abstract = "3D shape design tends to be a long and tedious process, with the
design of a detailed 3D part usually requiring multiple revisions.
Fabricating physical prototypes using low cost 3D fabrication
technologies at intermediate stages of the design process is now a
common practice, which helps the designer discover errors, and to
incrementally refine the design. Most often, implementing the
required changes directly in the computer model, within the 3D
modeling software, is more difficult and time consuming than
modifying the physical model directly using hand cutting, caving
and sculpting tools, power tools, or machine tools. When one of
the two models is modified, the changes need to be transferred to
the other model, a process we refer to as synchronization. Changes
made to the computer model can be transferred to the physical
model by 3d printing a new physical model. In this paper, we
address the problem of synchronizing the computer model to changes
made in the physical model by 3D scanning the modified physical
model, automatically detecting the changes, and updating the
computer model. The proposed process comprises algorithms to: 1)
register each 3D scan with a previous 3D scan and/or with the 3D
representation used by the 3D modeling software; 2) detect the
changes (subtractive and/or additive); and 3) perform the changes
on the 3D computer model.",
