Detailed Description

Keeps track of Inventor draggers attached to worldElements or DOF's.

A dragger is an Inventor object which allows the user to use the mouse to move worldElements or DOF's. Each time a dragger is created, a new instance of this structure is create to keep track of the dragger and information related to it. There are 4 types of draggers currently used:

For moving the base of a robot, an object or an obstacle:
- A handlebox allows 3D translation of the element
- A centerball allows 3D rotation of the element about an arbitrary point
For moving a DOF:
- An arrow allows translation of prismatic DOF's
- A disc allows rotation of revolute DOF's
