project.)
Required tools
2. Take Digital Photos of
Your Head
Computer with Internet access and a
web browser.
MeshMixer software (optional), free .
You'll want a friend's help with this part. You
can use a cellphone camera or a nice DSLR—
the better the camera, the better 123D Catch
will work. Shooting in full shade works best.
3D printer and computer with printer
software (optional). If you don't have
access to a 3D printer, just send your 3D
model to a service instead, and they'll
print it and mail it to you (see step 10).
Sit still while your friend snaps 30 to 40 pho-
tos of your head, in two separate loops mov-
ing completely around you—one lower
loop, and one higher loop where the top of
your head is seen clearly. This will prevent
unwanted holes in your head where the soft-
ware is missing part of the scene. For best
results, make sure your head fills most of the
frame.
If you're going to stick out your tongue or
make a face, ask your friend to work fast so
you can hold your expression. But remember
to keep the camera still and focused when
snapping each photo because blurry images
may confuse the software and cause weird
horns on your head.
1. Register with Autodesk
123D
Go to http://123dapp.com and create a free
account. For this project, we'll use the web
app for 123D Catch. It stitches your digital
photos together into a 3D model.
Autodesk recently updated 123D Catch so
you can 3D print your head two ways: either
send your model out to be printed for you,
or download it so you can print it yourself.
