You're right about that.

There's also the precision thingy we've talked about
months ago, remember? That my non I/O calculates
an impact with the boundary box, while your I/O
one approximates it with trace() calls. I doubt that
the precision of your system is so much a drawback
though.

But one thing I've noticed and that is probably fitting to
mention here:
I've noticed that the interpolation in between frames
doesn't yield smooth flying curves, but rather straight
connections. Is that still an issue? I'm not sure how that
could be solved anyways, I haven't given much thought
to it. Maybe I'm even wrong, since that was a looong
time ago.
One solution is of course to calculate more frames, but
is there an alternative to that?

Regards,
Tim
