Useful Markov Chain Monte Carlo Papers to apply to Graphics

Here are some Useful Markov Chain Monte Carlo papers that I have come across when surfing the web, that I think have use in Metropolis Light Transport(MLT) Implementations A general construction for parallelizing Metropolis−Hastings This is a paper for augmenting metropolis sampling with multiple pr...

Generalizing the Golden Ratio Sequence to Higher Dimensions

I am trying to figure out a way to generalize the golden ratio sequence to higher dimensions in a way that is extensible(does not make any assumption about the amount of samples that are going to taken), as well as scaling well to 6 or more dimensions. The golden ratio sequence is desirable because ...

Re: Light Ray Differentials

First of all a LOD system like psychopath involves testing against the bounding box before intersecting the micropolygons. so one way of approximating the screen space footprint in bidirectional path tracing would be to first trace an approximate path from the light source treating the patch boundin...

Bidirectional LOD

I would like to find out how to estimate the footprint of a path in screen space that originates from the light source. The reason i am interested in this is so that I can implement micropolygon(in spirit of psychopath) bidirectional path tracing. I am aware that it's a nontrivial thing to do. The p...
