Detailed Description

Defines an instance of a discrete, movable object based on a Mesh.

Remarks:
Ogre generally divides renderable objects into 2 groups, discrete (separate) and relatively small objects which move around the world, and large, sprawling geometry which makes up generally immovable scenery, aka 'level geometry'.
The Mesh and SubMesh classes deal with the definition of the geometry used by discrete movable objects. Entities are actual instances of objects based on this geometry in the world. Therefore there is usually a single set Mesh for a car, but there may be multiple entities based on it in the world. Entities are able to override aspects of the Mesh it is defined by, such as changing material properties per instance (so you can have many cars using the same geometry but different textures for example). Because a Mesh is split into SubMeshes for this purpose, the Entity class is a grouping class (much like the Mesh class) and much of the detail regarding individual changes is kept in the SubEntity class. There is a 1:1 relationship between SubEntity instances and the SubMesh instances associated with the Mesh the Entity is based on.
Entity and SubEntity classes are never created directly. Use the createEntity method of the SceneManager (passing a model name) to create one.
Entities are included in the scene by associating them with a SceneNode, using the attachEntity method. See the SceneNode class for full information.
Note:
No functions were declared virtual to improve performance.

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

Reimplemented in Ogre::Light.

void Ogre::Entity::_updateAnimation ( void   ) 

Advanced method to perform all the updates required for an animated entity.

Remarks:

void Ogre::Entity::_updateRenderQueue ( RenderQueue queue  ) 

Overridden - see MovableObject.

virtual void Ogre::MovableObject::_updateRenderQueue ( RenderQueue queue  )  [pure virtual, inherited]

Definition at line 377 of file OgreMovableObject.h.

void Ogre::Entity::addSoftwareAnimationRequest ( bool  normalsAlso  ) 

Add a request for software animation.

Remarks:
Tells the entity to perform animation calculations for skeletal/vertex animations in software, regardless of the current setting of isHardwareAnimationEnabled(). Software animation will be performed any time one or more requests have been made. If 'normalsAlso' is 'true', then the entity will also do software blending on normal vectors, in addition to positions. This advanced method useful for situations in which access to actual mesh vertices is required, such as accurate collision detection or certain advanced shading techniques. When software animation is no longer needed, the caller of this method should always remove the request by calling removeSoftwareAnimationRequest(), passing the same value for 'normalsAlso'.

MovableObject pMovable,
const Quaternion offsetOrientation = Quaternion::IDENTITY,
const Vector3 offsetPosition = Vector3::ZERO 
)

Attaches another object to a certain bone of the skeleton which this entity uses.

Remarks:
This method can be used to attach another object to an animated part of this entity, by attaching it to a bone in the skeleton (with an offset if required). As this entity is animated, the attached object will move relative to the bone to which it is attached.
An exception is thrown if the movable object is already attached to the bone, another bone or scenenode. If the entity has no skeleton or the bone name cannot be found then an exception is thrown.
Parameters:
boneName The name of the bone (in the skeleton) to attach this object
pMovable Pointer to the object to attach
offsetOrientation An adjustment to the orientation of the attached object, relative to the bone.

Parameters:
newName Name for the new entity.
VertexData* Ogre::Entity::cloneVertexDataRemoveBlendInfo ( const VertexData source  )  [protected]

Internal method to clone vertex data definitions but to remove blend buffers.

Detaches an object by pointer.

Remarks:
Use this method to destroy a MovableObject which is attached to a bone of belonging this entity. But sometimes the object may be not in the child object list because it is a lod entity, this method can safely detect and ignore in this case and won't raise an exception.
void Ogre::Entity::detachObjectImpl ( MovableObject pObject  )  [protected]

internal implementation of detaching a 'child' object of this entity and clear the parent node of the child entity

virtual void Ogre::ShadowCaster::extrudeBounds ( AxisAlignedBox box,
const Vector4 lightPos,
Real  extrudeDist 
) const [protected, virtual, inherited]

Utility method for extruding a bounding box.

Parameters:
box Original bounding box, will be updated in-place
lightPos 4D light position in object space, when w=0.0f this represents a directional light
extrudeDist The distance to extrude
static void Ogre::ShadowCaster::extrudeVertices ( const HardwareVertexBufferSharedPtr vertexBuffer,
size_t  originalVertexCount,
const Vector4 lightPos,
Real  extrudeDist 
) [static, inherited]

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
const VertexData* Ogre::Entity::findBlendedVertexData ( const VertexData orig  )  [protected]

bool  extrudeVertices,
Real  extrusionDistance,
unsigned long  flags = 0 
) [pure virtual, inherited]

int Ogre::Entity::getSoftwareAnimationNormalsRequests ( void   )  const

Returns the number of requests that have been made for software animation of normals.

