Part I. Geometric Complexity
Today’s games are visually more interesting and complex than ever before. Geometric complexity—how many objects are visible and how detailed each looks—is one of the dimensions in which games are making leaps and bounds.
Advances in technology are partly responsible for these leaps and bounds: CPUs, memory, and buses all have become faster, but specifically GPUs are undergoing significant change and are becoming ever more powerful—at a rate faster than Moore’s Law.
These GPU changes include incorporating fixed-function processing for the vertex- and pixel-shading units, then generalizing those to be fully programmable. ...
