#include <HalfLinksRefine_fwd.hpp>

Detailed Description

Refine a region of nodes region by connecting every node in region to its support domain and generating new nodes at half distances.

The new nodes are filtered to meet a minimum distance criterion to prevent points that would be too close.

Usage example:

    BoxShape<Vec2d> box(0, 1);
    auto domain = box.discretizeWithStep(0.2);
    domain.findSupport(FindClosest(9));
    int N = domain.size();
 
    auto region = domain.positions().filter(
            [](const Vec2d &v) { return v[0] < 0.35 && v[1] < 0.35; });
    HalfLinksRefine refine; refine.region(region);
    auto new_points = refine(domain);

◆ min_dist()

HalfLinksRefine& mm::HalfLinksRefine::min_dist ( double fraction )

inline

Minimal distance criterion around point p is that nodes generated at p must be at least fraction * closest_support_node away from all nodes.

Fraction must be less than 1/2. Default value is HalfLinksRefine::fraction_;

Definition at line 44 of file HalfLinksRefine_fwd.hpp.

◆ operator()() [1/2]

template<typename vec_t >

Range< int > mm::HalfLinksRefine::operator() ( DomainDiscretization< vec_t > & domain ) const

Refines given domain.

Returns: The indexes of the added nodes in positions.

Definition at line 19 of file HalfLinksRefine.hpp.

◆ operator()() [2/2]

template<typename vec_t >

Range< int > mm::HalfLinksRefine::operator()	(	DomainDiscretization< vec_t > &	domain,
		KDTreeMutable< vec_t > &	tree
	)		const

Refine the domain with already given tree.

Parameters

domain	Domain discretization object, which will be refined.
tree	A mutable KDTree, which contains all domain nodes. New nodes will be inserted.

Returns: The indexes of the added nodes in positions.

Definition at line 25 of file HalfLinksRefine.hpp.

◆ refine_impl()

template<class vec_t >

Range< int > mm::HalfLinksRefine::refine_impl	(	DomainDiscretization< vec_t > &	domain,
		const Range< int > &	region,
		double	fraction,
		KDTreeMutable< vec_t > &	domain_tree
	)

staticprivate

Refine implementation with more control over fine grained details.

Parameters

domain	Domain to refine.
region	A list of indices to refine.
fraction	Minimal distance fraction.
domain_tree	Tree containing all domain points.

Returns: List of indices of added nodes.

Definition at line 38 of file HalfLinksRefine.hpp.

◆ region()

HalfLinksRefine& mm::HalfLinksRefine::region ( Range< int > region )

inline

Set region to refine.

The region is a set of indices of the nodes to be refined. All nodes are refined by default.
