| $Revision: 1.1.1.1 $
|
| Description:
| This file defines the jack dragger class, so named because
| with the default geometry, it looks like the children's toy.
| This dragger allows you to perform rotations,uniform scales
| and translations, all in one spiffy gadget.
|
| Translation is done with a dragPointDragger, rotation with a
| rotateSphericalDragger, and scaling with a scaleUniformDragger.
|
| NOTE TO DEVELOPERS:
| For info about the structure of SoJackDragger:
| [1] compile: /usr/share/src/Inventor/samples/ivNodeKitStructure
| [2] type: ivNodeKitStructure SoJackDragger.
| [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:
|
| jackScalerScaler - scaler.scaler
| jackScalerScalerActive - scaler.scalerActive
| jackScalerFeedback - scaler.feedback
| jackScalerFeedbackActive - scaler.feedbackActive
