FOTD 24-05-02 (Hexagons and Circles [7])
FOTD -- May 24, 2002 (Rating 7) Fractal visionaries and enthusiasts: To begin, I will answer a few questions about the FOTD CD that must be causing unlimited concern to the members of the list. :-) Q -- When will the CD be ready? A -- Before the end of (northern hemisphere) summer if all goes well. Q -- Will there be a charge for the disk? A -- Yes -- blank disks are not free. Q -- How much will the charge be? A -- I haven't decided. Q -- Will the disk have a graphic-user-interface? A -- At this point, no. Q -- What kind of indexing will the disk have? A -- That depends on how much time I have to work on it. Q -- Will the Fractint program be included on the disk? A -- Probably not. The notice that the program may not be sold is still at the bottom of the Fractint opening credits screen. And those who would want the disk will probably have a more recent version of the program by the time they receive the disk. Finally, those who have recently discovered fractals have probably done so with one of the Windows programs, and would have little interest in a DOS program. The disk is intended to be a convenience rather than a commercial success. Q -- Are the above answers fixed in stone? A -- No! As for today's image, I must confess a bit of thievery. I found today's fractal image while noodling with a formula named Klein_tri_lattice that was posted recently to the Fractint list. I have no time to check through my old mail to see who wrote the original formula, but I give thanks regardless. Since the formula has no changeable parameters, what I have done basically amounts to tweaking someone else's fractal. Normally I never tweak the images of other fractalists, but today's tweak makes such a striking image that I could not keep it to myself. I named the image "Hexagons and Circles". I gave it this name because the densest packing of circles in a plane is in the shape of a hexagonal grid. The rating of 7 seems appropriate. With a run-time of under five seconds on most machines, today's parameter file is one of the all-time fastest. The completed GIF image will still be available for quick download on Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and on Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> With total sun and a temperature of 77F 25C, the fractal weather Thursday was ideal for man and cats alike. The man spent the day working; the cats spent the day resting and having fun. Today promises to be a repeat, so I'd best get busy with the work. Until Monday the 27th, take care, and see you then.

I believe it was Morgan L. Owens on Thursday, 23 May 2002 01:28:28 +1200 Sincerely, P.N.L. -------------------------------------------------------------- http://www.fractalus.com/cgi-bin/theway?ring=fractals&id=43&go
