perhaps it is me who misunderstands.  you are talking export POV -> yourFormat ?
 (I had thought the other way round)

re 'trace', yes, you can use the optional parameter to check the normal's not
zero and take whatever "action" is needed.

re duplicate vertices, it might be easier to revise the generating scene such
that duplicates cannot occur rather than trying to "weed them out".

it would be helpful to see a pared-down scene, perhaps part of the generated
data.
