I should clarify: Not ideal because sometimes it's the very fact that the
user can see inside the structures inside the rock that makes it possible
for him/her to piece the parts together. If the contact areas between the
two pieces is very regular and offers little guidance on how they fit
together, the density variations in the rock may be the best or even the
only guidance.
