This example gets the Pan, Tilt and Field of View ranges for a QuickTime VR object called qtvr
var Pan_Range = qtvr.GetViewingLimits(0);
Debug.trace( "Pan: fMin = " + Pan_Range.fMin + " fMax = " + Pan_Range.fMax + "\n")
var Tilt_Range = qtvr.GetViewingLimits(1);
Debug.trace( "Tilt: fMin = " + Tilt_Range.fMin + " fMax = " + Tilt_Range.fMax + "\n")
var FoV_Range = qtvr.GetViewingLimits(2);
Debug.trace( "FoV: fMin = " + FoV_Range.fMin + " fMax = " + FoV_Range.fMax + "\n")
