OrientedBoundingBoxTraits_3 Concept Reference

Definition

The concept OrientedBoundingBoxTraits_3 describes the requirements of the traits class used in the function CGAL::oriented_bounding_box(), and in particular the need for a 3x3 matrix type.

Refines:

Kernel

Has Models:

CGAL::Oriented_bounding_box_traits_3

Public Types
typedef unspecified_type	FT
	The field number type; must be a model of the concept FieldNumberType
typedef CGAL::Aff_transformation_3< K >	Aff_transformation_3
	The 3D affine transformation type; the template parameter K must be a model of Kernel and be compatible with the type Point_3
typedef unspecified_type	Matrix
	A 3x3 matrix type; model of the concept SvdTraits::Matrix and which supports matrix-matrix and scalar-matrix multiplication, as well as matrix-matrix addition.
typedef unspecified_type	Vector
	A 3 dimensional vector type; model of the concept SvdTraits::Vector and which supports matrix-vector and multiplication.
