Detailed Description

Subclass of BillboardChain which automatically leaves a trail behind one or more Node instances.

Remarks
An instance of this class will watch one or more Node instances, and automatically generate a trail behind them as they move. Because this class can monitor multiple modes, it generates its own geometry in world space and thus, even though it has to be attached to a SceneNode to be visible, changing the position of the scene node it is attached to makes no difference to the geometry rendered.
The 'head' element grows smoothly in size until it reaches the required size, then a new element is added. If the segment is full, the tail element shrinks by the same proportion as the head grows before disappearing.
Elements can be faded out on a time basis, either by altering their colour or altering their alpha. The width can also alter over time.
'v' texture coordinates are fixed at 0.0 if used, meaning that you can use a 1D texture to 'smear' a colour pattern along the ribbon if you wish. The 'u' coordinates are by default (0.0, 1.0), but you can alter this using setOtherTexCoordRange if you wish.

virtual size_t Ogre::BillboardChain::getNumChainElements ( size_t  chainIndex) const
virtualinherited

Returns the number of chain elements.

◆ clearAllChains()

virtual void Ogre::BillboardChain::clearAllChains ( void  )
virtualinherited

Remove all elements from all chains (but leave the chains themselves intact).

◆ setFaceCamera()

void Ogre::BillboardChain::setFaceCamera ( bool  faceCamera,
const Vector3 normalVector = Vector3::UNIT_X 
)
inherited

Sets whether the billboard should always be facing the camera or a custom direction set by each point element.

Remarks
Billboards facing the camera are useful for smoke trails, light beams, etc by simulating a cylinder. However, because of this property, wide trails can cause several artefacts unless the head is properly covered. Therefore, non-camera-facing billboards are much more convenient for leaving big trails of movement from thin objects, for example a sword swing as seen in many fighting games.
Parameters
faceCameraTrue to be always facing the camera (Default value: True)
normalVectorOnly used when faceCamera == false. Must be a non-zero vector. This vector is the "point of reference" for each point orientation. For example, if normalVector is Vector3::UNIT_Z, and the point's orientation is an identity matrix, the segment corresponding to that point will be facing towards UNIT_Z This vector is internally normalized.

◆ getMaterialName()

virtual const String& Ogre::BillboardChain::getMaterialName ( void  ) const
inlinevirtualinherited

Get the material name in use.

References Ogre::ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME.

◆ setMaterialName()

virtual void Ogre::BillboardChain::setMaterialName ( const String name,
const String groupName = ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME 
)
virtualinherited

Set the material name to use for rendering.

◆ getSquaredViewDepth()

Real Ogre::BillboardChain::getSquaredViewDepth ( const Camera cam) const
virtualinherited

Returns the camera-relative squared depth of this renderable.

Remarks
Used to sort transparent objects. Squared depth is used rather than actual depth to avoid having to perform a square root on the result.

Implements Ogre::Renderable.

◆ getBoundingRadius()

Real Ogre::BillboardChain::getBoundingRadius ( void  ) const
virtualinherited

Retrieves the radius of the origin-centered bounding sphere for this object.

Implements Ogre::MovableObject.

◆ getBoundingBox()

const AxisAlignedBox& Ogre::BillboardChain::getBoundingBox ( void  ) const
virtualinherited

Remarks
This bounding box is in local coordinates.

Implements Ogre::MovableObject.

◆ getMaterial()

const MaterialPtr& Ogre::BillboardChain::getMaterial ( void  ) const
virtualinherited

Retrieves a weak reference to the material this renderable object uses.

Remarks
Note that the Renderable also has the option to override the getTechnique method to specify a particular Technique to use instead of the best one available.

Implements Ogre::Renderable.

◆ _updateRenderQueue()

void Ogre::BillboardChain::_updateRenderQueue ( RenderQueue queue)
virtualinherited

Internal method by which the movable object must add Renderable subclass instances to the rendering queue.

Remarks
The engine will call this method when this object is to be rendered. The object must then create one or more Renderable subclass instances which it places on the passed in Queue for rendering.

