I am a phD student working on Physics. I have a 
problem with graphics and hope you guy can help.


I have four sheet of closed surfacees entangle 
each other. I want to see how they are changing 
as I change one or two parameters. I hope to 
keep figure fade-out while next figure fade-in.

I have some softwares, but they do not fit.
does anyone have suggestion for this problem?

Thank you.

   The easiest way to do this is probably to construct each display screen while actually displaying the previous one. Therefore, at the end of the cycle, you have two graphic screens in memory - one actually in screen memory (old screen) and the just-calculated/constructed screen. In one program I had seen a while ago, when the new screen is swapped into screen memory, the effect was a pixelated dissolve.

   Hope this helps.
