Public Member Functions

• BoundingBox ()

  Default constructor, initializes the bounding box to be placed at (0,0,0) with size zero.
  

• BoundingBox (const point_t &minCoord, const point_t &maxCoord)

  Initialize a bounding box from two corner points.
  

• tvector_t diagonal () const

  Compute the diagonal vector, max - min.
  

• void embrace (const point_t &crd)

  Expand the bounding box range to encompass the given coordinate.
  

• bool empty () const
• point_t getLocation (double x, double y, double z) const

  Compute a point relative to the given bounding box, the coordinates are in values 0.0 to 1.0 for points within the box.
  

• point_t getLocation11 (double x, double y, double z) const

  Compute a point relative to the given bounding box, the coordinates are in values -1.0 to 1.0 for points within the box.
  

• void insert (const BoundingBox &BB)

  Expand the bounding box range to encompass the given bounding box.
  

• bool inside (const point_t &p) const

  Check whether a specific point resides within the bounding box.
  

• const point_t & maxcoord () const

  The maximal coordinate, upper right back corner.
  

• const point_t & mincoord () const

  The minimal coordinate, lower left front corner.
  

• void setMinMax (const point_t &minCoord, const point_t &maxCoord)

  Overwrite the current values and set new ones. Updates the bounding ball automaticall.
  

• void speak (const char *context="") const
• void updateBall ()

  Compute the bounding sphere parameters of the base class.

Detailed Description

A coordinate-parallel bounding box in three dimensions.

Bounding boxes are derived from bounding balls, which may be used as base classes providing simpler, and more symmetric information. Consequently, any time a bounding box is updated, also the bounding ball information needs to be updated, because such is not computed on demand for performance reasons. Do so by explictely calling updateBall() after a set of points as been included in the bounding box.

Constructor & Destructor Documentation

BoundingBox::BoundingBox

(

)

Default constructor, initializes the bounding box to be placed at (0,0,0) with size zero.

The empty() member function will return true, like in any case of a bounding box having volume zero.

Member Function Documentation

void Eagle::BoundingBox::embrace

(

const point_t &

crd

)

[inline]

Expand the bounding box range to encompass the given coordinate.

Need to call updateBall() afterwards.

void Eagle::BoundingBox::insert

(

const BoundingBox &

BB

)

[inline]

Expand the bounding box range to encompass the given bounding box.

Need to call updateBall() afterwards.
