Abstract
A method, apparatus and article of manufacture are provided for performing area rasterization using sense points. Upon receipt of a primitive, e.g. a triangle, line equation coefficients of line equations are determined for lines that define the primitive. Thereafter, a plurality of points is positioned on or near the primitive. Such points define an enclosed convex region. Next, the line equations are evaluated at the points. During operation, the points and convex region are moved based on the evaluation of the line equations for the purpose of identifying an area in the primitive for rendering pixels therein.
