Classes
struct	Enki::Vector
	A vector in a 2D space. More...
struct	Enki::Matrix22
	A 2x2 matrix. More...
struct	Enki::Segment
	A segment in a 2D space, basically two points. More...
struct	Enki::Polygone
	Polygone, which is a vector of points. Anti-clockwise, standard trigonometric orientation. More...

Namespaces
	Enki
	Enki is the namespace of the Enki simulator. All Enki functions and classes excepted the math one are inside this namespace.

Typedefs
typedef Vector	Enki::Point
	A point in a 2D space, another name for a vector. More...

Functions
std::ostream &	Enki::operator<< (std::ostream &outs, const Vector &vector)
	Print a vector to a stream.
std::ostream &	Enki::operator<< (std::ostream &outs, const Polygone &polygone)
	Print a polygone to a stream. More...
double	Enki::normalizeAngle (double angle)
	Normlize an angle to be between -PI and +PI. More...
Point	Enki::getIntersection (const Segment &s1, const Segment &s2)
	get the intersection point between two line segments returns Point(HUGE_VAL, HUGE_VAL) if there's no intersection added by yvan..nosp@m.bour.nosp@m.quin@.nosp@m.epfl.nosp@m..ch More...
double	Enki::getTriangleAreaTwice (const Point &a, const Point &b, const Point &c)
	Returns 2 times the signed triangle area. More...
double	Enki::getTriangleHeight (const Point &a, const Point &b, const Point &c)
	Returns signed height of triangle abc with base ab. More...
