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

inlinevirtualinherited

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::SubEntity.

virtual bool Ogre::Renderable::getCastsShadows ( void  ) const

inlinevirtualinherited

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 in Ogre::TerrainQuadTreeNode::Rend, Ogre::SubEntity, Ogre::InstancedGeometry::GeometryBucket, and Ogre::StaticGeometry::GeometryBucket.

Definition at line 224 of file OgreRenderable.h.

const Vector4& Ogre::Renderable::getCustomParameter ( size_t  index ) const

inlineinherited

Gets the custom value associated with this Renderable at the given index.

Parameters

index

Index of the parameter to retrieve.

ShadowRenderable* Ogre::ShadowRenderable::getLightCapRenderable ( void  )

inlineinherited

Get the light cap version of this renderable.

Definition at line 90 of file OgreShadowCaster.h.

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

virtualinherited

Implements Ogre::Renderable.

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

inlinevirtualinherited

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.

Definition at line 66 of file OgreShadowCaster.h.

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.

Implements Ogre::Renderable.

Definition at line 74 of file OgreShadowCaster.h.

virtual Technique* Ogre::Renderable::getTechnique ( void  ) const

inlinevirtualinherited

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 in Ogre::TerrainQuadTreeNode::Rend, Ogre::InstanceBatch, Ogre::InstancedGeometry::GeometryBucket, Ogre::StaticGeometry::GeometryBucket, and Ogre::SubEntity.

Definition at line 94 of file OgreRenderable.h.

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

Definition at line 178 of file OgreRenderable.h.

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.

Parameters

index

Index of the parameter to check for existence.

See also

setCustomParameter for full details.

Definition at line 259 of file OgreRenderable.h.

bool Ogre::ShadowRenderable::isLightCapSeparate ( void  ) const

inlineinherited

Does this renderable require a separate light cap?

Remarks

If possible, the light cap (when required) should be contained in the usual geometry of the shadow renderable. However, if for some reason the normal depth function (less than) could cause artefacts, then a separate light cap with a depth function of 'always fail' can be used instead. The primary example of this is when there are floating point inaccuracies caused by calculating the shadow geometry separately from the real geometry.

virtual bool Ogre::ShadowRenderable::isVisible ( void  ) const

inlinevirtualinherited

Should this ShadowRenderable be treated as visible?

Definition at line 128 of file OgreRenderable.h.

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::BillboardChain.

Implements Ogre::ShadowRenderable.

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.

Definition at line 250 of file OgreRenderable.h.

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.

Definition at line 241 of file OgreRenderable.h.

void Ogre::ShadowRenderable::setMaterial ( const MaterialPtr &  mat )

inlineinherited

Set the material to be used by the shadow, should be set by the caller before adding to a render queue.

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

Sets RenderSystem private data.

Remarks

This should only be used by a RenderSystem

Definition at line 407 of file OgreRenderable.h.

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.
