CGAL::Simple_cartesian<FieldNumberType>

Definition

A model for a Kernel using Cartesian coordinates to represent the geometric objects. In order for Simple_cartesian<FieldNumberType> to model Euclidean geometry in

E² and/or

E³, for some mathematical field

E (e.g., the rationals

or the reals

), the template parameter FieldNumberType must model the mathematical field

E. That is, the field operations on this number type must compute the mathematically correct results. If the number type provided as a model for FieldNumberType is only an approximation of a field (such as the built-in type double), then the geometry provided by the kernel is only an approximation of Euclidean geometry.

Types

typedef FieldNumberType
	FT;
typedef FieldNumberType
	RT;

Implementation

In contrast to Cartesian, no reference counting is used internally. This eases debugging, but may slow down algorithms that copy objects intensively.
