Abstract: A system, method, and computer program product are provided for conservative rasterization of primitives using an error term. In use, an edge equation is determined for each edge of a primitive, the edge equation having coefficients defining the edge of the primitive. Each edge of the primitive is shifted to enlarge the primitive by modifying coefficients of the edge equation defining the edge by an error term that is a predetermined amount. Pixels that intersect the primitive are then determined using the enlarged primitive.

Abstract: A system, method, and computer program product are provided for adjusting vertex positions. One or more viewport dimensions are received and a snap spacing is determined based on the one or more viewport dimensions. The vertex positions are adjusted to a grid according to the snap spacing. The precision of the vertex adjustment may increase as at least one dimension of the viewport decreases. The precision of the vertex adjustment may decrease as at least one dimension of the viewport increases.
