Is there a standard way to store 3D meshes to easily communicate between libraries?

3d-meshes

In a 3D game lots of different systems need to know about geometry data, however the only way they seem to be able to agree to on in representing it by an array of triangles.

Can anyone recommend a good geometry manipulation library that will allow me to easily integrate the drawing library(OpenGL), the physics engine(Bullet), Serialization(Several 3D file formats) and my own code(objective-c++). Focus on the a representation between the drawing library and the physics engine. Also if the library can triangulate a mesh definition that would be very helpful. My code can work around what exists already.
