Delaunay Beams

Connects a set of points into tetrahedra (Delaunay) and turns them into a lattice. Method picks what becomes beams: the tet edges (Edges), a fan from each face centre to its corners (Centroids), or face centres linked through edge midpoints (Dual). Needs at least four points.

Inputs

Vertices List of Point

The points to connect; at least four.

Takes: any block that gives Point (13 blocks)
Method Choice

Which parts of the tetrahedra become beams: Edges, Centroids (face centre to corners) or Dual (face centre to edge midpoints).

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)
Include surface Yes/No

Also build beams on the faces of the outer hull, not only inside. Off by default.

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.

Beams List of Beam

Every beam, each with its own properties.

Solid Solid

All the thickened beams merged into one Solid; beams with no thickness yet are the distance to their segments.

List List of Lattice

This lattice in a Lattice List of one.

BeamGraph Beam Graph

The beams, vertices and thicknesses, without the lattice around them.

Graph Lattice

The beams and vertices alone, with no thickness.

BoundingBox Bounding Box

The axis-aligned extent of the beams' vertices.

EdgeCount Number

How many beams the lattice has.

LineSegments List of Curve

Each beam as a line segment.

VertexCount Number

How many vertices the lattice has.

VertexValencies List of Number

For each vertex, the number of beams that end there.

Vertices List of Point

The position of every vertex.
