You may be trying to do this in a way that is more difficult than it
really needs to be. As someone pointed out, the model could be a
separate application, called from hypercard, and the contour animation
might be another separate app. We are doing exactly this sort of thing
with a tree growth model. We use hypercard as a front end to aid the
user in setting up the model run correctly and to provide online
documentation. The model itself is a combination of Fortran and Pascal
using MPW, and finally there is a pascal program to display the results
in fancy color graphics. This works out nicely because the programs
can be launched from HC and we are not asking more of these development
systems than they can handle.
Also, I wanted to mention that a meteorologist here at Cornell has
developed a program that reads data files and generates animated
contour maps on Macs. It is called MacStorm and may be in the
Kinko's catalog by now. My understanding was that it could interpret
data of different kinds and generate the contours. A separate program
did the number crunching of the weather models and generated the data.
Send mail if you need his phone # or whatever.

BTW, Please let me know how your solution works out. It sounds like an
interesting problem.
