Bump mapping?

Where do I need to start to get bump mapping? I am not finding much info on bump mapping and need to understand what is involved and how and what info OpenGL needs to calculate a bump.

Thanks,

First, read the papers and demos on nVidia’s website.

Secondly, you’re not going to get bump mapping (unless you want to use 7 texture passes) with unextended OpenGL (at least, not 1.1. There may be enough texture_env_combine functions in 1.3).

Check nehe.gamedev.net. One of his tutorials goes into some detail on bumpmapping.
