Concept

TriangulationHierarchyVertexBase_2

Definition

The vertex of a triangulation included in a triangulation hierarchy has to provide some pointers to the corresponding vertices in the triangulations of the next and preceding levels. Therefore, the concept TriangulationHierarchyVertexBase_2 refines the concept TriangulationVertexBase_2, adding handles to the corresponding vertices in the next and previous level triangulations.

Refines

TriangulationVertexBase_2

Operations

Vertex_handle v.up () returns the corresponding vertex (if any) of the next level triangulation;
Vertex_handle v.down () returns the corresponding vertex of the previous level triangulation;
void v.set_up ( Vertex_handle u) sets the handle pointing to to the corresponding vertex of the next level triangulation;
void v.set_down ( Vertex_handle d) sets the handle pointing to the corresponding vertex of the previous level triangulation;
