Detailed Description

The SoAngle1Dragger class is for rotating geometry around a single axis.

/ SoAngle1Dragger.h

Use an instance of this dragger class in your scenegraph to let the end-users of your application rotate geometry around a pre-defined axis vector in 3D.

For the dragger orientation and positioning itself, use some kind of transformation node in your scenegraph, as usual.

This class offers a field angle, given in radians. This field holds the current angle, in un-normalized values. In other words, it holds the number of rotations the dragger has done.

Constructor & Destructor Documentation

◆ SoAngle1Dragger()

SoAngle1Dragger::SoAngle1Dragger ( void )

Default constructor, sets up the dragger nodekit catalog with the interaction geometry.

◆ ~SoAngle1Dragger()

SoAngle1Dragger::~SoAngle1Dragger ( )

protected

Protected destructor.

(Dragger classes are derived from SoBase, so they are reference counted and automatically destroyed when their reference count goes to 0.)

Member Data Documentation

◆ angle

SoSFRotation SoAngle1Dragger::angle

This field is continuously updated to contain the angle (in radians) of the current direction vector of the dragger.

The application programmer using this dragger in his scenegraph should connect the relevant node fields in the scene to this field to make them follow the dragger orientation.

The angle hold un-normalized values. In other words, it holds the number of rotations the dragger has done, in addition to the orientation.
