Description:

Fraqtive is an open source, multi-platform generator of the Mandelbrot family fractals. It uses very fast algorithms supporting SSE2 and multi-core processors. It generates high quality anti-aliased images and renders 3D scenes using OpenGL. It allows real-time navigation and dynamic generation of the Julia fractal preview.

Last changelog:

14 years ago

0.4.6 (2012-12-04)

In this version it is possible to generate a series of images with increasing zoom level and optional rotation. This makes it possible to create very nice looking animations.

0.4.5 (2009-12-18)

This release adds the possibility to generate fractal images of arbitrary size. It also fixes some minor bugs and introduces an improved Windows installer.

0.4.4 (2008-07-28)

This release adds some minor improvements of the user interface.

0.4.3 (2008-05-12)

In this release two animation modes were added: color scrolling and mesh rotation. A few problems with Qt 4.4 were solved and some bugs were fixed making it a stable and feature-rich release.

0.4.2 (2008-04-29)

This release adds only one, but very interesting feature: rendering the fractal surface as a 3D mesh, using the OpenGL library for hardware-accelerated performance. It's possible to adjust the mesh resolution and various parameters of the view. The rendered image can also be saved or copied to clipboard.

0.4.1 (2008-04-14)

The new features in this version are: loading and saving bookmarks and color presets, full screen mode and copying and saving fractal images. This release also fixes a crash occurring on multi-core processors and some compilation problems.

0.4.0 (2008-03-25)

A new version of Fraqtive is available. It has a completely new generator engine with support for SSE2, multi-core processors, different variants of fractals and many optimizations for almost real-time user experience. Also the user interface has been completely redesigned and rewritten using Qt4 to make Fraqtive available for both Linux and Windows platforms.

Thank you for the application! Thank you. it is really great. I think the rendering engine should be implemented into KDE-core to render the fractall wallpaper, which is horrible (slow). This application renders very very fast. It is the spirit of free applications to cooperate - I think it would be great to include it. This is just much much better implementatin :) Why double-triple-quadrupple the efforts and not integrate the best, so everyone can use it and make it even better? Sorry this is little rant, because this application is just great so it would be cool if the whole KDE benefited from it :-)

Thanks again

Thanks! Just one note: the 0.4.x versions of Fraqtive require Qt 4.3 or newer and no longer depend on KDE. I forgot to update the "Depends on" field in the description :).

This is a great app, thanks! Though there's one thing I'm missing: some fractal programs has an anti-aliasing feature, which not only makes the fractals look nicer but also makes them more distinct. In example Gnofract 4D does this, and those small shapes looks much clearer. Could such a feature be added to Fraqtive also?

That's a good idea, but it would be quite difficult to implement because the fractal generator works progressively. On the other hand, anti-aliasing could be done in the end, as an additional step. I'll try this and update the program if I get some reasonable results. Thanks for the idea.

Hi,
Fraqtive is really impressive.

Do you have something like a list of features you plan to implement ? Or do you consider the programm as finished ?
- Is there a place to report bugs/wishes or talk about fraqtive ?
- Could one save/bookmark fractals parameters ?
-Could one imagine a kind of krita plugin to make use of its layers capabilities ?
- Could deep zooming be compatible with your fast drawing algorithms ?
- why is there a limit to ca 4000x4000 png ?
I am just getting very curious I know. ;-)

again thank you for your app.

Thanks for the interest in this application.

Yes, I'm going to continue development of Fraqtive and also put it into the KDE SVN repository so that more people could contribute. There is a place for comments, bug reports and feature request on my homepage:

http://zeus.polsl.gliwice.pl/~mimec/index.php?id=fraqtive

Here's a short list of answers:
saving/bookmarking - to be done
integration with other KDE application - maybe, if someone has a good idea how to do it
deep zooming - not sure what do you mean
the 4000x4000 limit - will be removed

4000x4000 to go away ! that is great news.

I am very happy too, to read you are still working on the app and especially putting it on kde svn repository. :-)

I don't know either how to integrate with kde/krita in order to get more functionality. My idea is about implementing something like http://www.ultrafractal.com/features.html#layers using krita. I will ask the krita guys how they would do that (I don't claim I will do it :-( ).

deep zooming - not sure what do you mean. It is about arbitray precision calculation http://spanky.triumf.ca/www/fractint/deep_zoom.html (very slow, but allow to see "new fractal worlds")

happy day.

Hey this tool really takes fractal exploration to another level. I just noticed that it seems that everytime you have a "star" pattern in the Mandelbrot set, with branches meeting at some point, the number of branches is prime. I found points with 5,7,11 and 13 branches meeting. For example, here's a place where 13 branches meet :

X coordinate : -0.728392417954
Y coordinate : 0.240980033161
Zoom magnitude : 4.51563

Can anyone point me to a mathematical explanation for that ? Is that a known theorem ?

I have also found places with 10 or 27 branches meeting

I spent a lot of time playing with this program and always found something amazing. Anyway, I think that the question *why* does it look the way it looks, is much more philosophical than mathemathical :).

I've been waiting for this for a long time ! This is an excellent application, and should definitely go into KDE !

Many kudos to the author !

Please join the SVN Repository of KDE with your app. It has its place in KDE Edu, or KDE Graphics!!!!

Very very cool app.

I really like this app. A little KDE-ification (adding the KDE file dialog etc.) would make it even better, though. Any way: good job.
