1. A device, comprising: a bounding box module configured to calculate a bounding box of a given polygonal primitive describing a three-dimensional scene, the polygon polygonal primitive represented as one or more triangles; a translation module configured to translate each triangle from the three-dimensional realm to the two-dimensional realm; an edge equations module configured to derive edge equations of each triangle; and a bound computation module configured to calculate a bound on bits used for each edge of each triangle, and identify an edge bound having a maximal value for each triangle.
