.... could be applied to image warping where specular e#ects are prominent, as in the work of Lischinski and Rappoport [19] Finally, the benefit of analytical path perturbation over random perturbation may provide a new low variance mutation strategy in the context of metropolis light transport [28]. Acknowledgments The authors wish to thank Anil Hirani and Al Barr for many valuable discussions, Don Mitchell and Pat Hanrahan for their patience in answering our questions, and Mark Meyer and the anonymous reviewers for their helpful comments.

....Keywords: interactive rendering and shading, texture mapping, reflection mapping, image based rendering. 1 INTRODUCTION Offline rendering algorithms have to a great extent conquered physically accurate photo realism and complex synthetic shading. A result of over twenty years of research [1, 4, 5, 12, 15, 19, 21, 23], these techniques all solve the lighting or rendering equation [16] in some manner. The outstanding rendering challenge now becomes how to increase the performance of sophisticated shading algorithms without losing the advancements made in quality. Specifically, we are interested in interactive ....

....time. Further adding direct illumination by area light sources or daylight simulation, the dimension becomes 7 [CPC84] The dimension even can get infinite when using random walk approaches to simulate global illumination like bidirectional path tracing or the Metropolis light transport algorithm [VG97], where D becomes the infinite dimensional path space. 2.1 Integro Approximation The pixels (L k ) k=0 of a scanline also can be considered as samples of a continuous function L(x) L S (x, t) dt C( 0, 1] where L is an integral dependent on the parameter x and fulfils the ....

....the photon distribution of the importance driven photon map generation. Due to energy bleeding [KW00] the importance shines through the walls and photons are deposited in areas of actually no importance, i.e. behind the wall. This could be avoided by using the Metropolis light transport algorithm [VG97, PKK00] to deposit photons by the techniques of the previous sections. This however indicates that using Metropolis light transport algorithm alone is more sophisticated. 3 Efficient Direct Illumination Computation The efficient computation of direct illumination still is a core problem of ....
....to the bidirectional path tracing algorithm [LW93, VG94, VG95] where it is used to save shadow or connection rays. Then the photon map would serve as a point approximation of the radiance like in [Kel97] This would also improve the bidirectional mutations of the Metropolis light transport [VG97] algorithm. 4 Conclusion We presented new importance sampling techniques for the photon map, which result in a reduced memory footprint and increased rendering efficiency. Our importance driven generation of the photon map controls the deposition, which is more efficient than controlling the ....

....sequence by an other sequence which smoother but still results in the correct reflected radiance when averaging takes place. Two techniques are presented, the first is based on the main part separation [6] and the second applies random acceptance and rejec tion similar to Metropolis Sampling [8]. The first method separates the constant main part of the reflected radiance, which is replaced by its average. Let us store the directional aver age of the reflected radiance in variable L 4 (n) in each patch computed as = 1 r(m) a(com) m=l where a(co ) is the albedo of the material. Note ....

....set of rays has been found that reach a representation of the receiver position (see Figure 10) Figure 10: Ray tracing method. Monte Carlo path tracing methods consider randomly generated paths from the source to the receiver [63] For instance, the Metropolis Light Transport algorithm [125] generates a sequence of light transport paths by randomly mutating a single current path by adding, deleting, or replacing vertices. Mutated paths are 9 accepted according to probabilities based on the estimated contribution they make to the solution. As contributing paths are found, they are ....
