T&L automatically works if you're using OpenGL transforms and lighting. Not too many people are using lighting, you only have 8 real lights.

Anyway, nvidias site gives optimization tips to get the best performance out of their particular hardware T&L(allegedly x4 performance), but that doesn't necessarily equate to good performance on future cards from other companies with T&L support.

I read the previous posts about using hardware oriented Transform and Lighting on cards that support it ie: GEFORCE. Does anyone have any URLs that would describe in more detail how a person would go about using hardware T&L? I realize the Dx7 sdk probably goes into some detail but I was wondering if there were any articles using OpenGL.

I read that the game Quake3 supports T&L automagically, i'm curious what sort of hoops a programmer has to jump thru to get hardware T&L to work with OpenGL.

Thanks for your help.

Many of the techniques they show you on their site are pretty much generic to any standard implementation of T&L (optimizing vertex order for the vertex cache and such). Their hardware doesn't really have any specific features that you can optimize for except maybe vertex blending. Not that I know of at least...
