Constructor & Destructor Documentation

◆ Tvec4() [1/5]

template<class DT >

ml::Tvec4< DT >::Tvec4 ( const DT value = 0 )

inlineexplicit

Default and value constructor. Sets all entries to a user given value.

◆ Tvec4() [2/5]

template<class DT >

ml::Tvec4< DT >::Tvec4 ( const Superclass & v )

inline

Copy constructor from FloatingPointVector.

This allows the usage of SclarVectorTemplate objects of the same DT in operators using the Tvec4, because the FloatingPointVector objects can implicitly be cast.

Definition at line 71 of file mlVector4.h.

◆ Tvec4() [3/5]

template<class DT >

ml::Tvec4< DT >::Tvec4	(	const DT	x,
		const DT	y,
		const DT	z,
		const DT	w
	)

inline

Builds the vector from the scalars x, y, z and w to the components 0 to 3, respectively.

Definition at line 77 of file mlVector4.h.

◆ Tvec4() [4/5]

template<class DT >

ml::Tvec4< DT >::Tvec4	(	const Tvec2< DT > &	v,
		const DT	z,
		const DT	w
	)

inline

Casts Vector2 to Tvec4. Sets last two entries are given by z and w.

Definition at line 86 of file mlVector4.h.

◆ Tvec4() [5/5]

template<class DT >

ml::Tvec4< DT >::Tvec4	(	const Tvec3< DT > &	v,

◆ assign()

template<class DT >

void ml::Tvec4< DT >::assign	(	const DT	x,
		const DT	y,
		const DT	z,
		const DT	c
	)

inline

Sets all components to the passed values.

Definition at line 104 of file mlVector4.h.

◆ divideByLastComp()

template<class DT >

Tvec4<DT> ml::Tvec4< DT >::divideByLastComp ( ) const

inline

Divides all vector components by its last component and returns it as Tvec4 which then has a 1 as last component.

It is useful to scale the vector from homogeneous space to normal space. It's up to the caller to avoid a division by zero if last component is 0.
