Has anyone got an example of how to display a normal map (Bump Map - DOT3) on a model in OpenGL, without resorting to Shaders? (Although it may come to shaders in the end).
I am hoping to add a 'Paint Normal-Map' option to TattooMax, but have come to realise that, although I can make a normal map, I currently have no idea how to display one on a 3D model. :|
Is it easier to go with Shaders or is it better to be using the Fixed Functionality Pipeline?
