I have written a program that simulates waves by creating a grid of
'masses' attached to 'elastic strings'. Then for each mass, I take
its differential elevation from each of its neighbors and relate
a force vector to it. Then I derive the acceleration (F = mA) and
integrate the acceleration to get the velocity, and that to get the new
position. I do this for each mass and store the new position in a new
array, redraw the 'grid' to the new values, and start over again. The
program that does this is called 'Vibra' and runs on the Amiga. It is
available from me(!) or you might find it lurking on a Amiga BBS somewhere.
If anyone is intrested, I will upload it and/or the source code
here. Leave me E-mail or call me at (215)228-7490.
