Simple simulation I have made in RF, meshed in RF, than rendered with 3 different renderers: Arion from RandomControll guys, Maxwell from NextLimit, and iRay from MentalImages/nVidia. Purpose of that was a simple test, in what stage is a development of unbiased* renderers. Also I wanted to test GPU rendering pretty extensevly.
I promise to make MOF video from that experiment in couple of following days. But for now please check out video tab (left to that description tab).
edit: MOF is availibe under Blog menu :)
Have fun watching.
