Adding a Voronoi tool to TIGER, my Rhino plug-in — it generates a 3D Voronoi lattice inside any closed solid, with a live preview so you can dial it in before you commit.
What it does
- Seeds n points inside a closed solid and builds the Voronoi cell network from them — the point count and a density bias are both sliders, so the lattice re-solves as you drag.
- Pipe Preview pipes the struts live at any radius, so you see the actual buildable geometry, not a wireframe approximation.
- Trim lattice at the surface clips the network to the host solid, with optional boundary curves where it meets the skin.
- Surface Voronoi mode keeps the pattern on the surface only, if you want a shell rather than a fill.
- Pick your own seed points instead of random ones when you need control over the density.
- Bake what you need: cell solids, centerpoints, or just lines. Optional boolean union of the struts.
Baking as cell solids gives you individually editable closed volumes — useful for packing studies, or for pulling a cell out to work on it on its own.
The run in the clip is 40 seeds → 309 struts → 314 boundary curves, solving fast enough to keep scrubbing the sliders.

Curious what people would want out of this — grading density toward a stress field, non-uniform strut radii, mesh output for printing? Feedback welcome.
