Constructor & Destructor Documentation

UniformScaling ( )

inline

Default constructor without initialization.

Referenced by UniformScaling< _Scalar >::inverse(), and UniformScaling< _Scalar >::operator*().

UniformScaling ( const Scalar & s )

inlineexplicit

Constructs and initialize a uniform scaling transformation

UniformScaling ( const UniformScaling< OtherScalarType > & other )

Member Function Documentation

UniformScaling<NewScalarType> 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.

References UniformScaling< _Scalar >::m_factor.

const Scalar& factor ( ) const

inline

References UniformScaling< _Scalar >::m_factor.

Referenced by UniformScaling< _Scalar >::isApprox(), UniformScaling< _Scalar >::operator*(), RotationBase< Derived, 3 >::operator*(), Translation< _Scalar, _Dim >::operator*(), MatrixBase< Derived >::operator*(), Transform< _Scalar, _Dim, _Mode, _Options >::operator*(), Transform< _Scalar, _Dim, _Mode, _Options >::operator*=(), Transform< _Scalar, _Dim, _Mode, _Options >::operator=(), and UniformScaling< _Scalar >::UniformScaling().

Scalar& factor ( )

inline

References UniformScaling< _Scalar >::m_factor.

UniformScaling inverse ( ) const

inline

Returns:: the inverse scaling

References UniformScaling< _Scalar >::m_factor, and UniformScaling< _Scalar >::UniformScaling().

bool isApprox	(	const UniformScaling< _Scalar > &	other,
		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.

UniformScaling operator* ( const UniformScaling< _Scalar > & other ) const

inline

Concatenates two uniform scaling
