CGAL 4.12.1 - 3D Alpha Shapes
|
The concept FixedAlphaShapeVertex_3
describes the requirements for the base vertex of a alpha shape with a fixed value alpha.
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::Fixed_alpha_shape_vertex_base_3
(templated with the appropriate triangulation vertex base class). Types | |
typedef unspecified_type | Point |
Must be the same as the point type provided by the geometric traits class of the triangulation. | |
