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.
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
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.
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'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:
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.
I'm pretty sure this isn't intentional. The anti-aliasing in the working window has become noticeably worse in the latest version, to the point that I had to double check whether it was active at all. Here's an example comparison: It's even more obvious with the default image, but i haven't saved a copy of that from the older version.
I was about to explore the Mandelbrot set when I ran into a glitch while rendering. It looks exactly like the kind of artifact I get when periodicity checking fails. I can usually just turn it of, but this was using perturbation (precise).
Here's an image:
The problem occurs only in one of the two layers (the one that uses Triangle Inequality Average)
I recently worked on a few relatively slow rendering fractals and I frequently run into previews that take serveral minutes to render. However, I can already see what I want and I would like to use the explorer to change parameters. I know I can turn off AA and/or change the size of the image too.
It would be awesome if we had a button to pause the automatic rendering of the previe
My default upr uses SwitchComboFormula in jlb.ufm plus JLB_SwitchFormula, JLB_SwitchCombo, and JLB_MandelbrotSFormula in jlb.ulb. I had a typo in the Mandelbrot, default = 1" in a parameter block. When starting up UF, I got a large number of confusing and not helpful error messages, as in the screen shot below.
When the (blank) fractal loaded, I clicked on the top line, SwitchCombo
