Use an instance of this dragger class in your scenegraph to let the end-users of your application rotate geometry around a pre-defined axis vector in 3D.
The special feature of this dragger that sets it apart from the other draggers that provides rotation around an axis (like the SoRotateCylindricalDragger) is that it provides a convenient interface to rotate around an axis that is pointing in approximately the same direction as the camera. This is useful for interacting with for instance something like a "volume" knob.
For the dragger orientation and positioning itself, use some kind of transformation node in your scenegraph, as usual.
|
Default constructor, sets up the dragger nodekit catalog with the interaction and feedback geometry. |
|
Protected destructor. (Dragger classes are derived from SoBase, so they are reference counted and automatically destroyed when their reference count goes to 0.) |
|
Initializes type system for this dragger class. Application programmers should usually not have to invoke this method, see documentation of SoInteraction::initClass(). Reimplemented from SoDragger. |
|
Sets up all internal connections for instances of this class. (This method will usually not be of interest to the application programmer, unless you want to extend the library with new custom nodekits or dragger classes. If so, see the SoBaseKit class documentation.) Reimplemented from SoInteractionKit. |

This field is continuously updated to contain the rotation of the current direction vector of the dragger. The application programmer using this dragger in his scenegraph should connect the relevant node fields in the scene to this field to make them follow the dragger orientation. |
