Abstract
The current invention involves new systems and methods for providing variable rasterization performance suited to the size and shape of the primitives being rendered. Portions of pixel tiles that are fully covered by a graphics primitive are encoded and processed by the system as rectangles, rather than expanding to explicit samples. This accelerates the rendering of large primitives without increasing the computation resources used for rasterization. In some embodiments, these fully-covered regions can be rendered compressed without ever expanding into samples.
