Ray tracing is a straightforward and powerful image synthesis technique but usually requires many rays per pixel to eliminate the aliasing or noise in the final image. However, not all the pixels in the image require the same quantity of rays. In this paper we introduce new measures for supersampling refinement criteria, based on colour and geometry. These measures use the entropy, one of the most relevant Information Theory concepts. All the new measures are compared with other classic contrast measures
