Re: Topmod!

I love Topmod. Coincidentally, there were some awesome 3D prints of Topmod models at SIGGRAPH this year. They're beautiful objects to actually hold. I think this one uses a plaster-like substrate.

Re: Manifold Exploration: A Markov Chain Monte Carlo techniq

The extended technical report makes for some great reading. I'm particularly impressed at how the authors have unified BDPT, MLT and ERPT into a single abstract framework from which they draw comparisons to their own approach. It includes extending ERPT to handle all light transport which until now ...

Re: Playing with light (a spectral rendering example)

I saw a few examples of this a year or so again. They were done using Fry Render if I remember correctly. http://cs.swan.ac.uk/~csbenjamin/stuff/diff1.jpg http://cs.swan.ac.uk/~csbenjamin/stuff/diff2.jpg http://cs.swan.ac.uk/~csbenjamin/stuff/diff3.jpg http://cs.swan.ac.uk/~csbenjamin/stuff/diff4.jpg

Re: Fireflies in pathtracer

This isn't a perfect fix, but you might be interested in this paper which uses outlier rejection to remove fireflies. It's a sample space filtering technique so you don't get the same smudgy artefacts as with some methods. Also, the energy that's removed by the filtering can be cached and added back...
