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. The resulting data will be mapped on a 3d mesh for custom effects in 3D application Blender. I hope that I have explained clearly what I'm looking for. Although I haven't explored "Directional" much but looking at the images I think it can provide a solution.

Cheers Prashant

Directional is essentially built on an abstract structure of discrete tangent bundles (so a finite set of vector spaces that you can define a metric connection for). One example is the set of faces to a triangle mesh, but by all means you can derive your own tangent bundle. If you implement all basic operators, you could use the entire of Direcitonal's functionality with your space.

(Happy to discuss this further in the context of your application!)
