By using the principles of physical light propagation, images that are indistin-guishable from real photographs can be generated. This computation, however, is avery time-consuming task. When simulating the real behavior of light, individual imagescan take hours to be of sufficient quality. For this reason movie production has reliedon artist driven methods to generate life-like images. Only recently there has been aconvergence of techniques from physically based simulation and movie production thatallowed the use of these techniques in a production environment. In this thesis we advo-cate this convergence and develop novel algorithms to solve the problems of computinghigh quality photo-realistic images for complex scenes.
