从曲线形状中获取均匀分布的点

如何采用在曲线上有更多点创建的形状并将其细分，以使点沿曲线分布更均匀？在我的研究中我认为numpy's interp https://numpy.org/doc/stable/reference/generated/numpy.interp.html可能是正确使用的函数，但我不知道参数使用什么（x, xp, fp, left, right, & period）。任何帮助将不胜感激！

这是显示所需输出的动画。

这是输入圆角矩形的代码：

from matplotlib import pyplot as plt
import numpy as np

x_values = [1321.4, 598.6, 580.6, 563.8, 548.6, 535.4, 524.5, 516.2, 511,
509.2, 509.2, 511, 516.2, 524.5, 535.4, 548.6, 563.8, 580.6, 598.6, 1321.4, 1339.4,
1356.2, 1371.4, 1384.6, 1395.5, 1403.8, 1409, 1410.8, 1410.8, 1409, 1403.8, 1395.5,
1384.6, 1371.4, 1356.2, 1339.4, 1321.4]
y_values = [805.4, 805.4, 803.5, 798.3, 790.1,
779.2, 766, 750.8, 734, 716, 364, 346, 329.2, 314, 300.8, 289.9, 281.7, 276.5, 274.6,
274.6, 276.5, 281.7, 289.9, 300.8, 314, 329.2, 346, 364, 716, 734, 750.8, 766, 779.2,
790.1, 798.3, 803.5, 805.4]

fig, ax = plt.subplots(1)
ax.plot(x_values,y_values)
ax.scatter(x_values,y_values)
ax.set_aspect('equal')
plt.show()

谢谢你！