Implements Ogre::MovableObject.

◆ getRenderOperation()

void Ogre::BillboardChain::getRenderOperation ( RenderOperation op)
virtualinherited

Gets the render operation required to send this object to the frame buffer.

Implements Ogre::Renderable.

◆ preRender()

virtual bool Ogre::BillboardChain::preRender ( SceneManager sm,
RenderSystem rsys 
)
virtualinherited

Called just prior to the Renderable being rendered.

Remarks
OGRE is a queued renderer, so the actual render commands are executed at a later time than the point at which an object is discovered to be visible. This allows ordering & grouping of renders without the discovery process having to be aware of it. It also means OGRE uses declarative render information rather than immediate mode rendering - this is very useful in that certain effects and processes can automatically be applied to a wide range of scenes, but the downside is that special cases are more difficult to handle, because there is not the declared state to cope with it.
This method allows a Renderable to do something special at the actual point of rendering if it wishes to. When this method is called, all the material render state as declared by this Renderable has already been set, all that is left to do is to bind the buffers and perform the render. The Renderable may modify render state itself if it wants to (and restore it in the postRender call) before the automated render happens, or by returning 'false' from this method can actually suppress the automatic render and perform one of its own.
Returns
true if the automatic render should proceed, false to skip it on the assumption that the Renderable has done it manually.

Reimplemented from Ogre::Renderable.

◆ getWorldTransforms()

void Ogre::BillboardChain::getWorldTransforms ( Matrix4 xform) const
virtualinherited

Gets the world transform matrix / matrices for this renderable object.

Remarks
If the object has any derived transforms, these are expected to be up to date as long as all the SceneNode structures have been updated before this is called.
This method will populate transform with 1 matrix if it does not use vertex blending. If it does use vertex blending it will fill the passed in pointer with an array of matrices, the length being the value returned from getNumWorldTransforms.
Note
Internal Ogre never supports non-affine matrix for world transform matrix/matrices, the behavior is undefined if returns non-affine matrix here.

Implements Ogre::Renderable.

◆ getLights()

const LightList& Ogre::BillboardChain::getLights ( void  ) const
virtualinherited

Gets a list of lights, ordered relative to how close they are to this renderable.

Remarks
Directional lights, which have no position, will always be first on this list.

Implements Ogre::Renderable.

◆ visitRenderables()

void Ogre::BillboardChain::visitRenderables ( Renderable::Visitor visitor,
bool  debugRenderables = false 
)
virtualinherited

Method to allow a caller to abstractly iterate over the Renderable instances that this MovableObject will add to the render queue when asked, if any.

Parameters
visitorPointer to a class implementing the Renderable::Visitor interface which will be called back for each Renderable which will be queued. Bear in mind that the state of the Renderable instances may not be finalised depending on when you call this.
debugRenderablesIf false, only regular renderables will be visited (those for normal display). If true, debug renderables will be included too.

◆ getParentNode()

Node* Ogre::MovableObject::getParentNode ( void  ) const
inlineinherited

Returns the node to which this object is attached.

Remarks
A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. Both are Node subclasses so this method will return either.

◆ getParentSceneNode()

SceneNode* Ogre::MovableObject::getParentSceneNode ( void  ) const
inherited

Returns the scene node to which this object is attached.

Remarks
A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. This method will return the scene node of the parent entity if the latter is true.

◆ isParentTagPoint()

bool Ogre::MovableObject::isParentTagPoint ( ) const
inlineinherited

Gets whether the parent node is a TagPoint (or a SceneNode)

◆ _notifyAttached()

virtual void Ogre::MovableObject::_notifyAttached ( Node parent,
bool  isTagPoint = false

virtual void Ogre::MovableObject::_notifyMoved ( void  )
virtualinherited

Internal method called to notify the object that it has been moved.

Reimplemented in Ogre::Light, Ogre::PortalBase, Ogre::InstancedEntity, and Ogre::PCZLight.

◆ _notifyCurrentCamera()

virtual void Ogre::MovableObject::_notifyCurrentCamera ( Camera cam)
virtualinherited

Internal method to notify the object of the camera to be used for the next rendering operation.

