Re: texture and light reflection

To do this you will need to write a custom DataRenderer that
extends visad.java3d.DefaulatRendererJ3D, and custom ShadowTypes
that extend all the ShadowTypes in the visad.java3d package.
The ShadowTypes need to override the method:

  public static Appearance makeAppearance(GraphicsModeControl mode,
                      TransparencyAttributes constant_alpha,
                      ColoringAttributes constant_color,
                      GeometryArray geometry, boolean no_material)

from visad.java3d.ShadowTypeJ3D, to change the various
attributes of the Java3D Appearance. The extension of
DataRenderer needs to override the makeShadow*Type()
methods, described in section 1.4 of the DataRenderer
tutorial at:

Good luck,
