CGAL 5.5.2 - 2D Polyline Simplification
CGAL::Polyline_simplification_2 Namespace Reference

Classes

class  Hybrid_squared_distance_cost
 This class is a cost function which calculates the cost as the square of the distance between the original and simplified polylines, possibly scaled based on a factor. More...
 
class  Polyline_simplification_2
 
class  Scaled_squared_distance_cost
 This class is a cost function which calculates the cost as a scaled variant of the square of the distance between the original and simplified polylines. More...
 
class  Squared_distance_cost
 This class is a cost function which calculates the cost as the square of the distance between the original and simplified polylines. More...
 
class  Stop_above_cost_threshold
 This class is a stop predicate returning true when the cost for simplifying a vertex is greater than a certain threshold. More...
 
class  Stop_below_count_ratio_threshold
 This class is a stop predicate returning true when the percentage of remaning vertices is smaller than a certain threshold. More...
 
class  Stop_below_count_threshold
 This class is a stop predicate returning true when the number of vertices is smaller than a certain threshold. More...
 
class  Vertex_base_2
 A vertex base class with data members needed by the simplification algorithm. More...
