

hasOption()

virtual bool Ogre::SceneManager::hasOption ( const String &  strKey ) const

inlinevirtual

Method for verifying whether the scene manager has an implementation-specific option.

Parameters

strKey

The name of the option to check for.

Returns

If the scene manager contains the given option, true is returned.

Remarks

If it does not, false is returned.

getOptionValues()

virtual bool Ogre::SceneManager::getOptionValues ( const String &  strKey, StringVector &  refValueList  )

inlinevirtual

Method for getting all possible values for a specific option.

When this list is too large (i.e. the option expects, for example, a float), the return value will be true, but the list will contain just one element whose size will be set to 0. Otherwise, the list will be filled with all the possible values the option can accept.

Parameters

strKey	The name of the option to get the values for.
refValueList	A reference to a list that will be filled with the available values.

Returns

On success (the option exists), true is returned.

On failure, false is returned.

Reimplemented in Ogre::PCZSceneManager, and Ogre::OctreeSceneManager.

getOptionKeys()

virtual bool Ogre::SceneManager::getOptionKeys ( StringVector &  refKeys )

inlinevirtual

Method for getting all the implementation-specific options of the scene manager.

Parameters

refKeys

A reference to a list that will be filled with all the available options.

Returns

On success, true is returned. On failure, false is returned.

_updateSceneGraph()

virtual void Ogre::SceneManager::_updateSceneGraph ( Camera *  cam )

virtual

Internal method for updating the scene graph ie the tree of SceneNode instances managed by this class.

Remarks

This must be done before issuing objects to the rendering pipeline, since derived transformations from parent nodes are not updated until required. This SceneManager is a basic implementation which simply updates all nodes from the root. This ensures the scene is up to date but requires all the nodes to be updated even if they are not visible. Subclasses could trim this such that only potentially visible nodes are updated.

Reimplemented in Ogre::PCZSceneManager, and Ogre::OctreeSceneManager.

_findVisibleObjects()

virtual void Ogre::SceneManager::_findVisibleObjects ( Camera *  cam, VisibleObjectsBoundsInfo *  visibleBounds, bool  onlyShadowCasters  )

virtual

Internal method which parses the scene to find visible objects to render.

Remarks

If you're implementing a custom scene manager, this is the most important method to override since it's here you can apply your custom world partitioning scheme. Once you have added the appropriate objects to the render queue, you can let the default SceneManager objects _renderVisibleObjects handle the actual rendering of the objects you pick.

Any visible objects will be added to a rendering queue, which is indexed by material in order to ensure objects with the same material are rendered together to minimise render state changes.

Reimplemented in Ogre::BspSceneManager, Ogre::PCZSceneManager, and Ogre::OctreeSceneManager.

_issueRenderOp()

void Ogre::SceneManager::_issueRenderOp	(	Renderable *	rend,
		const Pass *	pass
	)

Internal method for issuing the render operation.

_applySceneAnimations()

void Ogre::SceneManager::_applySceneAnimations

(

void

)

Internal method for applying animations to scene nodes.

Remarks

Uses the internally stored AnimationState objects to apply animation to SceneNodes.

_renderVisibleObjects()

void Ogre::SceneManager::_renderVisibleObjects

(

void

)

Sends visible objects found in _findVisibleObjects to the rendering engine.

_renderScene()

virtual void Ogre::SceneManager::_renderScene ( Camera *  camera, Viewport *  vp, bool  includeOverlays  )

virtual

Prompts the class to send its contents to the renderer.

Remarks

This method prompts the scene manager to send the contents of the scene it manages to the rendering pipeline, possibly preceded by some sorting, culling or other scene management tasks. Note that this method is not normally called directly by the user application; it is called automatically by the Ogre rendering loop.

Parameters

camera	Pointer to a camera from whose viewpoint the scene is to be rendered.
vp	The target viewport
includeOverlays	Whether or not overlay objects should be rendered

Reimplemented in Ogre::PCZSceneManager.

_queueSkiesForRendering()

void Ogre::SceneManager::_queueSkiesForRendering

(

Camera *

cam

)

_setDestinationRenderSystem()

void Ogre::SceneManager::_setDestinationRenderSystem

(

RenderSystem *

sys

)

Notifies the scene manager of its destination render system.

Remarks

Called automatically by RenderSystem::addSceneManager this method simply notifies the manager of the render system to which its output must be directed.

Parameters

sys	Pointer to the RenderSystem subclass to be used as a render target.

_releaseManualHardwareResources()

void Ogre::SceneManager::_releaseManualHardwareResources

(

)

Notifies the scene manager that hardware resources were lost.

Remarks

Called automatically by RenderSystem if hardware resources were lost and can not be restored using some internal mechanism. Among affected resources are manual meshes without loaders, manual textures without loaders, ManualObjects, etc.

_restoreManualHardwareResources()

void Ogre::SceneManager::_restoreManualHardwareResources

(

)

Notifies the scene manager that hardware resources should be restored.

Remarks

Called automatically by RenderSystem if hardware resources were lost and can not be restored using some internal mechanism. Among affected resources are manual meshes without loaders, manual textures without loaders, ManualObjects, etc.

setSkyPlane()

Ogre::SceneManager::setSkyPlane	(	bool	enable,
		const Plane &	plane,
		const String &	materialName,
		Real	scale = 1000,
		Real	tiling = 10,
		bool	drawFirst = true,
		Real	bow = 0,
		int	xsegments = 1,
		int	ysegments = 1,
		const String &	groupName = ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME
	)

Enables / disables a 'sky plane' i.e.

a plane at constant distance from the camera representing the sky.

Remarks

You can create sky planes yourself using the standard mesh and entity methods, but this creates a plane which the camera can never get closer or further away from - it moves with the camera. (NB you could create this effect by creating a world plane which was attached to the same SceneNode as the Camera too, but this would only apply to a single camera whereas this plane applies to any camera using this scene manager).

Note

To apply scaling, scrolls etc to the sky texture(s) you should use the TextureUnitState class methods.

