CGAL 5.4  3D Mesh Generation

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 both the concept RegularTriangulationVertexBase_3
and the concept 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 readwrite 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 readwrite 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).
