View Full Version : IO9: Disney's new Revolutionary Rendering Technique

"An animation studio can spend days rendering a scene that features water, smoke and other substances that affect light (and its simulation) in complex ways. Now, a team led by Disney Research Zürich has developed a computational algorithm that can reduce rendering times for such scenes by a factor of up to 1,000."

"... a team led by Disney Research scientist Wojciech Jarosz has developed a method called "joint importance sampling" that efficiently identifies which paths of light are most likely to contribute to what the camera actually sees. As its name suggests, the algorithm helps sort out which paths are important to include when rendering the final scene, and which can be excluded. The researchers will present their findings this week at the this year's ACM SIGGRAPH conference in Hong Kong.":

hui...interesting, thanks for the link

I wonder how much differs from the MIS that PRMan, VRay and Arnold already have in the sampling algorithm.
