Detailed Description

template<class DT>
class ml::Tvec3< DT >

Forward declarations to resolve header file dependencies.

A three dimensional vector class for floating point types.

Definition at line 65 of file mlVector3.h.

Member Typedef Documentation

◆ ComponentType

template<class DT>
typedef DT ml::Tvec3< DT >::ComponentType

A typedef to 'export' the type of components.

Definition at line 74 of file mlVector3.h.

◆ Superclass

template<class DT>
typedef FloatingPointVector<DT, 3, Vector3DataContainer<DT> > ml::Tvec3< DT >::Superclass

A typedef as a shorthand for the base class.

Definition at line 71 of file mlVector3.h.

Constructor & Destructor Documentation

◆ Tvec3() [1/6]

template<class DT>
ml::Tvec3< DT >::Tvec3 ( const DT value = 0)
inlineexplicit

Default and value constructor. Sets all entries to a user given value. value is the init value for all entries. 0 is the default value.

Definition at line 82 of file mlVector3.h.

◆ Tvec3() [2/6]

template<class DT>
ml::Tvec3< DT >::Tvec3 ( const Superclass & v)
inline

Copy constructor from FloatingPointVector. This allows the usage of SclarVectorTemplate objects of the same DT in operators using the Tvec3, because the FloatingPointVector objects can implicitly be cast.

Definition at line 89 of file mlVector3.h.

◆ Tvec3() [3/6]

template<class DT>
ml::Tvec3< DT >::Tvec3 ( const DT px,
const DT py,
const DT pz )
inline

Constructor building the vector px, py, and pz.

Definition at line 94 of file mlVector3.h.

◆ Tvec3() [4/6]

template<class DT>
ml::Tvec3< DT >::Tvec3 ( const Tvec2< DT > & v,
const DT pz )
inline

Builds a Tvec3 from a Tvec2 and a scalar. Sets the third entry to user given value pz.

Definition at line 102 of file mlVector3.h.

◆ Tvec3() [5/6]

template<class DT>
ml::Tvec3< DT >::Tvec3 ( const Tvec4< DT > & v,
const bool normalizeV )
inline

Casts a Tvec4 v to Tvec3. If normalize is true, then the first three components are divided by the last one to implement a homogeneous cast. In that case, it is up to the caller to avoid a division by zero. If normalize is false, then the first three components are taken unchanged.

Definition at line 114 of file mlVector3.h.

◆ Tvec3() [6/6]

template<class DT>
ml::Tvec3< DT >::Tvec3 ( const Tvec4< DT > & v,
const int axis )
inline

Casts a Tvec4 v to Tvec3. axis specifies component to be thrown away. All other components are copied sequentially. If axis is not within [0,3], then the last component is thrown away.

Definition at line 143 of file mlVector3.h.

Member Function Documentation

◆ affinePoint()

template<class DT>
Tvec4< DT > ml::Tvec3< DT >::affinePoint ( ) const
inline

Builds a homogeneous Tvec4 point from *this and returns it, i.e., leaves all components unchanged and sets the fourth component to 1.

Definition at line 203 of file mlVector3.h.

Referenced by ml::operator*(), and ml::Tmat4< MLfloat >::transformPoint().

◆ affineVec()

template<class DT>
Tvec4< DT > ml::Tvec3< DT >::affineVec ( ) const
inline

Builds a homogeneous Tvec4 vector from *this and returns it, i.e., leaves all components unchanged and sets the fourth component to 0.

Definition at line 196 of file mlVector3.h.

◆ assign()

template<class DT>
void ml::Tvec3< DT >::assign ( const DT px,
const DT py,
const DT pz )
inline

Sets all components to the passed values.

Definition at line 171 of file mlVector3.h.

Referenced by ml::PCLSupportTools::getBoxForPointCloud(), and ml::PCLMLTools::transformTo().

◆ divideByLastComp()

template<class DT>
Tvec3< DT > ml::Tvec3< DT >::divideByLastComp ( ) const
inline

Divides all vector components by its last component and returns it as Tvec3, which then has a 1 as last component. It is useful to scale the vector from homogeneous space to normal space. It is up to the caller to avoid a division by zero if last component is 0.
