2022 May Challenge: Chebyshev and Voroni2022 MAY CHALLENGE: Chebyshev and VoroniFractals have become part of the culture of mankind, especially after the recent discovery that cancer cells grow in a fractal, rather than in an arithmetical manner. Most people hope that the various national and tribal cultures will become more revered and more widely shared, rather than cancelled by genocide, war, or global catastrophe. With these considerations, we will focus this month upon two mathematicians whose work has contributed to fractal concepts, the “Father of Russian Mathematics” Pafnuty Lvovich Chebyshev and the Ukrainian mathematical and tessellation theorist Georgy Voronoy.In my stash is a parameter for 14 Voroni textures, all of which were made from OM.ufm Chernyshev. It is located here: https://sta.sh/01hfihgfps9y Please note that I STARTED with OM.ufm (not OM2.ufm) Chebyshev formulas and added the SAM “Voroni” transformation.You might say, “UFR has already done a texture challenge with SAM.uxf “Voroni.” That’s true. However, Georgy Voronoy is the only Ukrainian mathematician of whom I know to figure in a Public Formula. Thus, I have created a texture set that I hope will have some extra Voroni texture ideas. Three of the fourteen have a .ucl with direct coloring. Three others have the MT.uxf “Sierpinski Glass” as well as the SAM.uxf “Voroni”.

It looks like there's a problem with the UF website, does anyone know what's up with that?

PS. If you have a Facebook account (I don't) you could try messaging Frederik about this in case he is not aware of the problem?

Oh dear, yes, it looks very much like the whole website has gone from that server. No, I disagree!

For the moment I'm not overly concerned - there have been times in the past when things have temporarily gone down at ultrafractal.com and it's always come back. I suspect there is either problem with the hosting server or possibly Frederik has decided to move his domain elsewhere to another provider. Sometimes things like domain transfers can take a few hours or even a couple of days for the DNS servers to propagate the changes and catch up. I'll try again later... or tomorrow. *shrug*

I can't view the FB page since I don't have an account. I'll wait, hopefully things will sort themselves out.

I note that the caption for the fifth choice of gnarlic formula in Gnarlathotep 3 reversed version 2 doesn't make any sense (it is a leftover from when I was making the modifications). I have adjusted the text and uploaded the revised formula onto the UF data base.

Thanks for your note, Evan. I have now got the updated formula and can see the correction to the text has been applied. The wording was a bit garbled but I expect most users will nevertheless have got the idea about it being the fifth gnarlic option.

I hope we can all have a bit of fun exploring this formula of yours! Let's see what this month brings in terms of challenge entries. :D (Big Grin)

Getting back into using this site and I'm running into a snag.  When I attempt to upload my parameter files to my sta.sh page I keep getting the error that HTML files are not allowed, even though that's clearly not what that is (double checked in the file's properties window just to be sure).  Is this a known error or am I doing something obvious wrong?  Thanks muchly to anyone who can help.

I am under the impression that with ECLIPSE the STsSH now accepts only ZIP files. Try putting your parameter files into a WORD document or something similiar, and then putting that into a ZIP file and then upload it into your STaSH. Let me know if that doesn't work. Good luck!

Welcome back to the site and to Ultra-Fractal-Redux - it's so nice to have a new face on board! Yeah, it's a known error, unfortunately This has been going on for ages, ever since they started tinkering with the new DA interface. No, I disagree! 

My workaround is to first upload either a thumbnail of the work -or- a placeholder image of some kind like a UF stamp. Anything will do. With that in place in your stash you then hover over your new thumbnail and choose "View". Now you can add your params in the Description area beneath. When done just close the tab or navigate back to your general Stash area - just do not try to "Submit" or you may inadvertently make it go live on DA, which you don't want. From your Stash area you can now click on your thumbnail again just to check everything is in order and to grab the URL for sharing alongside your *real* image on DA.

This all sounds more complicated than it really is. Basically you are just saving an unsubmitted image (your small thumbnail/placeholder) in your stash with your params in the comment area below.

Here is an example of one of my parameter sharing stash items so you can see what I've done:
