Hardware bump mapping

I’m currently creating my engine 3D and I can not find any documentation concerning the hardware bump mapping. I found many tutorial about bump mapping but they’re all about cpu’s bump with equation and something like that… It must be an opengl extension.

Can anybody help me?

Have you seen this?http://www.nvidia.com/marketing/developer/devrel.nsf/TechnicalDemosFrame?OpenPage
There are at least two other bump mapping demos in that tree.

Thanks 4 this URL, I didn’t know that NVidia create demo for old 3D card like TNT since I haven’t got a GeForce 2048 in my computer.
I’ll try this example this evening and i hope it will solve my problems.

thx a lot.
