The Waves transform can be used to generate interesting patterns or textures. The left third of the strip is the image from Group 1 of the upr below; it is the difference of two layers. The middle third is from Group 2, which is the difference of three layers. The right third is the difference of the two Groups. (I made the strip from three separate images using the FastStone Image Viewer.)
Many of you may have noticed that it was impossible to log in to the forum during the past week due to issues at the hosting provider responsible for hosting the Ultra Fractal web site. I'm very pleased to say that this has been resolved and the forum is back up again! My apologies for the outage.
I'm trying to create a Droste effect animation of a single image inspired by M.C. Escher's print gallery version from a Leiden University study. Here is a sketch I made : Thanks to Ultra Fractal and a Droste plugin from Jos Leys, I managed to create the desired effect : As you can see I have a resolution problem on this last sketch due to the very high magnification (about 256 t
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
Hello, Would someone be kind enough to take a look inside the sp3 formula folder. All I'm seeing is a bunch of gobbledygook and the formula I'm looking for is called Cubic Parameterspace 3. I'm trying to upload a parameter set of Ingvar's on DA and it's not working. I have updated all my formulas. Here is what I see inside that folder:
I have been working with a formula for a while, which I have been calling Mandalamandelbrot and Mandaljulia, because it creates nice patters with circular symmetries depending on the location and parameters used. Here are a few examples: https://www.deviantart.com/rychveldir/art/Almond-Ship-931583199 https://www.deviantart.com/rychveldir/art/Mandala-Chain-912805646 https://www
I've tried both with the client on my TR Pro and the server on the 10/20 core i7-6950x and the other way around; regardless of which direction it's going, only one core on the machine set up as the server is used. (tested that just in case it was deciding offload wasn't worthwhile). I checked affinity and it was set to all cores for the server process and the client was set to 20 cores on the
When writing formulas, I frequently make errors that the compiler finds. The compiler then moves the insertion mark to the location of the first error that it finds. The insertion mark is somewhere on the current page, but it's not easy to see.
I'd like an option in Preferences to make the insertion mark more visible. Perhaps larger, or a different shape, or a different color.
The built-in functions include round, floor, ceil, and trunc. Trunc rounds towards zero. For floats, the behavior of trunc is equivalent to the following:
float func trunc(float x)
if x >= 0
There is no equivalent function with < instead of >. In mathematics, I haven't even found a name for this. The best name that I cou
I was hoping that switching the center parameter's keys to smooth interpolation would result in a smooth change of direction in a zoom animation. A gentle, natural-looking curve instead of an abrupt turn-on-a-dime. But the interpolation settings don’t seem to have any effect. It's always the same sharp turn halfway through.
I am rendering some simple fractals, but it seems to take more time than it should. I find that the 4 Efficiency cores are running 100%, while the other 4 Performance cores are all idle. Interestingly, this doesn't happen when I am previewing the fractal. The rendering speed would be greatly increased if this can be fixed. By the way, I am using a MacBook Air with an M1 chip.
I was just playing with a fractal and noticed that there should be a very nice way of coloring my fractal if I juuuuust got the gradient offset and color density right. But I need to adjust them one by one, going back and forth. I think for these two it would make sense to have a 2D explorer - like we do for complex variables - where we can adjust color density on the x-axis and gradi
This month I've been using Ultra Fractal to make illustrations based on drawing prompts generated by an AI. Kind of a frivolous exercise, but it has definitely sharpened up my techniques for using coloring formulas.
You can read about the prompts here: https://www.aiweirdness.com/botober-2022-draw-human-draw/ and see the pictures I've made here: https://mrvelocipede.tumblr.com/tagged/botob
I see the only version of Ultra Fractal available for macOS is still an Intel build. Are there plans to do a build for the new Apple M1 processors? I imagine it would be a lot faster for those devices.
These, often called Strange Attractors, are iterative systems that don’t seem to go anywhere, but do (approximately) repeat. Unlike most of the formulas in UltraFractal (UF), the iterations don’t diverge to infinity or converge to a point.
A simple example is the Clifford Attractor, named after Clifford Pickover, as in Layer #1 of the upr file at th
After reading Crystal Wizard's post of February 4 (https://www.ultrafractal.com/forum/index.php?u=/topic/832/dr-pickover-s-suggestion), I got inspired, or perhaps carried away.
In the Tutorials and Tips section of the forum, I have put a tutorial on my new Chaotic Attractors coloring formula and a upr with 15 sample layers. As a teaser, renderings of two of the layers are below.
HEIFs are about 1/3rd the file size of PNGs, which are the smallest lossless files Ultra Fractal can write.
I’m converting the PNGs to HEIFs with another app but it doesn’t batch-process very well. It’d be sweet to have lossless HEIF right from UF. Even better if the files are saved with the .heif extension not .heic because Final Cut Pro and other apps don’t recogni
