StopPredicate Concept Reference

Definition

The concept StopPredicate describes the requirements for the predicate which indicates if the simplification process must finish.

Has Models:

CGAL::Surface_mesh_simplification::Count_stop_predicate<TriangleMesh>

CGAL::Surface_mesh_simplification::Count_ratio_stop_predicate<TriangleMesh>

CGAL::Surface_mesh_simplification::Edge_length_stop_predicate<FT>

Types

	An integer type representing the number of edges.
typedef unspecified_type	Profile
	The type of the edge profile cache. More...

Operations

Member Typedef Documentation

Profile

typedef unspecified_type StopPredicate::Profile

The type of the edge profile cache.

Must be a model of the EdgeProfile concept.

TriangleMesh

typedef unspecified_type StopPredicate::TriangleMesh

The type of the surface mesh to simplify.

Must be a model of the MutableFaceGraph and HalfedgeListGraph concepts.

operator()()

bool StopPredicate::operator()	(	FT const &	current_cost,
		Profile const &	profile,
		size_type	initial_count,
		size_type	current_count
	)		const

This predicate is called each time an edge is selected for processing, before it is collapsed.

current_cost is the cost of the selected edge.

initial_count and current_count are the number of initial and current edges.

If the return value is true the simplification terminates before processing the edge, otherwise it continues normally.
