So how would you go about calculating that without shaders/register combiners? EDIT: Using OpenGl.

I figured it out! What i needed this for was emboss bump mapping. I now this technique is obsolete for almost a decade but i did it just for fun. I was a kind of dissapointed that the effect was too subtle. Anyway i implemented the signed addition by using two textures.
