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,
Phillip

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

Hello, i'm a uf6 apprentice and I have a question.

I'm testing and studying Kerry Michell tutorials
As you can see, my image is not as perfect as the image obtained http://www.kerrymitchellart.com/tutorials/basket/basket.html

I have made a copy and pasted of the upr of kerry and I have rendered, then I have compared both images and mine imge has defects. because?

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,

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.

last week i got an error when I tried to start UF version 5. I had been planning to upgrade to version 6, and I thought this might solve the problem, but it persisted following the new installation.

Liesbeth posed basically the same question in January.

Hello,

I'm on a roll, so here's a 3rd post. I have intermittently run into an error message when using the explorer to vary color density. This happens when something else (preview or job) is also rendering at the same time. As I move the mouse back and forth over the explorer window, errors occasionally pop up, usually complaining that something is not a floating point value:

In the Formula window, bool params have their caption to the right of their check box. If the check box were to the left of the window, there would be room for a longer caption to be visible.

A very minor request for the next minor release.

Thanks to Frederik for this terrific program.

I tried changing fonts in the formula editor from the default Consolas to something else, like Times New Roman or another serif font. These other fonts are not mono-space, but they display as if they were mono-space, fixed-width and ugly, so not really usable. Of the Windows fonts, only the true mono-space fonts—Consolas, Courier New, and Lucida Sans Typewriter—are useful.
