A project must extends the CGSGScene class.

Each class in the cgSceneGraph has a name begining with "CGSG".

The CGSGScene is not the scenegraph itself, but an layer over the sceneGraph. So your main class, as it extends the CGSGScene:

• provides several methods to manage mouse or touch events, selection and resize detection, ...

The CGSGSceneGraph class encapsulate :

• the root node of the graph,
• several methods to animate the transformations and attributes
