Most have you have probably seen this project and I'm sure its not done in GH but i want to know if anyone has an idea on how to go about what is seen from 40-50 seconds, the way they make the land form based on the curves. Some way to "pipe" curves yet they are smoothed together in proximity of one another. https://www.youtube.com/watch?v=9VsUbInC-Uw.
