Class Color4

java.lang.Object
  net.java.joglutils.msg.nodes.Node
      net.java.joglutils.msg.nodes.Color4

public class Color4
extends Node

Represents a set of 4-valued colors which are applied on a per-vertex basis to any drawn polygons. Currently the color can only be bound to one material parameter of the fixed-function OpenGL pipeline, defaulting to "ambient and diffuse".

For correct rendering results, the colors stored in this node should have their alpha premultiplied; in other words, the red, green, and blue (x, y, and z components of the stored vectors) should be multiplied by the alpha value (the w component) before storing them in this node.
