rotate90Around Method

Rotate this vector 90 degrees around an axis vector.

• Note that simple cross is in the plane perpendicular to axis -- it loses the part of "this" that is along the axis. The unit and scale is supposed to fix that. This matches with Rodrigues' rotation formula because cos(theta) = 0 and sin(theta) = 1

rotate90Around(axis: Vector3d, result?: Vector3d): undefined | Vector3d

@returns the (new or optionally reused result) rotated vector, or undefined if the axis vector cannot be normalized.

Returns - undefined | Vector3d
