I was wondering what the best method for brining in a surface that we will
have laser scanned (imagine a coke can shape with a rock candy like outer
surface). I will then want to use this scan to cut in half to create a mold
pocket to make that shape.
You mean like a crystal facet type surface ? A bunch of polygon flats ?
I don't know how you'd do this even with a specialized program like
Geomagic. You don't really want to drape a surface over the points. It'll
just smooth out all the details. You almost need exact vertex points and
some way of connecting the dots.
A point cloud is a point cloud. No more; no less. It's all in the

I had the privilege of a 3-hour one-on-one demo of this product.
Geomagic's products are interesting. Not only can it make surfaces
from point clouds, it can also recognize where surfaces should break
off into fillets, holes, etc.
I have had mixed luck with the hacks implementing the software,
though. I had a die laser scanned and processed. I received a
single-surface model like a towel dropped across the piece, and the
service firm insisted that was all they could give us. I know the
GeoMagic software can do more, like recognize cylndrical and planar
faces and process them accordingly, so I was really disappointed.
Moral of the story: talk to the software vendor so you know what is
possible. Some service firms are either too stupid or too lazy to
