java.lang.Object
  extended by net.sf.j3d.threeD.raytracer.shaders.BlendingShader
All Implemented Interfaces:
ColorProducer, Shader, Editable, Producer

public class BlendingShader
extends Object
implements Shader, Editable

A BlendingShader object provides a method for blending values from two different ColorProducer instances based on lighting. This is best for cool to warm shading or cartoon shading.
