GLSL GPU 3D Graphics Programming

I have done a fair amount of GPU graphics programming using the Processing Java dialect. GPU programming can be carried out using many other languages also, but the main thing is not the host language but rather to understand GLSL, the GPU, the graphics algorithms and techniques, and of course the associated mathematics.


Simple screenshots illustrating some well known graphics algorithms and techniques:

None Phong illumination and Phong shading - note quality of specular highlight Cook-Torrance illumination - note polished material type shininess Texture mapped Death Star - admittedly not the highest quality texture image Texture mapped and spatial convolution Gaussian blurred Death Star Texture mapped and colour banded Death Star - note cartoon effect Texture mapped and displacement mapped Death Star - note displaced silhouette Bump mapped brick wall - note surface indentation shadowing
