26 * This functions similarly to a LightAttrib or ClipPlaneAttrib. It indicates
27 * the set of occluders that modify the geometry at this level and below.
28 * Unlike a ClipPlaneAttrib, an OccluderEffect takes effect immediately when
29 * it is encountered during traversal, and thus can only add occluders; it may
30 * not remove them.
