Ray tracing usually needs supersampling to reduce aliasing or noise in the final image. Not all the pixels in the image require the same quantity of rays, thus adaptive supersampling is implemented by adaptive subdivision of the sampling region, resulting in a refinement tree. We present here a theoretically sound adaptive supersampling method based on… (More)
