What's the equivalent of DirectX tri patches in OpenGL? Is it the N-Triangle ATI extension? What about NVIDIA and other cards?

- you shouldn't count on it continuing to be supported though. And it is only available on ATi, if at all.

i believe that only was supported on a limited range of ati hardware at that (nvidia had also some patch tesselator extension there as well for a very limited period)
once geometry shaders come out, u should be able to implement it with more flexibility.
