    Modifier and Type
    Method
    Description
    private void
    addBoundaryEdges(Polyhedron_3<X> mesh)
    Add and set boundary half-edges to the representation Remark: it allows to deal with meshes having boundaries
    Polyhedron_3<X>
    createMesh(X[] points, int[] faceDegrees, int[][] faces)
    Efficient construction of a Polyhedron (Half-edge DS) for a surface mesh (from a share vertex representation)

    Remark: it works for arbitrary polygonal meshes,possibly having boundaries
    (package private) Polyhedron_3<X>
    createMeshOld(X[] points, int[] faceDegrees, int[][] faces)
    Efficient construction of a polyhedral mesh (Half-edge DS) (from a share vertex representation)
    private Halfedge<X>
    getNextBoundaryHalfedge(Halfedge<X> e)
    Given a boundary half-edge e, returns the next boundary half-edge around the same face Warning: the mesh is supposed to be manifold (boundary cycles are disjoint)
    static Point_2[]
    Point3DToPoint2D(Point_3[] points)
    Convert an array of 3D points to an array of 2D points (by orthogonal projection on the z=0 hyperplane)
    private String
    printEdge(Halfedge<X> e)
    Print the edge (the index of its extremities) Useful for debugging