Remarks:
If non-zero, and getSoftwareAnimationRequests() also returns non-zero, then software animation of normals will be performed in updateAnimation regardless of the current setting of isHardwareAnimationEnabled or any internal optimise for eliminate software animation. Currently it is not possible to force software animation of only normals. Consequently this value is always less than or equal to that returned by getSoftwareAnimationRequests(). Requests for software animation of normals are made by calling the addSoftwareAnimationRequest() method with 'true' as the parameter.

Definition at line 592 of file OgreEntity.h.

int Ogre::Entity::getSoftwareAnimationRequests ( void   )  const

Returns the number of requests that have been made for software animation.

Remarks:

virtual uint32 Ogre::MovableObject::getTypeFlags ( void   )  const [virtual, inherited]

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.

virtual const Sphere& Ogre::MovableObject::getWorldBoundingSphere ( bool  derive = false  )  const [virtual, inherited]

Retrieves the worldspace bounding sphere for this object.

const Sphere& Ogre::Entity::getWorldBoundingSphere ( bool  derive = false  )  const
bool Ogre::MovableObject::hasEdgeList ( void   )  [inherited]

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

Reimplemented in Ogre::ManualObject, and Ogre::StaticGeometry::Region.

Definition at line 477 of file OgreMovableObject.h.

virtual bool Ogre::ShadowCaster::hasEdgeList ( void   )  [pure virtual, inherited]

Returns whether the object has a valid edge list.

bool Ogre::Entity::hasEdgeList ( void   ) 

Overridden member from ShadowCaster.

bool Ogre::Entity::hasSkeleton ( void   )  const

Returns whether or not this entity is skeletally animated.

Definition at line 555 of file OgreEntity.h.

bool Ogre::Entity::hasVertexAnimation ( void   )  const

Returns whether or not this entity is either morph or pose animated.

void Ogre::Entity::initHardwareAnimationElements ( VertexData vdata,
ushort  numberOfElements 
) [protected]

Initialise the hardware animation elements for given vertex data.

virtual void Ogre::AnimableObject::initialiseAnimableDictionary ( StringVector  )  const [protected, virtual, inherited]

Internal method for initialising dictionary; should be implemented by subclasses wanting to expose animable parameters.

Definition at line 286 of file OgreAnimable.h.

virtual bool Ogre::MovableObject::isAttached ( void   )  const [virtual, inherited]

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

virtual bool Ogre::MovableObject::isDebugDisplayEnabled ( void   )  const [virtual, inherited]

Gets whether debug display of this object is enabled.

Definition at line 546 of file OgreMovableObject.h.

bool Ogre::Entity::isHardwareAnimationEnabled ( void   )  const

Returns whether or not hardware animation is enabled.

Remarks:
Because fixed-function indexed vertex blending is rarely supported by existing graphics cards, hardware animation can only be done if the vertex programs in the materials used to render an entity support it. Therefore, this method will only return true if all the materials assigned to this entity have vertex programs assigned, and all those vertex programs must support 'includes_morph_animation true' if using morph animation, 'includes_pose_animation true' if using pose animation and 'includes_skeletal_animation true' if using skeletal animation.

Definition at line 569 of file OgreEntity.h.

bool Ogre::Entity::isInitialised ( void   )  const

Has this Entity been initialised yet?

Remarks:
If this returns false, it means this Entity hasn't been completely constructed yet from the underlying resources (Mesh, Skeleton), which probably means they were delay-loaded and aren't available yet. This Entity won't render until it has been successfully initialised, nor will many of the manipulation methods function.

Definition at line 740 of file OgreEntity.h.

virtual bool Ogre::MovableObject::isInScene ( void   )  const [virtual, inherited]

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.

virtual bool Ogre::MovableObject::isParentTagPoint (  )  const [virtual, inherited]

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

Definition at line 213 of file OgreMovableObject.h.

virtual bool Ogre::MovableObject::isVisible ( void   )  const [virtual, inherited]

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, Ogre::StaticGeometry::Region, and Ogre::TerrainQuadTreeNode::Movable.

virtual void Ogre::Resource::Listener::loadingComplete ( Resource  )  [virtual, inherited]

Called whenever the resource finishes loading.

Remarks:
If a Resource has been marked as background loaded (
See also:
Resource::setBackgroundLoaded), the call does not itself occur in the thread which is doing the loading; when loading is complete a response indicator is placed with the ResourceGroupManager, which will then be sent back to the listener as part of the application's primary frame loop thread.

void Ogre::Entity::prepareTempBlendBuffers ( void   )  [protected]

Internal method for preparing this Entity for use in animation.

virtual void Ogre::Resource::Listener::preparingComplete ( Resource  )  [virtual, inherited]

called whenever the resource finishes preparing (paging into memory).

