Hi Jean-Pierre,
You base this tutorial on String SDK that has now been discontinued by String. Do you know any alternative solution that could replace that?
Thanks.
Hi, there are several other SDKs out there. You should have a look at
- http://www.wikitude.com
- http://artoolkit.org
- https://developer.vuforia.com
All can be used for free for testing purposes and ARToolKit is Open-Source.
This tutorial is more than six months old so questions are no longer supported at the moment for it. We will update it as soon as possible. Thank you! :]
