In order to create a source package of the SDL version that can be compiled, I will need to create a Make file. Since I am developing in an IDE, I haven't done this yet. If by package it is meant a pre-compiled 32-bit version, then no, there is not one available. Although I am doing it now for the 64-bit SDL version, I prefer to not distribute pre-compiled versions for Linux. There are too many variables from one distribution to the next, and I can't guess what they all may be (or cause). Jonathan

If I last edited them under Linux, then the End Of Line coding could be incorrect (LF vs CR LF). I'll have a look at it. I will also start zipping the Windows version files differently to see if that makes a difference in how the executable behaves. Jonathan

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

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 21 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.
