## DESCRIPTION

**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 **/usr/share/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.
