The lattice consists of triangles that maximize the minimum angle in each triangle. Tetrahedralization requires at least four points to run.

Choose from the following lattice creation methods: * **Mesh edges:** Creates lattice beams along the mesh edges. * **Vertex Centroid:** Creates a vertex at each mesh face's centroid and the mesh vertices. Lattice beams connect the vertices. * **Dual:** Creates a vertex at the centroid of each mesh face and creates a connecting beam to the next closest mesh centroid.

## Stochastic Lattice Types Since maximizing minimum angles prevents long beams, the resulting Delaunay structures are typically stiff. The result is a stochastic, stiff lattice. In contrast, the Voronoi lattice is typically softer/ more flexible.
