Constructor & Destructor Documentation

Bbox3() [1/2]

FADE3D::Bbox3::Bbox3 ( )

inline

Constructor. The bounds of the bounding box are initialized to -DBL_MAX and +DBL_MAX values. The bounding box becomes valid as soon as points are added.

Bbox3() [2/2]

FADE3D::Bbox3::Bbox3 ( const std::vector< Point3 > &  vPoints )

inlineexplicit

This constructor computes the axis aligned minimal bounding box of the points in vPoints

Member Function Documentation

add() [1/2]

bool FADE3D::Bbox3::add ( const std::vector< Point3 > &  vPoints )

inline

Add vPoints to the bounding box.

Returns

true if the bounds of the present Bbox3 have changed

false otherwise

add() [2/2]

bool FADE3D::Bbox3::add ( const Point3 &  p )

inline

Add p to the bounding box

Returns

true if the bounds of the present Bbox3 have changed

false otherwise

getMaxCoord()

double FADE3D::Bbox3::getMaxCoord ( )

inline

Returns

the maximum of (maxX,maxY,maxZ)

getMaxPoint()

Point3 FADE3D::Bbox3::getMaxPoint ( )

inline

Returns

the point with the largest coordinates of the bounding box

getMaxRange()

double FADE3D::Bbox3::getMaxRange ( ) const

inline

Returns

the maximum of rangeX,rangeY and rangeZ

getMaxX()

double FADE3D::Bbox3::getMaxX ( ) const

inline

getMaxY()

double FADE3D::Bbox3::getMaxY ( ) const

inline

getMaxZ()

double FADE3D::Bbox3::getMaxZ ( ) const

inline

getMinCoord()

double FADE3D::Bbox3::getMinCoord ( )

inline

Returns

the minimum of (minX,minY,minZ)

getMinPoint()

Point3 FADE3D::Bbox3::getMinPoint ( )

inline

Returns

the point with the smallest coordinates of the bounding box

getMinX()

double FADE3D::Bbox3::getMinX ( ) const

inline

getMinY()

double FADE3D::Bbox3::getMinY ( ) const

inline

getMinZ()

double FADE3D::Bbox3::getMinZ ( ) const

inline

getRangeX()

double FADE3D::Bbox3::getRangeX ( ) const

inline

Returns

the x-range maxX-minX

getRangeY()

double FADE3D::Bbox3::getRangeY ( ) const

inline

Returns

the y-range maxY-minY

getRangeZ()

double FADE3D::Bbox3::getRangeZ ( ) const

inline

Returns

the z-range maxZ-minZ

isValid()

bool FADE3D::Bbox3::isValid ( )

inline

Check if the bounding box has valid bounds. After construction the bounds are initialized to DBL_MAX and DBL_MIN. As soon as the first point is added Bbox3 becomes valid.

operator+()

Bbox3 FADE3D::Bbox3::operator+ ( Bbox3 &  b )

inline

Add another Bbox3 to the present one.

Returns

the axis aligned minimal bounding box of the union of the two boxes.
