This paper presents a hardware architecture for a configurable shader with pre-filtered environment mapping and twist/bump pattern mapping. Our architecture enables per-pixel shading calculation, which can be programmed by means of lookup tables, random-access memories (RAMs) and read-only memories (ROMs), and provides real-time rendering with various shading and reflectance models, such as Blinn-Phong, Cook-Torrance, and Ward.
