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.

Member Function Documentation

◆ getMaterialName()

const String& Ogre::SubEntity::getMaterialName ( ) const

Gets the name of the Material in use by this instance.

◆ setMaterialName()

void Ogre::SubEntity::setMaterialName	(	const String &	name,
		const String &	groupName = `ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME`
	)

Sets the name of the Material to be used.

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.

◆ setMaterial()

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

Sets the name of the Material to be used.

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.

◆ setVisible()

void Ogre::SubEntity::setVisible ( bool visible )

Tells this SubEntity whether to be visible or not.

◆ isVisible()

bool Ogre::SubEntity::isVisible ( void ) const

inline

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

◆ setRenderQueueGroup()

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

Sets the render queue group this SubEntity 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, the SubEntity will use either the Entity's queue or it will use the default (RenderQueue::getDefaultQueueGroup).

: See Entity::setRenderQueueGroup 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.

◆ setRenderQueueGroupAndPriority()

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

Sets the render queue group and group priority this SubEntity 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).

: See Entity::setRenderQueueGroupAndPriority 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.

Accessor method to read mesh data.

◆ getParent()

Entity* Ogre::SubEntity::getParent ( void ) const

inline

Accessor to get parent Entity.

◆ getMaterial()

const MaterialPtr& Ogre::SubEntity::getMaterial ( void ) const

inlineoverridevirtual

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.

◆ getTechnique()

Technique* Ogre::SubEntity::getTechnique ( void ) const

overridevirtual

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 from Ogre::Renderable.

◆ getRenderOperation()

void Ogre::SubEntity::getRenderOperation ( RenderOperation & op )

overridevirtual

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

Implements Ogre::Renderable.

◆ setIndexDataStartIndex()

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

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

Default value is zero so that the entire index buffer is used when drawing. Valid values are zero to getIndexDataEndIndex()

◆ getIndexDataStartIndex()

size_t Ogre::SubEntity::getIndexDataStartIndex ( ) const

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

See also: setIndexDataStartIndex

◆ setIndexDataEndIndex()

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

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

Default value is SubMesh::indexData::indexCount so that the entire index buffer is used when drawing. Valid values are mStartIndex to SubMesh::indexData::indexCount

◆ getIndexDataEndIndex()

size_t Ogre::SubEntity::getIndexDataEndIndex ( ) const

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

◆ resetIndexDataStartEndIndex()

void Ogre::SubEntity::resetIndexDataStartEndIndex ( )

Reset the custom start/end index to the default values.

◆ getWorldTransforms()

void Ogre::SubEntity::getWorldTransforms ( Matrix4 * xform ) const

overridevirtual

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.

◆ getNumWorldTransforms()

unsigned short Ogre::SubEntity::getNumWorldTransforms ( void ) const

overridevirtual

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 from Ogre::Renderable.

◆ getSquaredViewDepth()

Real Ogre::SubEntity::getSquaredViewDepth ( const Camera * cam ) const

overridevirtual

Returns the squared distance between the camera and this renderable.

Used to sort transparent objects. Squared distance is used to avoid having to perform a square root on the result.

Implements Ogre::Renderable.

◆ getLights()

const LightList& Ogre::SubEntity::getLights ( void ) const

overridevirtual

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.

◆ getCastsShadows()

bool Ogre::SubEntity::getCastsShadows ( void ) 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.

Reimplemented from Ogre::Renderable.

◆ _getSkelAnimVertexData()

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

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

◆ _getSoftwareVertexAnimVertexData()

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

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.
