How to compute the merged volume of two 3D objects [message #59665]

Dear all,

If I want to compute the merged volume of two 3D objects, for instance
a overlapped sphere and cube, I first use MESH_MERGE to merge the
polygonal meshes of the two objects and then use MESH_VOLUME to get
the merged volume.

The problem is that I found the MESH_MERGE, if I am right, just
simply put together the vertices and connectivity of the two objects
and did not do any real mergence of the overlapped vertices.
Therefore, the volume I got after applied MESH_MERGE, still equel to
Volume1 + Volume2 and not the merged volume.

Is there any good idea how to compute the merged volume, or I have to
"manually" get rid of the overlapped vertices and rewrite the
connectivity array...?

Any idea or suggestion would be greatly appreciated.

Cheers,
yingjie
