Voronoi on Surface

Traces the borders between the Voronoi cells of seed points on a mesh surface — each border runs where two seeds are equally near — as a lattice that keeps its cells. At Thickness 0 the borders are beams with no thickness yet, drawn as lines, for ribs.

Inputs

Seed points List of Point

The seed points; each one gets its own Voronoi cell (at least two).

Takes: any block that gives Point (13 blocks)
Mesh Mesh

The surface mesh the borders are traced on.

Takes: any block that gives Mesh (14 blocks)
Thickness Number

Beam diameter in mm: a number, or a field read once per beam at its midpoint.

Takes: any block that gives Number (102 blocks)

Output

Lattice

Used by: any block that takes Lattice (98 blocks)

Properties

Values the block gives besides its output. The editor lists them under Properties, and an input can read one by reference.
