CGAL 5.6.1 - 3D Alpha Shapes
FixedAlphaShapeCell_3 Concept Reference

Definition

The concept FixedAlphaShapeCell_3 describes the requirements for the base cell of a alpha shape with a fixed value alpha.

Refines
DelaunayTriangulationCellBase_3 if the underlying triangulation of the alpha shape is a Delaunay triangulation
RegularTriangulationCellBase_3 if the underlying triangulation of the alpha shape is a regular triangulation
Periodic_3TriangulationDSCellBase_3 if the underlying triangulation of the alpha shape is a periodic triangulation
Has Models:
CGAL::Fixed_alpha_shape_cell_base_3 (templated with the appropriate triangulation cell base class).
