Introductory Hypothesis

Your personal understanding of 3D scanning is based on the perspective of what you have seen,

and it is difficult to extend that perspective without more knowledge and experience.

“The years teach much which the days never know.”

Ralph Waldo Emerson


Review: Geomagic Convergence 2007

Factors that effect choice of
