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

I download the evaluation of v.5 and had been playing around with it for the past week or so. I really like this product, I'm very experienced in Photoshop and other such programs for my photo work, but this product is a very enjoyable challenge. And some of the artists work I've seen doing this is just insane. One of the reasons that convinced me to buy it was the community respo

I was searching for this answer, but couldn't find a definite. Is it possible to import into a layer, another file format, like a PNG or TIFF. I can accomplish the same thing the other way by importing the Fractal export in readable format into PS and layer it there, but was just wondering if possible during the construction of the Fractal itself.

Also, I'd like to know the size limit I can

Complete newly to UF. I'm going through the tutorials and I've run into a problem with pasting data from the tutorial into the program.

The instructions say to copy this text, then paste it into the gradient editor.

Hello! I don't know much about this program, and I'm really bad at math so I don't know what I'm doing here. But I have a sequence of numbers that I would like to somehow punch into the software and see what it looks like.

How would I do this?

I understand I have to make complex numbers, but I dont know anything about writing equations so I was wondering if someone could help me with that

QuadMirror, in jlb.ulb, takes a block of your fractal and mirrors it multiply in all four directions. You specify nx and ny, the number of repeats horizontally and vertically. There are two ways to specify the block to repeat.

(1) Visualize your fractal divided into nx by ny blocks. Specify any point in one of them. This block will be unchanged, and the others will be mirrored around them. Th

I am absolutely brand new with this software and am finding the tutorials frustrating in that the images do not seem to coordinate with the views I see in the toolbox section at the right of the screen. The tutorial images seem to be outdated and therefore I can't learn the objective at hand.

I'd like to start with simply modifying a formula. Any help is much appreciated.

I was a user of coreldraw (with photopaint) X4 and moved to corel X6.
I could import very correctly tif from ultrafractal to corelphotopaint x4.
Now, it is impossible for me to import UF tif files to corel photopaint X6.
I can only import png files into Corel PP x6.
I think it's a bug from Corel and found no response in their forums .
I tried exporting with the various options in U

Plug-in Tutorial: Image Traps Part III

This is the last part to the tutorial. All of the example uprs use plug-ins for the Colors slot. Two of them are slow in rendering as they use an emboss convolution filter (3 min 31 sec for EtchedMetal and 16 min 22 sec for EmbossedGnarly on my computer - Intel quadcore 3240 3.4 GHz). Be sure you have Ultrafractal set so that the minimum number of threa

In writing this tutorial some bugs were found in some of the plug-ins. Please download a new copy of reb.ulb before continuing.

Continuing with a survey of the main plug-in slots the next section is Images and Coloring. The primary slot is Colors with a default plug-in of No Color. The base class is ColorTrap, which is in common.ulb. The following plug-ins will plug into the Colors slot, but

This formula is derived from the Ducks formula in sam.ufm with multiple modifications. Bailout is determined by the number of iterations rather than a convergence or divergence criteria, so an iterations parameter which is independent of the value on the Maximum Iterations value on the Formula Tab has been included. The value for 'Iterations for Bailout' must always be less than the Maximum Itera

'Widgeon', a variant of 'Ducky Plus'.

'Widgeon' is based on the same principle as 'Ducky Plus': change of the kind of operation during the iteration process. In 'Ducky Plus' there are 3 steps, each with a number of iterations, here in 'Widgeon', the second step consists of only one iteration.
So for each treated pixel the iteration series starts with a certain formula, determined by the pa

This is a 3D raytracing formula with 60 3D plug-in formulas available. Two coloring formulas are available: 3D Fractal Coloring Gradient Progressive and 3D Fractal Coloring Direct Progressive.

Parameters and Options:
The main raytracer has a number of options and parameters. The main algorithm is based upon an article by Hart, Sandin and Kauffman for estimating the distance from a point to

For the Embossed Traps tutorial open Object Formula Switch Lite and load the the Switch Trap Embossed plug-in. In the Trap Parameters section note the Fractal formula plug-in, which is actually a specially designed Trap Shape that only works with Switch Trap Embossed. There are 104 to choose from. The default is Rose Range Lite and is closely modelled after a formula of Kerry Mitchell's. The Tra

For the Slope Lighting tutorial open Object Formula Switch Lite and load the the Slope Switch plug-in. Virtually any Switch formula can be used to apply the slope plug-in, but for this tutorial we will stay with Mandelbrot Julia Switch. The slope formula requires a specific coloring formula, called Lighting. There are several of them available in the Ultrafractal database. We will use Lighting wi
