Source 
pub fn rotate(dir: &Vector3d, pole: &Vector3d, angle: Angle) -> Vector3d
Expand description

Calculate the direction vector of a Great Circle rotated by angle.

  • dir - the direction vector of a Great Circle arc.
  • pole - the pole of a Great Circle.
  • angle - the angle to rotate the direction vector by.

returns the direction vector at the point on the great circle rotated by angle.
