All Implemented Interfaces:

Savable, JmeCloneable, java.lang.Cloneable

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;

Constructor Detail

SpotLightShadowFilter

protected SpotLightShadowFilter()

Used for serialization. Use SpotLightShadowFilter#SpotLightShadowFilter(AssetManager assetManager, int shadowMapSize) instead.

SpotLightShadowFilter

public SpotLightShadowFilter(AssetManager assetManager,
                             int shadowMapSize)

Creates a SpotLight Shadow Filter

Parameters:

assetManager - the application asset manager

shadowMapSize - the size of the rendered shadowmaps (512,1024,2048, etc...) the more quality, the less fps).
