Serialize a mesh

Hi,

I am currently capturing a user mesh from a Kinect (I am making a mesh by subsampling the user depth map). I would like to save the frames to a file in order to reproduce them in another context. My first approach is serialization. Apparently, all objects in my graph should be serializable, so I am asked to serialize the Mesh class, the Vector3 class, and so on. Is there another way to do this?

My current approach is having a Frame class which simply contains a timestamp and a mesh. I construct a List of Frame objects and I attempt to save it when the application is closed.

[A note to moderators: I would appreciate some feedback if this question gets rejected...]
