In 1994, at the Proceedings of the 21st Annual Conference on Computer Graphics and Interactive Techniques, Gavin Miller and Peter Litwinowicz published a paper on “Efficient techniques for interactive texture placement”. This paper describes efficient algorithms for the placement and distortion of textures. The textures include surface color maps and environment maps. Affine transformations of …

Screen space ambient occlusion Is a pixel shader. By analyzing the scene depth buffer which is stored in a texture its possible to make a better approximate lighting model. For every pixel on the screen, the pixel shader samples the depth values around the current pixel and tries to compute the amount of occlusion from …
