Function Documentation

bbox_area()

Real geo::bbox_area ( const Bbox_2 & box )

inline

bbox_diameter()

Real geo::bbox_diameter ( const Bbox_2 & box )

inline

closest_on()

Point_2 geo::closest_on ( const Segment_2 & s, const Point_2 & o )

inline

cosine()

Real geo::cosine ( const Vector_2 & v1, const Vector_2 & v2 )

inline

Compute the cosine of the angle between two 2D vectors.

cropBox()

Bbox_2 geo::cropBox ( const Bbox_2 & box, const Bbox_2 & crop )

inline

distance45()

float geo::distance45 ( const Point_2 & A, const Point_2 & B )

inline

Compute the 45-degree or "Queen's" distance between 2 points. This is analogous to the Manhattan distance but with 45° rather than 90° steps.

expandBox()

Bbox_2 geo::expandBox ( const Bbox_2 & box, Real m )

inline

expandBox_r()

Bbox_2 geo::expandBox_r ( const Bbox_2 & box, Real m_rel )

inline

to_string()

std::string geo::to_string ( const Bbox_2 & box )

inline
