I know this is OT, but here are a lot of people coding technical applications.
I need to find the principle axis of inertia of a tetrahedron. Does anybody of you know a formula how to get this?
Thanks,
Kilam.

Do you want the inertia tensor, or what?
A symmetrical object obviously has no unique principal axis of inertia.
See http://www.cs.berkeley.edu/~mirtich/massProps.html
for code for computing the inertial tensor of a polyhedron. It’s a neat little bit of math by Brian Mirtich.
Thanks! That looks good.
