Constructor & Destructor Documentation

DedxLine ( )

inline

A line is definied either by a point and a slope, or by endpoints.

If a single point is given, both endpoints are given by the same point (length = 0). Default constructor

Definition at line 92 of file LineHelper.h.

92 : m_m(0), m_vertical(false) {}

int m_vertical

If the line is vertical, this is set to true.

Definition: LineHelper.h:177

double m_m

Slope of the line.