Remarks
Certain objects may want to do specific processing based on the camera position. This method notifies them in case they wish to do this.

Reimplemented in Ogre::BillboardSet, Ogre::Frustum, Ogre::StaticGeometry::Region, Ogre::Entity, Ogre::ParticleSystem, Ogre::InstanceBatch, Ogre::SimpleRenderable, and Ogre::MovablePlane.

◆ getWorldBoundingBox()

virtual const AxisAlignedBox& Ogre::MovableObject::getWorldBoundingBox ( bool  derive = false) const

virtualinherited

Retrieves the worldspace bounding sphere for this object.

Reimplemented in Ogre::Entity, and Ogre::PortalBase.

◆ setVisible()

void Ogre::MovableObject::setVisible ( bool  visible)
inlineinherited

Tells this object whether to be visible or not, if it has a renderable component.

Note
An alternative approach of making an object invisible is to detach it from it's SceneNode, or to remove the SceneNode entirely. Detaching a node means that structurally the scene graph changes. Once this change has taken place, the objects / nodes that have been removed have less overhead to the visibility detection pass than simply making the object invisible, so if you do this and leave the objects out of the tree for a long time, it's faster. However, the act of detaching / reattaching nodes is in itself more expensive than setting an object visibility flag, since in the latter case structural changes are not made. Therefore, small or frequent visibility changes are best done using this method; large or more longer term changes are best done by detaching.

Referenced by Ogre::Light::setVisible().

◆ getVisible()

bool Ogre::MovableObject::getVisible ( void  ) const
inlineinherited

Gets this object whether to be visible or not, if it has a renderable component.

Remarks
Returns the value set by MovableObject::setVisible only.

Referenced by Ogre::Frustum::isCustomProjectionMatrixEnabled().

◆ setRenderingDistance()

void Ogre::MovableObject::setRenderingDistance ( Real  dist)
inlineinherited

Sets the distance at which the object is no longer rendered.

Note
Camera::setUseRenderingDistance() needs to be called for this parameter to be used.
Parameters
distDistance beyond which the object will not be rendered (the default is 0, which means objects are always rendered).

◆ getRenderingDistance()

Real Ogre::MovableObject::getRenderingDistance ( void  ) const
inlineinherited

Gets the distance at which batches are no longer rendered.

◆ setRenderingMinPixelSize()

void Ogre::MovableObject::setRenderingMinPixelSize ( Real  pixelSize)
inlineinherited

Sets the minimum pixel size an object needs to be in both screen axes in order to be rendered.

Note
Camera::setUseMinPixelSize() needs to be called for this parameter to be used.
Parameters
pixelSizeNumber of minimum pixels (the default is 0, which means objects are always rendered).

◆ getRenderingMinPixelSize()

Real Ogre::MovableObject::getRenderingMinPixelSize ( ) const
inlineinherited

Returns the minimum pixel size an object needs to be in both screen axes in order to be rendered.

◆ setUserAny() [1/2]

void Ogre::MovableObject::setUserAny ( const Any anything)
inlineinherited
Deprecated:
use UserObjectBindings::setUserAny via getUserObjectBindings() instead.

Sets any kind of user value on this object.

Remarks
This method allows you to associate any user value you like with this MovableObject. This can be a pointer back to one of your own classes for instance.

◆ setUserAny() [2/2]

void Ogre::Renderable::setUserAny ( const Any anything)
inlineinherited
Deprecated:
use UserObjectBindings::setUserAny via getUserObjectBindings() instead.

Sets any kind of user value on this object.

Remarks
This method allows you to associate any user value you like with this Renderable. This can be a pointer back to one of your own classes for instance.

Referenced by Ogre::InstanceBatch::getRenderOperation().

◆ getUserAny() [1/2]

const Any& Ogre::MovableObject::getUserAny ( void  ) const
inlineinherited
Deprecated:
use UserObjectBindings::getUserAny via getUserObjectBindings() instead.

Retrieves the custom user value associated with this object.

