Cubic spline planning: Spline2D doesn't generate spline from closely spaced x-y waypoints about pythonrobotics HOT 3 CLOSED

@babylonman Thank you for sending your code.
There is a solution about your problem.
You should make the third input of np.arange smaller, because this input means the sampling distance of the interpolated path.
Your x-y points are sampled in a very narrow area, this means you have to choose smaller value for it.

Like:
s = np.arange(0, sp.s[-1], 0.001)

If I set the value, I can get this result with your code. It seems good.

Hi @babylonman . Thank you for your interest.
Can you post your actual code here?.
I will test it.

@AtsushiSakai , I've attached an example based on the original test you included in cubic_spline_planner.py.

Thanks for the great collection of resources by the way!
