I recently started using custom shader. Shader can do diffuse and specular lighting and normal mapping. But normal mapping is causing really ugly artifacts (some sort of pixeling noise) for textures ...
I'm having some issue changing a basic lighting shader to take a normal texture and a diffuse texture for a model and then using the normal texture for lighting. The code is very simple and i can't ...
See this paper: ftp://download.nvidia.com/developer/Papers/Mipmapping_Normal_Maps.pdf They describe the very simple implementation of an algorithm for antialiasing normal maps. I don't understand ...
