18 Creating and Managing Trackers
Q3Tracker_GetNotifyThresholds
function to get the current notify thresholds of a tracker.
TQ3Status Q3Tracker_GetNotifyThresholds ( TQ3TrackerObject trackerObject, float *positionThresh, float *orientationThresh);trackerObject
A tracker object.positionThresh
On exit, the current position threshold of the specified tracker.orientationThresh
On exit, the current orientation threshold (in radians) of the specified tracker.
Q3Tracker_GetNotifyThresholds
function returns, in the positionThresh
and orientationThresh
parameters, the current position and orientation thresholds of the tracker specified by the trackerObject
parameter. These thresholds determine whether or not a change in position or orientation is large enough to cause QuickDraw3D to call the tracker's notify function. Both thresholds for a new tracker are set to 0.