Remarks:
If a Resource has been marked as background loaded (
See also:
Resource::setBackgroundLoaded) the call does not itself occur in the thread which is doing the preparing; when preparing is complete a response indicator is placed with the ResourceGroupManager, which will then be sent back to the listener as part of the application's primary frame loop thread.

Definition at line 118 of file OgreResource.h.

virtual const LightList& Ogre::MovableObject::queryLights ( void   )  const [virtual, 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.
void Ogre::Entity::reevaluateVertexProcessing ( void   )  [protected]

Trigger reevaluation of the kind of vertex processing in use.

void Ogre::Entity::refreshAvailableAnimationState ( void   ) 

Updates the internal animation state set to include the latest available animations from the attached skeleton.

Remarks:
Use this method if you manually add animations to a skeleton, or have linked the skeleton to another for animation purposes since creating this entity.
Note:
If you have called getAnimationState prior to calling this method, the pointers will still remain valid.
virtual void Ogre::MovableObject::removeQueryFlags ( unsigned long  flags  )  [virtual, inherited]

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

Definition at line 381 of file OgreMovableObject.h.

void Ogre::Entity::removeSoftwareAnimationRequest ( bool  normalsAlso  ) 

Removes a request for software animation.

Remarks:
Calling this decrements the entity's internal counter of the number of requests for software animation. If the counter is already zero then calling this method throws an exception. The 'normalsAlso' flag if set to 'true' will also decrement the internal counter of number of requests for software animation of normals.
virtual void Ogre::MovableObject::removeVisibilityFlags ( uint32  flags  )  [virtual, inherited]

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

Definition at line 409 of file OgreMovableObject.h.

void Ogre::Entity::restoreBuffersForUnusedAnimation ( bool  hardwareAnimation  )  [protected]

Internal method to restore original vertex data where we didn't perform any vertex animation this frame.

void Ogre::MovableObject::setCastShadows ( bool  enabled  )  [inherited]

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.

Definition at line 500 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setDebugDisplayEnabled ( bool  enabled  )  [virtual, inherited]

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.

Definition at line 544 of file OgreMovableObject.h.

static void Ogre::MovableObject::setDefaultQueryFlags ( uint32  flags  )  [static, inherited]

Set the default query flags for all future MovableObject instances.

Definition at line 388 of file OgreMovableObject.h.

static void Ogre::MovableObject::setDefaultVisibilityFlags ( uint32  flags  )  [static, inherited]

Set the default visibility flags for all future MovableObject instances.

Definition at line 416 of file OgreMovableObject.h.

void Ogre::Entity::setDisplaySkeleton ( bool  display  ) 

Tells the Entity whether or not it should display it's skeleton, if it has one.

virtual void Ogre::MovableObject::setLightMask ( uint32  lightMask  )  [virtual, 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
virtual void Ogre::MovableObject::setListener ( Listener listener  )  [virtual, inherited]

Sets a listener for this object.

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

Definition at line 427 of file OgreMovableObject.h.

void Ogre::Entity::setMaterial ( const MaterialPtr material  ) 

Sets the material to use for the whole of this entity.

Remarks:
This is a shortcut method to set all the materials for all subentities of this entity. Only use this method is you want to set the same material for all subentities or if you know there is only one. Otherwise call getSubEntity() and call the same method on the individual SubEntity.
void Ogre::Entity::setMaterialLodBias ( Real  factor,
ushort  maxDetailIndex = 0,
ushort  minDetailIndex = 99 
)

Sets a level-of-detail bias for the material detail of this entity.

Remarks:
Level of detail reduction is normally applied automatically based on the Material settings. However, it is possible to influence this behaviour for this entity by adjusting the LOD bias. This 'nudges' the material level of detail used for this entity up or down depending on your requirements. You might want to use this if there was a particularly important entity in your scene which you wanted to detail better than the others, such as a player model.
There are three parameters to this method; the first is a factor to apply; it defaults to 1.0 (no change), by increasing this to say 2.0, this entity would take twice as long to use a lower detail material, whilst at 0.5 this entity would use lower detail versions twice as quickly. The other 2 parameters are hard limits which let you set the maximum and minimum level-of-detail index to use, after all other calculations have been made. This lets you say that this entity should never be simplified, or that it can only use LODs below a certain level even when right next to the camera.
Parameters:
factor Proportional factor to apply to the distance at which LOD is changed. Higher values increase the distance at which higher LODs are displayed (2.0 is twice the normal distance, 0.5 is half).
maxDetailIndex The index of the maximum LOD this entity is allowed to use (lower indexes are higher detail: index 0 is the original full detail model).
minDetailIndex The index of the minimum LOD this entity is allowed to use (higher indexes are lower detail. Use something like 99 if you want unlimited LODs (the actual LOD will be limited by the number of lod indexes used in the Material)
void Ogre::Entity::setMaterialName ( const String name,
const String groupName = ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME 
)

Sets the material to use for the whole of this entity.

