DESCRIPTION
This is a base class for the SoXtWalkViewer and SoXtFlyViewer component viewers. This class adds methods and convenience routines available to subclasses to constrain the camera given a world up direction. This prevents the camera from looking upside down. By default the +Y direction is used.

METHODS
void
setUpDirection(const SbVec3f &newUpDirection)
SbVec3f
getUpDirection()
Specifies the upward direction of the viewer. This up direction is used by the viewers to constrain the camera when tilting up/down, and also used when rotating the camera right/left. The default is the +Y (0,1,0) direction.
