NAME SoXtConstrainedViewer SoXtConstrVwr "" {
base viewer class which adds camera constraints given a world up direction
}
INCLUDE Xt/viewers/SoXtConstrainedViewer.h
DESC {
This is a base class for the \cSoXtWalkViewer\. and \cSoXtFlyViewer\.
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.
}
METHOD setUpDir void setUpDirection(const SbVec3f &newUpDirection) {}
METHOD getUpDir 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.
}
