Hi, Using a nodeTrackerManipulator to make some tests, I think I get some bug in precision...
I set the tracked node with a PAT. Each frame, this PAT is modified with two Quat and one translation. Each Quat one is a different rotation... they are added (Q = q1 * q2) and applied to the PAT. The nodeTracker seems to have a precision problem... the camera do not stay motionless relative to the PAT... a little relative translation is visible, when running more than 10s. So, Is the Quat accumulation responsible of that ? is there really a lack of precision in the manipulator ? Sorry I have no enough time to make a example to show that... but I think you can try easily. Thanks. Regards, Vincent.
