Functions determining transformation paths between sets of points.
path_along_arc(arc_angle, axis=array([0.0, 0.0, 1.0]))¶
If vect is vector from start to end, [vect[:,1], -vect[:,0]] is perpendicular to vect in the left direction.
straight_path(start_points, end_points, alpha)¶
Same function as interpolate, but renamed to reflect intent of being used to determine how a set of points move to another set. For instance, it should be a specific case of path_along_arc
