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 motion. 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. ## FIELDS **SoSFRotation** **rotation**\ Orientation of the dragger. ## METHODS **SoRotateSphericalDragger()**\ Constructor. **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 **SbSpherePlaneProjector**. 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. ## CATALOG PARTS | | | | | | --- | --- | --- | --- | | **All parts** | | | | | **NULL by** | | **Part Name** | **Part Type** | **Default Type** | **Default** | | | | callbackList | NodeKitListPart | -- | yes | | rotator | Separator | -- | yes | | rotatorActive | Separator | -- | yes | | feedback | Separator | -- | yes | | feedbackActive | Separator | -- | yes | | | | | | | | --- | --- | --- | | **Extra information for list parts from above table** | | **Part Name** | **Container Type** | **Permissible Types** | | | | callbackList | Separator | Callback, EventCallback | | | ## DRAGGER RESOURCES .in 0n+.5i Resource: **rotateSphericalRotator**\ .in 0n+.5i Part: rotator\ Appearance: white sphere made of three intersecting circles.
