CSG with meshes (even open meshes) should work as long as the mesh is well
behaved:
-mesh is continuous withing the CSG region
-mesh normals are properly defined and oriented
-inside vector included
This helps POV to determine what is in or out. In the bathtub pic I posted
recently, the water is actually an intersection of an open mesh and a
heightfield and it worked no problem once I made the mesh well-behaved.
For meshes that are non-well-behaved, they may or may not work as expected.
