Sharing my implementation for Curvature and Gradient POPs (Measure POP)

POPs

Hi,

Happily sharing my attempt to advect particles based on the curvature of a geometry.
My idea was inspired by the Measure node in Houdini, which can calculate curvature, gradient, and more. In this example, I’m computing the gradient of curvature with the help of the Neighbor POP, then taking the cross product of the output and normals to generate the velocity field.

Hope it sparks new ideas for you and encourages you to explore these techniques!

Best,

Really nice sample @_mini_uv, thanks. I took the liberty of simplifying the particle solver by using a Particle POP. Also, you can average the direction directly with the Neighbor POP to get a velocity direction for the particles.
