Axel already mentioned this, but you'll need to check if your video
card has 3-D texture mapping or not. Beyond that, there're known problems

But when I tried to use the volume data to color the surface by "Volume", I got invariably a uniform white color. I thought maybe the electronic potential was not calculated propperly. So I tried one of the demos, and I got the same uniform color.
