Package com.jme3.shadow

Class PssmShadowRenderer

java.lang.Object
com.jme3.shadow.PssmShadowRenderer
All Implemented Interfaces:
SceneProcessor
@Deprecated public class PssmShadowRenderer extends Object implements SceneProcessor
Deprecated.
use DirectionalLightShadowRenderer
PssmShadow renderer use Parallel Split Shadow Mapping technique (pssm)
It splits the view frustum in several parts and compute a shadow map for each one.
splits are distributed so that the closer they are from the camera, the smaller they are to maximize the resolution used of the shadow map.
This results in a better quality shadow than standard shadow mapping.

      Adjusts the partition of the shadow extend into shadow maps. Lambda is usually between 0 and 1. A low value gives a more linear repartition, resulting in consistent shadow quality over the extend, but near shadows could look very jagged. A high value gives a more logarithmic repartition, resulting in high quality for near shadows, but quality decreases rapidly with distance. The default value is 0.65 (the theoretical optimum).
      Parameters:
      lambda - the lambda value.
