Subject: Re: *MOPER with beta MAP function...

Presumably when you say "The procedure looks for each point in all possible
triangles (tetrahedrons)", the search is limited to only those which are
currently selected? If not, this might be a simple way of speeding things
up.

Certainly your suggestion of three possible outcomes for an out-of-bounds
point are all useful: a good overcheck to make sure that the map is
oriented correctly with the model (and of similar size & shape) would be
first to map on setting out-of-bounds points to zero.
