quadrilaterals

schema/components/quadrilaterals/1.2.0/quadrilaterals.schema.json

The quadrilaterals component defines a set of quadrilateral cells by their vertices and connectivity.

vertices — An array of 3D coordinates.
indices — An index array of vertex quadruplets, each defining a quadrilateral face. Indices are 0-based.

The vertex coordinate columns follow the axis order declared in the object's coordinate_reference_system — see Coordinate reference systems and axis order.

Used by: unstructured-quad-grid.

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