Temporal radiosity method for 3D-scenes of arbitrary detailization
Abstract:
In this paper, we propose an approach for calculating global illumination by the radiosity method that allows achieving high performance for a large number of patches involved in the calculations. Two key ideas of the proposed approach are the creation of proxy geometry based on axis-aligned virtual patches and the method of temporal radiosity, which uses the interpretation of form-factors in terms of probabilities. The combination of the proposed methods makes it possible to obtain a rapid update of global illumination for light sources changing their positions with image quality close to the naive radiosity method.
