Hi all,

It's being over 10 years since I last used Ultrafracta, but it's still a great program. I've started with an easy one, a classic Julia spiral. Tweaks are welcome, I hope you enjoy it.

Hi All,

The January 2017 collection of the parameter files of UF is sent to the cloud.

You can find them at the cloud of Microsoft:!1034&authkey=!ALIZio6ZmgV1aAo&ithint=folder%2ctxt

I first got Ultrafracal in 2010, and at that time I implemented some formulae for showing cubic and higher-degree Juia and Mandelbrot sets. I also formulated the so-called cubic Rudy set, which is, in my opinion, the best cubic analog to the quadratic Mandelbrot set. Like the Mandelbrot set, the Rudy set is in some sense an encyclopedia of the relevant class of Julia sets. It's all explained on

I'd guess this is a slightly technical question. I have an Amazon Web Services account, and was exploring the possiblity of setting up a cloud server to render ultrafractal compositions on - I've just lost the powerful work machine I used to use (with permission) and am looking at alternative solutions.

Has anyone ever done this? Is it even possible? I'm guessing I would have to use a Wind

The drop down menus no longer work. I've re-installed twice to no avail.

They will open but I cannot select or change them. This is for every menu bar and drop down.

I am new to Ultra Fractal and I was wondering. Is there a way to render fractals that do not take long periods of time. I'm wondering if I am doing something wrong. Sometimes rendering a 20 second animated fractal can take me hours.
Anyone have any thoughts or pointers on this subject.
Thanks, John

I have been using Fractal Explorer [now defunct, and I'm kicking myself fro not buying a license to the source years ago when the Russian dude was still responding to e-mail] and I have many [probably about 1k] original fractal formulae that are stuck in that format.

I still have the app, but it only works on 32 bit systems, and I only have one 32 bit computer left.

In some tutorials I'm asked for a (lkm folder) in Ultra Fractal 5 for mac.
Ii've search through the Ultra Fractal 5 file structure and have not found
this folder designation.
I'm not that familiar with UF 5 for mac or windows versions and I'm foundering if the pre-gradients package that come with mac versions is limited.
Are there is any download packages for pre designed gradient for

I am absolutely brand new with this software and am finding the tutorials frustrating in that the images do not seem to coordinate with the views I see in the toolbox section at the right of the screen. The tutorial images seem to be outdated and therefore I can't learn the objective at hand.

I'd like to start with simply modifying a formula. Any help is much appreciated.

I am completely new to Ultra Fractal and would like to create images that can be saved in 16 bit RAW file format. While Ultra Fractal does not do this natively, it appears Ultra Fractal is only using 8 bits per color channel.

Is this correct? Is there a way to use 16 bit color channels? I am actually looking to use the images for heightmaps, but would like 16 bits in a single color channel.

I was a user of coreldraw (with photopaint) X4 and moved to corel X6.
I could import very correctly tif from ultrafractal to corelphotopaint x4.
Now, it is impossible for me to import UF tif files to corel photopaint X6.
I can only import png files into Corel PP x6.
I think it's a bug from Corel and found no response in their forums .

Is it possible to get the same (or similar) quality as for example this picture from Wikipedia

in preview? Because in preview I can only see black parts clearly and anything other is very noisy at similar zoom as this picture no matter what max iterations I have. When I render the fractal I can see the more similar quality as in image above.
Is it possible to get better preview quality

I am trying to load a .upr I generated in Apophysis 2.09 into Ultrafractal but it generates a bunch of errors and doesn't render correctly.
All the error messages have in common "could not locate parameter xf1_par* in enr-flame-a

If there is a way to capture all the error messages to a file, I will be glad to upload it if that helps.

I have tried loading this same file into versions 2

Hi all.

When writing a coloring algorithm, is there a way to set repeat gradient as unchecked by default? I've tried 'repeatgradient=0' and similar, but no luck yet.....

Greetings. Just an FYI, I've uploaded a new coloring formula to the jam2.ucl public folder. It uses various statistical averages about the orbit points to generate a variety of smooth and TIA-like colorings. The UPR below demonstrates some features: Smooth colorings (layers 1 & 3), TIA-like (layers 2 & 4), using the bailout adjustment parameters (6) to eliminate iteration bands of lay

Does anyone know how to write a formula for this fractal?
I've seen it called a teardrop or mandeldrop fractal, but after much experimentation have been unable to recreate it.

There may already be a formula for this in the database, but I couldn't find one.

This is a formula I found initially through a program for the iPad called Frax...
They use a Line Average coloring algorithm... I googled it and found this.
I have no clue how to program it into UF, so I was hoping to find someone here that did know how...

float xmin = -2.5;
float ymin = -2.0;
float wh = 4;
float stripes = 5.0;
int maxIterations = 1000;
