hi there,

i am wondering, is there actually a buddhabrot renderer that is use-able !?

i saw some ultrafractal buddhabrots, but the formulas seem not to work anymore ... ;(


how would you render a buddhabrot, if not writing a new program for it ?! cheesy

As far as I know there are none good. Ultra Fractal buddhabrot are somewhat unbuddhistic;)
Original version uses 3 channels, UF implementations 1 channel. They work but are somewhat plain. I f I would implement it, there would be one with 3 channels and using map, but I 'm too tired of engineering, so not now.

I once uploaded a CUDA based buddhabrot to the nvidia forums. I am not sure if that survived the forum migration (they had a security breach and created an entirely new forum - but tried to preserve all postings). The Metropolis-Hastings based renderer allowed for interactive zooming, but was limited by single precision floating point.

here's a thread about these GPU buddhabrots with several contributors.

The forum thread I linked to in my edit contains some code (requires a CUDA capable NVIDIA graphics card). Not sure if it is the latest version.

http://www.fractalforums.com/index.php?action=dlattach;topic=3614.0;attach=2973
and some required DLLs (place these in the Release folder).
http://www.fractalforums.com/index.php?action=dlattach;topic=3614.0;attach=2950

If I remember correctly, in order to zoom you have to draw a rectangle while pressing the left mouse button and then click into it with the right mouse button. Use the space bar to reset the view. The images are rendered like Polaroid photos... slowly wink

There are .bat files to start this in three different coloring modes. Some additional instructions for hot keys are printed into the DOS box.

Source code is included. And I just got this to run on my PC at my workplace.

You might be thinking of William Milberry, user name aluminumstudios.  As far as I can remember, his Buddhabrot rendering software is not something he has released to the public.  Too bad, it creates excellent images.

I find that the Metropolis-Hastings version still takes forever to compute a zoomed image.
I'll stick with my CUDA implementation then wink

I seem to remember a fairly simple one made by Richard Rosenman (who also has an account here so he might be stopping by) that just worked as a photoshop plugin.  As I remember the buddhas were pretty good quality for such a simple plugin. I would recommend looking at it  smiley

Nice images, I will try to create a plugin for Buddhabrots in JWildfire soon. Could be also easily animated then.

Sounds as good news, cos there realyu aren't good user friendly and powerfull implementation of buddhabrot with 3 colours.

I have some ideas, and I will implement my version of buddhabrot in Ultra Fractal and Chaos pro. In UF there are some buddhabrots, but of 1 colour dimension, so pretty boring. Actualy I had few colour methods using buddhabrot like 3 colour channels.
