ABSTRACT:
In a method of polygon rendering, the coordinate and color spans of each polygon triangle are evaluated whether they are above or equal to a predetermined threshold value. A first bit resolution is applied to the polygon rendering, when the coordinate and color spans are above or equal to the predetermined threshold value. A second bit resolution lower than the first bit resolution is applied to the polygon rendering, when the coordinate and color spans are below the predetermined threshold value.
