A Framework for Analyzing Real-Time Advanced Shading Techniques

SIGGRAPH 2000, 2001 and 2002 courses on real-time shading

Numerous techniques have been developed to perform advanced shading operations in real time. The real-time versions vary greatly from their original implementations due to the constraints of existing hardware and programming libraries. This paper introduces a grammar for articulating these modern real-time shading pipelines. We survey the existing techniques, using the grammar to classifies them into a taxonomy illustrating the commutations that differentiate the pipelines from the classical version and each other. The taxonomy follows a natural development that concludes with texture shading, which is applied to four advanced shaders to explore its versatility.
