Fantasy Lab releases Radium SDK
Fantasy Lab, the game development studio started by Mike Bunnell (formerly of NVIDIA), has updated their website with information about their new real-time global illumination SDK called Radium. You’ll remember Fantasy Lab as the company that released the Rhinork GI demo and announced the game Danger Planet (covered here). The description boasts infinite bounces of light. Assuming that they are using the same disc-based transfer approached used in Bunnell’s GPU Gems 2 article (also check out the recent Pixar paper Point-Based Approximate Color Bleeding), I think this means that any number of bounces can be calculated as each bounce is an iteration in that algorithm. I’d definitely like to hear more details but I suppose that is unlikely to happen as they are trying to make a living 🙂

I think Bunnell said in a interview, that he did quite some changes to the underlying technology:
“There are siginificant differences between what the engine can do and the chapters I wrote for GPU Gems. My GI technique works with normal and displacment surfaces, it supports specular material properties, and it does not require multiple passes like the ambient occlusion/indirect lighting technique. My new subd code is much more efficient with displacement mapped surfaces and it supports quads and triangles, not just quads. “

Would you happen to have a link?

well there’s that(and geomerics) !
There is also this company called Sunfish Studio that promises a renderer that can render any geometry (splines,subD’s ,you name it!) with zero-aliasing. Based on a new mathematical background.

P.S. The Michael Bunnell interview was from a forum post if I recall correctly. Oh and I cannot even begin to tell you how awesome the Froblins are.

According to the patent of that company, their renderer is based on interval arithmetic.

I think they’re using precomputed lightmaps with trinary basis interpolation.

[…] blog before, and it is an interesting example of GPU-oriented global illumination. I just read (on the Level of Detail blog) that Bunnell’s company, Fantasy Lab, is now selling an SDK incorporating an advanced version […]

There’s some more info about their GI algorithm in this thread:

It seems that they don’t use any kind of precomputation for the GI. Judging from the video linked in the thread, the results are amazing!
