Detailed Description

The SbBox2s class is a 2 dimensional box with short integer coordinates.

This box class is used by other classes in Coin for data exchange. It provides storage for two box corners with short integer coordinates, which is among other things useful for representing screen or canvas areas in absolute window coordinates.

Constructor & Destructor Documentation

SbBox2s::SbBox2s ( void  )
inline

The default constructor makes an empty box.

SbBox2s::SbBox2s ( short  xmin,
short  ymin,
short  xmax,
short  ymax 
)
inline

Constructs a box with the given corner coordinates.

xmin should be less than xmax and ymin should be less than ymax if you want to make a valid box.

SbBox2s::SbBox2s ( const SbVec2s boxmin,
const SbVec2s boxmax 
)
inline

Constructs a box with the given corners.

The coordinates of min should be less than the coordinates of max if you want to make a valid box.

Member Function Documentation

SbBox2s & SbBox2s::setBounds ( short  xmin,
short  ymin,
short  xmax,
short  ymax 
)
inline

Reset the boundaries of the box.

xmin should be less than xmax and ymin should be less than ymax if you want to make a valid box.

Returns reference to self.

See also
getBounds().
SbBox2s & SbBox2s::setBounds ( const SbVec2s boxmin,
const SbVec2s boxmax 
)
inline

Reset the boundaries of the box with the given corners.

The coordinates of min should be less than the coordinates of max if you want to make a valid box.

Returns reference to self.

See also
getBounds().
SbBox2s & SbBox2s::setBounds ( const SbBox2i32 &  box)

Reset the boundaries with the boundaries of the given box.

Returns reference to self.

See also
setBounds()
SbBox2s & SbBox2s::setBounds ( const SbBox2f box)

Reset the boundaries with the boundaries of the given box.

Returns reference to self.

See also
setBounds()
SbBox2s & SbBox2s::setBounds ( const SbBox2d box)

Reset the boundaries with the boundaries of the given box.

Returns reference to self.

See also
setBounds()
void SbBox2s::getBounds ( short &  xmin,
short &  ymin,
short &  xmax,
short &  ymax 
) const
inline

Returns the box boundary coordinates.

See also
setBounds(), getMin(), getMax().
void SbBox2s::getBounds ( SbVec2s boxmin,
SbVec2s boxmax 
) const
inline

Returns the box corner points.

See also
setBounds(), getMin(), getMax().
const SbVec2s & SbBox2s::getMin ( void  ) const
inline

Returns the minimum point. This should usually be the lower left corner point of the box.

See also
getOrigin(), getMax().
const SbVec2s & SbBox2s::getMax ( void  ) const
inline

Returns the maximum point. This should usually be the upper right corner point of the box.

See also
getMin().
void SbBox2s::extendBy ( const SbVec2s point)

Extend the boundaries of the box by the given point, i.e. make the point fit inside the box if it isn't already within it.

void SbBox2s::extendBy ( const SbBox2s box)

Extend the boundaries of the box by the given box parameter. This is equal to calling extendBy() twice with the corner points.

void SbBox2s::makeEmpty ( void  )

Marks this as an empty box.

See also
isEmpty().
SbBool SbBox2s::intersect ( const SbVec2s point) const

Check if the given point lies within the boundaries of this box.

SbBool SbBox2s::intersect ( const SbBox2s box) const

Check if box lies wholly or partly within the boundaries of this box.

void SbBox2s::getOrigin ( short &  originX,
short &  originY 
) const
inline

Returns the coordinates of the box origin (i.e. the lower left corner).

See also
getMin().
void SbBox2s::getSize ( short &  sizeX,
short &  sizeY 
) const
inline

Returns width and height of box.

float SbBox2s::getAspectRatio ( void  ) const
inline

Returns aspect ratio of box, which is defined as box width divided on box height.
