MANUAL SHAPE DEFINITION AND OPTIMIZATION |
| Traditional working
materials are clay and hardened foam. There is a
direct sensory
connection between stylist and model. Hand and eye perceive realistic
facts. Many stylists would rather work manually only. Difficulties
start when holding a physical model in hand does not suffice anymore
but reliable data concerning the shape are necessary to make the
model reproducible. For
simple parts, this can be done by traditional measuring and afterwards recreation within the CAD system.
With more complex free-form parts
like a car body, the model is usually scanned with the help of very
exact measuring methods (such as
laser triangulation and stereo photo-grammetry), and
it is then processed with a special software for semi-automatic surface
reconstruction so that acceptable CAD surfaces are available
in the end.
