I calculated some different sizes of (and also varied "float=" on) Mr Helie's November 3, 2011 "7dimcful" 'seven dimension image' using DOS Fractint version 20.04.4 I don't know what the behavior of Fractint is when there is no bailout test specified, so I don't know how the program determined when to stop iterating -- perhaps it silently traps overflow and then moves on to the next pixel calculation. Anyone know what Fractint does when a bailout test isn't specified? <---<< To try and zoom out as far as possible -- to show a parent fractal, I first used "float=y". With float=y the fractal appears infinite in extent. Three images are anti-aliased. Be sure to click the image to see it full size.

His original fractal calculated with passes=1 is here: http://www.emarketingiseasy.com/TESTS/FOTD/7DIMCFLO.GIF (Which is similar in magnification to 7DIMCFLN.GIF above.) - Hal Lane ######################## # hallane@earthlink.net ######################## ======= Sebastian Helie's 7dimcful ============================== 7dimcful { ; Use to be a seven dimension image ; now probably only 4 ; a excelent star source. ; for my master.
