SoCenterballDragger is a composite dragger. Its shape is a sphere defined by three intersecting circles. Where the circles intersect (at the ends of the x, y and z axes) there are sets of small green crosshairs. Dragging a pair of crosshairs translates the entire centerball within the plane of the crosshairs.
The interface of the sphere and circles is just like SoTrackballDragger. Dragging a circle rotates about a constrained axis and dragging the areas between them rotates the sphere freely about the center. An invisible but pickable sphere initiates the free-rotation dragging.
When you drag the crosshairs, the center field is updated; there is no translation field. Dragging other parts of the centerball updates the rotation field. As with all draggers, if you change the fields the dragger moves in response.
The draggers used for the crosshair parts are SoTranslate2Draggers, so pressing the <Shift> key allows you to constrain motion to slide along either the local x axis or y axis of that crosshair.. The direction is determined by your initial mouse gesture after pressing the key. Releasing the key removes the constraint.
Remember: This is not an SoTransform! If you want to move other objects with this dragger, you can either:
[a] Use an SoCenterballManip, which is subclassed from SoTransform. The manipulator creates one of these draggers and uses it as the interface to edit the manipulator's fields. (See the SoCenterballManip man page.)
[b] Use field-to-field connections to connect the fields of this dragger to those of any SoTransformation node.
You can change the parts in any instance of this dragger using setPart(). The default part geometries are defined as resources for this SoCenterballDragger class. They are detailed in the Dragger Resources section of the online reference page for this class. You can make your program use different default resources for the parts by copying the file /usr/share/data/draggerDefaults/centerballDragger.iv into your own directory, editing the file, and then setting the environment variable SO_DRAGGER_DIR to be a path to that directory.
