Class RigidBodyStateShader

java.lang.Object
  net.sf.j3d.physics.shaders.RigidBodyStateShader

All Implemented Interfaces:

ColorProducer, Shader, Producer

public class RigidBodyStateShader
extends Object
implements Shader

A RigidBodyStateShader object can be used to modify the display of other shaders based on a property of the state of a RigidBody object. A RigidBodyStateShader modifies the light direction and intensity based on the direction and intensity of either the velocity or force experienced by a rigid body.
