Tet Tools Panel
Tetrahedral meshing and lattice topology generation for creating generative structures from closed meshes.
Tetrahedralize
Tetrahedralize a closed mesh. Click Run to process.
| Input | Nickname | Description | Default |
|---|---|---|---|
| Mesh | M | Closed mesh to tetrahedralize | — |
| Min Ratio | R | Minimum radius-edge ratio (≥ 1.0) | 1.5 |

| Centroids | C | Tet centroids |
| Inner Edges | IE | Interior tet edges (deduplicated) |
| Surface Edges | SE | Boundary tet edges on the surface |
| Surface Mesh | SM | Outer surface mesh |
| Info | I | Statistics including radius-edge ratio |
Lattice Components
All lattice components consume Points + TetraIndices from Tetrahedralize and produce Struts (Lines) + Nodes (Points) + Info.
Vertex to Centroid
Vertex to centroid (4 struts/tet).
Midpoint to Centroid
Edge midpoint to centroid (6 struts/tet).
FaceCenter to Centroid
Face center to adjacent centroids.
FaceCenter to EdgeMidpoint
Face center to face edge midpoints (12 struts/tet).
FaceCenter to FaceCenter
All pairs of face centers (6 struts/tet).
Midpoint to Midpoint
Opposite edge midpoints (3 struts/tet).
Corner to Opp FaceCenter
Vertex to opposite face center (4 struts/tet).
Corner to Opp EdgeMidpoint
Vertex to opposite edge midpoints (12 struts/tet).
Centroid to Centroid
Adjacent centroids through shared faces (Voronoi dual).
Edge Lattice
Tetrahedral edges deduplicated (6/tet).
Lattice Transition
Edge lattice to truncated tet blend.
