SortableEdge Class

  • For boundary sorting, an edge is a (packed!) Float64Array.
  • Fixed entry positions are:
    • [0] is start vertex index (in CCW order around its facet)
    • [1] is end vertex index (in CCW order around its facet)
    • [2] is facet index.

Extends

  • Float64Array

Methods

Name Description
constructor(vertexA: number, vertexB: number, facetIndex: number): SortableEdge    
toJSON(): any    
areDirectedPartners(edgeA: SortableEdge, edgeB: SortableEdge): boolean Static Return true if the vertices edgeA and edgeB are the same vertex indices in opposite order  
areUndirectedPartners(edgeA: SortableEdge, edgeB: SortableEdge): boolean Static Return true if the vertices edgeA and edgeB are the same vertex indices with no consideration of order  
clusterArrayToJSON(data: SortableEdgeCluster[]): any[] Static    
clusterToJSON(data: SortableEdgeCluster): any Static    
lessThan(edgeA: SortableEdge, edgeB: SortableEdge): number Static lexical comparison of two edges.  
relativeOrientation(edgeA: SortableEdge, edgeB: SortableEdge): number Static Return numeric relationship of edgeA and edgeB:
