segments

schema/components/segments/1.2.0/segments.schema.json

The segments component defines a set of line segments by pairs of vertex indices.

vertices — An N×3 array of 3D coordinates defining the vertex positions.
indices — An M×2 index-array-2 of (start, end) vertex pairs, each defining one segment. Indices are 0-based and reference positions in the vertices array.

An optional attribute list can be associated with both vertices and indices, allowing per-vertex and per-segment properties.

Used by: line-segments, triangle-mesh.

See also: triangles, quadrilaterals, hexahedrons, tetrahedra (other cell types).

Properties

Segments are defined by pairs of indices into the vertices list.

Property	Type	Description	Flags
vertices	segments	Vertex coordinates. Columns: x, y, z.	✅
indices	segments	0-based indices into the vertices. Each pair is a segment. Columns: n0, n1.	✅
