Details:
This image of Sponza was rendered with a home-made ray tracer, that renders the 76k triangle soup of Sponza in less than a second, with adaptive supersampling and a rather odd hdr effect. Obviously, I am not an artist, so it's just the tech that I wanted to show. :) Sponza is a great set for this kind of research, so a big -thanks!- for making it available.
