Detailed Description

The SbBox3s class is a 3 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

SbBox3s::SbBox3s (void) [inline]

The default constructor makes an empty box.

SbBox3s::SbBox3s (shortxmin, shortymin, shortzmin, shortxmax, shortymax, shortzmax) [inline]

Constructs a box with the given corner coordinates.

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

SbBox3s::SbBox3s (const SbVec3s &minvec, const SbVec3s &maxvec) [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

SbBox3s & SbBox3s::setBounds (shortxmin, shortymin, shortzmin, shortxmax, shortymax, shortzmax) [inline]

Reset the boundaries of the box.

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

Returns reference to self.

See also:

getBounds().

SbBox3s & SbBox3s::setBounds (const SbVec3s &minvec, const SbVec3s &maxvec) [inline]

Reset the boundaries of the box with the given corners.

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

Returns reference to self.

See also:

getBounds().

SbBox3s & SbBox3s::setBounds (const SbBox3i32 &box)

Reset the boundaries to the boundaries of the given box.

Returns reference to self.

See also:

getBounds().

SbBox3s & SbBox3s::setBounds (const SbBox3f &box)

Reset the boundaries to the boundaries of the given box.

Returns reference to self.

See also:

getBounds().

SbBox3s & SbBox3s::setBounds (const SbBox3d &box)

Reset the boundaries to the boundaries of the given box.

Returns reference to self.

See also:

getBounds().

void SbBox3s::getBounds (short &xmin, short &ymin, short &zmin, short &xmax, short &ymax, short &zmax) const [inline]

Returns the box boundary coordinates.

See also:

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

void SbBox3s::getBounds (SbVec3s &minvec, SbVec3s &maxvec) const [inline]

Returns the box corner points.

See also:

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

const SbVec3s & SbBox3s::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 SbVec3s & SbBox3s::getMax (void) const [inline]

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

See also:

getMin().

void SbBox3s::extendBy (const SbVec3s &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 SbBox3s::extendBy (const SbBox3s &box)

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

void SbBox3s::makeEmpty (void)

Marks this as an empty box.

See also:

isEmpty().

SbBool SbBox3s::intersect (const SbVec3s &point) const

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

SbBool SbBox3s::intersect (const SbBox3s &box) const

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

void SbBox3s::getOrigin (short &originX, short &originY, short &originZ) const [inline]

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

See also:

getMin().

void SbBox3s::getSize (short &sizeX, short &sizeY, short &sizeZ) const [inline]

Returns width and height of box.
