Hi Richard, > Oh sweet! I will go through these. It looks like you didn't keep > Jim's little essays for some of them. Oh well, the pars/frms are > better than nothing 🙂 I didn't think we preserved the essays in the par archives. You may have seen various FTOD compilations that exist that have them. Paul Lee had one going, the links don't work 100 percent and many times the image wasn't preserved. But I'm encouraged at how well this works at all! http://home.att.net/~Paul.N.Lee/FotD/FotD.html It's a shame that 20 years ago it was about about preserving disk space. I probably has a lot of the essay's in the xmission Fractint Digests but wasn't saving them. Now that feels foolish! > Oh, lots of archived goodies there, thanks. Some of these programs > were in danger of being lost to the winds of time. I have uploaded > tierazon and flarium to github and a couple others. I don't know if you've seen Paul's main page https://web.archive.org/web/20090815013739/http://home.att.net/~Paul.N.Lee/ and his software list page. What a job he was doing! https://web.archive.org/web/20090909005540/http://home.att.net/~Paul.N.Lee/… > However, there are two variants of the formula parser/interpreter. > There is the assembly language verison used by the DOS code and there > is the C language version used by everything else.

I wonder if the writer knows what's up with it or perhaps the program has the same problems there. > Oh, that's good to know about the duplicate name problem.

This was an attempt at a grand compilation of every for forumula that ever existed! https://web.archive.org/web/20090909113555/http://home.att.net/~Paul.N.Lee/… I see there is at least one github compilation of it. https://github.com/fract4d/formulas I have what I think was the last version of it in its original file format to download here. (The Jim Muth formulas were the last entry). There was a way to hook this into Fractint I think. https://interocitors.com/tmp/fractals/ORGFORM.ZIP Sorry if I'm telling you things you already know :) Roger

Hi Richard, Les St Clair used to make par files by year, and then I contributed some. His site is still in wayback but many of the later lists were never posted. The last backup of his site was https://web.archive.org/web/20190311231709/http://www.les-stclair.co.uk/fra… The pars I compiled start on April 12, 1997 and end on April 11, 2008. These dates were of JM "fiscal" year as it were. I uploaded the complete set of the files here to make it easier (1.7 mb). I have checked and you have some missing days here and there. You might just be able to process these if you want. You're pretty good at github I see :) https://www.interocitors.com/tmp/fractals/FTOD.zip Roger P.S. you are posting that sometimes the ID image comes out different that Fractint. Is it possible it is using a different formula? One of the biggest problems I had with Fractint was that they didn't force the formula names to be unique. In the orgform database they had "dup" lists for each letter of the alphabet.

FOTD pars uploaded to github
by Richard 24 Apr '24

Hi fractal fans, I've uploaded all the PARs I have for Jim Muth's Fractal of the Day series to github. This includes some 1997 PARs that I found which I haven't yet rendered into images on the web archive. The PARs are here: <https://github.com/LegalizeAdulthood/fotd> From there (using the "Code" button) you can download a ZIP of all the PARs, which is simpler than downloading individual PARs one at a time. If you have any missing PARs (2002 or earlier), I'd love to get a copy of them so that I can fill in missing dates.

Hello wonderful people of Fractint. I wanted to make you all aware of a new image to fractal algorithm developed by lookingglasstoinfinity.com . Please take a look at the blog section for a detailed description of the algorithm, what it does, and applications. Please send any questions or comments. Thank you! https://lookingglasstoinfinity.com/blogs/news/beyond-the-visible-pioneering… https://lookingglasstoinfinity.com/blogs/news/fractal-algorithm-application… Sent with [Proton Mail](https://proton.me/) secure email.

high-resolution archive of Jim Muth's Fractal of the Day restored
by Richard 08 Apr '24

Hi Gang, A while back I was producing 1600x1200 renderings of Jim Muth's Fractal of the Day in an automated fashion. They chewed up some disk space on my personal web page, which was limited at the time. So I had old images rolling off after a period of time and they were archived some place inaccesible from the web. Now my personal web space quota is sufficient to host the whole archive again, so I've restored them from the archives. This is every FOTD image posted from June, 2002 to July, 2014. The PAR files include the text of Jim's email. <https://user.xmission.com/~legalize/fractals/fotd/index.html> -- Richard -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Terminals Wiki <http://terminals-wiki.org> The Computer Graphics Museum <http://ComputerGraphicsMuseum.org> Legalize Adulthood!
