API Reference > geometry-core > Topology > Triangulator > createFaceLoopFromCoordinatesAndMasks createFaceLoopFromCoordinatesAndMasks MethodStatic create a circular doubly linked list of internal and external nodes from polygon points. Optionally jump to the "other" side so the returned loop has positive area createFaceLoopFromCoordinatesAndMasks(graph: , data: LineStringDataVariant, returnPositiveAreaLoop: boolean, maskForBothSides: , maskForOtherSide: ): undefined | Parameter Type Description graph graph to receive the new edges data LineStringDataVariant array with x,y coordinates returnPositiveAreaLoop boolean if false, return an edge proceeding around the loop in the order given. If true, compute the loop area and flip return the side with positive area. maskForBothSides mask to apply on both sides. maskForOtherSide mask to apply on the "other" side from the returned loop. Returns - undefined | Defined in topology/Triangulation.ts Line 404 Last Updated: 11 June, 2024
