Ole and I promised to share the slides from our talk at the SIGGRAPH 2011 Studio. The presentation covers various graphics techniques that use depth, normals and color buffers. The methods range from improving standard techniques to creating entirely new ones, like approximate volumetric effects or advanced image post-processing. The buffers used are in many cases the natural products of the rendering pipeline and offer a way to infer surprisingly much information about the scene, thus allowing for very rich and fast graphics effects.
It may be a worthy read both for artists and programmers, as we discuss the possibilities of some unusual special effects and their technical side.
