       SoRotateSphericalDragger  is  a  simple dragger that rotates freely in all directions. The
       feel of the rotation is as if you were rolling a ball.  The  center  of  rotation  is  the
       origin  of  the  local  space,  determined  by  the dragger's location in the scene graph.
       Transformation nodes placed before it will affect both the dragger and  the  direction  of

       This  node  has a rotation field which always reflects its orientation in local space.  If
       you set the field, the dragger will rotate accordingly. You can  also  connect  fields  of
       other nodes or engines from this one to make them follow the dragger's orientation.

       This dragger contains four parts, rotator, rotatorActive, feedback, and feedbackActive.

       Each of these is set by default from a resource described in the Dragger Resources section
       of the online reference page for this class. You can change the parts in any  instance  of
       this dragger using setPart().

       You  can  make  your  program use different default resources for the parts by copying the
       file /usr/share/data/draggerDefaults/rotateSphericalDragger.iv into  your  own  directory,
       editing the file, and then setting the environment variable SO_DRAGGER_DIR to be a path to
       that directory.

     void                       setProjector(SbSphereProjector *p)
     const SbSphereProjector *  getProjector() const
          Set and get a different sphere projector. See the SbSphereProjector man pages  to  find
          out  how  each  kind  affects  the  feel  of your dragger's motion. The default uses an

          Passing in NULL will cause the default type of projector to be used. Any projector  you
          pass  in  will  be  deleted by this dragger when this dragger is deleted. Note that the
          center and radius of the sphere are determined by the dragger, based on the  origin  of
          the local space and the distance between the initial mouse click and that origin.

     static const SoNodekitCatalog *
                                getClassNodekitCatalog() const
          Returns an SoNodekitCatalog for this class

     static SoType              getClassTypeId()
          Returns type identifier for this class.
