public class SpotLightShadowFilter extends AbstractShadowFilter<SpotLightShadowRenderer>
This Filter does basically the same as a SpotLightShadowRenderer except it renders the post shadow pass as a fullscreen quad pass instead of a geometry pass. It's mostly faster than PssmShadowRenderer as long as you have more than about ten shadow receiving objects. The expense is the drawback that the shadow Receive mode set on spatial is ignored. So basically all and only objects that render depth in the scene receive shadows. See this post for more details http://jmonkeyengine.org/groups/general-2/forum/topic/silly-question-about-shadow-rendering/#post-191599 API is basically the same as the PssmShadowRenderer;