◆ getUserAny() [2/2]

const Any& Ogre::Renderable::getUserAny ( void  ) const
inlineinherited
Deprecated:
use UserObjectBindings::getUserAny via getUserObjectBindings() instead.

Retrieves the custom user value associated with this object.

Referenced by Ogre::InstanceBatch::getRenderOperation().

◆ getUserObjectBindings() [1/4]

UserObjectBindings& Ogre::MovableObject::getUserObjectBindings ( )
inlineinherited

Return an instance of user objects binding associated with this class.

You can use it to associate one or more custom objects with this class instance.

See also

See also
UserObjectBindings::setUserAny.

◆ setRenderQueueGroup()

virtual void Ogre::MovableObject::setRenderQueueGroup ( uint8  queueID)
virtualinherited

Sets the render queue group this entity will be rendered through.

Remarks
Render queues are grouped to allow you to more tightly control the ordering of rendered objects. If you do not call this method, all Entity objects default to the default queue (RenderQueue::getDefaultQueueGroup), which is fine for most objects. You may want to alter this if you want this entity to always appear in front of other objects, e.g. for a 3D menu system or such.
See RenderQueue for more details.
Parameters
queueIDEnumerated value of the queue group to use. See the enum RenderQueueGroupID for what kind of values can be used here.

Reimplemented in Ogre::ParticleSystem, and Ogre::Entity.

◆ setRenderQueueGroupAndPriority()

virtual void Ogre::MovableObject::setRenderQueueGroupAndPriority ( uint8  queueID,
ushort  priority 
)
virtualinherited

Sets the render queue group and group priority this entity will be rendered through.

Remarks
Render queues are grouped to allow you to more tightly control the ordering of rendered objects. Within a single render group there another type of grouping called priority which allows further control. If you do not call this method, all Entity objects default to the default queue and priority (RenderQueue::getDefaultQueueGroup, RenderQueue::getDefaultRenderablePriority), which is fine for most objects. You may want to alter this if you want this entity to always appear in front of other objects, e.g. for a 3D menu system or such.
See RenderQueue for more details.
Parameters
queueIDEnumerated value of the queue group to use. See the enum RenderQueueGroupID for what kind of values can be used here.
priorityThe priority within a group to use.

Reimplemented in Ogre::ParticleSystem, and Ogre::Entity.

◆ getRenderQueueGroup()

◆ _getParentNodeFullTransform()

virtual const Affine3& Ogre::MovableObject::_getParentNodeFullTransform ( void  ) const
virtualinherited

Return the full transformation of the parent sceneNode or the attachingPoint node.

Reimplemented in Ogre::InstancedEntity.

◆ setQueryFlags()

void Ogre::MovableObject::setQueryFlags ( uint32  flags)
inlineinherited

Sets the query flags for this object.

Remarks
When performing a scene query, this object will be included or excluded according to flags on the object and flags on the query. This is a bitwise value, so only when a bit on these flags is set, will it be included in a query asking for that flag. The meaning of the bits is application-specific.

◆ addQueryFlags()

void Ogre::MovableObject::addQueryFlags ( uint32  flags)
inlineinherited

As setQueryFlags, except the flags passed as parameters are appended to the existing flags on this object.

◆ removeQueryFlags()

void Ogre::MovableObject::removeQueryFlags ( uint32  flags)
inlineinherited

As setQueryFlags, except the flags passed as parameters are removed from the existing flags on this object.

◆ getQueryFlags()

uint32 Ogre::MovableObject::getQueryFlags ( void  ) const
inlineinherited

Returns the query flags relevant for this object.

◆ setDefaultQueryFlags()

static void Ogre::MovableObject::setDefaultQueryFlags ( uint32  flags)
inlinestaticinherited

Set the default query flags for all future MovableObject instances.

◆ getDefaultQueryFlags()

static uint32 Ogre::MovableObject::getDefaultQueryFlags ( )
inlinestaticinherited

Get the default query flags for all future MovableObject instances.

◆ setVisibilityFlags()

void Ogre::MovableObject::setVisibilityFlags ( uint32  flags)
inlineinherited

Sets the visibility flags for this object.

