Enumeration Type Documentation

enum CGAL::Barycentric_coordinates::Query_point_location

Query_point_location is enumeration with possible locations of a query point provided by the user.

Enumerator
UNSPECIFIED_LOCATION	Location is not known apriori and is defined automatically by the algorithm.
ON_VERTEX	Query point is located at one of the polygon's vertices.
ON_BOUNDARY	Query point is located on the boundary of the polygon.
ON_BOUNDED_SIDE	Query point is located inside the polygon, excluding the boundary.
ON_UNBOUNDED_SIDE	Query point is located outside the polygon, excluding the boundary.

enum CGAL::Barycentric_coordinates::Type_of_algorithm

Type_of_algorithm is enumeration with possible algorithms to compute coordinates.

Enumerator
PRECISE	A default slow algorithm, which is as precise as possible.
FAST	A fast algorithm, which is less precise but much faster.
