Detailed Description

template<typename Type>
class Vector2Tpl< Type >

2D Vector

Constructor & Destructor Documentation

Vector2Tpl() [1/2]

template<typename Type >

Vector2Tpl< Type >::Vector2Tpl ( Type  s = 0 )

inlineexplicit

Default constructor.

Inits vector to (0,0).

Parameters

s	default init value for both coordinates

Vector2Tpl() [2/2]

template<typename Type >

Vector2Tpl< Type >::Vector2Tpl ( Type  _x, Type  _y  )

inline

Constructor from a couple of coordinates.

Inits vector to (x,y).

Parameters

_x	x coordinate
_y	y coordinate

Member Function Documentation

cross()

template<typename Type >

Type Vector2Tpl< Type >::cross ( const Vector2Tpl< Type > &  v ) const

inline

Cross product.

Returns

a positive value if (u,v) makes a counter-clockwise turn, negative for clockwise turn, and zero if the vectors are parallel
