Most people are very familiar with the process of scanning
2D images to convert them to digital data that can be manipulated
on the computer. But they are less familiar with scanning
3D objects to attain 3D digital data that can be manipulated
on the computer. The 3D area of the Studio offers an array
of 3D scanning devices that scan objects of various sizes
in various ways. You can bring in an object to be scanned,
scan yourself, or sculpt an object out of clay and scan that.
Objects are, in effect, measured or imaged three dimensionally,
and then those measurements or images are translated into
points that are placed in a virtual 3D space. On the computer,
the points become vertices that can be connected by segments
to create a "skin" or "surface" of triangles and squares that
are the digital equivalent of the surface of the object that
was scanned. Some scanning processes result in a very detailed
digital model, while others capture only the primary features
of objects. Once an object has been scanned and converted
into a digital model (usually an .stl file), that file can
be imported into 3D modeling applications to enable further
cleanup or manipulation (cut, scaled, twisted, bent, combined
with other models, etc.). Then the model can be output to
a rapid prototyping machine, animated with 3D animation software,
or shaded, textured, rendered, and printed as a 2D image.
3D Data Capture Procedures
1. Sign up for a 3D scanning session (sign ups are offered
one day in advance and on a first-come, first-served basis).
2. Pick up a work slip when you check in and bring something
to be scanned: an object, yourself, or and object that you
modeled in clay in the hands-on area of the Studio.
3. Complete the scan.
4. Scanned data will be placed in a folder on the 3D server,
where it is accessible from any of the 3D workstations. From
there, the scanned data can be manipulated and prepared for
rapid prototyping, 2D printing, or animation.
5. If you would like your object file written to CD, check
the 3D Data CD box on the work slip and follow the instructions
6. If you would like your object rapid prototyped, check the
3D Model box on the workslip and follow the 3D
Rapid Prototyping Procedures.
7. If you would like a 2D print of your work, refer to the
8) If you would like to animate your object, refer to the
