orbiting navigation added #70

Open brezhnyev opened 1 year ago

brezhnyev commented 1 year ago

the camera remains parallel to XY plane (no rolling). Tested with QT5 on Ubuntu18.04 and Ubuntu20.04. Added ORBIT into the keyboardAndMouse example.

Thanks for this contribution.

I can imagine the use case of such a motion. However, it seems specific since the XY plane is arbitrary. I wonder if the same result cannot be achieved using a Constraint applied to the camera frame. See details in the associated example.

Hi, Understand. Alternative would be to introduce not just one, but three such orbiting options. ORBIT_XY, ORBIT_YZ, ORBIT_ZX otherwise ORBIT_X, ORBIT_Y, ORBIT_Z

Regards.
