Function makeEdgesFacesSide3D

  • makeEdgesFacesSide3D(graph, edgesLine-facesPlane-data): number[][]

  • Parameters

    • graph: FOLDExtended

      a FOLD object where, if faces_center exists then only edges_faces is needed, otherwise vertices and face data is needed.

    • edgesLine-facesPlane-data: {
          edges_line: number[];
          faces_plane: number[];
          lines: VecLine[];
          planes_transform: number[][];
      }

      the joined-results from getEdgesLine() and getFacesPlane()

      • edges_line: number[]
      • faces_plane: number[]
      • lines: VecLine[]
      • planes_transform: number[][]

    Returns number[][]

    for every edge, for each of its 1 or 2 adjacent faces, a +1 or -1 for each face indicating which side of the edge the face lies on.

    Description

    For every edge, for each of its 1 or 2 adjacent faces, get which side of the edge this face lies on. All collinear edges are established to have a similar direction for sidedness, and this method works in 3D.
