algorithmic modeling for Rhino
In this Grasshopper Script, you can generate Voronoi cells on a Nurbs surface and also define point & Curve attractors. these attractors can control the height or scale of the openings.
Voronoi on Surface
Base Surface : A Nurbs Surface for generating voronoi cells.
Panels Count : Number of panels.
U : Number of cells in the U direction.
V : Number of cells in the V direction.
Attractors: Attractors as point(s) or Curve(s).
Min Height : The minimum height of the cells
Max Height : The maximum height of the cells
Min Scale : The minimum Scale for the Openings
Max Scale : The maximum Scale for the Openings
Voronoi : The voronoi panels.
Openings: The Opening element of the panels.
