1. A method for performing conservative rasterization in a processor, the method comprising: determining vertices of a primitive; determining a set of edge equations based on the determined vertices to define edges of the primitive, wherein the edge equations are based on an edge shifting parameter plus an offset, wherein the offset is based on a number of fractional bits supported by the processor; determining pixels that touch the edges of the primitive using the determined edge equations; and rasterizing the primitive using the determined pixels.
