An equilateral triangular lattice of points. (Shown as Tri Grid on the canvas.)

Category: Primitives | Add menu: Primitives > Tri Grid

Like Rectangular Grid, but with a single spacing: each row is staggered by half a step and set at the equilateral height, so every cell is an equilateral triangle. Like Grid it has two outputs: Points, the bare lattice, and Segments, the mesh edges in all three directions.

• Count X (number): points per row.
• Count Y (number): number of rows.
• Spacing (number): the single step, in mm; both the horizontal pitch and (via the equilateral height) the row spacing derive from it.
• Lattice V1 (any): optional. Aims and anchors the lattice, and the row stagger rides along with it.
• Spacing Override (boolean): take the step from V1's own length instead of the Spacing number. Off by default.

• Segments (curve): the mesh edges, all three directions.
• Points (point): the bare triangular lattice.

Wire a vector into Lattice V1 and the lattice moves onto it: the first point lands on the vector's start and the first axis runs along the vector. The half-step stagger and the equilateral row height ride along with it, so the mesh stays equilateral however the vector is turned. Unwired, the lattice sits axis-aligned on the origin.

There is only one lattice vector here, because there is only one spacing: the equilateral cell fixes the second direction. With Spacing Override on, that single step comes from V1's length, and a vector with no usable length leaves the Spacing number standing.

Lattice V1 reads a segment (a to b), a ray (direction only), or two points (first to second).

• Rectangular Grid: the rectangular case.
• Oblique Grid: two arbitrary directions, for parallelogram, rhombic and hexagonal cells.
