3. Disclaimer
1.This presentation is about the experiences I have made
with 3D scanning in the past 6 month.
2.It is meant as an entry point and a kickstart for persons
who want to start 3D scanning without big costs.
3.It doesn't cover the technical details but focusses on the
practical aspects.
4.To get a more in-depth view on the different methods
and techniques, see for instance:

6. Why would you want to 3D-scan an
object?
● As soon as you have a 3D printer, one of your new
hobbies will consist in collecting (and printing, of
course!) 3D models.
● You can draw the models yourself (any CAD),
program them (e.g. OpenSCAD), download them
(e.g. thingiverse.com) and so on...
● But sometimes, you would simply like to have a
copy of that physical object in front of you.
7. How I got into 3D printing...
● I was playing around with some tools, but nothing
seriously. And dropped the subject.
● A client called to have a toy figure printed out.
● But: He did not really have the 3D model. He
wanted to be the model itself...

based on existing frameworks like e.g.
OpenKinect or OpenFramework.

19. The 3D scanning workflow is pretty
straightforward.
● Get the model you want to scan.
● Obvious.
● Scan it.
● See two possible ways in a few seconds...
● Clean it up (might take several iterations).
● Might take quite some time, depending on how you created
the model.
● Use it.
● :-)

23. Many tools can be used to clean-up the
models and further process them...
● MeshLab: Viewing and editing many 3D file formats.
● MeshMixer: Creating 3D Mash-ups
● NetFabb: Cleaning 3D Models
