Hello!
I'm currently rendering a fractal that told me it would take 8 hours initially, quickly rose to 9 hours, then 10 hours. Now it has been running for almost 3 hours and it still predicts between 9 and 10 hours.
Here's my guess of what is happening: The fractal is basically a spiral with the highest iteration counts toward the center of the image, so I would expect the rendering to sl

Hi All,
This month only one but a very beautiful "16 in one" fractal in the collection.

Hello,
I recently ran into the problem of wanting to use the switch to Julia mode on a pretty multi-layer fractal. It would be great to have a way of using all layers for the new Julia fractal, rather than just the active layer. I get that it's possible to do them one by one and copy-paste them into the same window, it just seems a lot more tedious that it has to be.
Best regards,
Phi

Hi, I've been playing around with the image Trap coloring as mentioned in the manual, but got curious, is there something similar that can take a movie file instead of a still image? Or can it be coded? Thanks!
(Literary readers: yes, this is a reference to the Wallace Stevens poem, “Thirteen Ways of Looking at a Blackbird.”)
This image has 16 fractals arranged in a 4 by 4 array. All 16 have the same gradient and the same Formula tab (Julia from Standard.ufm). All of the Outside tabs use Plug-in Coloring (Gradient) from Standard.ucl, and the Distance Coloring plug-in from jlb.ulb. The di

Now that Windows 11 has started rolling out to end users I would be interested to know if Ultra Fractal has been tested on this platform.
I'm assuming UF will probably run ok on Win11?
Thanks.
Greetings Folks,
This is my first post here and I would like to express my appreciation for this wonderful software. Frederik Slijkerman is clearly a world-class programmer and an all-around awesome guy and I value what he has created.
I've been fascinated with fractals since I discovered them in 1991 and wanted to incorporate some fractal zoom sequences into an animation that's synchroni

Here's a fractal using some of my recent formula classes. The iteration formula class is Threelevel, and the coloring is DistanceColoring. ThreeLevel is inspired by several formulas with Barnsley in the name, where one formula is used if some function of z is above a critical value, and another if below.
Feel free to tweak.

Hello,
I'm not sure what this isn't a thing, when using the explorer I can press escape to exit, but when I'm in eyedropper mode, this doesn't work. It should be straightforward to add this and would make it a lot more convenient.

I have updated my Distance Coloring plug-in (in jlb.ulb) in several ways.
New distance plug-ins:
Gaussian Integer, similar to the coloring in Standard.ucl. This often gives interesting results when used only on early iterations.
Triangle, like Circles or Square, color according to whether z is inside or outside.
Modified plugin:
Exponential Smoothing, with addition
(I may have asked for this before.)
When debugging a formula, I don't need 15 decimal digits of precision in a printed line to see what's happening. A setting like
$decimals 4
would be nice to have. Not necessary, but nice.

I have uploaded new Distance Coloring plug-in files to jlb.ulb. These are similar in concept to Orbit Traps: for each iteration, as the z associated with a pixel moves in the complex plane, information can be accumulated about distances. Afterwards this information is used to calculate an index into the gradient for coloring. See a sample image and a upr in the following post.

I've created serveral animations where I create with outputing slides to png's.
Though I noticed sometimes if I make a zoom animation too fast... the slides look blurry. Are there any tips anyone can give as what is a good "time frame" so the zoom is not too fast ratio to time so it wont look blurry?
I hope that makes sense.
I can upload a few frames if it helps.
Thanks in adva

This coloring UCL file is supposed to detect period of an orbit, and assign color index accordingly. Testing on plain mandelbrot set gives a noisy result (can't attach image here I guess, any color map, linear 0.1; values are in 0-20 range). I can see nothing wrong with the code and I have turned of guessing, normal periodicity checking, messed with tolerance, max iters, even tried extra decimals

Hello,
over the last years I have spent quite a bit of time thinking about how to render my fractals in the best possible way. I'm quite sensitive to image quality, at least I think so, since I'm often the only one to complain about it in the first place.
Just recently I found a great way for getting phenomenal results that doesn't include any costly software, it uses the completely free

Hi!
I’m new to this list but about 20 years ago I was a member of the UF Mailing List for a while together with my former wife Sharron. We had a fractal website called “Fracternity”, and maybe here’s the one or other fractal veteran remembering us vaguely. I have stopped making fractals for a long time, but now my interest is back, and in order to render one of my old

Hello,
this one might be a low priority one, but it's something I noticed and thought I should let you know. From what I can tell, UF uses image pixel column count to separate the image into pieces that are being worked on by each thread. This works fine in almost all cases, but I encountered something interesting. If only a small area is left for calculation, and it is comparatively narrow,

I don't have any commercial software to combine the tiles output into a single image. And wouldn't know where to begin in any case.
Is there a tutorial or easy-to-use free or low-cost solution to do this?
Thank You
This is an example of what has happened to me any number of times while developing plug-in formulas.
