Member Typedef Documentation


Member Enumeration Documentation

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.

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.
