Detailed Description

template<class T>
class Vector2< T >

A templatized 2d vector compatible with OpenGL.

Use Vec2i for integer and Vec2d or Vec2f typedef for vectors of double and float respectively.

Constructor & Destructor Documentation

◆ Vector2() [1/3]

template<class T >
Vector2< T >::Vector2 ( x = 0)
inlineexplicit

The vector is not initialized!

Sets all components of the vector to the same value

◆ Vector2() [2/3]

template<class T >
Vector2< T >::Vector2 ( const T *  x)
inlineexplicit

Explicit conversion constructor from an array (copies values)

Warning
Does not check array size, make sure it has at least 2 elements

◆ Vector2() [3/3]

template<class T >
template<class T2 >
Vector2< T >::Vector2 ( const Vector2< T2 > &  other)
inlineexplicit

Explicit conversion constructor from another Vec2 of any type.

Uses default primitive type conversion

Member Function Documentation

◆ toStr()

template<class T >
QString Vector2< T >::toStr ( ) const

Compact comma-separated string without brackets and spaces.

The result can be restored into a Vector2 by the Vector2(QString s) constructors.
