Tuning the Raster Subsystem

Tuning the Raster Subsystem

An explosion of both data and operations is required to rasterize a polygon as individual pixels. Typically, the operations include depth comparison, Gouraud shading, color blending, logical operations, texture mapping, and possibly antialiasing. This section discusses the following techniques for tuning fill-limited drawing:

"Using Backface/Frontface Removal"
"Using Expensive Per-Fragment Operations Efficiently"
"Balancing Polygon Size and Pixel Operations"
"Clearing the Color and Depth Buffers Simultaneously"
