i found that Mathematica 4.0 running on a >1ghz pc still chokes generating multiframe TIFFs. however multiframe GIFs seems to be ok, though they are limited to 8bit. here's examples of the animations i'm generating http://vorlon.cwru.edu/~axc/Thesis/Animations/Data6a/ http://vorlon.cwru.edu/~axc/Thesis/Animations/Data2h/ - in case you're wondering what these are i'm studying phase-locking in so-called hybrid oscillators which have piecewise constant vector fields but with switching and control discontinuities. so, e.g., the avi's in Data6a show the same controller parameters at two different robot speeds showing legs locking to different gaits, consistent w biological data. email me if you have more questions alan calvitti axc at eecs.cwru.edu >gleam at flashmail.com writes: > > Alan, there is a much easier way!
