EDIT UPDATE: FOR THE SAKE OF CLARITY: THIS IS NOT TO SUGGEST THAT YOU NEED A RENDERFARM FOR RENDERING WITH THEA - THE INTENTION IS TO ALLOW USERS TO SEE THE RAW POWER THEY COULD MAKE USE OF IF THEY NEED EXTREME SPEED IN CLEARING THEIR SCENES. Professional Users with deadlines could make use of this service to render 10 views of a scene to provide to their customers - IN THE SAME TIME THEY WOULD NORMALLY PRODUCE ONLY 1!!! Thea is an extremely fast engine with features offered and efficiency comparable to Engines costing MANY TIMES MORE!!! Please read this post with the idea in mind that we are only providing a "test render" for comparing HOW LONG it would take your machine to achieve a s/p (samples per pixel) level of 2000. Samples per pixel related to the relative clarity (in terms of light sampled per pixel) in a rendered image. There is a wikipedia article describing this metric here: http://en.wikipedia.org/wiki/Pixel
I'd love to see some comparisons from other users of Thea - So I ran a test with my renderfarm on the SunPoolCaustics example scene. The only change I made to ANYTHING in the standard scene was to set SuperSampling to "HIGH". I've attached a compilation of the times over the course of 2 hours.
To Participate (so we can all get an idea of the speed at which this scene converges and compare it against specific hardware configurations),
Please open the Scene (located in the file->scenes->examples->sunpoolcaustics), set supersampling to "high" and set max samples to 2000. I hit this (actually a bit over 2012) in 1:53:00 ...
POST YOUR MACHINE SPEC, TIME TO RENDER TO 2000s/p, and a screenshot!
Good Luck - I'm VERY curious to see the variety of speeds out there!
