My Fun Projects: FLARManager

In the previous blogs, details about the Software installation, marker creation, 3D Model and links to resources were posted.

Now to understand how this works please review:

The following is the Code (Not final version - Needs tuning for performance and some changes to include the overall scope of the project ) for the Interactive Strory Telling Project - Myths from Amazon.

(Thanks to the developers that support open source and posted sample code at various sites.
The sample code from: http://gotoandlearn.com/ was used as the basis for this project)
