This is a tutorial on how to use 123D Catch to get a 3D scan of your whole body. Once you have the scan or "catch" the tutorial will take you through a technique to clean it up and manipulate it ready for 123D Make. The tutorial will go through how to slice the model in Make and prep it for Laser cutting. The tutorial will briefly cover how lazer cutting and integrating the componentry and Arduino to make the head turn. The tutorial will wrap up with some example code of what worked for me during this project.

Step 1: Preparing the Catch

Picture of Preparing the Catch
For the catch of the your body you will need someone assist you.

There are two approaches to the catch, with an iphone/ipad or with a digital camera & computer. In my experience I have found the iphone/ipad method to be the fastest & most reliable so that is the method I will explain  If you would like to know the other method (which is actually very similar) visit:http://www.123dapp.com/catch/learn

For the iphone/ipad approach download the (free) 123D Catch app from the app store 123D Catch App. Then create an account & log in.

You (person being catched) should be sitting on a simple stool with enough room around them for the "assistant" (person assisting taking the catch) to walk around them taking photos keeping the catchee's body within the frame.

The environment should be as evenly lit as possible but does not require studio quality backdrops or lights.

The catchee should sit as still as possible and stare directly forwards with eyes closed.

Yeah! Nice one.

It would be great to see a video of this thing in action.
I second the video

wow this is really awesome - nice work!
This is awesome! I saw the catches on the 123D Gallery and I'm excited to see something physical come out of them. :D
Beautiful and craftsy!

Have you thought of scaling up the size of your felt-self to offset the raw/spider-like look of the IR sensor? Were you going for that look?
Plarky (author)  T3h_Muffinator1 year ago
Yes the sensors are a bit distracting, I am tempted by a larger standing version as a future project.

That is crazy awesome! Oh man,I would love to see a full scale version.
Nice work

Full Scale version was the original plan, but thick felt is so expensive. Perhaps version 2.0 will be Full Scale.
