High Quality Final Gathering for Hierarchical Monte Carlo Radiosity for General Environments

Abstract

Aiming at rendering high quality images robustly for general environments with simple algorithms, we use a two-pass method that accounts for the global illumination. In this paper we present the integration of a new gathering procedure in the rendering pass, that uses the approximate results obtained by a particle tracing method, an extension of the Hierarchical Monte Carlo Radiosity (HMCR) algorithm. Results from our implementation demonstrate the efficient generation of high quality images using the technique presented herein.
