uh-oh. I'm afraid that you need to make a loop, then perform a static
cast on each element, then check the member variable (be it velocity
or position).

MetaInteractingGeometry2AABB.cpp checks for min/max bounding volume,
so you can look there. It is a bounding volume of whole scene.

yade-package-common/src/Engine/EngineUnit/MetaInteractingGeometry2AABB

Your loop will look similar.
