Public Functions

inline BBox(real_type xmin, real_type ymin, real_type xmax, real_type ymax, int_type id, int_type ipos)

Construct a bounding box with additional information

Parameters

  • xmin – [in] x-minimimum box coordinate

  • ymin – [in] y-minimimum box coordinate

  • xmax – [in] x-maximum box coordinate

  • ymax – [in] y-maximum box coordinate

  • id – [in] identifier of the box

  • ipos – [in] ranking position of the box

inline BBox(vector<PtrBBox> const &bboxes, int_type id, int_type ipos)

Build a buonding box that cover a list of bounding box

Parameters

  • bboxes – [in] list of bounding box

  • id – [in] identifier of the box

  • ipos – [in] ranking position of the box

inline real_type Xmin() const

x-minimum coordinate of the bbox

inline real_type Ymin() const

y-minimum coordinate of the bbox

inline real_type Xmax() const

x-maximum coordinate of the bbox

inline real_type Ymax() const

y-maximum coordinate of the bbox

inline int_type const &Id() const

return BBOX id

inline int_type const &Ipos() const

return BBOX position

inline BBox const &operator=(BBox const &rhs)

copy a bbox

inline bool collision(BBox const &box) const

detect if two bbox collide

void join(vector<PtrBBox> const &bboxes)
