Detailed Description

Utility class which defines the sub-parts of an Entity.

Remarks
Just as meshes are split into submeshes, an Entity is made up of potentially multiple SubMeshes. These are mainly here to provide the link between the Material which the SubEntity uses (which may be the default Material for the SubMesh or may have been changed for this object) and the SubMesh data.
The SubEntity also allows the application some flexibility in the material properties for this section of a particular instance of this Mesh, e.g. tinting the windows on a car model.
SubEntity instances are never created manually. They are created at the same time as their parent Entity by the SceneManager method createEntity.

Constructor & Destructor Documentation

◆ ~SubEntity()

Ogre::v1::SubEntity::~SubEntity ( )
override

Destructor.

Member Function Documentation

◆ _getBuffersMarkedForAnimation()

bool Ogre::v1::SubEntity::_getBuffersMarkedForAnimation ( ) const
inline

Are buffers already marked as vertex animated?

◆ _getHardwareVertexAnimVertexData()

VertexData* Ogre::v1::SubEntity::_getHardwareVertexAnimVertexData ( )

Advanced method to get the hardware morph vertex information.

Note
The positions/normals of the returned vertex data is in object space.

◆ _getSkelAnimTempBufferInfo()

TempBlendedBufferInfo* Ogre::v1::SubEntity::_getSkelAnimTempBufferInfo ( )

Advanced method to get the temp buffer information for software skeletal animation.

◆ _getSkelAnimVertexData()

VertexData* Ogre::v1::SubEntity::_getSkelAnimVertexData ( )

Advanced method to get the temporarily blended vertex information for entities which are software skinned.

Remarks
Internal engine will eliminate software animation if possible, this information is unreliable unless added request for software animation via Entity::addSoftwareAnimationRequest.
Note
The positions/normals of the returned vertex data is in object space.

◆ _getSoftwareVertexAnimVertexData()

VertexData* Ogre::v1::SubEntity::_getSoftwareVertexAnimVertexData ( )

Advanced method to get the temporarily blended software morph vertex information.

Remarks
Internal engine will eliminate software animation if possible, this information is unreliable unless added request for software animation via Entity::addSoftwareAnimationRequest.
Note
The positions/normals of the returned vertex data is in object space.

◆ _getVertexAnimTempBufferInfo() [1/2]

TempBlendedBufferInfo* Ogre::v1::SubEntity::_getVertexAnimTempBufferInfo ( )

Advanced method to get the temp buffer information for software morph animation.

◆ _getVertexAnimTempBufferInfo() [2/2]

const TempBlendedBufferInfo* Ogre::v1::SubEntity::_getVertexAnimTempBufferInfo ( ) const

◆ _markBuffersUnusedForAnimation()

void Ogre::v1::SubEntity::_markBuffersUnusedForAnimation ( )

Mark all vertex data as so far unanimated.

◆ _markBuffersUsedForAnimation()

void Ogre::v1::SubEntity::_markBuffersUsedForAnimation ( )

Mark all vertex data as animated.

◆ _restoreBuffersForUnusedAnimation()

void Ogre::v1::SubEntity::_restoreBuffersForUnusedAnimation ( bool  hardwareAnimation)

Internal method to copy original vertex data to the morph structures should there be no active animation in use.

◆ _setNullDatablock()

void Ogre::v1::SubEntity::_setNullDatablock ( )
overridevirtual

Sets the datablock to a null pointer.

Use case: If you will be destroying an HlmsDatablock and all Renderables associated by it; it makes no sense to change the Renderable's datablock to a default one, only to be destroyed immediately after (you pay an unnecessary performance price).

Remarks
Do not attempt to render a Renderable whose datablock has been set to null. It will crash. You can call setDatablock afterwards though. Use at your own risk, hence the _underscore. See http://ogre3d.org/forums/viewtopic.php?f=25&t=91791&p=534476#p534476

GpuProgramParameters params 
) const

Reimplemented from Ogre::Renderable.

◆ getCastsShadows()

bool Ogre::v1::SubEntity::getCastsShadows ( ) const
overridevirtual

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.

◆ getIndexDataEndIndex()

size_t Ogre::v1::SubEntity::getIndexDataEndIndex ( ) const

Returns the current value of the start index used for drawing.

void Ogre::v1::SubEntity::setIndexDataEndIndex ( size_t  end_index)

Tells this SubEntity to draw a subset of the SubMesh by adjusting the index buffer extents.

◆ setIndexDataStartIndex()

void Ogre::v1::SubEntity::setIndexDataStartIndex ( size_t  start_index)

Tells this SubEntity to draw a subset of the SubMesh by adjusting the index buffer extents.

◆ setMaterial()

void Ogre::v1::SubEntity::setMaterial ( const MaterialPtr material)

Remarks
By default a SubEntity uses the default Material that the SubMesh uses. This call can alter that so that the Material is different for this instance.
