Hi,
It's basically just a render farm with really fast turnaround :-). Nothing particularly amazing about it. AFAICT the whole frame is rendered on the servers and then the frame is sent back to the laptop to be displayed. The raytracing aspect isn't that spectacular really, raytracing is known to be something which lends itself well to being done in parallel. It sounds like the rig in question used four 32 core Knight's Ferry cards, with each core running 4 threads, for a total of 512 threads. It's not wonder it can do what it does :-). Just like the other demo someone posted, the ability of the software to work effectively with so many threads is the most impressive thing.
I have to say the visuals are pretty cheesy looking, like your classic raytracing demo from back in the day, just faster :-). It would be impressive if they had more realistic lighting effects and materials.
Regards,
Jo
