Origin to footprint

Origin to object footprint (origin goes to the center of a circumscribed sphere around your object, as an alternative to origin to geometry). I really wish I could move an objects origin to the center of its footprint, especially when I have "lopsided" geometry.

Would be good to have in order to quickly snap to face object. Useful when placing many props on the ground, or on shelves, tables etc...

Idk how it works but it's open-source. I suspect they're just doing a 3D convex hull

This seems like a very arbitrary thing. Wouldn't it be better to use origin to volumetric center ? since you can do some quick calculations using octrees and quickly determine it and this would serve the purpose of finding the center of mass of an object ( assuming homogenous materials ), which would be useful for animation since the COM is usually the pivot of free rotation. edit: obvious drawback would be that this would only make sense on manifold geometry
