Web1 de nov. de 2016 · In this work we present a hierarchical factorization (HF) technique for radiosity calculations. This technique implements a divide-and-conquer strategy based on the calculation of multiple singular value decomposition (SVD). In addition, the sorting of rows/columns of the matrix RF by similarity is exploited to speed-up the technique.
