That's interesting... Wish I knew it when I talked to them at FMX. I wonder how popular it is for studios to pirate software.

 

Edit: I think there's more to this story. Read the comments.

Hmm... no love for OSX and Linux from Oculus Rift team this year. Sorry Marty... :D

Our development for OS X and Linux has been paused in order to focus on delivering a high quality consumer-level VR experience at launch across hardware, software, and content on Windows. We want to get back to development for OS X and Linux but we don’t have a timeline.

"We introduce gradient-domain rendering for Monte Carlo image synthesis. While previous gradient-domain Metropolis Light Transport sought to distribute more samples in areas of high gradients, we show, in contrast, that estimating image gradients is also possible using standard (non-Metropolis) Monte Carlo algorithms, and furthermore, that even without changing the sample distribution, this often leads to significant error reduction. This broadens the applicability of gradient rendering considerably. To gain insight into the conditions under which gradient-domain sampling is beneficial, we present a frequency analysis that compares Monte Carlo sampling of gradients followed by Poisson reconstruction to traditional Monte Carlo sampling. Finally, we describe Gradient-Domain Path Tracing (G-PT), a relatively simple modification of the standard path tracing algorithm that can yield far superior results."

Very cool usage explanation of those ridiculously fast L1, L2, L3 CPU caches- Let's access our data with rows not columns please!

This was already an optimization since at least the Pentium Pro where I got a huge improvement in '96 by simply changing the (general) image convolution filter in PhotoPaint at the time to run over pixels horizontally instead of vertically(!).
