Your m_Sphere mesh is not properly closed; while POV-Ray will still 
/try/ to treat such meshes as solids if you use the "inside_vector" 
keyword, this actually only works in very few cases, and you will 
usually get artifacts when using such a mesh in CSG.

In an intersection with a single other object, for instance, the effect 
is that any gaps in the mesh will be projected along the inside_vector, 
causing the surface of the other intersected object to be visible within 
the region of this projection.

The only reliable way to avoid such artifacts is to properly close all 
meshes you use in CSG.
