Can anyone tell me the name of any software/books that teach or experiment with the concept of fractals? I would sincerely like to learn more about this an hopefully incorporate it into some on-the-fly animation programs, eventually, that I am developing for my war-games club.. Thanks for any info...

Someone asked for a program that creates fractals on an Apple //. You can get one for $3 by writing to me: Michael de la Maza, 10 Tumbleweed, Irvine, Ca 92715. As for creating fractals on the fly -- dream on. My program takes **hours** to create a full-screen fractal. Maybe i'm just a terrible programmer.

Sintar Software advertises a program called FractalMagic for the Apple II, Mac and IBM for $25. I have no idea how good it is, although Jerry Pournelle gave it a plug. They can be contacted at 206 455 4130 -- they take charge cards. Address is PO Box 3746, Bellevue, WA 98009. ARPA: stein%uconnvm.bitnet@cunyvm.cuny.edu Alan H.

Can someone send me a program for the //e that will make some fractals?
Thanks,

I'm a complete novice as far as graphic technology goes. Can someone please
explain to me what fractals ARE?

Replace all of the &commands with the standard hi-res plot commands.(use HGR2, not HGR) Change the line which says CL=K-INT(K/15)*15+1 to read CL = INT(K/2)*4+3 (I may have changed it so that there's a Palette size where the 15's are - I can't remember..., if so, change the line to read as above anyway) Change the number of colors to be, say, 100 or less (to make up for the lack of speed). Change the MaxX and MaxY to 279,191 (these are currently set to 319,199). Change the FOR-NEXT loop counters as well (if they aren't set with MaxX, MaxY). This should make a black-white Mandelbrot on Hi-res page two... Please pardon the vagueness of this reply, as I don't have the version I sent out in fromt of me...Basic overview: if you want to change this to work on anything else (the program is very general) all you have to do is a) change the graphics commands b) change the MaxX and MaxY (these are the screen dimensions - 1) the two lines that use this are : DX, DY calculation (divide by MaxX,MaxY), and the FOR-NEXT loops c) change the color scheme (this is the change from CL=... to the new one. It is needed when a change in palette arrangement or number of colors occurs) d) change the number of colors simulated to account for the speed of the machine. Hope this helps...good luck.

While Mandelbrot sets are sort of interesting to look at, fractal mountain generators have always seemed a bit more exciting. Has anyone out there come up with such a program (either II or IIgs)? Please don't give lists of interesting books... I've been through comp.graphics already. -- laba-4an@widow.berkeley.edu (Andy McFadden)
