OccluderGeometry provides a sepecialised geometry representation of objects in scene that occlude light and therefore cast shadows.
OccluderGeometry supports the computation of silhouette edges and shadow volume geometries, as well as use as geometry that one can rendering into a shadow map or end caps for the ZP+ algorithm. OccluderGeometry may be of the same resolution as an underlying geometry that it represents, or can be of lower resolution and combine manager seperate geometries together into a single shadow casting object. OccluderGeometry may be attached as UserData to Nodes or to Drawables.
