Definition

The concept SkinSurface_3 defines a skin surface and provides an interface for the dedicated skin surface mesher. The concept requires a constructor from an iterator range of weighted points and a shrink factor. By default the input balls are grown in such that the skin surface wraps around the input balls.

Has Models:

CGAL::Skin_surface_3<SkinSurfaceTraits_3>

CGAL::Union_of_balls_3<SkinSurfaceTraits_3>

Types
typedef unspecified_type	Geometric_traits
	The geometric traits used for the construction of the regular triangulation.

typedef Geometric_traits::Weighted_point_3	Weighted_point
	The `Weighted_point` type.

typedef Geometric_traits::Point_3	Bare_point
	The `Bare_point` type.

typedef unspecified_type	FT
	The `FT` type defined by the `Geometric_traits`.

Creation
template<class WP_iterator >
	Skin_surface_3 (WP_iterator begin, WP_iterator end, RT shrink_factor)
	The mandatory arguments to the constructor are an iterator range `[begin,end)` of weighted points and a shrink factor between 0 and 1.

Operations
template<class Polyhedron >
void	mesh_skin_surface_3 (Polyhedron &p)
	Constructs a coarse mesh in `p`.

template<class Polyhedron >
void	subdivide_skin_surface_mesh_3 (Polyhedron &p, int nSubdiv=1)
	Subdivides the skin surface using `nSubdiv` 1-4 split operations (each triangle is split into four sub-triangles) and the new vertices are moved towards the skin surface.

Member Typedef Documentation

◆ FT

typedef unspecified_type SkinSurface_3::FT

The FT type defined by the Geometric_traits.

This is the number type used by the weighted points.

Member Function Documentation

◆ mesh_skin_surface_3()

template<class Polyhedron >

void SkinSurface_3::mesh_skin_surface_3 ( Polyhedron & p )

Constructs a coarse mesh in p.

Template Parameters

Polyhedron must be an instance of Polyhedron_3.

Precondition: Polyhedron::HDS can be used as the template argument of the CGAL::Polyhedron_incremental_builder_3<HDS>.

◆ subdivide_skin_surface_mesh_3()

template<class Polyhedron >

void SkinSurface_3::subdivide_skin_surface_mesh_3	(	Polyhedron &	p,
		int	nSubdiv = `1`
	)

Subdivides the skin surface using nSubdiv 1-4 split operations (each triangle is split into four sub-triangles) and the new vertices are moved towards the skin surface.
