Javadoc
Sets the color buffer reference to the specified
buffer object. The buffer contains either a java.nio.FloatBuffer
or java.nio.ByteBuffer object containing floating-point
or byte red, green,
blue, and, optionally, alpha values for each
vertex (for a total of 3*n or 4*n values, where
n is the number of vertices).
If the color buffer reference is null and colors are enabled
(that is, the vertexFormat includes either COLOR_3
or
COLOR_4
), the entire geometry array object is
treated as if it were null--any Shape3D or Morph node that uses
this geometry array will not be drawn.
