Using OOBB's would be acceptable here for me, but they are not

but calculating OOBBs is computational a very expensive operation. Using
them can only be an option if you precompute them and do not change
objects.
I am using rigid-bodies, so I am able to precompute.
The problem is that I have some very thin and long objects that can be
arbitrarily oriented, and neither Spheres nor AABB encloses these
objects efficiently enough. I believe I need some object-oriented volume
types for this.
I'm using these volumes for some application-specific logic, which needs
to be resonably fast & somewhat accurate. Also Triangle<->Triangle
collisions are a bit overkill for this.
