Per-Pixel Displacement Mapping with Distance Functions - sample chapter from GPU Gems 2

A sample chapter from GPU Gems 2 is available entitled “Per-Pixel Displacement Mapping with Distance Functions”, a technique for adding small-scale details to surfaces using displacement mapping of objects in a pixel shader. The algorithm, implemented using the OpenGL API, Cg and Sh, significantly increases the perceived geometric complexity of a scene while maintaining real-time performance.
