Constructor & Destructor Documentation

kanzi::Box::Box ( )

inlineexplicit

Constructs an empty box.

Note: The box will contain (0, 0, 0).

kanzi::Box::Box ( Vector3 point )

inlineexplicit

Constructs a box which contains a single point.

Parameters

point Point for box to contain.

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

point1	First point.
point2	Second 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

minimumCorner	Minimum corner point for the box.
size	Size 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

center	Center for the box.
size	Size 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

minimumCorner	Minimum corner for the box.
maximumCorner	Maximum 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

point Point 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

point Point 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

volume2 Other 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

translation Translation amount.
