Right now I’m in Milano (at a Generative Art conference actually), but when I get home, I’ll add a blog post with an overview of the different GPU implementations. As always, I think your implementation looks very impressive.

I don't think POV-ray allows true conditionals in the internal functional language - so I guess you suggest unrolling the 'while'-loop a fixed number of iterations using pre-processor loops? I have a feeling this will be somewhat slow, compared to the compiled-in version :-) But thanks for sharing your implementation! Hi Abram,

I added my own userdefined function in C++ to do it but you could easily define it using their own function language. Especially if you unroll about 8 iterations into 1 expression ;) otherwise check out POVRay related experiment and explore the mandelbulb on your own! http://softwareprocess.us/index.cgi/Mandelbulb Hi,
