hi slim,
I am experimenting with the physics feature of Fluxus and running into
issues where the primitives are vibrating (very jittery, I should
say).
i think a small amount of jitter is almost inevitable. you can try
experimenting with the surface parameters. read more about them on the
ode site here:
http://opende.sourceforge.net/wiki/index.php/Manual_(Joint_Types_and_Functions)
setting softcfm to 0 and softerp to some small amount might help.
something like (surface-params .1 .1 .2 0) seems more or less fine to me.
best,
gabor
