List of all members.

Public Member Functions
	Ray (const Point &origin, const Vector &direction, const float start=RAY_EPSILON, const float end=HUGE_VAL, unsigned int _id=-1)
	constructeur (origine, direction). direction est un vecteur unitaire.
	Ray (const Point &origin, const Point &destination, const float start=RAY_EPSILON, const float end=1.f-RAY_EPSILON, unsigned int _id=-1)
	constructeur (origine, destination).
bool	isBackward (const int axis) const
	renvoie vrai si la direction du rayon est < 0 pour l'axe 'axis'.
Point	operator() (const float t) const
	construit le point a l'abscisse 't'.
Public Attributes
