Hi guys,

I'm still busy with my 3D engine, so far so good. But now I have stumbled upon some questions regarding water/terrain rendering (basicly the same).

I want to have a grid that is transformed by a heightmap in real time.

What I want to know is what is the best approach.
- I can calculate everyting on the CPU, what would be kinda slow.
- I can do texture lookup in a vertex shader 3.0. However there are some restrictions and limitations on this one, and it is not supported on ATI cards I think.

Anyone any idea how to render a grid with real-time animated waves?

Thanks in advance!
