It would be beter to use the whole original .OBJ converted into a mesh.
You wrote a programm to remove the back, what a waste of your time :-(
Maybe you can alter it to replace the back with a flat face rather than just 
removing part of the object.

Only "fix" that I can think of is not removing the back, or replacing with some 
flat face. That can't be done by POV-Ray, as your choped object is missing some 
parts.
