MeshVertexBase_3 Concept Reference

Definition

The concept MeshVertexBase_3 describes the requirements for the Vertex type of the triangulation used by a 3D mesh generation process. The type MeshVertexBase_3 refines the concepts RegularTriangulationVertexBase_3, SimplicialMeshVertexBase_3, and SurfaceMeshVertexBase_3. It provides additional members to store and retrieve information about the location of the vertex with respect to the input domain describing the domain to be discretized. More specifically, the concept MeshVertexBase_3 provides read-write access to an integer representing the dimension of the lowest dimensional face of the input 3D complex on which the vertex lies, and to an index characteristic of this face. The concept MeshVertexBase_3 provides storage and read-write access to a boolean, a FT value, and two Vertex_handle called 'intrusive'.

The parallel algorithms require an erase counter in each cell (see below).
