Vec2D Object

The Vec2D objects represents a two dimensional vector. It's normally used for UV coords.

Properties
Number x,y
Number u,v


Constructor

Vec2D( Number x, Number y)
Creates a two dimensional vector.


Methods

Vec2D add(Vec2D a)

Returns true if this vector and vector a are equal.


Vec2D inverse(Vec2D a)
Returns the inverse of vecotr a.


Vec2D multiply(Number a)
Vec2D multiply(Vec2D a)
Multiplys the vector with a.


Number norm()
Returns the vector norm of the x and y components.


Vec2D copy()
Creates a copy of the vector.


void set( Number x, Number y)
Sets the values of the vector all at once.


Vec2D sub(Vec2D)
