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.

Manually sets the hlms hashes. Don't call this directly.

Reimplemented in Ogre::SubItem.

◆ _setNullDatablock()

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

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

Accessor method to read mesh data.

◆ 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

◆ 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

◆ getUseIdentityViewProjMatrixIsDynamic()

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

Returns whether the Hlms implementation should evaluate getUseIdentityProjection per object at runtime, or if it can assume the Renderable will remain with the same setting until the datablock is flushed (performance optimization)

Remarks
Hlms implementations may ignore this setting (e.g. assume always true or always false) or even not support identity matrix overrides at all. For example currently Unlit supports them all, but will assume this returns always true if getUseIdentityWorldMatrix returns false.

◆ getUseIdentityWorldMatrix()

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

Returns whether the world matrix is an identity matrix.

Remarks
It is up to the Hlms implementation whether to honour this request. Take in mind changes of this value at runtime may not be seen until the datablock is flushed. It is implemented as a virtual call because this functionality isn't required very often (hence we save per-Renderable space for those that don't use it) and this function will be called at creation time to use a different shader; not during rendering time per Renderable.

Reimplemented in Ogre::v1::BillboardSet.

◆ getUserAny()

◆ postRender()

RenderSystem rsys 
)
inlinevirtualinherited

Called immediately after the Renderable has been rendered.

◆ 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::v1::BillboardChain.

◆ 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.

◆ resetIndexDataStartEndIndex()

void Ogre::v1::SubEntity::resetIndexDataStartEndIndex ( )

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

◆ 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.

◆ setDatablock() [1/2]

virtual void Ogre::v1::SubEntity::setDatablock ( HlmsDatablock datablock)
virtual

Assigns a datablock (i.e. HLMS Material) to this renderable.

Reimplemented from Ogre::Renderable.

◆ setDatablock() [2/2]

void Ogre::Renderable::setDatablock ( IdString  datablockName)
inherited

Assigns a datablock (i.e.

HLMS material) based on its unique name.

Remarks
An null IdString() is valid, it will use the default material

◆ setDatablockOrMaterialName()

void Ogre::Renderable::setDatablockOrMaterialName ( String  materialName,
String  groupName 
)
inherited

First tries to see if an HLMS datablock exist with the given name, if not, tries to search among low level materials.

◆ setIndexDataEndIndex()

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.

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

◆ 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.

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

◆ setMaterial()

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

Sets a 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.

Reimplemented from Ogre::Renderable.

◆ setMaterialName()

void Ogre::Renderable::setMaterialName ( const String name,
const String groupName 
)
inherited

Sets the name of the Material to be used. Prefer using HLMS setHlms.

◆ setPolygonModeOverrideable()

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

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.

◆ setPoseWeight()

void Ogre::Renderable::setPoseWeight ( size_t  index,
float  w 
)
inherited

◆ setRenderQueueSubGroup()

void Ogre::Renderable::setRenderQueueSubGroup ( uint8  subGroup)
inlineinherited

Sets the render queue sub group.

Remarks
Within the same RenderQueue ID, you may want to have the renderables to have a specific order (i.e. have a mesh, but the hair submesh with alpha blending needs to be rendered last).
RenderQueue Subgroups are useful for manually sorting objects, just like RenderQueue IDs. However, RenderQueue IDs can also be useful for skipping large number of objects through clever compositing and thus a performance optimization. Subgroups cannot be used for such optimizations.
Parameters
subGroupThe sub group. This value can't exceed OGRE_MAKE_MASK( SubRqIdBits ) RenderQueue

◆ 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

◆ 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.
