So I've been trying to find different ways to get rid of this stutter that occurs at the start and end of my looping gradients.
The slower the animation, the more obvious it is but it's still there even when it's just 6 seconds on loop.
Example posted to YouTube
It occurred on my ancient PC and it still happens on my newer one which makes me think it's a software issue. Does anyone h
I hope the title suggest it all. Could some please explain the main differences?

I found an interesting and visually pleasing phenomenon called Domain Coloring. Based on mathematical formulas, I don't know how closely it relates to fractals. I'm a big fan of rainbow coloring and when I stumbled upon these images I was mesmerized. Is there any way to make something like this in UF?
Here's a link: https://www.dynamicmath.xyz/domain-coloring/dcgallery.html
The help file clearly states that, for complex z = (x,y),
|z| = sqr(x) + sqr(y).
It does not say that, for float x, |x| = sqr(x), but it should.
I recently discovered that the first public release (Ultra Fractal 2) was February 8, 1999. That was 25 years ago this year, and at the time we didn't know it and didn't celebrate the anniversary.
I don't know about version 3, but version 4 was released in 2006, version 5 in 2008, and version 6 in 2017.
I first bought Ultra Fractal 4 in September 2006. How about you?

Hi, after using only notebooks for over a decade, I am thinking about getting a (Windows) desktop PC. Not being much of a gamer, my primary concern with performance is deep-zooming the Mandelbrot set in UF. Does anybody have a suggestion for this, or even a benchmark computed on their machine?
I've read Frederik suggesting an i7. Is UF specifically tailored to Intel? I never read anything abo
I loaded a saved upr after changing a formula. I got the unhelpful message
Could not locate parameter 'which' in 'GenericGradientColoring' in 'Documents\Ultra Fractal 6\Formulas\Standard.ucl'
The missing parameter actually was in 'Shape Distance' in jlb.ulb. The chain is
Standard.ucl has GenericGradientColoring
jlb.ulb has Color by Distance, a sub-class of GenericGradientColoring
When I made a new class with a first line like this:
class NewTransform(UserTransform)(
instead of the correct
class NewTransform(common.ulb:UserTransform)(
the UF compiler made no complaint. NewTransform just didn't show up on my list of available UserTransform plug-ins.
(I don't see how the compiler would even know to look at this class to check for errors.)
I wrote a class that's a subclass of common.ulbivergentFormula. ←wth why a smiley?
The formula is purpose-built for a coloring algorithm where it is used hardcodedly (not as a class param), and I need to set the @p_bailout parameter to what the coloring needs (also hardcoded). Is there a way to do that, without writing my own m_bailout 'replacement' member in the class and overriding IsB
I am testing UF6 right now, and try to make the first formulas. For this i try to translate the trigonometric functions from here ... to UF.

(UF should have a complete 24 set of all trigonometric functions, for float and complex.)
Now i stack, because i not get it done to return a complex value.
Can somebody tell me how to return a complex

Im having odd, random crashes on my new macbook pro. awesome...
Considering the small, text based size/structure of .ufr's..
I assume an auto backup file thats generated in text and updated overtime i make a change would be easy to implement.
if uf wants to crash, fine. simply access the backup text file with every state of the ufr's history.

When all pixels are Inside, the Statistics panel shows Min. iterations 0 and Max. iterations 0, and nothing on the Iterations graph. Shouldn't both of those values be #maxiter, not 0, and the graph be a vertical line?
Since I've been out of the loop for so long, I have no idea even how old Uf6 is. It seems like this forum is seldomly visited by people, the mailing list seems to be long dead, the showcase only contains ancient stuff, the pdf manual is incomplete, the online manual contains dead links, and to top it off, the subdomain for the public formula library seems to be dead in the water. Is there any hop
There are some things in the formula editor which would come in handy that I would like to see.
For loops.
From the C++ documentation ( https://cplusplus.com/doc/tutorial/control/ ) :
The for loop is designed to iterate a number of times. Its syntax is:
for (initialization; condition; increase) statement;
Like the while-loop, this loop repeats statement while condition is true.

Have not used the application for some time UF6 Cannot open any formulas with error code as above and message "Cloud file provider is not working"
I recently picked UF.5 up again to do some math experiments. I wrote a coloring algorithm, but calculations became very slow at a zoom depth of 1e24. I read UF.6 was a lot faster and maybe perturbation could also help (as I'm using Mandelbrot).
Opening the fractal in UF.6, the coloring algorithm doesn't seem to work anymore. I tried loading a non-perturbation version of Mandel, but it still d
I am struggling to implement automatic differentiation in a plug-in library... can anybody help? No one has ever tried to add it at all, and it is a pain to find the derivative or the integral by hand.

Where can I find examples of animated fractals with more than a million iterations in color and possibly accompanied by music
Hi, this is my first topic here and I want to know how do I make matrices in Ultra Fractal.
Thanks!
Anybody know how to do this?
Some formula writing would be easier if the Formula class in common.ulb had in its protected area
complex m_c
and functions like
func SetC(complex c)
m_c = c
endfunc
complex func GetC( )
return m_c
endfunc
Including these changes would not break any current fractals and would allow simpler switching from Mandelbrot-type to Julia-type.
Has anyone else experienced a massive slowdown running windows 11 compared to windows 10? I ran the exact same Ultra fractal file on my 2 computers, and the windows 11 computer is about 2.5x slower. With the faster RAM, SSD and CPU, I was expecting about a 2x increase on performance in the newer computer. Both computers are running the same version of Ultra fractal.

Dear fractal lovers,
I would like to inform you that I am putting an end to the collection of UF fractals from the Ultra Fractal forum on the web via https://www.ultrafractal.com/forum/.
The numbers of fractals that still appear on this forum are sufficiently small to be kept by everyone.
Of course, the monthly collections remain on the web and can still be consulted and downloaded t

Hello,
I am writing a coloring algo at the moment and I tried using min(val1, val2) where val1 and val2 are two floating point values, and the function does not exist (error: invalid function). So I went looking for an equivalent function and I cannot find one. Does UF not have such a fucntion? It seems like such a basic thing. Am I just overlooking something?

Hello,
I have a bunch of gnarl formulas, and I generally color only the inside. Is there a way to set a default inside coloring algo such that the previews show anything interesting at all?
Thx in advance,

The rotation parameter is write protected.
Somebody know a elegant way to do rotation in the formula?
Usable in deep zoom.

I have created my own formulas and have even created an entire script for Ultrafractal with interchangeable parameters. I was wondering, Has anyone tried using the formulas created in Ultrafractal and tried to create a 3d fractal creation in Mandlebulb?
I am trying to figure out how I could do that and am for some reason having a mental block or is it just not possible?

Hello all! I'm new to this, getting deeper into UF and enjoying it immensely!
I've been scouring around trying to find a particular orbit trap, wondering if anyone here recognizes it. Looks a bit to me like foam bubbles...
Any help or direction would be appreciated!

Somebody know converters to UF, for example from ChaosPro?
