## Operations

void | facet_node (Facet_handle facet, Point_3 &pt)
| computes the facet-point `pt` based on the neighborhood of the facet `f`.
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`.
