SurgSim::Blocks::KnotIdentificationBehavior::Crossing Struct Reference

struct to store a Crossing. More...

#include <KnotIdentificationBehavior.h>

Public Member Functions
	Crossing (int id, size_t segmentId, double segmentLocation, int sign)
bool	operator== (const Crossing &rhs) const

Public Attributes
int	id
	The gauss code. abs(id) indicates which crossing. sign(id) is positive for over and negative for under.
size_t	segmentId
double	segmentLocation
int	sign
	also known as handedness. See documentation for addKnownKnotCode.

Detailed Description

struct to store a Crossing.

Gauss code is not sufficient, also need the crossing sign (aka enhanced gauss code), see: Ellis, Graham, and Cedric Fragnaud. "Computing with knot quandles." Journal of Knot Theory and Its Ramifications 27.14 (2018): 1850074.
