objects on a flat colored surface, like a white tablecloth. You will get bet-
ter results by using a background with patterns (

the 123D Catch software clearly differentiate between the object you are
attempting to capture and the surface it is resting on.

What kind of camera?
Point and shoot cameras, like those in a regular digital camera, phone
camera or an iPad, have been reported to take the best captures. We

resolution quality of your model when you upload your captures. 3 meg-
apixels or higher will work well. High resolution photos are not needed
and will be compressed down to three megapixels by the cloud server.

Taking Photos with 123D Catch
Your first step after planning your out your project is to methodically take
pictures of the object you want to Catch.
Provide enough information
You will need to provide enough information with your pictures for the
reconstruction software to create a model. Rotate around your object,
capturing a frame every 5-10 degrees (
Figure 9-6
). The goal is to get least
50% overlap between images. Move the camera at regular intervals and
a predictable pattern (from left to right and from top to bottom). Make