Parameters

enable	True to enable the plane, false to disable it
plane	Details of the plane, i.e. it's normal and it's distance from the camera.
materialName	The name of the material the plane will use
scale	The scaling applied to the sky plane - higher values mean a bigger sky plane - you may want to tweak this depending on the size of plane.d and the other characteristics of your scene
tiling	How many times to tile the texture across the sky. Applies to all texture layers. If you need finer control use the TextureUnitState texture coordinate transformation methods.
drawFirst	If true, the plane is drawn before all other geometry in the scene, without updating the depth buffer. This is the safest rendering method since all other objects will always appear in front of the sky. However this is not the most efficient way if most of the sky is often occluded by other objects. If this is the case, you can set this parameter to false meaning it draws after all other geometry which can be an optimisation - however you must ensure that the plane.d value is large enough that no objects will 'poke through' the sky plane when it is rendered.
bow	If zero, the plane will be completely flat (like previous versions. If above zero, the plane will be curved, allowing the sky to appear below camera level. Curved sky planes are simular to skydomes, but are more compatible with fog.
xsegments,ysegments	Determines the number of segments the plane will have to it. This is most important when you are bowing the plane, but may also be useful if you need tessellation on the plane to perform per-vertex effects.
groupName	The name of the resource group to which to assign the plane mesh.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters

renderQueue

The render queue to use when rendering this object

setSkyBox()

Ogre::SceneManager::setSkyBox	(	bool	enable,
		const String &	materialName,
		Real	distance = 5000,
		bool	drawFirst = true,
		const Quaternion &	orientation = Quaternion::IDENTITY,
		const String &	groupName = ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME
	)

Enables / disables a 'sky box' i.e.

a 6-sided box at constant distance from the camera representing the sky.

Remarks

You could create a sky box yourself using the standard mesh and entity methods, but this creates a plane which the camera can never get closer or further away from - it moves with the camera. (NB you could create this effect by creating a world box which was attached to the same SceneNode as the Camera too, but this would only apply to a single camera whereas this skybox applies to any camera using this scene manager).

The material you use for the skybox can either contain layers which are single textures, or they can be cubic textures, i.e. made up of 6 images, one for each plane of the cube. See the TextureUnitState class for more information.

Parameters

enable	True to enable the skybox, false to disable it
materialName	The name of the material the box will use
distance	Distance in world coorinates from the camera to each plane of the box. The default is normally OK.
drawFirst	If true, the box is drawn before all other geometry in the scene, without updating the depth buffer. This is the safest rendering method since all other objects will always appear in front of the sky. However this is not the most efficient way if most of the sky is often occluded by other objects. If this is the case, you can set this parameter to false meaning it draws after all other geometry which can be an optimisation - however you must ensure that the distance value is large enough that no objects will 'poke through' the sky box when it is rendered.
renderQueue	The render queue to use when rendering this object
orientation	Optional parameter to specify the orientation of the box. By default the 'top' of the box is deemed to be in the +y direction, and the 'front' at the -z direction. You can use this parameter to rotate the sky if you want.
groupName	The name of the resource group to which to assign the plane mesh.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters

renderQueue

The render queue to use when rendering this object

_setSkyBox()

setSkyDome()

Ogre::SceneManager::setSkyDome	(	bool	enable,
		const String &	materialName,
		Real	curvature = 10,
		Real	tiling = 8,
		Real	distance = 4000,
		bool	drawFirst = true,
		const Quaternion &	orientation = Quaternion::IDENTITY,
		int	xsegments = 16,
		int	ysegments = 16,
		int	ysegments_keep = -1,
		const String &	groupName = ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME
	)

Enables / disables a 'sky dome' i.e.

an illusion of a curved sky.

Remarks

A sky dome is actually formed by 5 sides of a cube, but with texture coordinates generated such that the surface appears curved like a dome. Sky domes are appropriate where you need a realistic looking sky where the scene is not going to be 'fogged', and there is always a 'floor' of some sort to prevent the viewer looking below the horizon (the distortion effect below the horizon can be pretty horrible, and there is never anyhting directly below the viewer). If you need a complete wrap-around background, use the setSkyBox method instead. You can actually combine a sky box and a sky dome if you want, to give a positional backdrop with an overlayed curved cloud layer.

Sky domes work well with 2D repeating textures like clouds. You can change the apparent 'curvature' of the sky depending on how your scene is viewed - lower curvatures are better for 'open' scenes like landscapes, whilst higher curvatures are better for say FPS levels where you don't see a lot of the sky at once and the exaggerated curve looks good.

Parameters

enable	True to enable the skydome, false to disable it
materialName	The name of the material the dome will use
curvature	The curvature of the dome. Good values are between 2 and 65. Higher values are more curved leading to a smoother effect, lower values are less curved meaning more distortion at the horizons but a better distance effect.
tiling	How many times to tile the texture(s) across the dome.
distance	Distance in world coorinates from the camera to each plane of the box the dome is rendered on. The default is normally OK.
drawFirst	If true, the dome is drawn before all other geometry in the scene, without updating the depth buffer. This is the safest rendering method since all other objects will always appear in front of the sky. However this is not the most efficient way if most of the sky is often occluded by other objects. If this is the case, you can set this parameter to false meaning it draws after all other geometry which can be an optimisation - however you must ensure that the distance value is large enough that no objects will 'poke through' the sky when it is rendered.
orientation	Optional parameter to specify the orientation of the dome. By default the 'top' of the dome is deemed to be in the +y direction, and the 'front' at the -z direction. You can use this parameter to rotate the sky if you want.
groupName	The name of the resource group to which to assign the plane mesh.

createBillboardSet() [1/2]

BillboardSet* Ogre::SceneManager::createBillboardSet

(

unsigned int

poolSize = 20

)

Creates a new BillboardSet for use with this scene manager.

Remarks

This method creates a new BillboardSet which is registered with the SceneManager. The SceneManager will destroy this object when it shuts down or when the SceneManager::clearScene method is called, so the caller does not have to worry about destroying this object (in fact, it definitely should not do this).

See the BillboardSet documentations for full details of the returned class.

Parameters

poolSize

The initial size of the pool of billboards (see BillboardSet for more information)

See also

BillboardSet

createBillboardSet() [2/2]

BillboardSet* Ogre::SceneManager::createBillboardSet	(	const String &	name,
		unsigned int	poolSize = 20
	)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters

name	The name to give to this billboard set. Must be unique.

getBillboardSet()

BillboardSet* Ogre::SceneManager::getBillboardSet

(

const String &

name

)

const

Retrieves a pointer to the named BillboardSet.

Note

Throws an exception if the named instance does not exist

hasBillboardSet()

bool Ogre::SceneManager::hasBillboardSet

(

const String &

name

)

const

Returns whether a billboardset with the given name exists.

destroyBillboardSet() [1/2]

void Ogre::SceneManager::destroyBillboardSet

(

BillboardSet *

set

)

Removes & destroys an BillboardSet from the SceneManager.

