C++ / OpenGL

How do I go about bumpmapping a simple polygon (in my case, a square)? I've already imported the normal map (as a bitmap) and can use it as a texture, but there seems to be a shit-ton more functions that I need to call for it to actually used as a normal map on the polygon.

Can you even do normal mapping in OpenGL while still using the fixed-function pipeline? I was under the impression that you had to write a shader program to do it. Though, knowing OpenGL there's probably some pre-SL1.0 extensions which aren't supported on half the chipsets to do normal mapping, but what the fuck.

tl;dr use a shader.

tl;dr use a cudder

tl;dr use a gegenschein

I know how the math behind it works. Knowing what to call is something else.

Goddamn.

GPU asm then?

There was some sort of fixed function bump mapping in DirectX but that is pretty deprecated now. I'm betting you have to use the progrmaming pipeline and write the code yourself.

yeah it's kinda like expecting shadows to be in the FFP too.

which would be sweet (I don't mean that in the modern cool-guy kinda usage of the word).

Modern software is about reinventing the wheel every time, so don't count on it
