Mathematical Basics of Monte Carlo Rendering Algorithms
The high computational costs associated with global illumination in the field of computer graphics call for effective ways of handling complicated integrals and sums. This paper offers an overview of Monte Carlo methods, stochastic methods of approximating such constructs. Starting with the necessary mathematical basis for understanding Monte Carlo, the paper continues with a survey of sampling...
متن کاملQuantum Monte Carlo Simulations: Algorithms, Limitations and Applications
A survey is given of Quantum Monte Carlo methods currently used to simulate quantum lattice models. The formalisms employed to construct the simulation algorithms are sketched. The origin of fundamental (minus sign) problems which limit the applicability of the Quantum Monte Carlo approach is shown to be a generic feature of the formalisms used to devise the simulation algorithms. A brief overv...
متن کاملComplexity of Monte Carlo and deterministic dose-calculation methods.
Grid-based deterministic dose-calculation methods for radiotherapy planning require the use of six-dimensional phase space grids. Because of the large number of phase space dimensions, a growing number of medical physicists appear to believe that grid-based deterministic dose-calculation methods are not competitive with Monte Carlo methods. We argue that this conclusion may be premature. Our re...
متن کاملNovel Monte Carlo algorithms and their applications
We describe a generalized scheme for the probability-changing cluster (PCC) algorithm, based on the study of the finite-size scaling property of the correlation ratio, the ratio of the correlation functions with different distances. We apply this generalized PCC algorithm to the two-dimensional 6-state clock model. We also discuss the combination of the cluster algorithm and the extended ensemb...
متن کاملMacro Monte Carlo for dose calculation of proton beams.
Although the Monte Carlo (MC) method allows accurate dose calculation for proton radiotherapy, its usage is limited due to long computing time. In order to gain efficiency, a new macro MC (MMC) technique for proton dose calculations has been developed. The basic principle of the MMC transport is a local to global MC approach. The local simulations using GEANT4 consist of mono-energetic proton p...
