[Opm] Request of information

Hi,
> I am afraid the question is surprisingly complicated to answer.

In as sense you are right, however there is very nice paper :
http://www.osti.gov/scitech/servlets/purl/632793/

that puts it into relatively simple equation after doing some
reductions that minimize the number of floating point operations.
The whole problem boils down to calculation of three 3x3 determinants
and couple of vector subtractions.

This is not directly related to OPM but might by interesting to OPM users
as well.

Regards,

Roman
