Confusion about camera rotation documentation #638
Description
The procedural data provider doc states:
Internally, MapillaryJS operates in a local topocentric East, North, Up (ENU) reference frame.
[...]
In our procedural provider we want all cameras to look to north, so we use the [Math.PI / 2, 0, 0] angle-axis rotation for the camera reference to world reference frame transform.
As I understand angle-axis rotations, [Math.PI / 2, 0, 0] corresponds to a rotation by π/2 around the X-axis, which is the East-axis in ENU, whereas a rotation to North would be [0, 0, -Math.PI / 2]. Could you elaborate on how the rotation is defined here?
