....smoothness in the target function. The general mathematical scheme and its highly efficient implementation are illustrated for image generation by ray tracing, yielding new and much faster image synthesis algorithms. 1 Introduction Image synthesis usually is performed on a pixel by pixel basis [CPC84] [CCC87] HA90] using variance reduced Monte Carlo integration for antialiasing. In [Mit96] the convergence rate of the Monte Carlo method with N samples per pixel was shown to be of the order O(N 2d ) where d is the dimension of the integration domain. This is also the rate obtained by ....
....filtering and tone mapping. the two dimensional area P of a pixel. Including depth of field and motion blur, we get d : dim D = 5 by additionally integrating over lens area and aperture 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 ....

....explicit inversive generator is taken from [Nie92a] These two pseudo random number generators approximate discrepancy of order of random numbers, whereas the Halton and Hammersley points have a discrepancy of order , respectively. In addition we show the results for jittered sampling [CPC84] where, due to construction, only the results for those N are shown, where N = # N# . 3.2.1. Experiment 1. The first experiment uses (3.2) for the approximation of the form factors in an empty unit cube. Here the density is separable, and we have D # (p, CN ) D # (PN ) due to remark ....

....the CoC s ( circle of confusion ) effect. This partial occlusion can cause blurry backgrounds to affect sharp foreground objects. Potmesil and Chakravarty s method is not accurate in many cases. Thus there were many attempts to create a fast and accurate DOF method. Cook, Porter, and Carpenter [Coo84a] implemented a distributed ray tracing algorithm. Haeberli and Akeley [Hae90a] created an accumulation buffer to provide hardware anti aliasing, and it can also be used for DOF effects. Shinya [Shi94a] adapted the distributed ray tracing idea and converted it into a postfiltering process. Fearing ....
