In a graphics processing pipeline, a processing unit establishes a bounding box around a polygon in order to identify sample points that are covered by the polygon. For a given sample point included within the bounding box, the processing unit constructs a set of lines that intersect at the sample point, where each line in the set of lines is parallel to at least one side of the polygon. When all vertices of the polygon reside on one side of at least one line in the set of lines, the processing unit may reduce the size of the bounding box to exclude the sample point.
