Operations

void edge_node (Edge_handle e, Point_3 &pt)
 computes the edge-point pt based on the neighborhood of the edge e.
 
void vertex_node (Vertex_handle v, Point_3 &pt)
 computes the vertex-point pt based on the neighborhood of the vertex v.
 
void border_node (Halfedge_handle e, Point_3 &ept, Point_3 &vpt)
 computes the edge-point ept and the vertex-point vpt based on the neighborhood of the border edge e.
