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. More...

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.
SbBox3s::SbBox3s | ( | void | ) |
The default constructor makes an empty box.
References makeEmpty().
SbBox3s::SbBox3s | ( | short | xmin, |
short | ymin, | ||
short | zmin, | ||
short | xmax, | ||
short | ymax, | ||
short | zmax | ||
) |
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.
References setBounds().
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.
References setBounds().
SbBox3s::SbBox3s | ( | const SbBox3i32 & | box | ) | [inline, explicit] |
Constructs a box with coordinates from box, converting the coordinates to short integers
SbBox3s::SbBox3s | ( | const SbBox3f & | box | ) | [inline, explicit] |
Constructs a box with coordinates from box, converting the coordinates to short integers
SbBox3s::SbBox3s | ( | const SbBox3d & | box | ) | [inline, explicit] |
Constructs a box with coordinates from box, converting the coordinates to short integers
SbBox3s::~SbBox3s | ( | void | ) |
Destructor does nothing.
void SbBox3s::setBounds | ( | short | xmin, |
short | ymin, | ||
short | zmin, | ||
short | xmax, | ||
short | ymax, | ||
short | zmax | ||
) |
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.
References SoDebugError::postWarning(), and SbVec3s::setValue().
Referenced by SbBox3s().
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.
References SoDebugError::postWarning().
Reset the boundaries to the boundaries of the given box.
Returns reference to self.
References SbBox3i32::getMax(), SbBox3i32::getMin(), SbBox3i32::isEmpty(), makeEmpty(), and SbVec3s::setValue().
Reset the boundaries to the boundaries of the given box.
Returns reference to self.
References SbBox3f::getMax(), SbBox3f::getMin(), SbBox3f::isEmpty(), makeEmpty(), and SbVec3s::setValue().
Reset the boundaries to the boundaries of the given box.
Returns reference to self.
References SbBox3d::getMax(), SbBox3d::getMin(), SbBox3d::isEmpty(), makeEmpty(), and SbVec3s::setValue().
const SbVec3s & SbBox3s::getMin | ( | void | ) | const |
Returns the minimum point. This should usually be the lower left corner point of the box.

SbVec3s & SbBox3s::getMin | ( | void | ) | [inline] |
Returns the minimum point. This should usually be the lower left corner point of the box.
const SbVec3s & SbBox3s::getMax | ( | void | ) | const |
Returns the maximum point. This should usually be the upper right corner point of the box.

SbVec3s & SbBox3s::getMax | ( | void | ) | [inline] |
Returns the maximum point. This should usually be the upper right corner point of the box.
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.
References SbVec3s::setValue().
Referenced by extendBy().
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.

Check if the box has been correctly specified and by that virtue has volume.
int SbBox3s::getVolume | ( | void | ) | const [inline] |

SbBool SbBox3s::intersect | ( | const SbVec3s & | point | ) | const |
Check if the given point lies within the boundaries of this box.
