How to get btShape volume?

[irrmich]

I wish to implement a water with buyoancy using concaveConvexcastDemo code, but i need to calculate object volume, and object mass to use archimed formula. Someone knows?

Finally, i'm going to aproximate the mesh shape volume using the bounding box of the shape waiting for a better algorithm

I have some code that can compute the volume, center of mass, and inertia tensor of closed meshes and I've been looking for an excuse to clean it up and submit for public use. I'll try to get around to it, but I don't think I can get to it today.

I decided to rewrite my mass properties utility, clean up its unit tests and submit it to the public domain. I've attached a tarfile with the code. Alternatively you can download it from my google drive here.

The code will compute the volume, center of mass, and inertia tensor of any closed mesh.
