Detailed Description

template<typename Integer = int>
class DGtal::detail::PointOnProbingRay< Integer >

Description of template class 'PointOnProbingRay'

A ray consists of a permutation \( \sigma \) and an integer index \( \lambda \) (position on the ray). For a triplet of vectors \( (m_k)_{0 \leq k \leq 2} \) and a point \( q \), a point on the ray is defined as: \( q - m_{\sigma(0)} + m_{\sigma(1)} + \lambda m_{\sigma(2)} \). \( q - m_{\sigma(0)} + m_{\sigma(1)} \) is called the base point.

This class is used to represent points on rays for a plane-probing estimator, so in practice the point \( q \) is the fixed point and the three vectors \( (m_k)_{0 \leq k \leq 2} \) are the vectors defining the current probing frame.

getBase()

template<typename Integer = int>

PointOnProbingRay DGtal::detail::PointOnProbingRay< Integer >::getBase

(

)

const

Returns

the base point of the ray (with index 0).

index()

Integer const & DGtal::detail::PointOnProbingRay< Integer >::index

(

)

const

Returns

index of the current point on the ray.

next()

template<typename Integer = int>

PointOnProbingRay DGtal::detail::PointOnProbingRay< Integer >::next

(

Integer const &

aInc

)

const

Parameters

aInc	an increment.

Returns

a new point on a ray, with index the current index incremented by aInc.

operator!=()

template<typename Integer = int>

bool DGtal::detail::PointOnProbingRay< Integer >::operator!=

(

PointOnProbingRay< Integer > const &

aRay

)

const

Inequality test between two rays.

Parameters

aRay	an other ray.

(

PointOnProbingRay< Integer > const &

aRay

)

const

Equality test between two rays: the internal permutations and indices must be the same.

Parameters

aRay	an other ray.

Returns

true if the two rays are the same, false otherwise.

previous()

Permutation const & DGtal::detail::PointOnProbingRay< Integer >::sigma

(

)

const

Returns

the permutation that defines the ray.

sigma() [2/2]

template<typename Integer = int>

int DGtal::detail::PointOnProbingRay< Integer >::sigma

(

int

aIndex

const

Parameters

aIndex

an index between 0 and 2.
