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

(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

Hi All,

This month no new fractal parameter files in the collection.

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.

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 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

Hello,

I upgraded to UF 6.04 today and every time I open the explorer window for any parameter I get a huge CPU spike. This happens even if my mouse is nowhere near the window and nothing else is rendering. This takes several seconds and despite having a 12C/24T CPU it drains my computer of resources to an extent that even the playback of windowed Youtube Videos starts to stutter.

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,

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,
