| $Revision: 1.1.1.1 $
|
| Description:
| This file defines the Rotate Cylindrical dragger class.
| This is a simple dragger that returns a rotation
| based on vectors from the axis of the cylinder to its surface.
|
| The mouse position is projected onto a cylinder determined
| by the axis and the radius. The radius is determined by the
| distance from the axis to the initial hit point.
|
| NOTE TO DEVELOPERS:
| For info about the structure of SoRotateCylindricalDragger:
| [1] compile: /usr/share/src/Inventor/samples/ivNodeKitStructure
| [2] type: ivNodeKitStructure SoRotateCylindricalDragger.
| [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:
|
| rotateCylindricalRotator - rotator
| rotateCylindricalRotatorActive - rotatorActive
| rotateCylindricalFeedback - feedback
| rotateCylindricalFeedbackActive - feedbackActive
|
