Implementation of Bidirectional Ray Tracing Algorithm

Le résumé fourni par la source

: This paper examines existing bidirectional ray tracing algorithms and the bottlenecks and possible benefits compared to backward tracing methods. The results of the implementation of one algorithm is provided. The article addresses the problems in the implementation of this a system including accurate probability calculation and efficient ray generation. Keywords: Computer graphics, ray tracing, Monte Carlo methods, bidirectional ray tracing 1. Introduction The aim of computer graphics is the solution of the rendering equation [Szir95]. It causes many difficulties, that this equation contains the function to estimate on both sides. Also, the function to integrate has bad properties. The light sources in the scene are usually small, therefore most light within the scene usually comes from a small area. In many cases, the surfaces are specular, and the light is reflected into a small area as well. Monte Carlo and quasi Monte Carlo [Shri65] ray tracing methods are powerful tools to so...
