Definition

The function object concept MeshEdgeCriteria_3 is designed to drive the process which samples the 1-dimensional features of the domain. It provides an upper bound for the distance between two protecting ball centers that are consecutive on a 1-feature.

Types
typedef unspecified_type	Point_3
	Point type.

typedef unspecified_type	Edge
	Type for edges of the triangulation.

typedef unspecified_type	FT
	Numerical type.

typedef unspecified_type	Index
	Feature index type.

Operations
FT	sizing_field (const Point_3 &p, const int dim, const Index &index)
	Returns the value of the sizing field (i.e., the maximum edge length) at point `p`, lying on subcomplex of dimension `dim` and index `index`.

const FT &	min_length_bound () const
	Returns the lower bound on edge length, set by the user.

FT	distance_field (const Point_3 &p, const int dim, const Index &index)
	Returns the value of the distance field (i.e., the maximum edge distance) at point `p` lying on subcomplex of dimension `dim` and index `index`.

bool	has_distance_field () const
	Returns whether or not the distance field should be checked during the protection phase.

Member Typedef Documentation

◆ Edge

typedef unspecified_type MeshEdgeCriteria_3::Edge

Type for edges of the triangulation.

Must match the Edge type in the triangulation type used by the mesh generation function.

◆ Point_3

typedef unspecified_type MeshEdgeCriteria_3::Point_3

Point type.

Must match the Point_3 type in the triangulation type used by the mesh generation function.

Member Function Documentation

◆ has_distance_field()

bool MeshEdgeCriteria_3::has_distance_field ( ) const

Returns whether or not the distance field should be checked during the protection phase.

If false, the distance field is ignored.

◆ min_length_bound()

const FT & MeshEdgeCriteria_3::min_length_bound ( ) const

Returns the lower bound on edge length, set by the user.

The lower bound is ignored when its value is 0.
