Per Pixel Operations
Tremendous leverage (and cost) for operations that are done per pixel
leverage comes from variation per pixel - lighting, shading, texturing individually
cost comes from pipelined and parallel hardware to deliver computation at fill rates
- texture filtering
- texture / diffuse lighting modulation
- texture blending
- specular / Phong highlight addition
- fog / atmospheric effect blending
- frame buffer src / dst blending
- Z buffer read-modify-write and compare
