I am afraid it doesn't exist due to the graphical only nature of OSG. However, OSG still offers some very useful tools when dealing with the objects, as model loading. That is what I am currently doing in my project through the use of the Nodevisitor and TriangleFunctor classes. > I have used the one from UNC in the past.

Cache or extract the geometry at start would be the best since it allows to build data structures that will speed up your collision tests at runtime (AABB trees and so on).