Remarks:
This is a shortcut method to set all the materials for all subentities of this entity. Only use this method is you want to set the same material for all subentities or if you know there is only one. Otherwise call getSubEntity() and call the same method on the individual SubEntity.
void Ogre::Entity::setMeshLodBias ( Real  factor,
ushort  maxDetailIndex = 0,
ushort  minDetailIndex = 99 
)

Sets a level-of-detail bias for the mesh detail of this entity.

Remarks:
Level of detail reduction is normally applied automatically based on the Mesh settings. However, it is possible to influence this behaviour for this entity by adjusting the LOD bias. This 'nudges' the mesh level of detail used for this entity up or down depending on your requirements. You might want to use this if there was a particularly important entity in your scene which you wanted to detail better than the others, such as a player model.
There are three parameters to this method; the first is a factor to apply; it defaults to 1.0 (no change), by increasing this to say 2.0, this model would take twice as long to reduce in detail, whilst at 0.5 this entity would use lower detail versions twice as quickly. The other 2 parameters are hard limits which let you set the maximum and minimum level-of-detail version to use, after all other calculations have been made. This lets you say that this entity should never be simplified, or that it can only use LODs below a certain level even when right next to the camera.
Parameters:
factor Proportional factor to apply to the distance at which LOD is changed. Higher values increase the distance at which higher LODs are displayed (2.0 is twice the normal distance, 0.5 is half).
maxDetailIndex The index of the maximum LOD this entity is allowed to use (lower indexes are higher detail: index 0 is the original full detail model).
minDetailIndex The index of the minimum LOD this entity is allowed to use (higher indexes are lower detail). Use something like 99 if you want unlimited LODs (the actual LOD will be limited by the number in the Mesh)
void Ogre::Entity::setPolygonModeOverrideable ( bool  PolygonModeOverrideable  ) 

Sets whether the polygon mode of this entire entity may be overridden by the camera detail settings.

virtual void Ogre::MovableObject::setQueryFlags ( uint32  flags  )  [virtual, inherited]

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.

Definition at line 373 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setRenderingDistance ( Real  dist  )  [virtual, inherited]

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

Parameters:
dist Distance beyond which the object will not be rendered (the default is 0, which means objects are always rendered).

Definition at line 295 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setRenderQueueGroup ( uint8  queueID  )  [virtual, inherited]

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.

void Ogre::Entity::setRenderQueueGroup ( uint8  queueID  ) 

Overridden - see MovableObject.

void Ogre::Entity::setRenderQueueGroupAndPriority ( uint8  queueID,
ushort  priority 
)

Overridden - see MovableObject.

virtual void Ogre::MovableObject::setRenderQueueGroupAndPriority ( uint8  queueID,
ushort  priority 
) [virtual, inherited]

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.
void Ogre::Entity::setSkipAnimationStateUpdate ( bool  skip  ) 

Entity's skeleton's AnimationState will not be automatically updated when set to true.

Useful if you wish to handle AnimationState updates manually.

Definition at line 771 of file OgreEntity.h.

virtual void Ogre::MovableObject::setUserAny ( const Any anything  )  [virtual, inherited]
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.

Definition at line 310 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setVisibilityFlags ( uint32  flags  )  [virtual, inherited]

Sets the visiblity flags for this object.

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

Definition at line 401 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setVisible ( bool  visible  )  [virtual, inherited]

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.

Reimplemented in Ogre::Light.

void Ogre::Entity::shareSkeletonInstanceWith ( Entity entity  ) 

Shares the SkeletonInstance with the supplied entity.

Note that in order for this to work, both entities must have the same Skeleton.

bool Ogre::Entity::sharesSkeletonInstance (  )  const

Returns whether this entity shares it's SkeltonInstance with other entity instances.

Definition at line 638 of file OgreEntity.h.

void Ogre::Entity::stopSharingSkeletonInstance (  )

Can be overridden if the subclass needs to do additional things.

Parameters:
edgeData The edge information to update
lightPos 4D vector representing the light, a directional light has w=0.0
virtual void Ogre::MovableObject::visitRenderables ( Renderable::Visitor visitor,
bool  debugRenderables = false 
) [pure virtual, inherited]

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:
visitor Pointer 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.
debugRenderables If false, only regular renderables will be visited (those for normal display). If true, debug renderables will be included too.

Implemented in Ogre::InstancedGeometry::BatchInstance, Ogre::Light, Ogre::ManualObject, Ogre::MovablePlane, Ogre::ParticleSystem, Ogre::StaticGeometry::Region, and Ogre::TerrainQuadTreeNode::Movable.
