Update 12-26 to SDL version
by Jonathan Osuch 31 Dec '17

31 Dec '17

Folks, Fixed image browser crashes. Fixed windows version use of long double. There is still a problem with input/output of the long double type, but the ML219-X3.GIF image should generate correctly now. Windows version (32-bit) is: https://fractint.net/ftp/experimental/SDL2-fractint-20.05alpha-2017-12- 26.zip Pre-compiled 64-bit Linux version is: http://www.fractint.net/ftp/experimental/SDL2-Xfractint-20.05alpha-2017 -12-26.tar.gz or look in the directory: https://fractint.net/ftp/experimental/ Jonathan

Hi, two rather unusual images today together with PAR and FRM: ; https://1drv.ms/f/s!AmWYApv7ZBFG5zWpMnXnKgmfT9x5 ; I still stick to the Oracle VirtualXP as it has several important advantages: It is a complete XP system with Firefox, Thunderbird and the one and only Winamp player5. has it´s own download folder and is very fast. Also the complete collection of Fractint images and formulas, thousands of images to zoom and explore. And it is Freeware, incl XP Image, A N D it is safe. Since more then a year I have not seen a single malware attack so I dont need an Antivirus or any other protection tool. As I see it, it´s protected by the Win10 tools and by it´s incompatibility to earlier windows versions. Albrecht

MsetRoots formula by Edward Montague - images

Quickie post with a screencap of Edward Montague's MsetRoots formula's parent fractal with Sebastien Helie's color map with contrasting adjacent colors -- to try and get an initial look at the fractal's structure: http://tinyurl.com/MsetRoots-parent-fractal-jpg or: http://www.emarketingiseasy.com/Sciwise/171210-MsetRoots-parent-fractal.jpg I couldn't help but explore a tiny bit...

Edward, In the documentation for the formula type (from a formula type, press F1), you will find the following: NOTE: For periodicity checking, inside options, outside options, and the passes=o option to work correctly it is necessary to leave the result of the orbit calculation in the variable z. You would want to use z instead of z2, in the formula below.

This can be done like this: R1Mandel(XAXIS)[periodicity=0] {;sciwiseg , Edward Montague ...

I really like this parameter file. If you run it and then go to the <p> screen, when you set the orbit delay to 10, the image starts to look vaguely like Rolf from the Muppet Show. Jonathan

Hi, sometimes the angels scream or is it because of xmas time ? Anyway I have moved something and the OneDrive problems have been solved. Thanks to the person responsible ! As my gift for you here is a general link available for the community ; https://1drv.ms/f/s!AmWYApv7ZBFG5TA8f8moLCmVChuD ; For your info: there was a new Win10 update today with several restarts and this was the first update I noticed, apparently all items reloaded.
