/** ShadowPrimitive3D class
|
|
|
|
This 3D grouping primitive is used to define a shadow for
|
|
3d geometry by embedding it. The shadow of 3D objects are
|
|
2D polygons, so the shadow transformation is a 2D transformation.
|
|
|
|
If the Shadow3D flag is set, the shadow definition has to be
|
|
combined with the scene and camera definition to create the correct
|
|
projected shadow 2D-Polygons.