Warning

Must only be done if the BillboardSet is not attached to a SceneNode. It may be safer to wait to clear the whole scene. If you are unsure, use clearScene.

destroyBillboardSet() [2/2]

void Ogre::SceneManager::destroyBillboardSet

(

const String &

name

)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

destroyAllBillboardSets()

void Ogre::SceneManager::destroyAllBillboardSets

(

void

)

Removes & destroys all BillboardSets.

Warning

Again, use caution since no BillboardSet must be referred to elsewhere e.g. attached to a SceneNode otherwise a crash is likely. Use clearScene if you are unsure (it clears SceneNode entries too.)

See also

SceneManager::clearScene

setDisplaySceneNodes()

void Ogre::SceneManager::setDisplaySceneNodes

(

bool

display

)

Tells the SceneManager whether it should render the SceneNodes which make up the scene as well as the objects in the scene.

Remarks

This method is mainly for debugging purposes. If you set this to 'true', each node will be rendered as a set of 3 axes to allow you to easily see the orientation of the nodes.

getDisplaySceneNodes()

bool Ogre::SceneManager::getDisplaySceneNodes ( void  ) const

inline

Returns true if all scene nodes axis are to be displayed.

createAnimation()

Animation* Ogre::SceneManager::createAnimation	(	const String &	name,
		Real	length
	)

Creates an animation which can be used to animate scene nodes.

Remarks

An animation is a collection of 'tracks' which over time change the position / orientation of Node objects. In this case, the animation will likely have tracks to modify the position / orientation of SceneNode objects, e.g. to make objects move along a path.

You don't need to use an Animation object to move objects around - you can do it yourself using the methods of the Node in your FrameListener class. However, when you need relatively complex scripted animation, this is the class to use since it will interpolate between keyframes for you and generally make the whole process easier to manage.

A single animation can affect multiple Node objects (each AnimationTrack affects a single Node). In addition, through animation blending a single Node can be affected by multiple animations, athough this is more useful when performing skeletal animation (see Skeleton::createAnimation).

Note that whilst it uses the same classes, the animations created here are kept separate from the skeletal animations of meshes (each Skeleton owns those animations).

Parameters

name	The name of the animation, must be unique within this SceneManager.
length	The total length of the animation.

getAnimation()

Animation* Ogre::SceneManager::getAnimation

(

const String &

name

)

const

Looks up an Animation object previously created with createAnimation.

Note

Throws an exception if the named instance does not exist

hasAnimation()

bool Ogre::SceneManager::hasAnimation

(

const String &

name

)

const

Returns whether an animation with the given name exists.

destroyAnimation()

void Ogre::SceneManager::destroyAnimation

(

const String &

name

)

Destroys an Animation.

Remarks

You should ensure that none of your code is referencing this animation objects since the memory will be freed.

destroyAllAnimations()

void Ogre::SceneManager::destroyAllAnimations

(

void

)

Removes all animations created using this SceneManager.

createAnimationState()

AnimationState* Ogre::SceneManager::createAnimationState

(

const String &

animName

)

Create an AnimationState object for managing application of animations.

Remarks

You can create Animation objects for animating SceneNode obejcts using the createAnimation method. However, in order to actually apply those animations you have to call methods on Node and Animation in a particular order (namely Node::resetToInitialState and Animation::apply). To make this easier and to help track the current time position of animations, the AnimationState object is provided. So if you don't want to control animation application manually, call this method, update the returned object as you like every frame and let SceneManager apply the animation state for you.

Remember, AnimationState objects are disabled by default at creation time. Turn them on when you want them using their setEnabled method.

Note that any SceneNode affected by this automatic animation will have it's state reset to it's initial position before application of the animation. Unless specifically modified using Node::setInitialState the Node assumes it's initial state is at the origin. If you want the base state of the SceneNode to be elsewhere, make your changes to the node using the standard transform methods, then call setInitialState to 'bake' this reference position into the node.

If the target of your animation is to be a generic AnimableValue, you should ensure that it has a base value set (unlike nodes this has no default).

See also

AnimableValue::setAsBaseValue.

Parameters

animName

The name of an animation created already with createAnimation.

getAnimationState()

AnimationState* Ogre::SceneManager::getAnimationState

(

const String &

animName

)

const

Retrieves animation state as previously created using createAnimationState.

Note

Throws an exception if the named instance does not exist

hasAnimationState()

bool Ogre::SceneManager::hasAnimationState

(

const String &

name

)

const

Returns whether an animation state with the given name exists.

destroyAnimationState()

void Ogre::SceneManager::destroyAnimationState

(

const String &

name

)

Destroys an AnimationState.

Remarks

You should ensure that none of your code is referencing this animation state object since the memory will be freed.

destroyAllAnimationStates()

void Ogre::SceneManager::destroyAllAnimationStates

(

void

)

Removes all animation states created using this SceneManager.

manualRender() [1/2]

void Ogre::SceneManager::manualRender	(	RenderOperation *	rend,
		Pass *	pass,
		Viewport *	vp,
		const Matrix4 &	worldMatrix,
		const Matrix4 &	viewMatrix,
		const Matrix4 &	projMatrix,
		bool	doBeginEndFrame = false
	)

Manual rendering method, for advanced users only.

Remarks

This method allows you to send rendering commands through the pipeline on demand, bypassing OGRE's normal world processing. You should only use this if you really know what you're doing; OGRE does lots of things for you that you really should let it do. However, there are times where it may be useful to have this manual interface, for example overlaying something on top of the scene rendered by OGRE.

Because this is an instant rendering method, timing is important. The best time to call it is from a RenderTargetListener event handler.

Don't call this method a lot, it's designed for rare (1 or 2 times per frame) use. Calling it regularly per frame will cause frame rate drops!

Parameters

rend	A RenderOperation object describing the rendering op
pass	The Pass to use for this render
vp	Pointer to the viewport to render to, or 0 to use the current viewport
worldMatrix	The transform to apply from object to world space
viewMatrix	The transform to apply from world to view space
projMatrix	The transform to apply from view to screen space
doBeginEndFrame	If true, beginFrame() and endFrame() are called, otherwise not. You should leave this as false if you are calling this within the main render loop.

manualRender() [2/2]

void Ogre::SceneManager::manualRender	(	Renderable *	rend,
		const Pass *	pass,
		Viewport *	vp,
		const Matrix4 &	viewMatrix,
		const Matrix4 &	projMatrix,
		bool	doBeginEndFrame = false,
		bool	lightScissoringClipping = true,
		bool	doLightIteration = true,
		const LightList *	manualLightList = 0
	)

Manual rendering method for rendering a single object.

