Has anyone read the Mathematical Recreations column in last months Scientific American (Sep 1991)? They describe Lyapunov space. This is yet another chaos representation whose images look very interesting. They present an outline of the algorithm for generating these images, but are rather vague on a couple points. I've tried various interpretations to little or no avail. If anyone has read this column, could you give me your interpretation of the algorithm? I'll post any code I get working (warning: it takes over 3 hours to generate a 320x200 image on a 28MHZ 68030/882 using strait 881 FPU instructions!) john

| 5065.1 | Is that like Lyar's dice? | SDOGUS::WILLIAMS | TOPGUN | Tue Sep 24 1991 16:28 | 10 |
JOHN,
There was an example uploaded to CompuServe of Lyapunov space. I'll
try to find it and upload it for you. There is a screen blanker
available for WB2.0 which purports to use Lyapunov space to generate
its screen images (it is fairly fast and it is not a complete Lyapunov
space image). I think it is called FRACT.LZH. I'll look for that as
well.

| 5065.2 | blind spot | STAR::GUINEAU | but what was the question? | Tue Sep 24 1991 17:20 | 16 |
I got lots of info from the alt.fractals (usenet) news group. I actually had the program coded corectly, but was feeding "improper" ranges of parameter values (this is what was vague in the SA article!) annd expecting to get the images they had in the article. I have since gotten many interesting images. I'm adding functionality and cleaning things up at this point. I'll shoot for posting something this weekend (If no strange attractors get me otherwise that is :-) ) Right now I just generate 24 bit DigiView "IP" files and let DigiView do the image processing (what a program!). john | |||||
