Besides our own software, we use the Surfacer package from Imageware for
such purposes.
It has the ability to do a cloud-to-surface difference plot, so you can
see the difference between points and a 3D surface CAD model. The second
possibility are slices, just as you mentioned.
Imageware has some pr pages at, or you send e-mail to for detailed questions.

Hope this helps.

With kind regards, Juergen Bauer

P.S.: I am NOT paid by Imageware - dont flame me for this !
