 |
 |   Description:
 |	This file defines the rotational disc dragger class.
 |	This is a simple dragger that returns a rotation
 |	based on vectors from the center of the disc to the intersection
 |	with the mouse.
 |
 |	The mouse position is projected onto a plane determined
 |	by the center and the normal.
 |
 | NOTE TO DEVELOPERS:
 |     For info about the structure of SoRotateDiscDragger:
 |     [1] compile: /usr/share/src/Inventor/samples/ivNodeKitStructure
 |     [2] type:    ivNodeKitStructure SoRotateDiscDragger.
 |     [3] The program prints a diagram of the scene graph and a table with 
 |         information about each part.
 |
 |  The following parts in this dragger are created at construction time.
 |  'ResourceName' corresponds to the name of the default geometry for the
 |  part. The dragger's constructor gets the scene graph for 'ResourceName'
 |  by querying the global dictionary ( SoDB::getByName("ResourceName"); ).  
 |
 |  Resource Name:                           Part Name:
 |
 |  rotateDiscRotator                      - rotator
 |  rotateDiscRotatorActive                - rotatorActive
 |  rotateDiscFeedback                     - feedback
 |  rotateDiscFeedbackActive               - feedbackActive
