Detailed Description

template<class T>
class Vector2< T >

A templatized 2d vector compatible with openGL.

Use Vec2d or Vec2f typdef for vectors of double and float respectively.

Definition at line 32 of file VecMath.hpp.

Constructor & Destructor Documentation

template<class T >
Vector2< T >::Vector2 ( )
inline

The vector is not initialized!

Definition at line 441 of file VecMath.hpp.

template<class T>
Vector2< T >::Vector2 ( x)
inline

Sets all components of the vector to the same value.

Definition at line 443 of file VecMath.hpp.

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

Definition at line 448 of file VecMath.hpp.

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

Definition at line 453 of file VecMath.hpp.
