Generate directional vector field using guide vectors on random points

[prashant-saxena]

Hello,

1. Blue dots are randomly generated points in UV space. (0-1)
2. Red arrows represent guide vectors. (position and direction)
3. An algorithm that can generate direction on points based on guide vectors (right image)

I gave a try using the K-Nearest-Neighbor algorithm but the resulting vectors are not following guide vectors smoothly. After searching on Google I came to know about "smooth tangent vector field", and that's what I'm looking for. This paper and video is describing the solution but unfortunately, there is no source code. The documentation shows Geometry Central supports vector field generation algorithms. Is it possible to do what am I looking for using Geometry Central?
