My problem with these voxel softwares is that they was made to a different task, not 3D fractal visualization, but visualization of oblejects with a smooth/connected surface. In contrast, if you generate fractals, you have a set of points with X,Y,Z coordinates, and the software have to define a continuous surface on them. This is the difficult part of the task.

I also played with voxels before: created .obj files (it has a simple file structure: https://en.wikipedia.org/wiki/Wavefront_.obj_file), represented voxels with cubes, but the preblem was the following: I had only 6 different directions of surfaces. Eg. there were no contrast between neighboring surfaces (resulted "LEGO-style" images):

I'm looking for a software that can create something similar:

Looks interesting.

Yes, that is still a problem with simple voxel editors. I have tried to find better ones but this one seems to be the most practical one to use. It actually has an option to double the number of polygons to make structures a little nicer but since they are made by hand and not by formula and the resolution of them is very low it is just a project just for fun. But I can ask for better rendering options, it is an open source program.

The main "problem" (or feature cheesy ) of 3D fractals that these don't contains poligons, only points. But a voxel software doesn't have to create poligons on a set of points. This is task for a fractal software.

True, it might be umconventional but it is the specific thing I was looking for.

Take a look at my hobby-project, StyrofoamIFS

http://phtolo.se/fractals/index.htm

It only handles IFS fractals but it can create arbitrarily large point-clouds.

Thank you, I will do that once I have my 64bit machine working.

Wow, this IS what we need here! Could you complement this with an import function? I think about a set of points in a .txt file in ASCII format: X; Y; Z coordinates in 3 columns, separated by semicolon or something...

There is a outputformat command for .scene files that creates text-files. (Last in the manual page for .scene files)

Oh, good. And can it read them back?

wow! this is a fascinating gallery (and hobby-tool!!) you have there, phtolo!

Your barnsley fern with the added rotation looks so much like this is the way to 'generate' romanesco! is this that is the difference? fern 2d, romanesco 3d, with added rotation?

does your program has a 'readable formula'? I'd love to see the text/math form of romanesco broccoli!

(hope you don't mind embedding the gif here? I'll remove it if you have to look for bandwidth)

I see your point now, it can't be done now, but I'll look into it, give me a day or two.

Thank you smiley
The fractals are defined using a text editor so they are very much readable.
See here regarding your romanesco related thoughts:

The gif is okay, I have no problems with it. It shows a great example of what the program can do.


Just in general, if other people do have issues with it, please let us know.




Thank you, I will do that once I have my 64bit machine working.
I'm curious, would it be possible to make a 32bit version?

joy I would be really happy with that; I was looking for something similar a long time ago. Cheers!
A 32 bit version would also be useful indeed.

Theres a new version now that can read .xyz files.
I haven't updated the manual yet, but it reads the formats that it can create.
Put the .xyz files in the ifs folder and select them as any .ifs file.

I'll take a look at a 32-bit version tomorrow.
