After the impressive and awe-inspiring videos of Minecraft rendered in real-time with the Brigade path tracer (1, 2, 3 and 4), here's a pretty neat day/night cycle animation of a Minecraft level rendered with Octane, which looks completely real and kind of resembles a LEGO world: http://www.youtube.com/watch?v=vCC6Bczi2x0
With a couple of ultrahigh-end GPUs, I think the daylight parts in this animation can be path traced in real-time with very good quality, even though all surfaces are glossy, because almost all of the lighting comes from a skylight. The following video demonstrates the extreme speed with which a completely glossy benchmark scene (the Death Star trench from Star Wars) converges in Octane on 2x GTX 460 under different lighting conditions: http://www.youtube.com/watch?v=uHY90epFf2g. After having messed around with the Brigade path tracer for countless hours on a laptop with 8600M GT and still getting pretty good results in real-time, I'm convinced that Minecraft levels will soon be playable in photoreal quality on high-end hardware. Once that goal is reached, it's pretty easy to imagine what's going to come next.
