Hi all, Any thoughts on calculating the 'wetted area' of an object, e.g. the part of a boat that's underwater? I'll need to know where to apply rigid body buoyancy forces, which makes things harder I suppose. I'm thinking maybe bounding-box - plane intersection manifold? But the info I need may be hard to extract from this. Or possibly cast N rays down from the top of the box into the sea..?

Oh nice links u 2. That'll teach me not to search for 'wetted' ;)
Looks a bit more complex than I first thought, as usual.
