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!

Hi All,

The was only one fractal on the last day of the month.

You can find this one and the older collections at the cloud of Microsoft:

Any idea what's causing the black to appear over the fractal image? I suppose one of the variables is out of range but I happen to like the design I'm seeing on screen and don't wish to vary it too much. Thanks!

The Absolute Julia transformation is made by taking a fractal and mapping each coordinate to its square root.

I usually render to disk with a resolution far higher than that of the fractal window. Sometimes, this means that perturbation mode would probably be used for the rendering, but I have no way of setting the precision level because it's only shown when that mode is also used for the fractal window.

Hence, I'd either suggest such an option in the rendering dialog, or to make the perturbation pr

I have a formula and want to add a new parameter to it without breaking past fractals. The formula has a version number in it, such as this declaration in the default section:

int param v_SFormula
caption = "Version (SFormula)"
default = 100
visible = @v_SFormula < 100
endparam
If the new version of the formula has "default = 101", how do I put in the ne

I'd like to try doing a zoom into the Mandelbrot set for a talk that I'm doing in January. I know to use exponential on the magnification. Is there a rule of thumb for the spacing of key frames? Any helpful tips?

I was able to make input fields based on numerical values and Pull downs with Text Choices that equal values. I have a two questions.

I know ultrafractal is specialized programming language so I know it has limitations and I would like to find out if this is even doable...

If I want an input value to be text... would I be able to program it where that text gets printed on the Fractal

Hi, has anyone found a way to hook a MIDI controller into Ultra Fractal?

I'd love to set the values of some of the function parameters to knobs, maybe have the timeline on a slider.

Any ideas or experiences would be appreciated!

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 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've tried to reproduce the image posted here but failed, even at the "Precise" setting for Perturbation: essentially, the whole center is 'missing'. While such problems can always occur, I thought I'd report this in case you want to make the algorithm a bit more robust.

I do it by luck with a switch on Julia classic with image plug-in.

Hello,

I recently updated my CPU and got a Ryzen 9 3900X with 12 cores and 24 threads and that caused me to find what I think is a bug. To be clear, the program works fine, the image is rendered, so it's more of a nuisance than a real problem.

What happens, is that for images wider than 1931 pixels, certain thread counts will cause 50% of the image centered horizontally to be renderd firs

Does anyone know how to write a formula for this fractal?
I've seen it called a teardrop or mandeldrop fractal, but after much experimentation have been unable to recreate it.

There may already be a formula for this in the database, but I couldn't find one.

Switching the order of the two formulas, changing the parameters a bit, and switching to Mandelbrot mode, gives a fractal with some convergent and some divergent areas.

The second type of plug-in is “Combo.” It allows combinations such as (f1+f2)/f3 or f1(f2)). The latter means evaluate f2 to get a new value, then use that value as input to f1. The following example starts with Perlin 3D noise, followed by repeats of a Combo of Mandelbrot, Mandelbar, and Function.
