The PathFrame class stores data a path's interpolating spline position, tangent, and normal data. A coordinate frame is defined by id (int): The ID of a path point. point (list([float,float,float])): A 3D path point. normal (list([float,float,float])): The normal to the path point. tangent (list([float,float,float])): The tangent to the path point.
id Path frame id.
normal Path frame normal.
position Path frame position.
tangent Path frame tangent.
