◆ OGRE_MUTEX()

Ogre::SceneManager::OGRE_MUTEX ( sceneGraphMutex  )
inherited

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.

◆ prepareShadowTextures()

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

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.

virtualinherited

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.

inherited

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
inlineinherited

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
inherited

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 
)
inherited

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
positionThe position at which to evaluate the list of lights
radiusThe bounding radius to test
destListList to be populated with ordered set of lights; will be cleared by this method before population.
lightMaskThe mask with which to include / exclude lights

◆ _populateLightList() [2/2]

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

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
snThe SceneNode for which to evaluate the list of lights
radiusThe bounding radius to test
destListList to be populated with ordered set of lights; will be cleared by this method before population.
lightMaskThe mask with which to include / exclude lights

◆ createSceneNode() [1/2]

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

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)
virtualinherited

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() [2/2]

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

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.

◆ getRootSceneNode()

SceneNode* Ogre::SceneManager::getRootSceneNode ( void  )
inherited

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
inherited

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.

◆ createParticleSystem() [1/3]

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

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
nameThe name to give the new particle system instance.
templateNameThe 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 
)
inherited

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
nameThe name to give the ParticleSystem.
quotaThe maximum number of particles to allow in this system.
resourceGroupThe 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 
)
inherited

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.
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
quotaThe maximum number of particles to allow in this system.
resourceGroupThe resource group which will be used to load dependent resources

◆ getParticleSystem()

ParticleSystem* Ogre::SceneManager::getParticleSystem ( const String name) const
inherited

void Ogre::SceneManager::destroyAllParticleSystems ( void  )
inherited

Removes & destroys all ParticleSystems from the SceneManager.

◆ setAmbientLight()

void Ogre::SceneManager::setAmbientLight ( const ColourValue colour)
inherited

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
inherited

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

◆ prepareWorldGeometry() [1/2]

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

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 
)
virtualinherited

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

Parameters
streamData stream containing data to load
typeNameString 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)
virtualinherited

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 
)
virtualinherited

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

Parameters
streamData stream containing data to load
typeNameString 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)
inlinevirtualinherited

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 
)
inlinevirtualinherited

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

Parameters
streamData stream containing data to load
typeNameString 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)
virtualinherited

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
randomIf 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.

◆ hasOption()

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

◆ _renderVisibleObjects()

void Ogre::SceneManager::_renderVisibleObjects ( void  )
inherited

◆ _renderScene()

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

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
cameraPointer to a camera from whose viewpoint the scene is to be rendered.
vpThe target viewport
includeOverlaysWhether or not overlay objects should be rendered

Reimplemented in Ogre::PCZSceneManager.

◆ _queueSkiesForRendering()

◆ _setDestinationRenderSystem()

void Ogre::SceneManager::_setDestinationRenderSystem ( RenderSystem sys)
inherited

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
sysPointer to the RenderSystem subclass to be used as a render target.

◆ _releaseManualHardwareResources()

void Ogre::SceneManager::_releaseManualHardwareResources ( )
inherited

Notifies the scene manager that hardware resources were lost.

Remarks

◆ _restoreManualHardwareResources()

void Ogre::SceneManager::_restoreManualHardwareResources ( )
inherited

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 
)
inherited

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
enableTrue to enable the plane, false to disable it
planeDetails of the plane, i.e. it's normal and it's distance from the camera.
materialNameThe name of the material the plane will use
scaleThe 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
tilingHow 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.
drawFirstIf 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.
bowIf 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,ysegmentsDetermines 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.
groupNameThe 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
renderQueueThe render queue to use when rendering this object

const String materialName,
Real  distance = 5000,
bool  drawFirst = true,
const Quaternion orientation = Quaternion::IDENTITY,
const String groupName = ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME 
)
inherited

