Detailed Description

Instancing implementation using vertex texture through Vertex Texture Fetch (VTF) This implementation has the following advantages: Supports huge amount of instances per batch Supports skinning even with huge ammounts of instances per batch Doesn't need shader constants registers.

Best suited for skinned entities

But beware the disadvantages: VTF is only fast on modern GPUs (ATI Radeon HD 2000+, GeForce 8+ series onwards) On GeForce 6/7 series VTF is too slow VTF isn't (controversely) supported on old ATI X1800 hardware Only one bone weight per vertex is supported GPUs with low memory bandwidth (i.e. laptops and integrated GPUs) may perform even worse than no instancing

Whether this performs great or bad depends on the hardware. It improved up to 4x performance on a Intel Core 2 Quad Core X9650 GeForce 8600 GTS, and in an Intel Core 2 Duo P7350 ATI Mobility Radeon HD 4650, but went 0.75x slower on an AthlonX2 5000+ integrated nForce 6150 SE Each BaseInstanceBatchVTF has it's own texture, which occupies memory in VRAM. Approx VRAM usage can be computed by doing 12 bytes * 3 * numInstances * numBones Use flag IM_VTFBESTFIT to avoid wasting VRAM (but may reduce amount of instances per batch).

: The material requires at least a texture unit stage named "InstancingVTF"

Member Function Documentation

◆ preRender()

virtual bool Ogre::Renderable::preRender	(	SceneManager *	sm,
		RenderSystem *	rsys
	)

inlinevirtualinherited

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 in Ogre::BillboardChain.

◆ postRender()

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

inlinevirtualinherited

Called immediately after the Renderable has been rendered.

◆ 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.

See also: Renderable::setUseIdentityProjection

◆ 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.

See also: Renderable::getUseIdentityView

◆ 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. Normal renderables need not change this.

See also: Renderable::setUseIdentityView

◆ 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::SubEntity, Ogre::InstancedGeometry::GeometryBucket, and Ogre::StaticGeometry::GeometryBucket.

◆ 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

index	The 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.
value	The 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

index Index 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

index Index 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

index Index of the parameter to retrieve.

See also: setCustomParameter for full details.

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

◆ _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

constantEntry	The auto constant entry referring to the parameter being updated
params	The parameters object which this method should call to set the updated parameters.

Reimplemented in Ogre::SubEntity.

References Ogre::GpuProgramParameters::_writeRawConstant(), Ogre::GpuProgramParameters::AutoConstantEntry::data, Ogre::GpuProgramParameters::AutoConstantEntry::elementCount, and Ogre::GpuProgramParameters::AutoConstantEntry::physicalIndex.

◆ setPolygonModeOverrideable()

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

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`
	)

virtualinherited

Internal method called to notify the object that it has been attached to a node.

Reimplemented in Ogre::Entity, Ogre::ParticleSystem, Ogre::Light, Ogre::PortalBase, and Ogre::InstancedEntity.

Referenced by Ogre::PortalBase::_notifyAttached().

◆ isAttached()

bool Ogre::MovableObject::isAttached ( void ) const

inlineinherited

Returns true if this object is attached to a SceneNode or TagPoint.

◆ detachFromParent()

void Ogre::MovableObject::detachFromParent ( void )

inherited

Detaches an object from a parent SceneNode or TagPoint, if attached.

◆ isInScene()

virtual bool Ogre::MovableObject::isInScene ( void ) const

virtualinherited

Returns true if this object is attached to a SceneNode or TagPoint, and this SceneNode / TagPoint is currently in an active part of the scene graph.

Reimplemented in Ogre::InstancedEntity.

◆ _notifyMoved()

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.

◆ getWorldBoundingBox()

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

virtualinherited

Retrieves the axis-aligned bounding box for this object in world coordinates.

Implements Ogre::ShadowCaster.

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

◆ getWorldBoundingSphere()

virtual const Sphere& Ogre::MovableObject::getWorldBoundingSphere ( 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.

◆ isVisible()

virtual bool Ogre::MovableObject::isVisible ( void ) const

virtualinherited

Returns whether or not this object is supposed to be visible or not.

Remarks: Takes into account both upper rendering distance and visible flag.

Reimplemented in Ogre::InstancedGeometry::BatchInstance, and Ogre::StaticGeometry::Region.

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

dist	Distance 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

pixelSize Number 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.

◆ 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

queueID Enumerated 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

queueID	Enumerated value of the queue group to use. See the enum RenderQueueGroupID for what kind of values can be used here.
priority	The priority within a group to use.

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

◆ getRenderQueueGroup()

uint8 Ogre::MovableObject::getRenderQueueGroup ( void ) const

inlineinherited

Gets the queue group for this entity.

See also: setRenderQueueGroup

◆ _getParentNodeFullTransform()

virtual const Matrix4& 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

virtualinherited

Overridden member from ShadowCaster.

Implements Ogre::ShadowCaster.

◆ getDarkCapBounds()

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

virtualinherited

Overridden member from ShadowCaster.

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

Returns whether the Material of any Renderable that this MovableObject will add to the render queue will receive shadows.

◆ 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

vertexBuffer	The vertex buffer containing ONLY xyz position values, which must be originalVertexCount * 2 * 3 floats long.
originalVertexCount	The 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.
lightPos	4D light position in object space, when w=0.0f this represents a directional light.
extrudeDist	The 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.
