Detailed Description

A DtSceneObject represents an object that can be positioned in the scene by (possibly) attaching it to another object.

The DtSceneObject is a container class that 'groups' multiple models into a single scene-object. A scene-object is an association of models that can be manipulated as a single unit. Among other features, the DtSceneObject identifies a single position and attitude within the scene for all models associated with it. As such, models are added to (and removed from) the scene object to be inserted to (and removed from) the scene itself. Once constructed the DtSceneObject can be positioned and oriented within the scene so that any models added to the object will also be positioned and oriented.
