Now two examples with just two layers, a top layer for the lines and a bottom layer to color the cells. Here’s one with 200 rectangles. Because cells are colored with index equal to n/Nmax, shuffling the colors often gives a more pleasing result.

Years ago, rkb.ulb included code that allowed the making of Mondrian-type images, but it is no longer in that file. I thought about this for a long time and decided to develop such code, though mine is totally different. (The rkb code used Trap Shape, and mine is entirely in the outside coloring.) Here’s an example of the result. Not as good as Mondrian’s, but reminiscent. And not at

I've been a longtime user of Photoshop and other graphics applications, but not spent much time creating fractals. I've looked at hundreds of fractals and there is one style in particular I really like and would be happy to create in a variety of ways. I think it's referred to as chaotic bundle or chaotic thread, but I may be mistaken regarding this. What I need help with is the steps in UF to cr

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.

The available formulas, all in jlb.ulb, are listed below. All of them have parameters that can be changed and hints that describe the options.

Do nothing (a placeholder to be used if no formula is desired)

Divergent formulas (usually)
Mandelbrot
Mandelbar
Function
Power
Polynomial
Gnarl
Gnarly
Perlin 3D Noise
Convergent formulas

I have just uploaded Simple Switch Formula to jlb.ufm. By default it calls my SwitchCombo plugin in the new library, jlb.ulb. This allows generating new combinations of formulas; all of them allow switching from Mandelbrot-type mode to Julia-type mode or vice versa with the F7 key or pressing the Switch Mode icon on the toobar. Both divergent and convergent formulas, or some of each, can be used.

Hi!

More about plugins …

I’ve been doing some readings about plugins and this is my interpretation of what I’ve read.

In the computer world, a plugin is a program that adds functionality to a larger program. In the context of UF, plugins add functionality to UF but are customized for particular formulas, algorithms, or transformations.

Thus, it follows that one

Hi!

To create a fractal image one could understand the relevant math (i.e., Fractal Geometry) and the functionality of the software that generates the image. The relevant math is beyond the grasp of most artists and the functionality of complex software such as Ultra Fractal is, at least initially, also beyond the grasp of most artists.

As an alternative, one could ignore the math and id

Hi!

I understand, maybe incorrectly, that a fractal image is (1) a set of numbers, generated by a formula, and displayed as POINTS, and (2) rules for coloring the POINTS.

In UF, is there a way for replacing the POINTS with SHAPES (e.g., a triangle)?

If so, how do I do it?

Thank you!

Hi!

I want to create a JPG file for printing on canvas. The canvas size is 16 inches (W) by 12 inches (H). At 600 PPI, the JPG file is 9.600 pixels (W) by 7.200 pixels (H).

To begin a fractal, what parameters should I use in the “Fractal Properties: Image”?

Or, does it matter? If UF files are scalable like SVG files, then only the width/height proportions matter.

Hi!

I am a newbie using Ultra Fractal 6.02 Extended Edition running under Windows 7 Pro, 64-bit, Service Pack 1.

Out of curiosity, how often do you use the Switch Mode?

I can see myself using the Select Mode often; not so the Switch Mode.

Thank you!

Hi!

I am a newbie using Ultra Fractal 6.01 Extended Edition running under Windows 7 Pro, 64-bit, Service Pack 1.

To learn Ultra Fractal, I am following the Tutorials. When applying color (Layer Properties > Outside > Browse), whatever I select will change the color parameters but not the pattern. Am I right?

Thank you!

Here are some belated examples and a few tips...

The first example is a good starting point for exploration. Note that the Drawing Method on the Formula tab is set to One-pass Linear and that Repeat Gradient on the Outside tab is un-checked. The gradient is greyscale. You can try other types of gradients but the results will vary.

Find it in mt5.ucl.

This coloring algorithm is based on Chapter 14 of Clifford Pickover's book Computers, Chaos, Pattern and Beauty, where here introduced "Popcorn" and a number related gnarly equations. The rendering method used in the book, and here, is similar to that used by Flame Fractals. This doesn't suit Ultra Fractal's native method of calculating fractals, so the whole process has

Hello. I have Ultra Fractal 6. The program has given me so much joy. I did short films in HD size and I did render to avi. Recently, I wanted to make a movie in size 4k. And problems began. The file renders to the end, but only 4 GB (approximately 160 frames) is saved. And he does not start from the beginning, but somewhere from the inside. Is it impossible to make a 4k movie with this program, d

Ok is there something I'm missing? Is there an easy way to set keyframes for color cycling that will keep looping forever. Currently, it seems like i have to set a key frame for rotation at 200, then keyframe it to -199, but then how do I make it just keep looping from there without having to reset with another keyframe back to 200?

Basically I miss just being able to say, rotate at this spee
