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

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

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.

Note: because these downloads are new, Windows 10 might flag them a

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

I’ve uploaded a new version of jlb.ucl with three new coloring formulas.

Decomposition2 is a generalization of Decomposition in dmj.ucl, by Damien Jones. It colors by the angles of #z, or of one of various functions of #z, at each iteration.

Statistics2 is a generalization of Statistics in lkm.ucl, by Kerry Mitchell. It colors by various statistics of #z, or of one of various funct

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.

I have been working for some time on ways to generate new fractal shapes, and also to be able to switch easily from Mandelbrot type (M-type) to Julia type (J-type). Here is what I’ve come up with.
UltraFractal formulas usually depend on two complex values, z and c. Usually z starts with the pixel value and changes throughout the iterations. Usually c does not change with the iterations; for

I have a square fractal, say 600x600 in the UF6 window. If I change it to 900x600 in the Image tab, the apparent magnification changes. I want to make it wider without changing the center or the apparent magnification. Is there a formula for changing Magnification in the Location tab that will do this?

It turns out that some combinations of formulas don't render properly unless Periodicity Checking is Off.

Example 2 also uses Power as the Initial Formula, but Two Formulas as the Main Formula. Formula #1 is a J-type Lambda, and Formula #2 is an M-type Lambda. Bailout is Divergence. Different bailout types give different results.
