RE Color maps in the latest FractInt
by Knute 20 Oct '17

20 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 .

A full screen video mode will not behave as expected (like DOS Fractint) when a new video size is selected using <DEL>. I had tried to implement it, but was having trouble determining the causes of the problems we were (and still are) having with the different video modes, so I took it out. Once switching normal window sizes works, I will work on getting <DEL> to work when the image is full screen. OTOH, we could have the <DEL> selection reduce the window size to be not full screen. Any preferences? Jonathan

Did you move the executable? The zip file has a new SDL2.dll file along with an updated fractint.hlp file. If you are moving the executable, since I updated the version of SDL2 I was using, the SDL2.dll would need to be moved also. If you didn't move the executable (without the new dll), I have no idea what the problem is. I will try to recreate the problem in a test directory. Jonathan

So I have to drag it back up (for upper left corner of > screen) to make the whole thing visible. You have a video mode in fractint.cfg with a key code of SF10? You can set the default window size in sstools.ini. It is currently set for 800x600 (unless you changed what SF6 means). In your case, use the xfractint entries. > What would be the correct aspect ratio for 1920x1080? 0.56? Define correct.

Anybody know how to change COLOR.MAPs in Jon's latest FractInt (SDL2-fractint-20.05alpha-2017-10-15)? I just installed it but find that it crashes every time I try to change to a different color.map... every time I press "C", then "L". "E+Enter" brings up the Color Editor just fine, but I can find no way, no keystrokes to bring up the Maps Folder. I don't recall having this problem in Jon's previous 2 versions. Any suggestions?

Folks, I've updated the SDL port to not crash as often when changing image sizes. The Windows version sometimes provides a blank screen because it thinks the parameters have changed. Toggling the <F> key (floating point) will get the image to generate. The mouse zoom box behaves a little differently in that it will now change size in the direction the mouse is moving. I am working on a 64-bit Windows version, but it doesn't want to link. Windows version (32-bit) is: https://fractint.net/ftp/experimental/SDL2-fractint-20.05alpha-2017-10- 15.zip Pre-compiled 64-bit Linux version is: http://www.fractint.net/ftp/experimental/SDL2-Xfractint-20.05alpha-2017 -10-15.tar.gz or look in the directory: https://fractint.net/ftp/experimental/ Jonathan

New Fractal Music from Albrecht: "Contemplation, & Contrapoints"
by Harold Lane 14 Oct '17

14 Oct '17

After I posted Albrecht's new fractal music pieces: "Contemplation," "Contrapoints" and their source fractal, "move3", he said: 'I would like to add the original source image "move" '. Here are links to a JPG version of that original source image: http://tinyurl.com/Original-source-image-move or: http://www.emarketingiseasy.com/Albrecht/Music/221014-Hurricane3-Move.jpg I also have the ~3MB .BMP version if you need that format of the image... - Hal Lane ######################## # hallane(a)earthlink.net ######################## --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
