The Euler angle documentation states, "Roll, pitch, and yaw correspond to rotations around X, Y, and Z respectively.". The behaviour you have described is consistent with the documentation.

I see, so Fusion uses the "x forwards/backwards, y to the sides, z up/down" convention like used for aircraft, now things make much more sense. Was looking at things from a computer graphics / 3d game engine perspective where x is to the side, y is forwards/backwards and z is up/down, and things weren't making much sense. Maybe it could be possible to mention that this is the convention used somewhere in the readme?

The README already states, "The quaternion describes the orientation of the sensor relative to the Earth using the North-West-Up (NWU) convention.". That is, X = North, Y = West, Z = Up.

Ah, must have missed it when looking for it... Thank you for the quick replies, closing this.
