## Definition

The concept `ImplicitFunction` describes a function object whose `operator()` computes the values of a function \( f : \mathbb{R}^3 \longrightarrow \mathbb{R}\).

Has Models:

  CGAL::Gray_level_image_3

  any pointer to a function of type `FT (*)(Point)`

See also
  `CGAL::Implicit_surface_3<Traits, Function>`
  `CGAL::make_surface_mesh()`

## Types
The following types aren't required for any pointer to a function of type `FT (*)(Point)`.
typedef unspecified_type | FT
| Number type.
typedef unspecified_type | Point
| Point type.

## Operations
FT | operator() (Point p)
| Returns the value \( f(p)\), where \( p \in\mathbb{R}^3\).
