Public Types
enum	STATE { BAD_POINT = 0, GOOD_POINT = 1 }
enum	COORD_INDEX { X = 0, Y = 1, Z = 2, W = 3 }
	can be used to safely access coordinates
Public Member Functions
	Point3D (const Point3D &)
	Copy constructor.
	Point3D (double x, double y, double z, double w=1)
	constructor with given coordinates
Point3D &	operator= (const Point3D &)
	implement = operator
bool	isGoodPoint ()
	Decides wether the point is good or bad depending on its state.
double	x () const
double	y () const
double	z () const
double	w () const
double &	operator() (int index)
	return the coordinate value
double &	operator[] (int index)
	return the coordinate value
void	setCoord (double x, double y, double z, double w=1)
	setter
jblas::vec4 &	getCoord ()
	Return a vector containing the coordinates.
virtual void	clear ()
	set the point at the origin (0,0,0,1)
Public Attributes
jblas::vec4	coord
	this vector contains the coordinates of the point (X,Y,Z,W)
Point3D::STATE	state
	can tel if this point is a "good" one or a "bad" one for example a bad point can be a result of an Outer measure