Remarks
As well as a simple true/false value for visibility (as seen in setVisible), you can also set visibility flags which when 'and'ed with the SceneManager's visibility mask can also make an object invisible.

◆ addVisibilityFlags()

void Ogre::MovableObject::addVisibilityFlags ( uint32  flags)
inlineinherited

As setVisibilityFlags, except the flags passed as parameters are appended to the existing flags on this object.

◆ removeVisibilityFlags()

void Ogre::MovableObject::removeVisibilityFlags ( uint32  flags)
inlineinherited

As setVisibilityFlags, except the flags passed as parameters are removed from the existing flags on this object.

◆ getVisibilityFlags()

uint32 Ogre::MovableObject::getVisibilityFlags ( void  ) const
inlineinherited

Returns the visibility flags relevant for this object.

◆ setDefaultVisibilityFlags()

static void Ogre::MovableObject::setDefaultVisibilityFlags ( uint32  flags)
inlinestaticinherited

Set the default visibility flags for all future MovableObject instances.

◆ getDefaultVisibilityFlags()

static uint32 Ogre::MovableObject::getDefaultVisibilityFlags ( )
inlinestaticinherited

Get the default visibility flags for all future MovableObject instances.

◆ setListener()

void Ogre::MovableObject::setListener ( Listener listener)
inlineinherited

Sets a listener for this object.

Remarks
Note for size and performance reasons only one listener per object is allowed.

◆ getListener()

Listener* Ogre::MovableObject::getListener ( void  ) const
inlineinherited

Gets the current listener for this object.

◆ queryLights()

const LightList& Ogre::MovableObject::queryLights ( void  ) const
inherited

Gets a list of lights, ordered relative to how close they are to this movable object.

Remarks
By default, this method gives the listener a chance to populate light list first, if there is no listener or Listener::objectQueryLights returns NULL, it'll query the light list from parent entity if it is present, or returns SceneNode::findLights if it has parent scene node, otherwise it just returns an empty list.
The object internally caches the light list, so it will recalculate it only when object is moved, or lights that affect the frustum have been changed (
See also
SceneManager::_getLightsDirtyCounter), but if listener exists, it will be called each time, so the listener should implement their own cache mechanism to optimise performance.
This method can be useful when implementing Renderable::getLights in case the renderable is a part of the movable.
Returns
The list of lights use to lighting this object.

◆ getLightMask()

uint32 Ogre::MovableObject::getLightMask ( ) const
inlineinherited

Get a bitwise mask which will filter the lights affecting this object.

Remarks
By default, this mask is fully set meaning all lights will affect this object

◆ setLightMask()

void Ogre::MovableObject::setLightMask ( uint32  lightMask)
inherited

Set a bitwise mask which will filter the lights affecting this object.

Remarks
This mask will be compared against the mask held against Light to determine if a light should affect a given object. By default, this mask is fully set meaning all lights will affect this object

◆ _getLightList()

LightList* Ogre::MovableObject::_getLightList ( )
inlineinherited

Returns a pointer to the current list of lights for this object.

Remarks
You should not modify this list outside of MovableObject::Listener::objectQueryLights (say if you want to use it to implement this method, and use the pointer as a return value) and for reading it's only accurate as at the last frame.

◆ getEdgeList()

EdgeData* Ogre::MovableObject::getEdgeList ( void  )
inlinevirtualinherited

Returns details of the edges which might be used to determine a silhouette.

Implements Ogre::ShadowCaster.

Reimplemented in Ogre::StaticGeometry::Region.

◆ hasEdgeList()

bool Ogre::MovableObject::hasEdgeList ( void  )
inlinevirtualinherited

Returns whether the object has a valid edge list.

Implements Ogre::ShadowCaster.

Reimplemented in Ogre::StaticGeometry::Region.

