Glass

Hello,

Sure you can do it, developer.nvidia.com has some really nice examples. I think they use Cg on a rabbit model to make it look like it''s made of glass. This is a screenie:

You can easily find the source on the nvidia website. If you don''t like Cg you can always look at the code and port it to the appropriate shader.

Ah - yeah, I forgot I had that demo I''ll check the source and see how they do it. But I have a feeling they use environment maps; you can''t generate those on-the-fly, can you?

And it probably only works with NVidia specific extensions.....

Ah, that''s what I was really wondering about. I guess if the model is fairly small, then it should be ok...

Also, you dont have to generate the environement for every frame.
Doing it once before the effect should be enough to trick the eye.
