OpenGL Shading Language

This guide explains how graphics hardware programmability can be exposed through a high-level language in the cross-platform 3D graphics API, OpenGL. Intended for application programmers, it introduces the OpenGL commands used to create and manipulate shaders, and provides examples of stored texture shaders, procedural texture shaders, animated shaders, non-photorealistic shaders, and shaders for imaging. Thirty color plates and an API function reference are provided.
