Well, Bathsheba is surely into some real good stuff.

On a similar note, today we released Point Cloud for Rhino
( This Rhino plug-in will read an
unorganized point cloud and convert it into an organised surface, for
reverse engineering purposes. Comments, suggestions, criticizm are most

This plug-in was developed on the request of Dr. Schmitt (who is on this
list). Thought I should let you people know.
