## Definition

template<typename RingNumberType>
class CGAL::Homogeneous_d< RingNumberType >

A model for a `Kernel_d` (and even `KernelWithLifting_d`) using homogeneous coordinates to represent the geometric objects.

In order for `Homogeneous` to model Euclidean geometry in \( E^d\), for some mathematical ring \( E\) (e.g., the integers \(\mathbb{Z}\) or the rationals \(\mathbb{Q}\)), the template parameter `RT` must model the mathematical ring \( E\). That is, the ring operations on this number type must compute the mathematically correct results. If the number type provided as a model for `RingNumberType` is only an approximation of a ring (such as the built-in type `double`), then the geometry provided by the kernel is only an approximation of Euclidean geometry.

Is Model Of:
  `KernelWithLifting_d`
