writes "Computer-generated images can be a little more realistic — and a lot cheaper to make — with an open-source rendering program created by Cornell graduate student Wenzel Jakob. A major new version of Mitsuba was just released. "What really is new is that Mitsuba implements a group of rendering algorithms that traditionally have been horribly complicated," Jakob said. Together with improvements developed at Cornell University, these can simulate the complex behavior of light traveling through glossy materials such as brushed metal or glass."Link to Original Source
writes "After a two years of internal development and a whopping 5MB source code diff, a completely redesigned version of the Mitsuba renderer was just released to the public.
Mitsuba is a modular physically-based rendering engine which features an interactive preview and many state-of-the art rendering algorithms that can be tweaked and combined in endless ways. One of the highlights of this release is that it includes the first openly available implementation of the original Metropolis Light Transport algorithm that works correctly. The release announcement contains a full listing of all new features. Example scenes, the source, and binaries for all major platforms are provided on the download page."
