Detailed Description

A bounding box, given by the extreme coordinates.

Constructor & Destructor Documentation

BoundingBox() [1/2]

dialect::BoundingBox::BoundingBox ( double  x, double  X, double  y, double  Y  )

inline

Standard constructor.

Parameters

[in]	x	Lower bound on x-coordinates of the box.
[in]	X	Upper bound on x-coordinates of the box.
[in]	y	Lower bound on y-coordinates of the box.
[in]	Y	Upper bound on y-coordinates of the box.

BoundingBox() [2/2]

dialect::BoundingBox::BoundingBox ( void  )

inline

Default constructor.

Constructs a bounding box that serves as "zero" when adding boxes together. Can be thought of as the box whose interior consists solely of the point at infinity on the Riemann Sphere.

Member Function Documentation

getInterval()

interval dialect::BoundingBox::getInterval ( vpsc::Dim  dim )

inline

Get the interval in a given dimension.

Parameters

[in]

dim

The desired interval's variable dimension; thus, X if you want the box's horizontal interval, Y if you want its vertical interval.
