Detailed Description

template<typename TSpace>
class DGtal::DigitalPlanePredicate< TSpace >

Aim: Representing digital planes, which are digitizations of Euclidean planes, as point predicates.

Description of template class 'DigitalPlanePredicate'

A digital plane is a digitization of a Euclidean plane, it can be seen as the set of digital points comprised between two parallel Euclidean planes.

If N is a normal vector, \( \mu \) the lower bound and \( \nu \) the thickness then the corresponding digital plane is the set of digital points \( x \) such that \( \mu \leq x \cdot N < \mu + \nu \).

When \( \nu = \| N \|_1 \), then it represents a standard digital plane, and when \( \nu = \| N \|_\infty \), then it represents a naive digital plane.

Template Parameters

TSpace

any digital space, i.e., a model of CSpace.

Models: A DigitalPlanePredicate is a model of concepts::CPointPredicate.