Parameters

rend	The renderable to issue to the pipeline
pass	The pass to use
vp	Pointer to the viewport to render to, or 0 to use the existing viewport
doBeginEndFrame	If true, beginFrame() and endFrame() are called, otherwise not. You should leave this as false if you are calling this within the main render loop.
viewMatrix	The transform to apply from world to view space
projMatrix	The transform to apply from view to screen space
lightScissoringClipping	If true, passes that have the getLightScissorEnabled and/or getLightClipPlanesEnabled flags will cause calculation and setting of scissor rectangle and user clip planes.
doLightIteration	If true, this method will issue the renderable to the pipeline possibly multiple times, if the pass indicates it should be done once per light
manualLightList	Only applicable if doLightIteration is false, this method allows you to pass in a previously determined set of lights which will be used for a single render of this object.

getRenderQueue()

RenderQueue* Ogre::SceneManager::getRenderQueue

(

void

)

Retrieves the internal render queue, for advanced users only.

Remarks

The render queue is mainly used internally to manage the scene object rendering queue, it also exports some methods to allow advanced users to configure the behavior of rendering process. Most methods provided by RenderQueue are supposed to be used internally only, you should reference to the RenderQueue API for more information. Do not access this directly unless you know what you are doing.

addRenderQueueListener()

void Ogre::SceneManager::addRenderQueueListener

(

RenderQueueListener *

newListener

)

Registers a new RenderQueueListener which will be notified when render queues are processed.

removeRenderQueueListener()

void Ogre::SceneManager::removeRenderQueueListener

(

RenderQueueListener *

delListener

)

Removes a listener previously added with addRenderQueueListener.

addRenderObjectListener()

void Ogre::SceneManager::addRenderObjectListener

(

RenderObjectListener *

newListener

)

Registers a new Render Object Listener which will be notified when rendering an object.

removeRenderObjectListener()

void Ogre::SceneManager::removeRenderObjectListener

(

RenderObjectListener *

delListener

)

Removes a listener previously added with addRenderObjectListener.

addSpecialCaseRenderQueue()

void Ogre::SceneManager::addSpecialCaseRenderQueue

(

uint8

qid

)

Adds an item to the 'special case' render queue list.

Remarks

Normally all render queues are rendered, in their usual sequence, only varying if a RenderQueueListener nominates for the queue to be repeated or skipped. This method allows you to add a render queue to a 'special case' list, which varies the behaviour. The effect of this list depends on the 'mode' in which this list is in, which might be to exclude these render queues, or to include them alone (excluding all other queues). This allows you to perform broad selective rendering without requiring a RenderQueueListener.

Parameters

qid	The identifier of the queue which should be added to the special case list. Nothing happens if the queue is already in the list.

removeSpecialCaseRenderQueue()

void Ogre::SceneManager::removeSpecialCaseRenderQueue

(

uint8

qid

)

Removes an item to the 'special case' render queue list.

See also

SceneManager::addSpecialCaseRenderQueue

Parameters

qid	The identifier of the queue which should be removed from the special case list. Nothing happens if the queue is not in the list.

clearSpecialCaseRenderQueues()

void Ogre::SceneManager::clearSpecialCaseRenderQueues

(

void

)

Clears the 'special case' render queue list.

See also

SceneManager::addSpecialCaseRenderQueue

setSpecialCaseRenderQueueMode()

void Ogre::SceneManager::setSpecialCaseRenderQueueMode

(

SpecialCaseRenderQueueMode

mode

)

Sets the way the special case render queue list is processed.

See also

SceneManager::addSpecialCaseRenderQueue

Parameters

mode	The mode of processing

getSpecialCaseRenderQueueMode()

SpecialCaseRenderQueueMode Ogre::SceneManager::getSpecialCaseRenderQueueMode

(

void

)

Gets the way the special case render queue list is processed.

isRenderQueueToBeProcessed()

bool Ogre::SceneManager::isRenderQueueToBeProcessed

(

uint8

qid

)

Returns whether or not the named queue will be rendered based on the current 'special case' render queue list and mode.

See also

SceneManager::addSpecialCaseRenderQueue

Parameters

qid	The identifier of the queue which should be tested

Returns

true if the queue will be rendered, false otherwise

setWorldGeometryRenderQueue()

void Ogre::SceneManager::setWorldGeometryRenderQueue

(

uint8

qid

)

Sets the render queue that the world geometry (if any) this SceneManager renders will be associated with.

Remarks

SceneManagers which provide 'world geometry' should place it in a specialised render queue in order to make it possible to enable / disable it easily using the addSpecialCaseRenderQueue method. Even if the SceneManager does not use the render queues to render the world geometry, it should still pick a queue to represent it's manual rendering, and check isRenderQueueToBeProcessed before rendering.

Note

Setting this may not affect the actual ordering of rendering the world geometry, if the world geometry is being rendered manually by the SceneManager. If the SceneManager feeds world geometry into the queues, however, the ordering will be affected.

getWorldGeometryRenderQueue()

uint8 Ogre::SceneManager::getWorldGeometryRenderQueue

(

void

)

Gets the render queue that the world geometry (if any) this SceneManager renders will be associated with.

Remarks

SceneManagers which provide 'world geometry' should place it in a specialised render queue in order to make it possible to enable / disable it easily using the addSpecialCaseRenderQueue method. Even if the SceneManager does not use the render queues to render the world geometry, it should still pick a queue to represent it's manual rendering, and check isRenderQueueToBeProcessed before rendering.

bool

bShow

)

References Ogre::AnimationStateSet::getAnimationStates().

setShadowTechnique()

void Ogre::SceneManager::setShadowTechnique

(

ShadowTechnique

technique

)

Sets the general shadow technique to be used in this scene.

Remarks

There are multiple ways to generate shadows in a scene, and each has strengths and weaknesses.

• Stencil-based approaches can be used to draw very long, extreme shadows without loss of precision and the 'additive' version can correctly show the shadowing of complex effects like bump mapping because they physically exclude the light from those areas. However, the edges are very sharp and stencils cannot handle transparency, and they involve a fair amount of CPU work in order to calculate the shadow volumes, especially when animated objects are involved.
• Texture-based approaches are good for handling transparency (they can, for example, correctly shadow a mesh which uses alpha to represent holes), and they require little CPU overhead, and can happily shadow geometry which is deformed by a vertex program, unlike stencil shadows. However, they have a fixed precision which can introduce 'jaggies' at long range and have fillrate issues of their own.