◆ getShadowVolumeRenderableIterator()

ShadowRenderableListIterator Ogre::MovableObject::getShadowVolumeRenderableIterator ( ShadowTechnique  shadowTechnique,
const Light light,
HardwareIndexBufferSharedPtr indexBuffer,
size_t *  indexBufferUsedSize,
bool  extrudeVertices,
Real  extrusionDist,
unsigned long  flags = 0 
)
virtualinherited

Define a default implementation of method from ShadowCaster which implements no shadows.

Implements Ogre::ShadowCaster.

Reimplemented in Ogre::StaticGeometry::Region.

◆ getLightCapBounds()

const AxisAlignedBox& Ogre::MovableObject::getLightCapBounds ( void  ) const
overridevirtualinherited

Gets the world space bounding box of the light cap.

◆ getDarkCapBounds()

const AxisAlignedBox& Ogre::MovableObject::getDarkCapBounds ( const Light light,
Real  dirLightExtrusionDist 
) const
overridevirtualinherited

Gets the world space bounding box of the dark cap, as extruded using the light provided.

Implements Ogre::ShadowCaster.

◆ setCastShadows()

void Ogre::MovableObject::setCastShadows ( bool  enabled)
inlineinherited

Sets whether or not this object will cast shadows.

Remarks
This setting simply allows you to turn on/off shadows for a given object. An object will not cast shadows unless the scene supports it in any case (see SceneManager::setShadowTechnique), and also the material which is in use must also have shadow casting enabled. By default all entities cast shadows. If, however, for some reason you wish to disable this for a single object then you can do so using this method.
Note
This method normally refers to objects which block the light, but since Light is also a subclass of MovableObject, in that context it means whether the light causes shadows itself.

◆ getCastShadows()

bool Ogre::MovableObject::getCastShadows ( void  ) const
inlinevirtualinherited

Returns whether shadow casting is enabled for this object.

Implements Ogre::ShadowCaster.

◆ getReceivesShadows()

bool Ogre::MovableObject::getReceivesShadows ( )
inherited

◆ getPointExtrusionDistance()

Real Ogre::MovableObject::getPointExtrusionDistance ( const Light l) const
virtualinherited

Get the distance to extrude for a point/spot light.

Implements Ogre::ShadowCaster.

◆ getTypeFlags()

virtual uint32 Ogre::MovableObject::getTypeFlags ( void  ) const
virtualinherited

Get the 'type flags' for this MovableObject.

Remarks
A type flag identifies the type of the MovableObject as a bitpattern. This is used for categorical inclusion / exclusion in SceneQuery objects. By default, this method returns all ones for objects not created by a MovableObjectFactory (hence always including them); otherwise it returns the value assigned to the MovableObjectFactory. Custom objects which don't use MovableObjectFactory will need to override this if they want to be included in queries.

Reimplemented in Ogre::BillboardSet, Ogre::Entity, Ogre::ParticleSystem, Ogre::Frustum, Ogre::StaticGeometry::Region, and Ogre::Light.

◆ setDebugDisplayEnabled()

void Ogre::MovableObject::setDebugDisplayEnabled ( bool  enabled)
inlineinherited

Sets whether or not the debug display of this object is enabled.

Remarks
Some objects aren't visible themselves but it can be useful to display a debug representation of them. Or, objects may have an additional debug display on top of their regular display. This option enables / disables that debug display. Objects that are not visible never display debug geometry regardless of this setting.

◆ isDebugDisplayEnabled()

bool Ogre::MovableObject::isDebugDisplayEnabled ( void  ) const
inlineinherited

Gets whether debug display of this object is enabled.

◆ clearShadowRenderableList()

static void Ogre::ShadowCaster::clearShadowRenderableList ( ShadowRenderableList shadowRenderables)
staticinherited

Common implementation of releasing shadow renderables.

◆ extrudeVertices()

static void Ogre::ShadowCaster::extrudeVertices ( const HardwareVertexBufferSharedPtr vertexBuffer,
size_t  originalVertexCount,
const Vector4 lightPos,
Real  extrudeDist 
)
staticinherited

Utility method for extruding vertices based on a light.

