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.
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 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. Load the upr in
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?
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
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
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.
I'm happy to announce the release of Ultra Fractal 6.04. This free update for existing version 6 users fixes several issues on Windows and Mac, especially when running on macOS 11 (Big Sur). You can download it here: https://www.ultrafractal.com/download/
Just let me know if you experience any problems with the update.
Note: because these downloads are new, Windows 10 might flag them a
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
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 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,
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.
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.
