Why would you want one?
 Always looking for ways to create a
 picture or a part.
 - Software.
 - 3D scanner.

 With 3D data, we can then proceed to
 ……….
 What Application Are
  You Looking For
Inspection
Industrial design
Rapid prototyping
Reverse engineering
Medical, surgical planning and plastic
surgery
Computer graphics.
Engineering Application
What can be scanned.
Most everyday objects from a coin to a
mock up of a car.
Scanning is best for free form or organic
objects.
  WHAT CANNOT BE
    SCANNED?
Transparent.
Complicated. E.g. Coral, spring, curly
hair.
Dark colors. E.g. black, dark brown.
Shiny surfaces.
          The Solution
  Spray the object with a coat of white
  powder.
- Non destructive.
- Can be cleaned away after scanning.

A glassware
manufacturer wishes to
reduce the time it takes
to produce a metal
mould with such
intricate design. With
scanning an artist can
now carve the design on
plaster, scan and have a
IGES surface to
machine the mould out.     IGES Surface    Machine Part

                          Using the PET software the
                          data can be export in ASCII
                          format to be taken in by a
                          CAD software like Surfacer
                          and a surface can then be
                          created from the point cloud
                          data.

Reverse engineering, using a CMM to
obtain the profile of this car panel would
take 8 to 10 hours depending on the CMM
machine and accuracy. This example was
scan with the VIVID 900 in an hour, the
scanned data was then edited to get a good
polygon model. NURBS surfaces can be
created to be exported into CAD software.
                       Inspection



Scanned data and CAD data.    Use the center of the holes as reference




Align the 2 sets of data.
        Computer Graphics

Model
    The creation of a CG character is one of the most challenging task
    an animator has to work on. Using 3D scanning technology the
    features of a human model can be captured easily and exported
    into an animation software like Maya. NURBS surfaces are
    created and bones are added into the model. Once done the
    animation process can begin.
Medical Applications.




          Tradition tools of medical diagnosis presents
          information in 2D, for e.g x-rays. However,
          we are living in a 3D world, people are 3D.
          The improvement of technology has allowed
          the merging of surface scan and other 3D
          imaging data. The result is better
          understanding and treatment of the patient.
            Advantages
Faster than conventional CMM.
CMM are accurate to a finite number of probed
positions. Do not get the whole surface data.
Gives complete surface data rather than cross
sections.
Easy to set up and use.
Scan objects of different sizes.
Scanning of soft objects is possible, like foam seats
and clay models.
Can be used to scan interior & exterior of vehicle
shapes.
Can inspect a surface area as compared to just
sample points.
