I found this tutorial on bumpmapping: http://www.paulsprojects.net/tutorials/ ... ebump.html

It also shows how to use your existing opengl lights (only one)

I've discovered that tutorial some months ago and already implemented that bumpmap-technique both on the torus that's shown in that tutorial and on MD3-Models. If there is interest, I'm going to release the source.
But it's no competition for bumpmapping with a shader, since you have to do at least two passes or even three when you also want specular highlight. But the advantage is the fact that it also runs on older hardware.

Please do it. All i get is a black thingy, but no bumpmapping...

Here you go : simplebump.zip (~600K, Bin+Source+Texture)

I've just cleaned up the code and removed all unnecessary libraries, so that it should compile just fine. If you're using Delphi 6 or lower, remove Variants form the uses-clausel. Don't know why Delphi 7 always wants to include that, even if you don't use it...

Edit : I noticed that I made a small fault. Please replace the following line (no.182) :

with this :

Normalmaps shouldn't be mipmapped, and you would notice that if moving in and out of a scene.

Thanks i have a look at it. Also i managed to make my version to work.

i looked at your code and it seems some units are missing.

where can i find the command glmult3f?

Sorry, I forgot to include a unit from my basecode-folder. I've attached it. It contains some needed functions from my math library (like glMult3f) and also the functions to create the torus (+tangents and normals).
