Turbulent lane curves when mapping 3D lanes onto pointclouds. #23

Description

Hi! Thank you for your great work. I am trying to map your 3D points onto the corresponding pointclouds of waymo dataset. I noticed a problem:

Certain lanes seem to have very turbulent curves, especially curbs as shown in purple.

I have checked the raw data and the z values do seem to be not smooth from point to point. I am not sure if any post-processing is required, or certain types of lane are not smooth by nature.
