Detailed Description

template<typename _Scalar, int _AmbientDim, int _Options>
class Eigen::ParametrizedLine< _Scalar, _AmbientDim, _Options >

A parametrized line

A parametrized line is defined by an origin point \( \mathbf{o} \) and a unit direction vector \( \mathbf{d} \) such that the line corresponds to the set \( l(t) = \mathbf{o} + t \mathbf{d} \), \( t \in \mathbf{R} \).

Template Parameters

_Scalar	the scalar type, i.e., the type of the coefficients
_AmbientDim	the dimension of the ambient space, can be a compile time value or Dynamic.

Constructor & Destructor Documentation

§ ParametrizedLine() [1/2]

template<typename _Scalar, int _AmbientDim, int _Options>

EIGEN_DEVICE_FUNC Eigen::ParametrizedLine< _Scalar, _AmbientDim, _Options >::ParametrizedLine	(	const VectorType &	origin,
		const VectorType &	direction
	)

inline

Initializes a parametrized line of direction direction and origin origin.

Warning: the vector direction is assumed to be normalized.

§ ParametrizedLine() [2/2]

template<typename _Scalar , int _AmbientDim, int _Options>

template<int OtherOptions>

EIGEN_DEVICE_FUNC Eigen::ParametrizedLine< _Scalar, _AmbientDim, _Options >::ParametrizedLine ( const Hyperplane< _Scalar, _AmbientDim, OtherOptions > & hyperplane )

inlineexplicit

Constructs a parametrized line from a 2D hyperplane.

Warning: the ambient space must have dimension 2 such that the hyperplane actually describes a line

Member Function Documentation

§ cast()

template<typename _Scalar, int _AmbientDim, int _Options>

template<typename NewScalarType >

EIGEN_DEVICE_FUNC internal::cast_return_type<ParametrizedLine, ParametrizedLine<NewScalarType,AmbientDimAtCompileTime,Options> >::type Eigen::ParametrizedLine< _Scalar, _AmbientDim, _Options >::cast ( ) const

inline

Returns: *this with scalar type casted to NewScalarType

Note that if NewScalarType is equal to the current scalar type of *this then this function smartly returns a const reference to *this.

§ dim()

template<typename _Scalar, int _AmbientDim, int _Options>

EIGEN_DEVICE_FUNC Index Eigen::ParametrizedLine< _Scalar, _AmbientDim, _Options >::dim ( ) const

inline

Returns: the dimension in which the line holds

§ distance()

template<typename _Scalar, int _AmbientDim, int _Options>

EIGEN_DEVICE_FUNC RealScalar Eigen::ParametrizedLine< _Scalar, _AmbientDim, _Options >::distance ( const VectorType & p ) const

inline

Returns: the distance of a point p to its projection onto the line *this.

EIGEN_DEVICE_FUNC bool Eigen::ParametrizedLine< _Scalar, _AmbientDim, _Options >::isApprox	(	const ParametrizedLine< _Scalar, _AmbientDim, _Options > &	other,
		const typename NumTraits< Scalar >::Real &	prec = `NumTraits<Scalar>::dummy_precision()`
	)		const

inline

Returns: true if *this is approximately equal to other, within the precision determined by prec.

inline

Returns: the projection of a point p onto the line *this.

§ squaredDistance()

template<typename _Scalar, int _AmbientDim, int _Options>

EIGEN_DEVICE_FUNC RealScalar Eigen::ParametrizedLine< _Scalar, _AmbientDim, _Options >::squaredDistance ( const VectorType & p ) const

inline

Returns: the squared distance of a point p to its projection onto the line *this.