Remarks
Unfortunately, because D3D cannot handle homogeneous (4D) position coordinates in the fixed-function pipeline (GL can, but we have to be cross-API), when we extrude in software we cannot extrude to infinity the way we do in the vertex program (by setting w to 0.0f). Therefore we extrude by a fixed distance, which may cause some problems with larger scenes. Luckily better hardware (ie vertex programs) can fix this.
Parameters
vertexBufferThe vertex buffer containing ONLY xyz position values, which must be originalVertexCount * 2 * 3 floats long.
originalVertexCountThe count of the original number of vertices, i.e. the number in the mesh, not counting the doubling which has already been done (by VertexData::prepareForShadowVolume) to provide the extruded area of the buffer.
lightPos4D light position in object space, when w=0.0f this represents a directional light.
extrudeDistThe distance to extrude.

◆ getAnimableValueNames()

const StringVector& Ogre::AnimableObject::getAnimableValueNames ( void  ) const
inlineinherited

Gets a list of animable value names for this object.

References Ogre::Exception::ERR_ITEM_NOT_FOUND, and OGRE_EXCEPT.

◆ createAnimableValue()

virtual AnimableValuePtr Ogre::AnimableObject::createAnimableValue ( const String valueName)
inlinevirtualinherited

Create a reference-counted AnimableValuePtr for the named value.

Remarks
You can use the returned object to animate a value on this object, using AnimationTrack. Subclasses must override this if they wish to support animation of their values.

Reimplemented in Ogre::Light.

References Ogre::Exception::ERR_ITEM_NOT_FOUND, and OGRE_EXCEPT.

◆ getTechnique()

virtual Technique* Ogre::Renderable::getTechnique ( void  ) const
inlinevirtualinherited

Retrieves a pointer to the Material Technique this renderable object uses.

Remarks
This is to allow Renderables to use a chosen Technique if they wish, otherwise they will use the best Technique available for the Material they are using.

Reimplemented in Ogre::InstanceBatch, Ogre::StaticGeometry::GeometryBucket, and Ogre::SubEntity.

◆ postRender()

virtual void Ogre::Renderable::postRender ( SceneManager sm,
RenderSystem rsys 
)
inlinevirtualinherited

Called immediately after the Renderable has been rendered.

◆ getNumWorldTransforms()

virtual unsigned short Ogre::Renderable::getNumWorldTransforms ( void  ) const
inlinevirtualinherited

Returns the number of world transform matrices this renderable requires.

Remarks
When a renderable uses vertex blending, it uses multiple world matrices instead of a single one. Each vertex sent to the pipeline can reference one or more matrices in this list with given weights. If a renderable does not use vertex blending this method returns 1, which is the default for simplicity.

Reimplemented in Ogre::BorderRenderable, Ogre::SubEntity, Ogre::BaseInstanceBatchVTF, Ogre::InstanceBatchHW, and Ogre::InstanceBatchShader.

◆ setUseIdentityProjection()

void Ogre::Renderable::setUseIdentityProjection ( bool  useIdentityProjection)
inlineinherited

Sets whether or not to use an 'identity' projection.

Remarks
Usually Renderable objects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normal renderables need not change this. The default is false.
See also
Renderable::getUseIdentityProjection

◆ getUseIdentityProjection()

bool Ogre::Renderable::getUseIdentityProjection ( void  ) const
inlineinherited

Returns whether or not to use an 'identity' projection.

Remarks
Usually Renderable objects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normal renderables need not change this.

◆ setUseIdentityView()

void Ogre::Renderable::setUseIdentityView ( bool  useIdentityView)
inlineinherited

Sets whether or not to use an 'identity' view.

Remarks
Usually Renderable objects will use a view matrix as determined by the active camera. However, if they want they can cancel this out and use an identity matrix, which means all geometry is assumed to be relative to camera space already. Useful for overlay rendering. Normal renderables need not change this. The default is false.

◆ getUseIdentityView()

bool Ogre::Renderable::getUseIdentityView ( void  ) const
inlineinherited

Returns whether or not to use an 'identity' view.

Remarks
Usually Renderable objects will use a view matrix as determined by the active camera. However, if they want they can cancel this out and use an identity matrix, which means all geometry is assumed to be relative to camera space already. Useful for overlay rendering.

