I've added a revised version of QuadMirror to jlb.ulb. QuadMirror2 is a transform that takes a rectangular block from a fractal layer and tiles the fractal evenly with the block, mirroring it both horizontally and vertically.

The user specifies the number of blocks in each direction, the center of the original block, and where the original block goes (unmirrored). Because of the mirroring, t

I am currently on working on creating some fractals and animating them.

I had a question... I tried doing a fractal animation and it takes about 3-4 days to render and then at the end the log says "Error Saving image (error)

Is there another log where I can figure out what the exact error was?

According to the log it took close to 60 hours to finish so I do not want to go through it

Does Ultra Fractal offer any of the lambda fractal planes, as described in this link? I am aware of the inverse fractal mapping but was wondering if any of these others are possible as well?

I stumbled upon an amazing combination of variables: the standard Pixel formula with Gradient for family Outside coloring (sam.ucl) and the Inverse fractal plane mapping. How does such a transformation take place from a bunch of squares formed by the gradient to a beautiful rounded geometric pattern? I am baffled and pleasantly surprised!

bonjour, je voudrai savoir s'il serait possible de m'aider car j'ai voulu ré-ouvrir des projets et lors du démarrage du logiciel j'ai un message qui me dit qu'il manque une formule (JLB QUAD MIROR - jlb -ulb). j'ai essayer de mettre un jour ma liste de formule public et rien nouveau. le problème recommence ... j'a l'impression que c'est après avoir effectué des

Hi, after using only notebooks for over a decade, I am thinking about getting a (Windows) desktop PC. Not being much of a gamer, my primary concern with performance is deep-zooming the Mandelbrot set in UF. Does anybody have a suggestion for this, or even a benchmark computed on their machine?

I've read Frederik suggesting an i7. Is UF specifically tailored to Intel? I never read anything abo

Has anyone tried importing UPR commands from Apophysis into Ultra Fractal? I just get dozens of error messages (see screen shot). There will be something rendered in the fractal window, but it doesn't look much like the original in Apophysis. I've updated the UPR database, but it doesn't help. I've tried exporting from both Apophysis 7X and Apophysis 2.09, with the same result.

I'm running b

I have a photograph that I would like to use in UF if I can change it. It has many areas that are various brightnesses of a fairly neutral gray. Is it possible to make a mask just of these gray areas?

I'm New to this forum and I wan't to thanks all the parameter's sharer. I'm actually from France and devellop all my work with fractal's, in plastic and numeric art.

Do you know how can upgrade the size of iteration (aka Trap Threshold) with the Direct plug-in > Orbit Trap > Image

Hello all,

I'm finally checking out UF6, and the deep zoom is amazingly fast! I've run into a question, though. In a lot of my older fractals, I used Lyapunov coloring layers in deep(ish) zooms. When I load some of those old parameters into UF6, it looks like Lyapunov stops working at the deeper levels of magnification. I used to fix that by manually adjusting the Additional Precision. Can an

Trying to print out one of the fractals I created. What is the recommendation for printing.

I would like to print something like a 30x20 in size.

Can anyone give me some tips on what export settings and to what type of file would work best?

Thanks in advance!

Is there a practical maximum zoom magnification for the Mandelbrot formula with perturbation? UF is not optimized for deep zooms, but I'm curious.

Who's gone deep? The one I'm looking at now is E120 so far, using about 150,000 iterations, and all seems well.

(This question arose because of the video of a zoom to E2011, made using Kalles Fraktaler,
