To which version of PoV-Ray do you refer? When I played around with very 
small objects some years ago (must have been version 3.1), I found out 
that everything smaller than about 1/12,000 unit was not rendered 
anymore... so I wonder that nowdays epsilon should have been lowered 
down to 1e-10, which is a cool six orders of magnitude smaller!

See you in Khyberspace!
