# Paths¶

manimlib/utils/paths.py 这个文件中主要实现了和路径有关的函数

manimlib.utils.paths.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

manimlib.utils.paths.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.

axis 为轴， arc_angle 为圆心角的圆弧路径

manimlib.utils.paths.clockwise_path()

manimlib.utils.paths.counterclockwise_path()