We support 2 kinds of stencil shadows, and 2 kinds of texture-based shadows, and one simple decal approach. The 2 stencil approaches differ in the amount of multipass work that is required - the modulative approach simply 'darkens' areas in shadow after the main render, which is the least expensive, whilst the additive approach has to perform a render per light and adds the cumulative effect, which is more expensive but more accurate. The texture based shadows both work in roughly the same way, the only difference is that the shadowmap approach is slightly more accurate, but requires a more recent graphics card.

Note that because mixing many shadow techniques can cause problems, only one technique is supported at once. Also, you should call this method at the start of the scene setup.

Parameters

technique

The shadowing technique to use for the scene.

getShadowTechnique()

ShadowTechnique Ogre::SceneManager::getShadowTechnique ( void  ) const

inline

Gets the current shadow technique.

setShowDebugShadows()

void Ogre::SceneManager::setShowDebugShadows ( bool  debug )

inline

Enables / disables the rendering of debug information for shadows.

getShowDebugShadows()

bool Ogre::SceneManager::getShowDebugShadows ( void  ) const

inline

Are debug shadows shown?

setShadowColour()

void Ogre::SceneManager::setShadowColour

(

const ColourValue &

colour

)

Set the colour used to modulate areas in shadow.

Remarks

This is only applicable for shadow techniques which involve darkening the area in shadow, as opposed to masking out the light. This colour provided is used as a modulative value to darken the areas.

getShadowColour()

const ColourValue& Ogre::SceneManager::getShadowColour

(

void

)

const

Get the colour used to modulate areas in shadow.

Remarks

This is only applicable for shadow techniques which involve darkening the area in shadow, as opposed to masking out the light. This colour provided is used as a modulative value to darken the areas.

setShadowDirectionalLightExtrusionDistance()

void Ogre::SceneManager::setShadowDirectionalLightExtrusionDistance

(

Real

dist

)

Sets the distance a shadow volume is extruded for a directional light.

Remarks

Although directional lights are essentially infinite, there are many reasons to limit the shadow extrusion distance to a finite number, not least of which is compatibility with older cards (which do not support infinite positions), and shadow caster elimination.

The default value is 10,000 world units. This does not apply to point lights or spotlights, since they extrude up to their attenuation range.

getShadowDirectionalLightExtrusionDistance()

Real Ogre::SceneManager::getShadowDirectionalLightExtrusionDistance

(

void

)

const

Gets the distance a shadow volume is extruded for a directional light.

setShadowFarDistance()

void Ogre::SceneManager::setShadowFarDistance

(

Real

distance

)

Sets the default maximum distance away from the camera that shadows will be visible.

You have to call this function before you create lights or the default distance of zero will be used.

Remarks

Shadow techniques can be expensive, therefore it is a good idea to limit them to being rendered close to the camera if possible, and to skip the expense of rendering shadows for distance objects. This method allows you to set the distance at which shadows will no longer be rendered.

Note

Each shadow technique can interpret this subtely differently. For example, one technique may use this to eliminate casters, another might use it to attenuate the shadows themselves. You should tweak this value to suit your chosen shadow technique and scene setup.

getShadowFarDistance()

Real Ogre::SceneManager::getShadowFarDistance ( void  ) const

inline

Gets the default maximum distance away from the camera that shadows will be visible.

getShadowFarDistanceSquared()

Real Ogre::SceneManager::getShadowFarDistanceSquared ( void  ) const

inline

setShadowIndexBufferSize()

void Ogre::SceneManager::setShadowIndexBufferSize

(

size_t

size

)

Sets the maximum size of the index buffer used to render shadow primitives.

Remarks

This method allows you to tweak the size of the index buffer used to render shadow primitives (including stencil shadow volumes). The default size is 51,200 entries, which is 100k of GPU memory, or enough to render approximately 17,000 triangles. You can reduce this as long as you do not have any models / world geometry chunks which could require more than the amount you set.

The maximum number of triangles required to render a single shadow volume (including light and dark caps when needed) will be 3x the number of edges on the light silhouette, plus the number of light-facing triangles. On average, half the triangles will be facing toward the light, but the number of triangles in the silhouette entirely depends on the mesh - angular meshes will have a higher silhouette tris/mesh tris ratio than a smooth mesh. You can estimate the requirements for your particular mesh by rendering it alone in a scene with shadows enabled and a single light - rotate it or the light and make a note of how high the triangle count goes (remembering to subtract the mesh triangle count)

Parameters

size	The number of indexes; divide this by 3 to determine the number of triangles.

getShadowIndexBufferSize()

size_t Ogre::SceneManager::getShadowIndexBufferSize ( void  ) const

inline

Get the size of the shadow index buffer.

setShadowTextureSize()

void Ogre::SceneManager::setShadowTextureSize

(

unsigned short

size

)

Set the size of the texture used for all texture-based shadows.

Remarks

The larger the shadow texture, the better the detail on texture based shadows, but obviously this takes more memory. The default size is 512. Sizes must be a power of 2.

Note

This is the simple form, see setShadowTextureConfig for the more complex form.

setShadowTextureConfig() [1/2]

void Ogre::SceneManager::setShadowTextureConfig	(	size_t	shadowIndex,
		unsigned short	width,
		unsigned short	height,
		PixelFormat	format,
		unsigned short	fsaa = 0,
		uint16	depthBufferPoolId = 1
	)

Set the detailed configuration for a shadow texture.

Parameters

shadowIndex	The index of the texture to configure, must be < the number of shadow textures setting
width	The width of the texture
height	The height of the texture
format	The pixel format of the texture
fsaa	The level of multisampling to use. Ignored if the device does not support it.
depthBufferPoolId	The pool # it should query the depth buffers from

setShadowTextureConfig() [2/2]

void Ogre::SceneManager::setShadowTextureConfig	(	size_t	shadowIndex,
		const ShadowTextureConfig &	config
	)

Set the detailed configuration for a shadow texture.

