No idea, maybe because I compiled the libraries it uses, SDL, libpng and zlib statically to not depend on OS? g++ switches are: -O2 -fopenmp

Completely rewritten the program to get all the variants in one single program. Also made the visualization thread independent of the calculation. Now I'm experimenting with faster methods for deem zooms, like for example Metropolis-Hastings. When this is finished I will put the new version online.

New version is online! : http://sites.google.com/site/buddhabrotmt/-Unified version with switching between different buddhabrot types and between single layer and RGB mode. -Initial version of Metropolis-Hastings for faster rendering in deep zooms, seems to be working ok already: --> switch to type 3 buddhabrot with =

yeah I know, easiest solution is to switch in windows, I think. There is no real connection between the letter and the function, it's more based on the topology of the keys. I think I will make an buildin help that when you toggle a key, it will display the functionality of that key instead of executing the function itself. The help on the website is outdated, doesn't include the RGB functionality yet.

A few question : - Are you planning to opensource it ? - do you use the Metropolis-Hastings Algorithm for deep zooming ? i'm planning to try to implement this algorithm in my buddhabrot fortran renderer, but i don't understand all the maths behind it. i need to see code to understand it, not formula

1- Are you planning to opensource it ? 2- do you use the Metropolis-Hastings Algorithm for deep zooming ? 1 At the moment, no. 2 Yes I do, but it's quite crude now, it works but for example the code here is more advanced: http://www.steckles.com/buddha/I wonder what the effects are on the final render when you compare it with a normal render, it now clearly is different when rendering the whole buddha.

Updated version BuddhaBrotMT-2010-06-04.zip: - 16-bit png support (switch with 'b') - you can change number of calculation threads with 'i' and 'o' - no "not responding" caption during write to png - should now properly work on computers with less than 8 virtual cores https://sites.google.com/site/buddhabrotmt/

Updated version BuddhaBrotMT-2010-06-09.zip: - save and load status and parameters to disk with F9-F12 So now you can save a long render to disk and reload it to continue were you last saved. https://sites.google.com/site/buddhabrotmt/

Hi, any chance of building the linux version against libdirectfb-1.4.5... or releasing it as open source
