virtual void GenerateShadow (  VertexBufferPtr &  pkVertexBuffer, PolygonBufferPtr &  pkPolygonBuffer, BoundingVolume *  pkBoundingVolume, const Matrix &  rkTransform, const Matrix &  rkInvTransform )  [pure virtual]

Generate shadow Parameters: pkVertexBuffer  Vertex buffer for input geometry pkPolygonBuffer  Polygon buffer for input geometry pkBoundingVolume  Bounding volume for input geometry rkTransform  Transformation matrix rkInvTransform  Inverse transformation matrix Implemented in StencilShadowGenerator.

bool IsActive (   )  const [inline, inherited]

Query state of object Returns: true if active, false if not

void Activate (   )  [inline, virtual, inherited]

Activate object

void Deactivate (   )  [inline, virtual, inherited]

Deactivate object

bool Toggle (   )  [inline, inherited]

Toggle active state. This method does not need to be overloaded, it is only a wrapper to Activate and Deactivate Returns: true if activated, false if deactivated