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
enableTrue to enable the skybox, false to disable it
materialNameThe name of the material the box will use
distanceDistance in world coorinates from the camera to each plane of the box. The default is normally OK.
drawFirstIf 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.
renderQueueThe render queue to use when rendering this object
orientationOptional 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.
groupNameThe 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
renderQueueThe render queue to use when rendering this object

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 
)
inherited

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
enableTrue to enable the skydome, false to disable it
materialNameThe name of the material the dome will use
curvatureThe 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.
tilingHow many times to tile the texture(s) across the dome.
distanceDistance in world coorinates from the camera to each plane of the box the dome is rendered on. The default is normally OK.
drawFirstIf 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.
orientationOptional 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.
groupNameThe 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.

const ColourValue colour = ColourValue::White,
Real  expDensity = 0.001,
Real  linearStart = 0.0,
Real  linearEnd = 1.0 
)
inherited

Sets the fogging mode applied to the scene.

Remarks
This method sets up the scene-wide fogging effect. These settings apply to all geometry rendered, UNLESS the material with which it is rendered has it's own fog settings (see Material::setFog).
Parameters
modeSet up the mode of fog as described in the FogMode enum, or set to FOG_NONE to turn off.
colourThe colour of the fog. Either set this to the same as your viewport background colour, or to blend in with a skydome or skybox.
expDensityThe density of the fog in FOG_EXP or FOG_EXP2 mode, as a value between 0 and 1. The default is 0.001.
linearStartDistance in world units at which linear fog starts to encroach. Only applicable if mode is FOG_LINEAR.
linearEndDistance in world units at which linear fog becomes completely opaque. Only applicable if mode is FOG_LINEAR.

◆ createBillboardSet() [1/2]

BillboardSet* Ogre::SceneManager::createBillboardSet ( unsigned int  poolSize = 20)
inherited

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
poolSizeThe 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 
)
inherited

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

Parameters
nameThe name to give to this billboard set. Must be unique.

◆ getBillboardSet()

BillboardSet* Ogre::SceneManager::getBillboardSet ( const String name) const
inherited

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
inherited

Returns whether a billboardset with the given name exists.

◆ destroyBillboardSet() [1/2]

void Ogre::SceneManager::destroyBillboardSet ( BillboardSet set)
inherited

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)
inherited

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  )
inherited

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)
inherited

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
inlineinherited

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

◆ createAnimation()

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

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

◆ getAnimation()

Animation* Ogre::SceneManager::getAnimation ( const String name) const
inherited

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
inherited

Returns whether an animation with the given name exists.

◆ destroyAnimation()

void Ogre::SceneManager::destroyAnimation ( const String name)
inherited

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  )
inherited

Removes all animations created using this SceneManager.

◆ createAnimationState()

AnimationState* Ogre::SceneManager::createAnimationState ( const String animName)
inherited

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
animNameThe name of an animation created already with createAnimation.

◆ getAnimationState()

AnimationState* Ogre::SceneManager::getAnimationState ( const String animName) const
inherited

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
inherited

Returns whether an animation state with the given name exists.

◆ destroyAnimationState()

void Ogre::SceneManager::destroyAnimationState ( const String name)
inherited

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  )
inherited

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 
)
inherited

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
rendA RenderOperation object describing the rendering op
passThe Pass to use for this render
vpPointer to the viewport to render to, or 0 to use the current viewport
worldMatrixThe transform to apply from object to world space
viewMatrixThe transform to apply from world to view space
projMatrixThe transform to apply from view to screen space
doBeginEndFrameIf 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 
)
inherited

Manual rendering method for rendering a single object.

Parameters
rendThe renderable to issue to the pipeline
passThe pass to use
vpPointer to the viewport to render to, or 0 to use the existing viewport
doBeginEndFrameIf true, beginFrame() and endFrame() are called, otherwise not. You should leave this as false if you are calling this within the main render loop.
viewMatrixThe transform to apply from world to view space
projMatrixThe transform to apply from view to screen space
lightScissoringClippingIf true, passes that have the getLightScissorEnabled and/or getLightClipPlanesEnabled flags will cause calculation and setting of scissor rectangle and user clip planes.
doLightIterationIf true, this method will issue the renderable to the pipeline possibly multiple times, if the pass indicates it should be done once per light
manualLightListOnly 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  )
inherited

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)
inherited

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

◆ removeRenderQueueListener()

void Ogre::SceneManager::removeRenderQueueListener ( RenderQueueListener delListener)
inherited

Removes a listener previously added with addRenderQueueListener.

