Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.
Note my suggestion was defining a custom DataRenderer. To get a general context for this, see the tutorial at: http://www.ssec.wisc.edu/~billh/dr_tutorial.html But you can probably get away with just the information in my earlier email, and the visad/bom/BarbRendererJ3D.java example. See its main() method for how to use a custom DataRenderer.
