I tried changing fonts in the formula editor from the default Consolas to something else, like Times New Roman or another serif font. These other fonts are not mono-space, but they display as if they were mono-space, fixed-width and ugly, so not really usable. Of the Windows fonts, only the true mono-space fonts—Consolas, Courier New, and Lucida Sans Typewriter—are useful.

Hi all,

No new fractals this month.

You can find the whole 2020 collection and the older collections at the cloud of Microsoft:

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

In the Range field of the Exploring tab, I can't enter a number like 1e-7 or 1e5. However, if I enter .00001, UF changes this to 1e-5 and I can edit the number.

Also in the Range field, I can't enter a number like 1.5, as the decimal point is immediately deleted. However, I can enter .5, which UF changes to 0.5, and I can then change the 0 to 1.

This behavior seems limited to the Range fi

I'm debugging a new formula. All the printing so far is in the constructor. I get many more lines of printing than I expected, some of the same things over and over.

I thought that the constructor was only invoked once.

When is it really invoked? How can I avoid the excess printing?

I have been working for some time on ways to generate new fractal shapes, and also to be able to switch easily from Mandelbrot type (M-type) to Julia type (J-type). Here is what I’ve come up with.
UltraFractal formulas usually depend on two complex values, z and c. Usually z starts with the pixel value and changes throughout the iterations. Usually c does not change with the iterations; for

I have a square fractal, say 600x600 in the UF6 window. If I change it to 900x600 in the Image tab, the apparent magnification changes. I want to make it wider without changing the center or the apparent magnification. Is there a formula for changing Magnification in the Location tab that will do this?

Hello,

I'm pretty sure this isn't intentional. The anti-aliasing in the working window has become noticeably worse in the latest version, to the point that I had to double check whether it was active at all. Here's an example comparison:
It's even more obvious with the default image, but i haven't saved a copy of that from the older version.

Best regards,

Hello,

I was about to explore the Mandelbrot set when I ran into a glitch while rendering. It looks exactly like the kind of artifact I get when periodicity checking fails. I can usually just turn it of, but this was using perturbation (precise).

Here's an image:


The problem occurs only in one of the two layers (the one that uses Triangle Inequality Average)

Hello,

I recently worked on a few relatively slow rendering fractals and I frequently run into previews that take serveral minutes to render. However, I can already see what I want and I would like to use the explorer to change parameters. I know I can turn off AA and/or change the size of the image too.

It would be awesome if we had a button to pause the automatic rendering of the previe

Hello,

I'm on a roll, so here's a 3rd post. I have intermittently run into an error message when using the explorer to vary color density. This happens when something else (preview or job) is also rendering at the same time. As I move the mouse back and forth over the explorer window, errors occasionally pop up, usually complaining that something is not a floating point value:

Example 2 also uses Power as the Initial Formula, but Two Formulas as the Main Formula. Formula #1 is a J-type Lambda, and Formula #2 is an M-type Lambda. Bailout is Divergence. Different bailout types give different results.

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.

Hello!

I have been lurking here for quite a while, with only the occasional post, but over the years I have spent lots of hours in UF, and I enjoy it a lot. What got me into UF originally, was the fact that I can write my own formulas, which I have repeatedly done.

Just last week I tried a way of combining the Mandelbrot Set (nice shapes, but nothing new at this point) and the Burning Shi
