Member Function Documentation

static Box kanzi::Box::fromContainedPoints ( Vector3  point1,
Vector3  point2 
)
static

Creates a box from two points.

The box will contain the given two points.

Parameters
point1First point.
point2Second point.
Returns
Box which contains both of the given points.
static Box kanzi::Box::fromCornerAndSize ( Vector3  minimumCorner,
Vector3  size 
)
static

Creates a box from a point and box size.

Parameters
minimumCornerMinimum corner point for the box.
sizeSize for the box.
Returns
Box which has a specified minimumCorner and size.
static Box kanzi::Box::fromCenterAndSize ( Vector3  center,
Vector3  size 
)
static

Creates a box from center and size.

Parameters
centerCenter for the box.
sizeSize for the box.
Returns
Box which has specified center and size.
static Box kanzi::Box::fromCorners ( Vector3  minimumCorner,
Vector3  maximumCorner 
)
static

Creates a box from minimum and maximum corners.

Parameters
minimumCornerMinimum corner for the box.
maximumCornerMaximum corner for the box.
Returns
Box which has specified minimum and maximum corners.
Box kanzi::Box::extendedBy ( Vector3  point) const
inline

Returns a box extended to include a given point.

Parameters
pointPoint to be included in the box.
Returns
Box extended with given point.
Vector3 kanzi::Box::getMinimumCorner ( ) const
inline

Gets minimum corner of box.

Returns
Minimum corner of the box.
Vector3 kanzi::Box::getMaximumCorner ( ) const
inline

Gets maximum corner of box.

Returns
Maximum corner of the box.
Vector3 kanzi::Box::getCenter ( ) const
inline

Gets center of the box.

Returns
Center of the box.
Vector3 kanzi::Box::getSize ( ) const
inline

Gets size of box.

Returns
Size of the box.
bool kanzi::Box::isEmpty ( ) const
inline

Indicates whether the box is empty.

Returns
true if box is empty, false if box is not empty.
bool kanzi::Box::isValid ( ) const
inline

Indicates whether the box is valid.

Box is valid when minimum corner is componentwise less or equal to maximum corner.

Returns
true if minimum corner is componentwise less or equal to maximum corner, otherwise false.
bool kanzi::Box::contains ( Vector3  point) const
inline

Checks if the given point is inside the box.

Note
The box is considered closed from minimum corner (left/right) but open from maximum corner (right/bottom).
Parameters
pointPoint to check to be in the box.
Returns
true if given point was in the box, otherwise false.
bool kanzi::Box::contains ( const Box volume2) const
inline

Checks if box contains other box completely.

Parameters
volume2Other box to test
Returns
true if volume2 is completely inside this box.
float kanzi::Box::getVolume ( ) const
inline

Calculates the volume of the box.

Returns
Volume of the box.
Box kanzi::Box::translatedBy ( Vector3  translation) const
inline

Translates a box.

Parameters
translationTranslation amount.
