Member Enumeration Documentation

enum osgGA::NodeTrackerManipulator::RotationMode

Enumerator:

TRACKBALL	Use a trackball style manipulation of the view direction w.r.t the tracked orientation.
ELEVATION_AZIM	Allow the elevation and azimuth angles to be adjust w.r.t the tracked orientation.

enum osgGA::NodeTrackerManipulator::TrackerMode

Enumerator:

NODE_CENTER	Track the center of the node's bounding sphere, but not rotations of the node. For databases which have a CoordinateSystemNode, the orientation is kept relative the coordinate frame if the center of the node.
NODE_CENTER_AND_AZIM	Track the center of the node's bounding sphere, and the azimuth rotation (about the z axis of the current coordinate frame). For databases which have a CoordinateSystemNode, the orientation is kept relative the coordinate frame if the center of the node.
NODE_CENTER_AND_ROTATION	Tack the center of the node's bounding sphere, and the all rotations of the node.
