Concept SurfaceMeshCellBase_3: DelaunayTriangulationCellBase_3
Concept SurfaceMeshVertexBase_3: TriangulationVertexBase_3 The surface mesher algorithm issues frequent queries about the status of the vertices with respect to the two dimensional complex that represents the current surface approximation. The class SurfaceMeshVertexBase_3 offers a caching mechanism to answer more efficiently these queries. The caching mechanism includes two cached integers, which, when they are valid, store respectively the number of complex facets incident to the vertex and the number of connected components of the adjacency graph of those facets.
