Please tell me what you think about it. Personally, i rediscover the buddhabrot and it's (for me) the most amazing "2D" fractal.  and a zoom on the little bulb to the left of the center (yes, differents colors and iteration level) :  |

A beauty! Cloudy with a chance of seahorses.  Hint: Go for metropolis-hastings. This will speed up the renders and get rid of the noise quicker. I've got it working in CUDA, but I've got no color yet and I'm still working on the HDR->LDR mapping. |

A new one \o/ Used the gimp to improve contrast (adjusted the histogram manually) Edit : tbh, the histogram adjustment could have been better. but i was in a hurry.   |

Awesome! these make me  ... Respect! The last one reminds me this one. How much time did it take to render? |

Awesome! these make me ... Respect! The last one reminds me this one. How much time did it take to render? heh, thank you It took one full night on my Ion2 Laptop. It was slow you can see some number on the left of the 1st pic, it mean : ~26.000 sample/s 1 sample = 1 thread. 1 thread = fetch a random X/Y point. check and iterate "if in MSet". if not in MSet : iterate and draw orbit. edit : about this one, this page is in my bookmarks, and one of my (multiples) goals is to do better than this. (i love challenges) |

Finally I found a solution how to get my GTX 460 working in my mainboard. It was a simple change in the BIOS settings. Your ION2 has 16 CUDA cores, the GTX 460 has 336 ;-) I will try to run your OpenCL code as well. |

Fantastic, you programmed it in OpenCL! I wonder if it will work under Snow Leopard on my Hackintosh?

i develop using Visual Studio 2010 in C# with .NET Framework4. The code can easily be ported to any platform if you know how to code. the source is here : http://github.com/ker2x/WinBuddhaOpenCLThe openCL code is a huge string in BuddhaCloo.cs, i use "Cloo" for the C# binding which is very understandable without reading the documentation (btw, Cloo is not documented, but the source code is available) Feel free to write your own mac software based on my code |
