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() [1/6]

SbBox2s::SbBox2s ( void )

inline

The default constructor makes an empty box.

SbBox2s() [2/6]

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() [3/6]

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.

SbBox2s() [4/6]

SbBox2s::SbBox2s ( const SbBox2i32 & box )

inlineexplicit

Constructs an SbBox2s instance from the value in an SbBox2i32 instance.

Since

Coin 2.5

SbBox2s() [5/6]

SbBox2s::SbBox2s ( const SbBox2f & box )

inlineexplicit

Constructs an SbBox2s instance from the value in an SbBox2f instance.

Since

Coin 2.5

SbBox2s() [6/6]

SbBox2s::SbBox2s ( const SbBox2d & box )

inlineexplicit

Constructs an SbBox2s instance from the value in an SbBox2d instance.

Since

Coin 2.5

Member Function Documentation

extendBy() [1/2]

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.

extendBy() [2/2]

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.

getAspectRatio()

float SbBox2s::getAspectRatio ( void ) const

inline

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

getBounds() [1/2]

void SbBox2s::getBounds ( SbVec2s & boxmin, SbVec2s & boxmax ) const

inline

Returns the box corner points.

See also

setBounds(), getMin(), getMax().

getBounds() [2/2]

void SbBox2s::getBounds ( short & xmin, short & ymin, short & xmax, short & ymax ) const

inline

Returns the box boundary coordinates.

See also

setBounds(), getMin(), getMax().

getCenter()

SbVec2s SbBox2s::getCenter ( void ) const

inline

Returns the center point of the box.

getMax() [1/2]

SbVec2s & SbBox2s::getMax ( void )

inline

Returns the upper right corner of the box.

See also

getMin().

getMax() [2/2]

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().

getMin() [1/2]

SbVec2s & SbBox2s::getMin ( void )

inline

Returns the lower left corner of the box.

See also

getOrigin(), getMax().

getMin() [2/2]

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().

getOrigin()

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().

getSize() [1/2]

void SbBox2s::getSize ( short & sizeX, short & sizeY ) const

inline

Returns width and height of box.

getSize() [2/2]

SbVec2s SbBox2s::getSize ( void ) const

inline

Returns width and height of box as a 2D vector.

Since

Coin 3.0

hasArea()

SbBool SbBox2s::hasArea ( void ) const

inline

Check if the box has been correctly specified and by that virtue has "positive" area, i.e. all coordinates of its upper right corner (the maximum point) are greater than the corresponding coordinates of its lower left corner (the minimum point).

intersect() [1/2]

SbBool SbBox2s::intersect

(

const SbBox2s &

box

)

const

Check if box lies entirely or partially within the boundaries of this box.

intersect() [2/2]

SbBool SbBox2s::intersect

(

const SbVec2s &

point

)

const

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

isEmpty()

SbBool SbBox2s::isEmpty ( void ) const

inline

Check if this has been marked as an empty box.

See also

makeEmpty().

makeEmpty()

void SbBox2s::makeEmpty

(

void

)

Marks this as an empty box.

See also

isEmpty().

setBounds() [1/5]

SbBox2s & SbBox2s::setBounds

(

const SbBox2d &

box

)

Reset the boundaries with the boundaries of the given box.

Returns reference to self.
