The feel of the rotation is as if you were spinning a record on a turntable or rotating the volume knob of a radio. The local space is determined by its 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 rotation. 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/rotateDiscDragger.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 **SoRotateDiscDragger()**\ Constructor. **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: **rotateDiscRotator**\ .in 0n+.5i Part: rotator\ Appearance: white cylinder (with axis along z-direction) made of lines\ Description: picking this initiates rotation .in 0n+.5i Resource: **rotateDiscRotatorActive**\ .in 0n+.5i Part: rotatorActive\ Appearance: yellow version of rotator, with added yellow cube\ Description: displayed while in motion instead of the rotator .in 0n+.5i Resource: **rotateDiscFeedback**\ .in 0n+.5i Part: feedback\ Appearance: thin purple line along local z-axis\ Description: shows center of rotation when not moving .in 0n+.5i Resource: **rotateDiscFeedbackActive**\ .in 0n+.5i Part: feedbackActive\ Appearance: thin, slightly brighter purple line along local z-axis\ Description: shows center of rotation when moving ## FILE FORMAT/DEFAULTS ``` RotateDiscDragger { renderCaching AUTO boundingBoxCaching AUTO renderCulling AUTO pickCulling AUTO isActive FALSE rotation 0 0 1 0 callbackList NULL rotator rotatorActive feedback feedbackActive } ``` ## SEE ALSO **SoInteractionKit, SoDragger, SoCenterballDragger, SoDirectionalLightDragger, SoDragPointDragger, SoHandleBoxDragger, SoJackDragger, SoPointLightDragger, SoRotateCylindricalDragger, SoRotateSphericalDragger,** **SoScale1Dragger, SoScale2Dragger, SoScale2UniformDragger, SoScaleUniformDragger, SoSpotLightDragger, SoTabBoxDragger, SoTabPlaneDragger, SoTrackballDragger, SoTransformBoxDragger, SoTransformerDragger,** **SoTranslate1Dragger, SoTranslate2Dragger**
