 // to the plane normal to the normal axis, and the x axis corresponding to
 // the projection of the reference axis onto the normal plane. The normal
 // plane is the tangent plane at the root point. A unit vector is
 // constructed along the local x axis and then rotated by the given
 // ccw angle to form the new point. The new point, then is a unit
 // distance from the global origin in the tangent plane.
