API Reference > geometry-core > Topology > HalfEdgeGraphSearch > collectExtendedBoundaryLoopsInGraph collectExtendedBoundaryLoopsInGraph MethodStatic Collect arrays of nodes "around the boundary" of a graph with extraneous (non-boundary) edges. The "boundary" is nodes that do NOT have the exterior mask, but whose mates DO have the exterior mask. After each node, the next candidate in reached by looking "around the head vertex loop" for the next boundary. "Around the vertex" from nodeA means First look at nodeA.faceSuccessor; Then look at vertexPredecessor around that vertex loop. Each accepted node is passed to announceNode, and marked with the visit mask. collectExtendedBoundaryLoopsInGraph(graph: , exteriorMask: ): [][] Parameter Type Description graph exteriorMask Returns - [][] Defined in topology/HalfEdgeGraphSearch.ts Line 297 Last Updated: 11 June, 2024
