## Definition

The class `Alpha_shape_cell_base_3` is the default model for the concept `AlphaShapeCell_3`.

Template Parameters

  Traits | is the geometric traits class that is provided to the `Alpha_shape_3` class.
  Cb | must be a cell base class instantiated by default with `Triangulation_cell_base_3<Traits>`.
  ExactAlphaComparisonTag | is a tag that, when set to `Tag_true`, triggers exact comparisons between alpha values. See the description provided in the documentation of `Alpha_shape_3` for more details. The default value is `Tag_false`.
  WeightedTag | is used only if `ExactAlphaComparisonTag` is `Tag_true`. It must be `Tag_true` if the underlying triangulation of the alpha shape to be used is a Regular triangulation and `Tag_false` otherwise. The default is `Tag_false`.
