Miscellany/!4dMandia/docums/ReadMe
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

Documentation for !4dMandia application. ---------------------------------------- This is a four dimensional Julia and Mandlebrot set plotter. It takes a 2 dimensional slice out of a 4 dimensional plane. The four constants q0-q3, and the starting values c and d determine which slice. The program was originally designed as a 4d Julia set plotter; the 2d and Mandlebrot options where added later. The Julia set does not increase in detail when one zooms in (as does the Mandlebrot Set), so the program has limited resolution. A small speed increase is possible for the 2d options, but I can not be bothered to add it as the programming time will not justify the small speed increase. There are many features, to find out how to use them read Instruct. Happy plotting. PS If anyone has any ideas/improvements/bugs(!) do not hesitate to drop me a line. If enough improvements are added, then I shall send in the new version to AC. Do not expect anything for a few months though.
