Detailed Description

template<class DT>
class ml::Tvec2< DT >

Declaration of float vector type traits:

Forward declarations to resolve header file dependencies.

A two dimensional vector class for floating point types.

Member Typedef Documentation

◆ ComponentType

template<class DT >
typedef DT ml::Tvec2< DT >::ComponentType

A typedef to "export" the type of components.

Definition at line 64 of file mlVector2.h.

◆ Superclass

template<class DT >
typedef FloatingPointVector<DT, 2, Vector2DataContainer<DT> > ml::Tvec2< DT >::Superclass

A typedef as a shorthand for the base class.

Definition at line 61 of file mlVector2.h.

Constructor & Destructor Documentation

◆ Tvec2() [1/5]

template<class DT >
ml::Tvec2< DT >::Tvec2 ( const DT value = 0)
inlineexplicit

Default and value constructor.

Set all entries to a user given value. value is the init value for all entries. 0 is the default value.

Definition at line 72 of file mlVector2.h.

◆ Tvec2() [2/5]

template<class DT >
ml::Tvec2< DT >::Tvec2 ( const Superclass & v)
inline

Copy constructor from FloatingPointVector.

This allows the usage of SclarVectorTemplate objects of the same DT in operators using the Tvec2, because the FloatingPointVector objects can implicitly be cast.

Definition at line 79 of file mlVector2.h.

◆ Tvec2() [3/5]

template<class DT >
ml::Tvec2< DT >::Tvec2 ( const DT px,
const DT py )
inline

Constructor building the vector x (first entry) and y (second entry).

Definition at line 84 of file mlVector2.h.

References mlrange_cast().

◆ Tvec2() [4/5]

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

Casts v to Tvec2.

If normalize is true then the first two 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 if false then the first two components are taken unchanged.

Definition at line 100 of file mlVector2.h.

References ML_CHECK_FLOAT_THROW.

◆ Tvec2() [5/5]

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

Casts v3 to v2.

axis specifies component to be thrown away. All other components are copied sequentially. If axis is not within [0,2] then the last component is thrown away.

◆ affineVec()

template<class DT >
Tvec3< DT > ml::Tvec2< DT >::affineVec ( ) const

void ml::Tvec2< DT >::assign ( const DT px,
const DT py )
