Class SoScaleUniformDragger

  • All Implemented Interfaces:

    public class SoScaleUniformDragger
    extends SoDragger
    Object you can scale uniformly in 3D by dragging with the mouse. SoScaleUniformDragger is a simple dragger that scales uniformly in all 3 dimensions when dragged with the mouse. The local space is determined by its location in the scene graph. Transformation nodes placed before it will affect both the dragger and the plane of motion.This node has a scaleFactor field which always reflects its size in local space. If you set the field, the dragger will change accordingly. You can also connect fields of other nodes or engines from this one to make them follow the dragger's motion.This dragger contains four parts, scaler , scalerActive , 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 $OIVHOME/data/draggerDefaults/scaleUniformDragger.iv into your own directory, editing the file, and then setting the environment variable SO_DRAGGER_DIR to be a path to that directory.

    See SoDragger for more information about using and customizing draggers, including code examples, using draggers in an immersive VR environment and using WYSIWYG draggers.

      Resource: scaleUniformScaler
      Part: scaler
      Appearance: 8 small white cubes at the corners of a larger 2x2x2 cube.
      Description: picking this initiates the scaling

      Resource: scaleUniformScalerActive
      Part: scalerActive
      Appearance: yellow version of scaler, but with extra yellow box connecting corners
      Description: displayed instead of scaler while in motion

      Resource: scaleUniformFeedback
      Part: feedback
      Appearance: thin purple 3-D crosshair
      Description: shows center of scale when still

      Resource: scaleUniformFeedbackActive
      Part: feedbackActive
      Appearance: thin, slightly brighter purple 3-D crosshair
      Description: shows center of scale while in motion
