Hi, last week I downloaded and installed this fantastic software for the first time, the latest version I think (mandelbulber2-win64-2.06-standalone.zip).  Great fun!  But I am trying to understand the meanings of the various settings in the .fract files supplied.  I can open an example project in the software and identify some of the parameter settings in the *.fract file for the project, but others remain a mystery.  I was able to find a enum of the formula types (formula_2 8; for example is the mandelbox formula and would be found in the fractal formula #2 tab).  Other things I am not so sure of...some I can find that look like they would take a single value, smoothness for example, but the parameter setting has two values,  : smoothness 0, 001;  or gamma 0,5; 

Is there any place where one can find an interpretation / clarification of the various parameters in the *.fract files?  The online docs must be for an older version as the UI screenshots look considerably different from what I see in the version I have.

many thanks,

Phil J.

Hi Phil, welcome to the forum.
the "," is a european like decimal separator, so a gamma 0,5 is actually a "half" gamma.  grin

the information inside the fract files is quite condensed and give not much insight.
If you want to learn what the parameters mean i would recommend you use the program, hover over the parameters and see the tooltips. Tweak the parameters around to see the effect they make.

Anyway if you are interested in scripting for the program there is also a big cli, just invoke the program with
mandelbulber --help
to see all kinds of command line parameters, to get all possible fract parameters, invoke with
mandelbulber -L # this will give you a huge list

cheers!

Thanks, Zebastian, I appreciate the info!  Especially the fact that (0,5 == 0.5) in my Texian way of thinking.

There is quite a bit to learn about this software, all very fascinating.  The example projects are all great. 

The gallery at the mandelbulb site (http://www.mandelbulber.com/gallery_page1.php) has some wonderful art.
Those that indicate that the fractal parameters are available are mostly for much earlier versions, 1.06 and so on - is there any way to translate those into the proper format for version 2.06?

thanks!

Hi Phil,

From memory, converting old .fract files is do-able, except for some issues related to fog and colour.  The safe way is to get them working in V1.21 (that is load in V1.21 and see if there are any major problems), then in V2.06 use, File -  Import settings from old Mandelbulber (v1.21). This deals with a change in z axis direction that happened with the update from V1.21 to V2.01.  Also I think skipping the middle V1.21 step is likely to also work in most, if not all, cases.   Give it a try and report back smiley

Clarifying, I think the  .fract file only shows parameters that have changed from the parameter default settings. If you change all default settings you could then see them  all in the .fract file.


Here is  a section of fractal_list.hpp from dev V2.07, I think numbers 0 to 58 are what is in V2.06. (not all work).   A lot of the formula related source code files are reasonable easy to understand. In V2.07 each formula UI will have "info",  including  a copy of the formula code

Thought I would test the first one, it was from Taurus using Mandelbulber V1.06. I  copied parameters into a text file, named it bla.fract,  used File -  Import settings from old Mandelbulber (v1.21). and got a black screen  shocked

Color was the problem, clicked on "generate new random palette"  and got attached image. So it works OK with that one.

Thanks,

I was able to get the Dyson Sphere to render same as you, by  generating a new random palette.  Several others I tried from the gallery
(Chusak Planitia, reflections within reflections, volumetric light) all gave errors "error:Hybrid fractal can't be converted".

Menger Sponge variation 1  ran but came up blank after changing palette several times.  Coral garden sort of rendered, but nothing like gallery image.
Mirror Balls  rendered such a pixelated image that the structure was barely suggested by the rendition.

Maybe I am doing something wrong?  I did get a number that said invalid header and I had to change to:
Code:
# Mandelbulber settings file
# version 1.0600000000000001
# only modified parameters
[main_parameters]


thanks,

Phil J.

Looks like i tested the easiest to import. grin

Yes the hybrid ones a more difficult to import and requires an understanding of the old .fract files.
 I tried the next one,  Chusak Planitia.

 Firstly I imported into V1.21, I got the white screen problem, solution turn off or reduce basic fog.

Secondly I changed the formula in the .fract file from Formula 12; (old hybrid mode) to Formula 8 (Mbox) and remove all lines that began with "hybrid_". I also turned off slow stuff like reflection, multi ray AO, and reduced the image size by /4. Then used "import setting from old Mandelbulber (v1.21)" to get it into dev V2.07.

Thirdly reinstalled the hybrid parameters and got the shape.

BUT the deltaDE linear did not seem to work as well as with the original h'mmmm??, nor could I get the reflection to work h'mmm???.

Thanks, fascinating!  How did you know to change the now-invalid hybrid formula (12) to the combination of mandelbox(cool, menger sponge(7) and 2 instances of mandelboxVaryScale4D(18) and know which parameters to set on each of these?

The Chusak Planitia .fract versions you posted in this thread did work and gave similar results, it did complain about the random lights intensity and number ,    delta_DE_method, but still rendered.  I thought I'd comment out those lines, but it looks like the # is a mandelbulber directive, not a comment?

thanks,

Phil J.

mclarekin is a age long user of the program, so he is aware of formulas and the changes, especially the cryptic named vonce are sheer knowledge about the program and its use wink my guess

many formulas can be recognized though, and transformations can be recognized as well, e.g. a rotation added at one iteration, but results can vary massively
