Detailed Description

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

Remarks: Just as meshes are split into submeshes, an Item is made up of potentially multiple SubMeshes. These are mainly here to provide the link between the Material which the SubItem uses (which may be the default Material for the SubMesh or may have been changed for this object) and the SubMesh data.

: The SubItem 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.

: SubItem instances are never created manually. They are created at the same time as their parent Item by the SceneManager method createItem.

◆ _setHlmsHashes()

virtual void Ogre::SubItem::_setHlmsHashes	(	uint32	hash,
		uint32	casterHash
	)

virtual

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

Reimplemented from Ogre::Renderable.

◆ _setNullDatablock()

virtual void Ogre::Renderable::_setNullDatablock ( void )

virtualinherited

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

Reimplemented in Ogre::v1::BillboardSet, and Ogre::v1::SubEntity.

◆ _updateCustomGpuParameter()

virtual void Ogre::Renderable::_updateCustomGpuParameter	(	const GpuProgramParameters_AutoConstantEntry &	constantEntry,
		GpuProgramParameters *	params
	)		const

virtualinherited

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::v1::SubEntity.

Parameters

index Index of the parameter to retrieve.

virtual

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.

◆ getMaterial()

MaterialPtr Ogre::Renderable::getMaterial ( void ) const

inherited

Retrieves the material this renderable object uses.

It may be null if it's using the HLMS. getDatablock

◆ getNumPoses()

unsigned short Ogre::Renderable::getNumPoses ( void ) const

inherited

◆ getNumWorldTransforms()

virtual unsigned short Ogre::Renderable::getNumWorldTransforms ( void ) const

inlinevirtualinherited

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 in Ogre::v1::BorderRenderable, and Ogre::v1::SubEntity.

◆ getRenderQueueSubGroup()

uint8 Ogre::Renderable::getRenderQueueSubGroup ( void ) const

inlineinherited

◆ getSubMesh()

SubMesh* Ogre::SubItem::getSubMesh ( void ) const

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()

virtual OGRE_DEPRECATED const Any& Ogre::Renderable::getUserAny ( void ) const

inlinevirtualinherited

Deprecated:: use UserObjectBindings::getUserAny via getUserObjectBindings() instead.

Retrieves the custom user value associated with this object.

◆ getUserObjectBindings() [1/2]

See also: UserObjectBindings::setUserAny.

◆ getUserObjectBindings() [2/2]

const UserObjectBindings& Ogre::Renderable::getUserObjectBindings ( ) const

inlineinherited

Return an instance of user objects binding associated with this class.

You can use it to associate one or more custom objects with this class instance.

See also: UserObjectBindings::setUserAny.

◆ getVaos()

const VertexArrayObjectArray& Ogre::Renderable::getVaos ( VertexPass vertexPass ) const

inlineinherited

◆ getWorldTransforms()

virtual void Ogre::SubItem::getWorldTransforms ( Matrix4 * xform ) const

virtual

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.

See also: Matrix4::isAffine.

Implements Ogre::Renderable.

◆ hasCustomParameter()

bool Ogre::Renderable::hasCustomParameter ( size_t index ) const

inlineinherited

Checks whether a custom value is associated with this Renderable at the given index.

◆ postRender()

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

index Index of the parameter to remove.

See also: setCustomParameter for full details.

◆ 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.

◆ setDatablock() [1/2]

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

◆ setDatablock() [2/2]

virtual void Ogre::Renderable::setDatablock ( HlmsDatablock * datablock )

virtualinherited

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

Reimplemented in Ogre::v1::BillboardSet, and Ogre::v1::SubEntity.

◆ 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.

◆ setMaterial()

virtual void Ogre::Renderable::setMaterial ( const MaterialPtr & material )

virtualinherited

Sets the given material. Overrides HLMS materials.

Reimplemented in Ogre::v1::BillboardSet, Ogre::v1::SubEntity, and Ogre::v1::SimpleRenderable.

◆ 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

override true means that a lower camera detail will override this renderables detail level, false means it won't.

◆ setPoseWeight() [1/2]

void Ogre::SubItem::setPoseWeight	(	const Ogre::String &	poseName,
		float	w
	)

◆ setPoseWeight() [2/2]

		float	w
	)

inherited

Referenced by getParent().

◆ 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

subGroup The 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.

See also: Renderable::getUseIdentityView

◆ setUserAny()

virtual OGRE_DEPRECATED void Ogre::Renderable::setUserAny ( const Any & anything )

inlinevirtualinherited

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 Renderable. This can be a pointer back to one of your own classes for instance.
