Interference
Run a check to detect clashing parts.
Interference = AABB broad-phase, then a Monte-Carlo estimate: points sampled in the overlap box, tested inside both solids by ray-parity. Clash volume is an estimate (denser sampling = tighter). Mass by the divergence theorem over each transformed part.