Parameters

shadowIndex	The index of the texture to configure, must be < the number of shadow textures setting
config	Configuration structure

getShadowTextureConfigIterator()

ConstShadowTextureConfigIterator Ogre::SceneManager::getShadowTextureConfigIterator

(

)

const

Get an iterator over the current shadow texture settings.

setShadowTexturePixelFormat()

void Ogre::SceneManager::setShadowTexturePixelFormat

(

PixelFormat

fmt

)

Set the pixel format of the textures used for texture-based shadows.

Remarks

By default, a colour texture is used (PF_X8R8G8B8) for texture shadows, but if you want to use more advanced texture shadow types you can alter this. If you do, you will have to also call setShadowTextureCasterMaterial and setShadowTextureReceiverMaterial to provide shader-based materials to use these customised shadow texture formats.

Note

This is the simple form, see setShadowTextureConfig for the more complex form.

setShadowTextureFSAA()

void Ogre::SceneManager::setShadowTextureFSAA

(

unsigned short

fsaa

)

Set the level of multisample AA of the textures used for texture-based shadows.

Remarks

By default, the level of multisample AA is zero.

Note

This is the simple form, see setShadowTextureConfig for the more complex form.

setShadowTextureCount()

void Ogre::SceneManager::setShadowTextureCount

(

size_t

count

)

Set the number of textures allocated for texture-based shadows.

Remarks

The default number of textures assigned to deal with texture based shadows is 1; however this means you can only have one light casting shadows at the same time. You can increase this number in order to make this more flexible, but be aware of the texture memory it will use.

getShadowTextureCount()

size_t Ogre::SceneManager::getShadowTextureCount ( void  ) const

inline

Get the number of the textures allocated for texture based shadows.

setShadowTextureCountPerLightType()

void Ogre::SceneManager::setShadowTextureCountPerLightType ( Light::LightTypes  type, size_t  count  )

inline

Set the number of shadow textures a light type uses.

Remarks

The default for all light types is 1. This means that each light uses only 1 shadow texture. Call this if you need more than 1 shadow texture per light, E.G. PSSM.

Note

This feature only works with the Integrated shadow technique. Also remember to increase the total number of shadow textures you request appropriately (e.g. via setShadowTextureCount)!!

getShadowTextureCountPerLightType()

size_t Ogre::SceneManager::getShadowTextureCountPerLightType ( Light::LightTypes  type ) const

inline

Get the number of shadow textures is assigned for the given light type.

References Ogre::PF_X8R8G8B8.

setShadowTextureSettings()

void Ogre::SceneManager::setShadowTextureSettings	(	unsigned short	size,
		unsigned short	count,
		PixelFormat	fmt = PF_X8R8G8B8,
		unsigned short	fsaa = 0,
		uint16	depthBufferPoolId = 1
	)

Sets the size and count of textures used in texture-based shadows.

See also

setShadowTextureSize and setShadowTextureCount for details, this method just allows you to change both at once, which can save on reallocation if the textures have already been created.

Note

This is the simple form, see setShadowTextureConfig for the more complex form.

getShadowTexture()

const TexturePtr& Ogre::SceneManager::getShadowTexture

(

size_t

shadowIndex

)

Get a reference to the shadow texture currently in use at the given index.

Note

If you change shadow settings, this reference may no longer be correct, so be sure not to hold the returned reference over texture shadow configuration changes.

setShadowDirLightTextureOffset()

void Ogre::SceneManager::setShadowDirLightTextureOffset ( Real  offset )

inline

Sets the proportional distance which a texture shadow which is generated from a directional light will be offset into the camera view to make best use of texture space.

Remarks

When generating a shadow texture from a directional light, an approximation is used since it is not possible to render the entire scene to one texture. The texture is projected onto an area centred on the camera, and is the shadow far distance * 2 in length (it is square). This wastes a lot of texture space outside the frustum though, so this offset allows you to move the texture in front of the camera more. However, be aware that this can cause a little shadow 'jittering' during rotation, and that if you move it too far then you'll start to get artefacts close to the camera. The value is represented as a proportion of the shadow far distance, and the default is 0.6.

getShadowDirLightTextureOffset()

Real Ogre::SceneManager::getShadowDirLightTextureOffset ( void  ) const

inline

Gets the proportional distance which a texture shadow which is generated from a directional light will be offset into the camera view to make best use of texture space.

setShadowTextureFadeStart()

void Ogre::SceneManager::setShadowTextureFadeStart ( Real  fadeStart )

inline

Sets the proportional distance at which texture shadows begin to fade out.

Remarks

To hide the edges where texture shadows end (in directional lights) Ogre will fade out the shadow in the distance. This value is a proportional distance of the entire shadow visibility distance at which the shadow begins to fade out. The default is 0.7

setShadowTextureFadeEnd()

void Ogre::SceneManager::setShadowTextureFadeEnd ( Real  fadeEnd )

inline

Sets the proportional distance at which texture shadows finish to fading out.

Remarks

To hide the edges where texture shadows end (in directional lights) Ogre will fade out the shadow in the distance. This value is a proportional distance of the entire shadow visibility distance at which the shadow is completely invisible. The default is 0.9.

setShadowTextureSelfShadow()

void Ogre::SceneManager::setShadowTextureSelfShadow

(

bool

selfShadow

)

Sets whether or not texture shadows should attempt to self-shadow.

Remarks

The default implementation of texture shadows uses a fixed-function colour texture projection approach for maximum compatibility, and as such cannot support self-shadowing. However, if you decide to implement a more complex shadowing technique using the setShadowTextureCasterMaterial and setShadowTextureReceiverMaterial there is a possibility you may be able to support self-shadowing (e.g by implementing a shader-based shadow map). In this case you might want to enable this option.

Parameters

selfShadow

Whether to attempt self-shadowing with texture shadows

getShadowTextureSelfShadow()

bool Ogre::SceneManager::getShadowTextureSelfShadow ( void  ) const

inline

Gets whether or not texture shadows attempt to self-shadow.

setShadowTextureCasterMaterial() [1/2]

void Ogre::SceneManager::setShadowTextureCasterMaterial

(

const MaterialPtr &

mat

)

Sets the default material to use for rendering shadow casters.

Remarks

By default shadow casters are rendered into the shadow texture using an automatically generated fixed-function pass. This allows basic projective texture shadows, but it's possible to use more advanced shadow techniques by overriding the caster and receiver materials, for example providing vertex and fragment programs to implement shadow maps.

You can rely on the ambient light in the scene being set to the requested texture shadow colour, if that's useful.

Note

Individual objects may also override the vertex program in your default material if their materials include shadow_caster_vertex_program_ref, shadow_receiver_vertex_program_ref shadow_caster_material entries, so if you use both make sure they are compatible.

