Just found out that the two methods yield different results. This caused a lot of confusion for me, so I wanted to share it.
ofEasyCam cam; cam.getOrientationEulerDeg(); // returns angles from [-90, 90] with a "change in direction" when reaching the limits cam.getOrientationQuat.getEuler(); // returns angles from [-180, 180] with a "jump" between the limits
I was expecting
cam.getOrientationEulerDeg() to yield the same results as
cam.getOrientationQuat.getEuler(), so it took me some time to find out that it doesn’t. Hope this can help someone.
