Detailed Description

2D box class.

2D box which has planes parallel to the major axes and is specified by two points (specified with 32 bits integers) on a diagonal. This class is part of the standard Open Inventor datatype classes and is used as input and output to geometry operations.

Constructor & Destructor Documentation

SbBox2i32::SbBox2i32 (  )  [inline]

Constructor for a 2D integer box.

The box is initially empty.

SbBox2i32::SbBox2i32 ( int  xmin,
int  ymin,
int  xmax,
int  ymax 
) [inline]

Constructor for a 2D integer box.

xmin , ymin , xmax , and ymax are the bounds of the box.

SbBox2i32::SbBox2i32 ( const SbVec2i32 _min,
const SbVec2i32 _max 
) [inline]

Constructor for a 2D integer box.

m_min and m_max are the corners of the diagonal that defines the box.

SbBox2i32::~SbBox2i32 (  )  [inline]

Destructor.
