Hi All,
This month no new fractal parameter files in the collection.

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.

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.
best regards,

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.

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

Just let me know if you experience any problems with the update.

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.
I changed a couple of parameter names in a plug-in. When loading an old upr, I got this message:
The mistake is actually in a plug-in of a plug-in of a plug-in, but the error message refers only to the top-level formula, which is not in error. The missing parameters are not in the top-

This fractal has "dirt" on it (speckles). If you zoom in on the mandelbar the noise pattern changes so it's not correct. I tried everything with bailout and even added precision but the problem remains. Actually with added precision the picture completely disappears.
I guess I can't attach here, so I'll give upr and Bugs.ufm below,

Is there a way to set formula parameters programmatically, be displayed in the GUI and allow further manual tweaks?
Eg I have a formula parameter set q1,.., q8 which I give random values programmatically but then want to tweak manually.
I’ve uploaded a new version of jlb.ulb with a new fractal plug-in formula, ThreeLevel. It’s a Barnsley-type formulas; these formulas define a critical value, and at each iteration some combination of z and c is compared to the critical value. If the combination is above the critical value, one formula is used; if below, another formula is used.
ThreeLevel uses two critical values
I have some of the help files that are referenced in online formulas, including ones from lkm, mt, reb, and sam, but I don't have any of the dmj-pub help files. Are all of the help files still available somewhere?
They don't seem to download when I update the formula database.
