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)
	Adds the vector a.

BOOL isEqual(Vec2D a)
	Returns true if this vector and vector a are equal.

Vec2D inverse()
	Returns the inverse of this vecotr.

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)
	Substracts the vector a.
