vizard rotations

[duda]

Is there a command in Vizard that allows you rotate with respect to an inertial frame? e.g. if viz.rotate(0, 10, 0) is performed, and then viz.rotate(0, 15, 0) is performed, the end result is a 25-degree pitch. However, I'd like the end result to be a 15-degree pitch.

I'd like to take head-tracker sensor data, perform some operations on it, and then use the viz.rotate command to update the view. Currently, there is an instability because rotations are performed on top of rotations.

Thanks for your help!
