[osg-users] About the parameter _lock_azim_while_panning in OSGEarth EarthManipulator

[Glenn Waldron]

Mingxia,

That is by design - if you lock your camera azimuth (to north-up for
example), you will be unable to rotate past the poles. You can disable the
feature by calling
EarthManipulator::getSettings()->setLockAzimuthWhilePanning(false).

Hope this helps
