API Reference > geometry-core > Topology > Triangulator > createFaceLoopFromCoordinates createFaceLoopFromCoordinates MethodStatic create a circular doubly linked list of internal and external nodes from polygon points in the specified winding order This applies the masks used by typical applications: HalfEdgeMask.BOUNDARY on both sides HalfEdgeMask.PRIMARY_EDGE on both sides. Use createFaceLoopFromCoordinatesAndMasks for detail control of masks. createFaceLoopFromCoordinates(graph: , data: LineStringDataVariant, returnPositiveAreaLoop: boolean, markExterior: boolean): | undefined Parameter Type Description graph data LineStringDataVariant returnPositiveAreaLoop boolean markExterior boolean Returns - | undefined Defined in core/geometry/src/topology/Triangulation.ts Line 383 Last Updated: 13 June, 2024
