An Integral geometry based method for fast form-factor computation

摘要

Monte Carlo techniques have been widely used in rendering algorithms for local integration. For example, to\udcompute the contribution of a patch to the luminance of another. In the present paper we propose an\udalgorithm based on Integral geometry where Monte Carlo is applied globally. We give some results of the\udimplementation to validate the proposition and we study the error of the technique, as well as its complexity.
