Houdini - Custom POP Velocity with VDB (scene file)
So today I fell back into playing with custom velocity fields and created this vortex/path following thingie. I'm procedurally creating a point cloud with the calculated velocities from an input path, then I'm converting it to VDB and use volume sampling in the POP's to drive particle velocity. :)
