Arbitrary Importance Functions for Metropolis Light Transport
We present a generalization of the scalar importance function employed by Metropolis Light Transport (MLT) and related Markov chain rendering algorithms. Although MLT is known for its user-designable mutation rules, we demonstrate that its scalar contribution function is similarly programmable in an unbiased manner. Normally, MLT samples light paths with a tendency proportional to their brightn...
متن کاملA Practical Introduction to Metropolis Light Transport
Most descriptions of Metropolis Light Transport (MLT) currently in the literature focus on theoretical completeness rather than readability. In fact, the core concepts of MLT are not difficult to understand, but available descriptions of these concepts tend to be steeped in statistical terminology and light transport jargon. In this paper, we take a different approach, concentrating on giving a...
متن کاملMetropolis Light Transport for Participating Media
In this paper we show how Metropolis Light Transport can be extended both in the underlying theoretical framework and the algorithmic implementation to incorporate volumetric scattering. We present a generalization of the path integral formulation that handles anisotropic scattering in non-homogeneous media. Based on this framework we introduce a new mutation strategy that is specifically desig...
متن کاملA variance analysis of the Metropolis Light Transport algorithm
The Metropolis Light Transport algorithm is a variant of the classic Metropolis method used in statistical physics. A variance analysis of the Metropolis Light Transport algorithm is presented that bounds its variance in terms of the number of paths used and the intrinsic correlation between samples. It is shown that the variance of a pixel is where is the number of samples for the entire image...
متن کاملSimple and Robust Mutation Strategy for Metropolis Light Transport Algorithm
The paper presents a new mutation strategy for the Metropolis light transport algorithm, which works in the space of uniform random numbers used to build up paths. Thus instead of mutating directly in the path space, mutations are realized in the infinite dimensional unit cube of pseudo-random numbers and these points are transformed to the path space according to BRDF sampling, light source sa...
