1. A device, comprising: hardware circuitry 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; hardware circuitry comprising a translation module configured to translate each triangle from the three-dimensional realm to the two-dimensional realm; hardware circuitry comprising an edge equations module configured to derive edge equations of each triangle; and hardware circuitry comprising 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, wherein the bound computation module is further configured to determine whether the maximal edge bound value for each triangle is less than or equal to a given bit operation threshold.