◆ addRenderObjectListener()

void Ogre::SceneManager::addRenderObjectListener ( RenderObjectListener newListener)
inherited

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

◆ removeRenderObjectListener()

void Ogre::SceneManager::removeRenderObjectListener ( RenderObjectListener delListener)
inherited

Removes a listener previously added with addRenderObjectListener.

◆ addSpecialCaseRenderQueue()

void Ogre::SceneManager::addSpecialCaseRenderQueue ( uint8  qid)
inherited

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
qidThe 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)
inherited

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

See also
SceneManager::addSpecialCaseRenderQueue
Parameters
qidThe 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  )
inherited

Clears the 'special case' render queue list.

See also
SceneManager::addSpecialCaseRenderQueue

◆ setSpecialCaseRenderQueueMode()

void Ogre::SceneManager::setSpecialCaseRenderQueueMode ( SpecialCaseRenderQueueMode  mode)
inherited

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

See also

Parameters
modeThe mode of processing

◆ getSpecialCaseRenderQueueMode()

SpecialCaseRenderQueueMode Ogre::SceneManager::getSpecialCaseRenderQueueMode ( void  )
inherited

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

◆ isRenderQueueToBeProcessed()

bool Ogre::SceneManager::isRenderQueueToBeProcessed ( uint8  qid)
inherited

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
qidThe 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)
inherited

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  )
inherited

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.

◆ showBoundingBoxes()

void Ogre::SceneManager::showBoundingBoxes ( bool  bShow)
inherited

Allows all bounding boxes of scene nodes to be displayed.

◆ getShowBoundingBoxes()

bool Ogre::SceneManager::getShowBoundingBoxes ( ) const
inherited

bool  autoTrack 
)
inherited

Internal method for notifying the manager that a SceneNode is autotracking.

◆ destroyQuery()

void Ogre::SceneManager::destroyQuery ( SceneQuery query)
inherited

Destroys a scene query of any type.

const AnimationStateMap& Ogre::SceneManager::getAnimationStates ( )
inlineinherited

Returns a specialised Map over all animation states in the scene.

References Ogre::AnimationStateSet::getAnimationStates().

◆ setShadowTechnique()

void Ogre::SceneManager::setShadowTechnique ( ShadowTechnique  technique)
inherited

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
techniqueThe shadowing technique to use for the scene.

◆ getShadowTechnique()

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

Gets the current shadow technique.

◆ setShowDebugShadows()

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

Enables / disables the rendering of debug information for shadows.

◆ getShowDebugShadows()

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

Are debug shadows shown?

◆ setShadowColour()

void Ogre::SceneManager::setShadowColour ( const ColourValue colour)
inherited

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
inherited

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)
inherited

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
inherited

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

◆ setShadowFarDistance()

void Ogre::SceneManager::setShadowFarDistance ( Real  distance)
inherited

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
inlineinherited

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

◆ getShadowFarDistanceSquared()

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

◆ setShadowIndexBufferSize()

void Ogre::SceneManager::setShadowIndexBufferSize ( size_t  size)
inherited

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

◆ getShadowIndexBufferSize()

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

Get the size of the shadow index buffer.

◆ setShadowTextureSize()

void Ogre::SceneManager::setShadowTextureSize ( unsigned short  size)
inherited

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

◆ setShadowTextureConfig() [2/2]

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

Set the detailed configuration for a shadow texture.

Parameters

ConstShadowTextureConfigIterator Ogre::SceneManager::getShadowTextureConfigIterator ( ) const
inherited

Get an iterator over the current shadow texture settings.

