CGAL 5.4.4  3D Alpha Shapes

The concept AlphaShapeVertex_3
describes the requirements for the base vertex of an alpha shape.
TriangulationVertexBase_3
, if the underlying triangulation of the alpha shape is a Delaunay triangulation.
RegularTriangulationVertexBase_3
, if the underlying triangulation of the alpha shape is a regular triangulation.
Periodic_3TriangulationDSVertexBase_3
, if the underlying triangulation of the alpha shape is a periodic triangulation.
CGAL::Alpha_shape_vertex_base_3
(templated with the appropriate triangulation vertex base class).CGAL::Alpha_status
Types  
typedef unspecified_type  Point 
Must be the same as the point type provided by the geometric traits class of the triangulation.  
typedef unspecified_type  Alpha_status 
Must be CGAL::Alpha_status<NT> where NT is the number type used in the geometric traits class of the triangulation.  
Creation  
AlphaShapeVertex_3 ()  
default constructor.  
AlphaShapeVertex_3 (Point p)  
constructor setting the point.  
AlphaShapeVertex_3 (Point p, const Cell_handle &c)  
constructor setting the point and an incident cell.  
Modifiers  
Alpha_status *  get_alpha_status () 
Returns a pointer the alpha status of the vertex.