Only a single pass is allowed in your material, although multiple techniques may be used for hardware fallback.

setShadowTextureCasterMaterial() [2/2]

void Ogre::SceneManager::setShadowTextureCasterMaterial

(

const String &

name

)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Deprecated:

use setShadowTextureCasterMaterial(const MaterialPtr&)

setShadowTextureReceiverMaterial() [1/2]

void Ogre::SceneManager::setShadowTextureReceiverMaterial

(

const MaterialPtr &

mat

)

Sets the default material to use for rendering shadow receivers.

Remarks

By default shadow receivers are rendered as a post-pass using basic modulation. This allows basic projective texture shadows, but it's possible to use more advanced shadow techniques by overriding the caster and receiver materials, for example providing vertex and fragment programs to implement shadow maps.

You can rely on texture unit 0 containing the shadow texture, and for the unit to be set to use projective texturing from the light (only useful if you're using fixed-function, which is unlikely; otherwise you should rely on the texture_viewproj_matrix auto binding)

Note

Individual objects may also override the vertex program in your default material if their materials include shadow_caster_vertex_program_ref shadow_receiver_vertex_program_ref shadow_receiver_material entries, so if you use both make sure they are compatible.

Only a single pass is allowed in your material, although multiple techniques may be used for hardware fallback.

setShadowTextureReceiverMaterial() [2/2]

void Ogre::SceneManager::setShadowTextureReceiverMaterial

(

const String &

name

)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Deprecated:

use setShadowTextureReceiverMaterial(const MaterialPtr&)

setShadowCasterRenderBackFaces()

void Ogre::SceneManager::setShadowCasterRenderBackFaces ( bool  bf )

inline

Sets whether or not shadow casters should be rendered into shadow textures using their back faces rather than their front faces.

Remarks

Rendering back faces rather than front faces into a shadow texture can help minimise depth comparison issues, if you're using depth shadowmapping. You will probably still need some biasing but you won't need as much. For solid objects the result is the same anyway, if you have objects with holes you may want to turn this option off. The default is to enable this option.

getShadowCasterRenderBackFaces()

bool Ogre::SceneManager::getShadowCasterRenderBackFaces ( ) const

inline

Gets whether or not shadow casters should be rendered into shadow textures using their back faces rather than their front faces.

setShadowCameraSetup()

void Ogre::SceneManager::setShadowCameraSetup

(

const ShadowCameraSetupPtr &

shadowSetup

)

const ShadowCameraSetupPtr& Ogre::SceneManager::getShadowCameraSetup

(

)

const

setShadowUseInfiniteFarPlane()

void Ogre::SceneManager::setShadowUseInfiniteFarPlane ( bool  enable )

inline

Sets whether we should use an inifinite camera far plane when rendering stencil shadows.

Remarks

Stencil shadow coherency is very reliant on the shadow volume not being clipped by the far plane. If this clipping happens, you get a kind of 'negative' shadow effect. The best way to achieve coherency is to move the far plane of the camera out to infinity, thus preventing the far plane from clipping the shadow volumes. When combined with vertex program extrusion of the volume to infinity, which Ogre does when available, this results in very robust shadow volumes. For this reason, when you enable stencil shadows, Ogre automatically changes your camera settings to project to infinity if the card supports it. You can disable this behaviour if you like by calling this method; although you can never enable infinite projection if the card does not support it.

If you disable infinite projection, or it is not available, you need to be far more careful with your light attenuation / directional light extrusion distances to avoid clipping artefacts at the far plane.

Note

Recent cards will generally support infinite far plane projection. However, we have found some cases where they do not, especially on Direct3D. There is no standard capability we can check to validate this, so we use some heuristics based on experience:

• OpenGL always seems to support it no matter what the card
• Direct3D on non-vertex program capable systems (including vertex program capable cards on Direct3D7) does not support it
• Direct3D on GeForce3 and GeForce4 Ti does not seem to support infinite projection

Therefore in the RenderSystem implementation, we may veto the use of an infinite far plane based on these heuristics.

(

MovableObject *

m

)

Inject a MovableObject instance created externally.

Remarks

This method 'injects' a MovableObject instance created externally into the MovableObject instance registry held in the SceneManager. You might want to use this if you have a MovableObject which you don't want to register a factory for; for example a MovableObject which cannot be generally constructed by clients.

Note

It is important that the MovableObject has a unique name for the type, and that its getMovableType() method returns a proper type name.

extractMovableObject() [1/2]

void Ogre::SceneManager::extractMovableObject	(	const String &	name,
		const String &	typeName
	)

Extract a previously injected MovableObject.

Remarks

Essentially this does the same as destroyMovableObject, but only removes the instance from the internal lists, it does not attempt to destroy it.

extractMovableObject() [2/2]

(

MovableObject *

m

)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

extractAllMovableObjectsByType()

void Ogre::SceneManager::extractAllMovableObjectsByType

(

const String &

typeName

)

Extract all injected MovableObjects of a given type.

inline

Gets whether the SceneManager should search for visible objects, or whether they are being manually handled.

setNormaliseNormalsOnScale()

void Ogre::SceneManager::setNormaliseNormalsOnScale ( bool  n )

inline

Set whether to automatically normalise normals on objects whenever they are scaled.

Remarks

Scaling can distort normals so the default behaviour is to compensate for this, but it has a cost. If you would prefer to manually manage this, set this option to 'false' and use Pass::setNormaliseNormals only when needed.

getNormaliseNormalsOnScale()

bool Ogre::SceneManager::getNormaliseNormalsOnScale ( ) const

inline

Get whether to automatically normalise normals on objects whenever they are scaled.

setFlipCullingOnNegativeScale()

void Ogre::SceneManager::setFlipCullingOnNegativeScale ( bool  n )

inline

Set whether to automatically flip the culling mode on objects whenever they are negatively scaled.

Remarks

Negativelyl scaling an object has the effect of flipping the triangles, so the culling mode should probably be inverted to deal with this. If you would prefer to manually manage this, set this option to 'false' and use different materials with Pass::setCullingMode set manually as needed.

getFlipCullingOnNegativeScale()

bool Ogre::SceneManager::getFlipCullingOnNegativeScale ( ) const

inline

Get whether to automatically flip the culling mode on objects whenever they are negatively scaled.

