Abstract:
A computer software program for estimating rendering times in a graphics system embodied on a carrier medium, wherein said software program is configured to estimate performance for a graphics system for polygon rendering, wherein said software program comprises a plurality of instructions configured to:calculate a rendering time for a set of graphics data; and, if the rendering time exceeds that specified by a predetermined minimum frame rate, thendetermine whether the graphics data is polygon overhead limited or pixel fill limited, andchange rendering parameters accordingly to achieve said predetermined minimum frame rate;wherein said set of graphics data comprises a plurality of general objects, wherein each general object comprises a plurality of object variants, wherein each object variant comprises a plurality of polygons and rendering attributes;wherein said plurality of instructions are further configured to calculate a cumulative probability density distribution f(a) for at least one of the object variants, wherein f(a) is the probability of a randomly chosen polygon within the object variant having an area a or less.
