CGAL 4.12 - Triangulated Surface Mesh Simplification

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<ECM>

CGAL::Surface_mesh_simplification::Count_ratio_stop_predicate<ECM>

CGAL::Surface_mesh_simplification::Edge_length_stop_predicate<FT>

Types

typedef unspecified_type ECM

 A field type representing the collapse cost.
 
typedef unspecified_type size_type
 An integer type representing the number of edges.
 
typedef unspecified_type Profile
 The type of the edge profile cache. More...
 

Operations

bool 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. More...

◆ ECM

The type of the surface mesh to simplify.

Must be a model of the EdgeCollapsableSurfaceMesh concept.

◆ Profile

The type of the edge profile cache.

Must be a model of the EdgeProfile concept.

◆ 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.
