Constructor & Destructor Documentation

  SbBox3s::SbBox3s (void) [inline]
The default constructor makes an empty box.

  SbBox3s::SbBox3s (short xmin, short ymin, short zmin, short xmax, short ymax, short zmax) [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.

  SbBox3s::SbBox3s (const SbBox3i32 & box) [inline], [explicit]
Constructs an SbBox3s instance from the value in an SbBox3i32 instance.

  SbBox3s::SbBox3s (const SbBox3f & box) [inline], [explicit]
Constructs an SbBox3s instance from the value in an SbBox3f instance.

  SbBox3s::SbBox3s (const SbBox3d & box) [inline], [explicit]
Constructs an SbBox3s instance from the value in an SbBox3d instance.

Member Function Documentation

  SbBox3s & SbBox3s::setBounds (short xmin, short ymin, short zmin, short xmax, short ymax, short zmax) [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().

  SbVec3s & SbBox3s::getMin (void) [inline]
Returns a modifiable reference to the minimum point.

  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().

  SbVec3s & SbBox3s::getMax (void) [inline]
Returns a modifiable reference to the maximum point.

  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::isEmpty (void) const [inline]
Check if this has been marked as an empty box.

See also
    makeEmpty().

  SbBool SbBox3s::hasVolume (void) const [inline]
Check if the box has been correctly specified and by that virtue has 'positive' volume, 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).

  int SbBox3s::getVolume (void) const [inline]
Returns the volume of the box.

  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 entirely or partially within the boundaries of this box.

  SbVec3f SbBox3s::getClosestPoint (const SbVec3f & point) const
Return the point on the box closest to the given point. If the given point equals the center, the center point of the positive Z face is returned.

  SbVec3s SbBox3s::getCenter (void) const [inline]
Returns the center point of the 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.

  SbVec3s SbBox3s::getSize (void) const [inline]
Returns width, height and depth of box as a 3D vector.
