Increasing the convergence speed of psysically-based rendering algorithms in computer graphics using frequency-based combined adaptive sampling and adaptive filtering KU Leuven
Physically-based rendering is one of the major research topics in the field of computer graphics. It deals with the generation of photo-realistic images depicting a virtual world. Although research in this field has a history dating back more than 25 years, generating photo-realistic images efficiently is still a problem of major significance. For each pixel in the final image a light transport equation needs to be evaluated, of which the ...
