Vector2D

Represents a two-dimensional relative coordinates.

struct Vector2D
{
	Vector2D();
	Vector2D( atl::real x, atl::real y );
	Vector2D( Point2D from, Point2D to);

	atl::real deltaX;
	atl::real deltaY;

	atl::real DeltaX( void ) const;
	atl::real DeltaY( void ) const;

	bool operator == ( const Vector2D& rhs ) const;
	bool operator != ( const Vector2D& rhs ) const;

	Vector2D operator - () const;
};

Structure fields and default values (if defined) are described below:

• Real DeltaX
• Real DeltaY

struct Vector2D
{
	Real	DeltaX;
	Real	DeltaY;


	Real DeltaX( void ) const	{ return DeltaX;	};
	Real DeltaY( void ) const	{ return DeltaY;	};

	bool operator == ( const avl::Vector2D& rhs ) const
	{
		return DeltaX == rhs.DeltaX && 
			DeltaY == rhs.DeltaY;
	}

	bool operator != ( const avl::Vector2D& rhs ) const
	{
		return !(operator==(rhs));
	}
