Construction of the Underworld by beason Construction of the Underworld by beason
Peering through snowflake ridges.
Named after song by The Synthetic Dream Foundation.

Inspired by Rise [link]
:worship: , which caused me much "wtf?? how did you do that?" for a long time. I believe this uses pretty much the same technique.

RIFS shape by Cabrelli et al. Intersection algorithm by John C. Hart. As the image is symmetric I only rendered half of it, at 4X res in 31 hours on a 2.6GHz quad core CPU with Pane, then mirrored with imagemagick and then gimp for levels and watermark. Lighting is ambient white light with lambertian reflection and unbiased path tracing.

rise is simply a few sierpinski tetrahedra arranged in the shape of an icosahedron :)

~1.5 days on a quadcore (core i7 920?), sounds about right! gi + fractals is painful eh?

Yeah, but I hadn't seen that kind of detail before with GI since usually all the geometry is baked into some kind of acceleration structure. Using an implicit acceleration structure was a new idea to me, although I had seen similar ideas, like for example, sphereflakes.

No i7 yet, I wish. My Q6600 is finally getting some use though, and this was definitely pushing it! It's painful if the render is still going 16+ hours, i.e. after I sleep and work, which these sometimes need to smooth out the noise.
