Definition

The concept SimplicialMeshVertexBase_3 describes the requirements for the Vertex type of the triangulation used in the 3D simplicial mesh data structure. The type SimplicialMeshVertexBase_3 refines the concept TriangulationVertexBase_3. It provides additional members to store and retrieve information about the location of the vertex with respect to the input domain describing the discretized domain. More specifically, the concept SimplicialMeshVertexBase_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.
