Hi there,

I need some help to calculate the moment of Inertia of a Shape with N
EdgePoints.

There's a neat solution for that. See

Brian Mirtich, Fast and Accurate Computation of Polyhedral
Mass Properties, Journal of Graphics Tools, volume 1, number 2, 1996

It's a simple algorithm, and widely used. The usual version is 3D,
but you can reduce it to 2D.
