Hi, Sorry it took so long to reply, I don't have email at my work account right now. Ok, I took a screen shot of the green glow and put it up on my school website at www.stanford.edu/~vjchem the last link, "Visad Green Glow" will be the picture. The more I look at it, the more sure I am that the problem is java3d, not visad, but any ideas you have will be appreciated. thanks, vj Hi Vijay, > this might be a java3d implementation question, but I'll ask anyway.

Hopefully you don't need a priest. But seriously, I wasn't able to duplicate the problem using 'java Test20' which allows me to interactively experiment with alpha values = 0. The fact that the green area doesn't rotate with the display sounds very strange. My laptop has a defective area on its screen and your problem sounds like that. If you can email a GIF image it might help. Off hand it doesn't sound like a VisAD problem. Cheers, Bill
