Welcome to Fractal Forums

Mandelbulber 0.991 - for Linux x86, Linux x64 and Win32

Open source program (GNU GPL) for rendering photo-realistic 3D fractals

Free download: http://sourceforge.net/projects/mandelbulber/

Website: http://sites.google.com/site/mandelbulber/

New features in version 0.991:

- fixed problem with decreased quality of images  (the problem was described here: http://www.fractalforums.com/mandelbulber/mandelbulber-0-98/msg28877/#msg28877). Added "smoothness" parameter, which is responsible for surface smoothness (calculation accuracy of normal vectors)

Before first run please use install script

Question: the "Smoothness" is set by default as value 1. Very cool feature ofcourse :) but when using that, fractals made with previous versions of Mandelbulber are all too smooth. Thought if I set it to 0 it would mean "smoothness off" but that is not the case. So, is there a value that equals the kind of smoothness previous versions had? I know it has to be somewhere between 1 and 0 but can't find the good value.

Thanx!!

Smoothness = 1 gives the same smoothness level like it was in Mandelbulber 0.97.

Generally there are two parameters which have influence on fractal smoothness. First is "Detal level" which changes smoothness of fractal shape (changes DE threshold). Second (this new) changes roughness level of surface. 1.0 is a standard value. Higher value (e.g 3.0) eliminates noise on surface (but too high value could give weird effects). Lower value (0.1) on some types of fractals makes some detail more visible or produce some kind of noise (especially visible on rotated Mandelboxes). Never put zero value because surface shading will not work at all.

Ahhhh ok! I have been using Mandelbulber since version 0.98 so that's why it looks different for me. Thanx for the explanation!

maaany thanks!!! :embarrass:

mandelbulber on mac osx  ;D

Cool. Could you share the binary or build process you used?

I second that request - plain Xcode project as a complete compressed file would be nice ;)

Or, is that done using Crossover/Wine/Parallels ?

I'm running a little animation with mandelbulber on mac..I think is FAST!
the installation is just a little bit tricky but not so bad.. :)
the steps are:
1-install x11
2-install macports*
3-download the code from sourceforge (googlecode's make-code does not work using cmake on mac); use the linux-version
4-install the libraries using macports (see readme file for libraries's names)**
5-remove the dot from  './mandelbulber' inside c++ code ***
6-compile from terminal > make all/etc.. inside makefiles's folder (same procedure from linux)
7-install from terminal or from installer; or just copy all the various setting files inside a folder named 'mandelbulber' inside your user-folder with all your settings will be created
8-you can move mandelbulber's program created for step 6 where you want
9-mandelbulber is now ready; just click-it or from terminal type 'mandelbulber'
10-have fun!

all the many libraries created for step 4 are located inside opt/local/lib


*installing macports; the easiest way is to download the .dmg file from http://distfiles.macports.org/MacPorts/ after that run from terminal
  sudo port selfupdate

* *so from terminal:
  sudo port install gtk2
  sudo port install libsndfile
etc.. (see readme file from sourceforge for dependencies)

***inside makefile (eventually) change
  -o"mandelbulber"
mine is
  -o 'mandelbulber'
