I can't explain this. The video interface is not as robust as it should be. (duh!) Jonathan

Re: [Fractint] Is there a Linux 32 bit version that I might try?

SciWise, (copy to Jonathan Osuch), > Is there a Linux 32 bit version that I might try? > Preferably as a package . This directory has a 32-bit (I believe) Linux version: https://fractint.net/ftp/current/linux/ But, I think you'll have to compile & link it... (My understanding of packages is lacking. I'm not familiar with Linux.) The read.me says: ---------------------------------------------------------------------------- --------------------- Download the source tarball (for example: xfract20.3.02.tar.gz), put it in your home directory, and untar it with the command: tar -xzf xfract20.3.02.tar.gz This will create the directory xfractint-20.03p02 containing the source. You might want to change the directory name to xfractint for convenience. You will need to have gcc, ncurses, and ncurse-develop installed. You also need the XFree86-libs package installed for the X11 libraries. This package should already be installed, but if it isn't and your distribution doesn't have it, then you need the XFree86-devel package. The Makefile is set up for my convenience, so if you want to put files in different directories, you will need to change the SRCDIR setting. Otherwise, just run make from the source directory and it should compile. Run ./xfractint to start it up.

Simpson integration for iterated function
by Edward Montague 26 Oct '17

26 Oct '17

After noticing the structure of the Simpson Integration Formula I realized that for interated functions this simplified somewhat. The two formulas are simpf1 , for Mandelbrot Set , and simpfn1 for a general function fn1 . Simpson integration is a low order approach , therefore most of the fractal structure of the iterated function appears to be preserved . simpf1(XAXIS) {; sciwise ; Simpson's integration applied to f1. c = Pixel s = 0 x0 = c x1 = (x0*x0) + c x2 = (x1*x1) + c : s = s + (x1 - x0)*( x2 + x1) x0 = x1 x1 = x2 x2 = (x2*x2) + c z = 0.5*abs(s) |z| < 40000 } simpfn1(XAXIS) {; sciwise ; Simpson's integration applied to f1. c = Pixel s = 0 x0 = c x1 = fn1(x0) x2 = fn1(x1) : s = s + (x1 - x0)*( x2 + x1) x0 = x1 x1 = x2 x2 = fn1(x2) z = 0.5*abs(s) |z| < 40000 }

Re: [Fractint] Update to SDL version

Folks, I updated the maximum path length to 512 characters. The zoom box using page-up and page-down can now be rotated and skewed. Changing windows sizes should now auto regenerate the image. There are still problems with changing to full-screen with the Linux version. It may be due to differences between version 2.0.4 (Linux) and 2.0.6 (Windows) of SDL2, or it could be something else. In both Linux and Windows, changing back from full-screen to a window using the <DEL> key generates the correct sized image until you move the window, then it reverts to the size you had it before you changed to full-screen. Windows version (32-bit) is: https://fractint.net/ftp/experimental/SDL2-fractint-20.05alpha-2017-10- 22.zip Pre-compiled 64-bit Linux version is: http://www.fractint.net/ftp/experimental/SDL2-Xfractint-20.05alpha-2017 -10-22.tar.gz or look in the directory: https://fractint.net/ftp/experimental/ Jonathan

My mail isn't being forwarded to the group . One message went through a few days ago ; now this isn't possible . I'm wondering if this is a consequence of my present email provider using antiquated and incompatible software for their mail system . Anyway I'm moving over to gmail , do you experiende problems with that provider ?

Re: [Fractint] New Fractal Music from Albrecht: "Contemplation, & Contrapoints"
by Albrecht Niekamp 22 Oct '17

Sorry for late reply due to hospital stay. Love your mp3 versions. As the main title is move3 I´m working on a final third part. If you´re interested: The moving effect is created by playing every other left note with the riht hand VV. The left-right effect is unchanged as the midi output channel remains. Tell me if you want some details about natural music, combined with the latest version of the fractal rythm. It IS something different.

RE Color maps in the latest FractInt
by Knute 21 Oct '17

21 Oct '17

Thanks Jonathan for responding to my problem with bringing up Fractint's Maps Window with <c> <l>. Preassing <c>, <l> caused the 3 latest versions of Fractint to crash, and then it got worse: I could not even open any of the 3 latest versions (they would immediately crash before completely opening). Well, I just downloaded _SDL2-fractint-20.05alpha-2017-10-15_.zip once again, unzipped it and left the resulting Folder right there in my Downloads Folder. From it I opened Fractint no problem, and I pressed <c>, <l> , brought up the Maps Folder and changed color.maps no problem. So apparently the crashing problems arose because I had MOVED my Fractint Folders (I consolidated all my Fractal stuff residing in Downloads into one Fractals Folder... thus they were moved after I had unzipped them). Note: by 'moved' I mean that I moved the originally-unzipped Folders containing Fractint.exe, SDL2.DLL, etc.; I did not move the .exe or .dll out of their original Folders. So, it looks like I would not have had any crashing problems if I had not moved the _SDL2-fractint-20.05alpha-2017-10-15 Folder_ after unzipping it. At least, my latest re-download tonight is working fine. Thank you Jonathan!

I just tried this in Windows 10 several times with no problems. A more plausible explanation may be that the path (from the root directory to the executable) exceeded 256 characters. This is hard coded and doesn't fail gracefully. I will increase this limit. A month or two ago, we were seeing a similar problem with putting the folder on the desktop in Windows. This has been fixed. The problem was that there were some buffers overflowing. We could be seeing it again. Jonathan

Equation for fractals at quantum level
by sciwise＠ihug.co.nz 19 Oct '17

19 Oct '17

Observing and simulating quantum entanglement , tends to show that fractals are what's involved . In particular what appear to be Julia sets. Just wondering if anyone has access to an article that contains the equation that describes all of this . This appears to be an extension of a decade and a half earlier article on the fractal nature of electron orbits .
