I put the pre-compiled 64-bit Linux version on the developers web site as: http://www.fractint.net/ftp/experimental/SDL2-Xfractint-20.05alpha-2017 -10-08.tar.gz Jonathan

Folks, I've updated the SDL port to support the palette color editor. Use the cursor keys, since the mouse support is unusable at this time. Disk video modes other than 2-color modes work now. Video modes (other than disk video) larger than the current screen size will now send you back to the video selection screen. https://fractint.net/ftp/experimental/SDL2-fractint-20.05alpha-2017-10- 08.zip or the directory: https://fractint.net/ftp/experimental/ Jonathan

I did get my Linux development environment working again. The Linux version of the SDL port works with some differences. The 2-color disk video modes run with no problems. The large disk video modes in fractint.cfg run in computer memory and not using the hard disk. Jonathan

Folks, I've updated the SDL port to support color cycling. The color editor still doesn't work. I added disk video modes for the largest sizes supported to the end of fractint.cfg. If you want to be able to run them more than once before having to restart Fractint, assign them to key codes (like AF6 & AF7). I am working on fixing this. https://fractint.net/ftp/experimental/SDL2-fractint-20.05alpha-2017-10- 01.zip or the directory: https://fractint.net/ftp/experimental/ Jonathan

Re: [Fractint] REquest for a lil basic FractInt info

Knute asked: ...I miss FractInt; I am only able to use Windows 7 (64-bit). My question is this: As of October, 2017 is it really still impossible to run FractInt on Windows (esp. Win 7)?... (Not "virtually" and not WinFract). Timothy Wegner replied: Jonathan (Osuch) has rebuilt Fractint using the SDL library, and this versions does indeed run natively under Windows 10. Knute: Thanks very much Timothy for responding! Although I do not have Windows 10, I rushed to download the file you designated (SDL2-fractint-20.05alpha-2017-10-01.zip) to try it on my Windows 7. The result: The Fractint.exe file opened a small window labelled "Fractint" at the upper-left, but no Menu, no controls whatsoever. Right-click did nothing - no dialog, no controls. The small window was resizeable, but after re-sizing it a couple times the program crashed. What this program DID do was show a picture of a basic Mandelbrot, and a Left-click-drag resulted in Zooms. Lastly, I opened the included FRACTINT.HLP file in Windows but it was empty. Then I forced FRACTINT.HLP to open in Fractint.exe. All that did was to open Fractint. AND THEN I REMEMBERED TO OLD "F1" KEY in ancient FractInt! So, with Jonathan Osuch's FractInt open I pressed the F1 key and VOILA! there was FractInt (all the controls). *_So it does work in Windows 7!_* *_So it does work in Windows 7!_* *_So it does work in Windows 7!_* (If only someone had mentioned the F1 Help Key at the first. Hope it goes into your FAQs.)

REquest for a lil basic FractInt info
by Knute 02 Oct '17

I loved FractInt since 1994-5 when I got my first PC. Now I just miss FractInt; I am only able to use Windows 7 (64-bit). Yes, I tried to install a Linux a few years ago but gave up. I also did try out two Virtual things when I was using Windows XP so I might have FractInt, but they were unsatisfactory and FractInt kept crashing. My question is this: As of October, 2017 is it really still impossible to run FractInt on Windows (esp. Win 7)?... (Not "virtually" and not WinFract). If so, then... If you were me, stuck with only Windows 7, then would someone kindly suggest how you would get FractInt to run (even if it has to involve some virtual program)? Thank you much for your time!

Update to SDL version

Folks, I've updated the experimental SDL version on the Developers website. It now runs a disk video mode, but only once, then it crashes. Jonathan

Galactic Amoebas

This fractal is one I found in 2016 while experimenting with one of Jim Muth's favorite formulas, the FinDivBrot-2. The formula makes nice fractals and I was interested in seeing what it would look like when used with the parallel resistor formula that I have posted here many times before. Jim's original formula with a = -1 in simplified form is: z = b * z * z / (1 / z + b) + pixel Using it in the parallel resistor formula, rp = 1 / (1/r +1/r) I got. z1 = b * z * z / (1 / z + b) z = 1 / (1 / (z1 + c1) + 1 / (z1 + c2)) You never know if something like this will make an interesting fractal without trying it. Since I was just exploring, I used Jim's original color map. You can probably guess what happened. I found this fractal that I liked with Jim's colors. I couldn't change it without losing the nice green galactic nebula appearance. So here it is with Jim's original color map unchanged. You can see an image on the Fracton web site at: http://www.fracton.org/fmlposts/galacticamoebas.html Hal Lane and I explored many other fractals in this formula. It tends to make a lot of fractals with tendrils. A few are visible at the boundary between the green and the black along the left side in this image.
