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.
Place your vase* on a wooden table top, the reason is that 123D Catch needs reference points to create the 3D model and the grain of wood works well, newspaper can also work. The lighting should be as evenly lit as possible and you should have enough room to move around the vases taking pictures.
*If the vase you want to catch is glass or metallic try covering it in masking tape for a better result.