_injectRenderWithPass()

void Ogre::SceneManager::_injectRenderWithPass	(	Pass *	pass,

_suppressRenderStateChanges()

void Ogre::SceneManager::_suppressRenderStateChanges

(

bool

suppress

)

Indicates to the SceneManager whether it should suppress changing the RenderSystem states when rendering objects.

Remarks

This method allows you to tell the SceneManager not to change any RenderSystem state until you tell it to. This method is only intended for advanced use, don't use it if you're unsure of the effect. The only RenderSystems calls made are to set the world matrix for each object (note - view an projection matrices are NOT SET - they are under your control) and to render the object; it is up to the caller to do everything else, including enabling any vertex / fragment programs and updating their parameter state, and binding parameters to the RenderSystem.

Note

Calling this implicitly disables shadow processing since no shadows can be rendered without changing state.

Parameters

suppress

If true, no RenderSystem state changes will be issued until this method is called again with a parameter of false.

_areRenderStateChangesSuppressed()

bool Ogre::SceneManager::_areRenderStateChangesSuppressed ( void  ) const

inline

Are render state changes suppressed?

See also

_suppressRenderStateChanges

_setPass()

const Pass* Ogre::SceneManager::_setPass	(	const Pass *	pass,
		bool	evenIfSuppressed = false,
		bool	shadowDerivation = true
	)

Internal method for setting up the renderstate for a rendering pass.

Parameters

pass	The Pass details to set.
evenIfSuppressed	Sets the pass details even if render state changes are suppressed; if you are using this to manually set state when render state changes are suppressed, you should set this to true.
shadowDerivation	If false, disables the derivation of shadow passes from original passes

Returns

A Pass object that was used instead of the one passed in, can happen when rendering shadow passes

_markGpuParamsDirty()

void Ogre::SceneManager::_markGpuParamsDirty

(

uint16

mask

)

Method to allow you to mark gpu parameters as dirty, causing them to be updated according to the mask that you set when updateGpuProgramParameters is next called.

Only really useful if you're controlling parameter state in inner rendering loop callbacks.

Parameters

mask	Some combination of GpuParamVariability which is bitwise OR'ed with the current dirty state.

_suppressShadows()

void Ogre::SceneManager::_suppressShadows

(

bool

suppress

)

Indicates to the SceneManager whether it should suppress the active shadow rendering technique until told otherwise.

Remarks

This is a temporary alternative to setShadowTechnique to suppress the rendering of shadows and forcing all processing down the standard rendering path. This is intended for internal use only.

Parameters

suppress

If true, no shadow rendering will occur until this method is called again with a parameter of false.

_areShadowsSuppressed()

bool Ogre::SceneManager::_areShadowsSuppressed ( void  ) const

inline

Are shadows suppressed?

See also

_suppressShadows

_renderQueueGroupObjects()

void Ogre::SceneManager::_renderQueueGroupObjects	(	RenderQueueGroup *	group,
		QueuedRenderableCollection::OrganisationMode	om
	)

Render the objects in a given queue group.

Remarks

You should only call this from a RenderQueueInvocation implementation

setQueuedRenderableVisitor()

void Ogre::SceneManager::setQueuedRenderableVisitor

(

SceneMgrQueuedRenderableVisitor *

visitor

)

Advanced method for supplying an alternative visitor, used for parsing the render queues and sending the results to the renderer.

Remarks

You can use this method to insert your own implementation of the QueuedRenderableVisitor interface, which receives calls as the queued renderables are parsed in a given order (determined by RenderQueueInvocationSequence) and are sent to the renderer. If you provide your own implementation of this visitor, you are responsible for either calling the rendersystem, or passing the calls on to the base class implementation.

Note

Ownership is not taken of this pointer, you are still required to delete it yourself once you're finished.

Parameters

visitor

Your implementation of SceneMgrQueuedRenderableVisitor. If you pass 0, the default implementation will be used.

getQueuedRenderableVisitor()

SceneMgrQueuedRenderableVisitor* Ogre::SceneManager::getQueuedRenderableVisitor

(

void

)

const

Gets the current visitor object which processes queued renderables.

getDestinationRenderSystem()

RenderSystem* Ogre::SceneManager::getDestinationRenderSystem

(

)

Get the rendersystem subclass to which the output of this Scene Manager gets sent.

getCurrentViewport()

Viewport* Ogre::SceneManager::getCurrentViewport ( void  ) const

inline

Gets the current viewport being rendered (advanced use only, only valid during viewport update.

getVisibleObjectsBoundsInfo()

const VisibleObjectsBoundsInfo& Ogre::SceneManager::getVisibleObjectsBoundsInfo

(

const Camera *

cam

)

const

Returns a visibility boundary box for a specific camera.

getShadowCasterBoundsInfo()

const VisibleObjectsBoundsInfo& Ogre::SceneManager::getShadowCasterBoundsInfo	(	const Light *	light,
		size_t	iteration = 0
	)		const

Returns the shadow caster AAB for a specific light-camera combination.

setCameraRelativeRendering()

void Ogre::SceneManager::setCameraRelativeRendering ( bool  rel )

inline

Set whether to use camera-relative co-ordinates when rendering, ie to always place the camera at the origin and move the world around it.

Remarks

This is a technique to alleviate some of the precision issues associated with rendering far from the origin, where single-precision floats as used in most GPUs begin to lose their precision. Instead of including the camera translation in the view matrix, it only includes the rotation, and the world matrices of objects must be expressed relative to this.

Note

If you need this option, you will probably also need to enable double-precision mode in Ogre (OGRE_DOUBLE_PRECISION), since even though this will alleviate the rendering precision, the source camera and object positions will still suffer from precision issues leading to jerky movement.

getCameraRelativeRendering()

bool Ogre::SceneManager::getCameraRelativeRendering ( ) const

inline

Get whether to use camera-relative co-ordinates when rendering, ie to always place the camera at the origin and move the world around it.

addLodListener()

void Ogre::SceneManager::addLodListener

(

LodListener *

listener

)

Add a level of detail listener.

removeLodListener()

void Ogre::SceneManager::removeLodListener

(

LodListener *

listener

)

Remarks

Do not call from inside an LodListener callback method.

_notifyMovableObjectLodChanged()

void Ogre::SceneManager::_notifyMovableObjectLodChanged

(

MovableObjectLodChangedEvent &

evt

)

Notify that a movable object LOD change event has occurred.

_notifyEntityMeshLodChanged()

void Ogre::SceneManager::_notifyEntityMeshLodChanged

(

EntityMeshLodChangedEvent &

evt

)