◆ getCastsShadows()

virtual bool Ogre::Renderable::getCastsShadows ( void  ) const
inlinevirtualinherited

Method which reports whether this renderable would normally cast a shadow.

Remarks
Subclasses should override this if they could have been used to generate a shadow.

Reimplemented in Ogre::StaticGeometry::GeometryBucket, and Ogre::SubEntity.

◆ setCustomParameter()

void Ogre::Renderable::setCustomParameter ( size_t  index,
const Vector4 value 
)
inlineinherited

Sets a custom parameter for this Renderable, which may be used to drive calculations for this specific Renderable, like GPU program parameters.

Remarks
Calling this method simply associates a numeric index with a 4-dimensional value for this specific Renderable. This is most useful if the material which this Renderable uses a vertex or fragment program, and has an ACT_CUSTOM parameter entry. This parameter entry can refer to the index you specify as part of this call, thereby mapping a custom parameter for this renderable to a program parameter.
Parameters
indexThe index with which to associate the value. Note that this does not have to start at 0, and can include gaps. It also has no direct correlation with a GPU program parameter index - the mapping between the two is performed by the ACT_CUSTOM entry, if that is used.
valueThe value to associate.

◆ removeCustomParameter()

void Ogre::Renderable::removeCustomParameter ( size_t  index)
inlineinherited

Removes a custom value which is associated with this Renderable at the given index.

Parameters
indexIndex of the parameter to remove.
See also
setCustomParameter for full details.

◆ hasCustomParameter()

bool Ogre::Renderable::hasCustomParameter ( size_t  index) const
inlineinherited

Checks whether a custom value is associated with this Renderable at the given index.

Parameters
indexIndex of the parameter to check for existence.
See also
setCustomParameter for full details.

◆ getCustomParameter()

const Vector4& Ogre::Renderable::getCustomParameter ( size_t  index) const
inlineinherited

Gets the custom value associated with this Renderable at the given index.

Parameters
indexIndex of the parameter to retrieve.
See also
setCustomParameter for full details.

◆ _updateCustomGpuParameter()

virtual void Ogre::Renderable::_updateCustomGpuParameter ( const GpuProgramParameters::AutoConstantEntry constantEntry,
GpuProgramParameters params 
) const
inlinevirtualinherited

Update a custom GpuProgramParameters constant which is derived from information only this Renderable knows.

Remarks
This method allows a Renderable to map in a custom GPU program parameter based on it's own data. This is represented by a GPU auto parameter of ACT_CUSTOM, and to allow there to be more than one of these per Renderable, the 'data' field on the auto parameter will identify which parameter is being updated. The implementation of this method must identify the parameter being updated, and call a 'setConstant' method on the passed in GpuProgramParameters object, using the details provided in the incoming auto constant setting to identify the index at which to set the parameter.
You do not need to override this method if you're using the standard sets of data associated with the Renderable as provided by setCustomParameter and getCustomParameter. By default, the implementation will map from the value indexed by the 'constantEntry.data' parameter to a value previously set by setCustomParameter. But custom Renderables are free to override this if they want, in any case.
Parameters
constantEntryThe auto constant entry referring to the parameter being updated
paramsThe parameters object which this method should call to set the updated parameters.

Reimplemented in Ogre::SubEntity.

◆ setPolygonModeOverrideable()

void Ogre::Renderable::setPolygonModeOverrideable ( bool  override)
inlineinherited

Sets whether this renderable's chosen detail level can be overridden (downgraded) by the camera setting.

Parameters
overridetrue means that a lower camera detail will override this renderables detail level, false means it won't.

◆ getPolygonModeOverrideable()

bool Ogre::Renderable::getPolygonModeOverrideable ( void  ) const
inlineinherited

Gets whether this renderable's chosen detail level can be overridden (downgraded) by the camera setting.

void Ogre::Renderable::setRenderSystemData ( RenderSystemDataPtr  val) const
inlineinherited

Sets RenderSystem private data.

Remarks
This should only be used by a RenderSystem
