SortableEdge Class

Represent an IndexedPolyface edge as:

  • vertex start index and vertex end index (CCW order around its facet)
  • an additional number to associate with the edge (e.g., facet index)

Methods

Name Description
constructor(startVertex: number, endVertex: number, facetIndex: number): SortableEdge Constructor.  
clone(): SortableEdge Clone the edge.  
toJSON(): any Return the edge data as a JSON array.  
areDirectedPartners(edgeA: SortableEdge, edgeB: SortableEdge): boolean Static Return true if edgeA and edgeB traverse the same edge in opposite directions.  
areUndirectedPartners(edgeA: SortableEdge, edgeB: SortableEdge): boolean Static Return true if edgeA and edgeB traverse the same edge in the same or opposite directions.  
clusterArrayToJSON(data: SortableEdgeCluster[]): any[] Static Return the edge cluster array in JSON format.  
clusterToJSON(data: SortableEdgeCluster): any Static Return the edge cluster in JSON format.  
lessThan(edgeA: SortableEdge, edgeB: SortableEdge): number Static Lexical comparison of two edges.  
relativeOrientation(edgeA: SortableEdge, edgeB: SortableEdge): number Static Return numeric identifier for the relationship between edgeA and edgeB:
