Geometric Methods for Reverse Engineering
In many areas of industry, it is desirable to be able to
create geometric models of existing objects for which no such
model is available. Such ability is useful in a wide range of
applications including manufacturing replacements for obsolete
parts, making variations of former designs, capture of
hand-crafted models, and construction of medical prostheses. By
creating a geometric model the powerful tools of current CAD/CAM
packages become available allowing, for example, editing,
analysis, visualization and NC manufacturing. The speakers in
this minisymposium will discuss constructing a geometric model
assuming some measured input data is already available.
