TruForm on a Geforce card?

[Fuelrod]

Can someone explain why the Detonator drivers could not be updated to support TruForm or some variation of it?

From all I've read Truform is just an implementation of n-patches which are already defined by DirectX and OpenGL. In addition to this argument, there is a guy called "NitroGL" at http://mwill.hypermart.net/ that has made patches for Quake and UnrealTournament that implement TruForm on Radeon cards (i.e. an R200 is not required).

I have download one of the TruForm demos at the site and upon execution I get "GL_ATIX_pn_triangles unsupported". Seem to me this is just an ATI OpenGL extension that could also be added to the Detonator driver set.

Can anyone give a good explanation?

Let's linkify that!

The problem is that it'd have to be done in software (ie the CPU) so it would be far too slow.

You may be able to do some tesselation on the CPU at a decent speed. Just make sure you have hardware T&amp;L for the rest. So in other words, you probably can.

GeForce hardware is capable of doing it in software easily, just like Radeon. All you need is extension that supports, which Nvidia may or may not release.

GeForce 3 can do much more complex effects that N-Patches with glEvaluatorNV in hardware, but that requires extensive coding...