◆ setShadowTexturePixelFormat()

void Ogre::SceneManager::setShadowTexturePixelFormat ( PixelFormat  fmt)
inherited

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)
inherited

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)
inherited

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
inlineinherited

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

◆ setShadowTextureCountPerLightType()

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

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
inlineinherited

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 
)
inherited

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)
inherited

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)
inlineinherited

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
inlineinherited

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)
inlineinherited

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)
inlineinherited

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)
inherited

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
selfShadowWhether to attempt self-shadowing with texture shadows

◆ getShadowTextureSelfShadow()

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

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

◆ setShadowTextureCasterMaterial() [1/2]

void Ogre::SceneManager::setShadowTextureCasterMaterial ( const MaterialPtr mat)
inherited

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)
inherited

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)
inherited

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)
inherited

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)
inlineinherited

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
inlineinherited

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

◆ setShadowCameraSetup()

◆ setShadowUseInfiniteFarPlane()

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

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.

void Ogre::SceneManager::injectMovableObject ( MovableObject m)
inherited

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 
)
inherited

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]

◆ setNormaliseNormalsOnScale()

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

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
inlineinherited

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

◆ setFlipCullingOnNegativeScale()

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

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
inlineinherited

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

◆ _suppressRenderStateChanges()

void Ogre::SceneManager::_suppressRenderStateChanges ( bool  suppress)
inherited

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
suppressIf 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
inlineinherited

bool  shadowDerivation = true 
)
inherited

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

Parameters
passThe Pass details to set.
evenIfSuppressedSets 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.
shadowDerivationIf 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)
inherited

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.

◆ _suppressShadows()

void Ogre::SceneManager::_suppressShadows ( bool  suppress)
inherited

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

◆ _areShadowsSuppressed()

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

Are shadows suppressed?

See also
_suppressShadows

◆ _renderQueueGroupObjects()

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

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)
inherited

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

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

◆ getQueuedRenderableVisitor()

SceneMgrQueuedRenderableVisitor* Ogre::SceneManager::getQueuedRenderableVisitor ( void  ) const
inherited

Gets the current visitor object which processes queued renderables.

◆ getDestinationRenderSystem()

RenderSystem* Ogre::SceneManager::getDestinationRenderSystem ( )
inherited

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

◆ getCurrentViewport()

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

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

◆ getVisibleObjectsBoundsInfo()

const VisibleObjectsBoundsInfo& Ogre::SceneManager::getVisibleObjectsBoundsInfo ( const Camera cam) const
inherited

Returns a visibility boundary box for a specific camera.

◆ getShadowCasterBoundsInfo()

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

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

◆ setCameraRelativeRendering()

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

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
inlineinherited

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)
inherited

Add a level of detail listener.

◆ removeLodListener()

void Ogre::SceneManager::removeLodListener ( LodListener listener)
inherited

Remove a level of detail listener.

Remarks
Do not call from inside an LodListener callback method.

◆ _notifyMovableObjectLodChanged()

void Ogre::SceneManager::_notifyMovableObjectLodChanged ( MovableObjectLodChangedEvent evt)
inherited

Notify that a movable object LOD change event has occurred.

◆ _notifyEntityMeshLodChanged()

void Ogre::SceneManager::_notifyEntityMeshLodChanged ( EntityMeshLodChangedEvent evt)
inherited

Notify that an entity mesh LOD change event has occurred.

◆ _notifyEntityMaterialLodChanged()

void Ogre::SceneManager::_notifyEntityMaterialLodChanged ( EntityMaterialLodChangedEvent evt)
inherited

Notify that an entity material LOD change event has occurred.

◆ _handleLodEvents()

void Ogre::SceneManager::_handleLodEvents ( )
inherited

Handle LOD events.

◆ _getCurrentRenderStage()

IlluminationRenderStage Ogre::SceneManager::_getCurrentRenderStage ( )
inlineinherited
