Constructor & Destructor Documentation

QgsAABB() [1/2]

QgsAABB::QgsAABB ( )

default

Constructs bounding box with null coordinates.

QgsAABB() [2/2]

QgsAABB::QgsAABB	(	float	xMin,
		float	yMin,
		float	zMin,
		float	xMax,
		float	yMax,
		float	zMax
	)

Constructs bounding box.

Member Function Documentation

center()

QVector3D QgsAABB::center ( ) const

inline

Returns coordinates of the center of the box.

Definition at line 68 of file qgsaabb.h.

distanceFromPoint() [1/2]

float QgsAABB::distanceFromPoint	(	float	x,
		float	y,
		float	z
	)		const

Returns shortest distance from the box to a point.

Definition at line 46 of file qgsaabb.cpp.

distanceFromPoint() [2/2]

float QgsAABB::distanceFromPoint

(

QVector3D

v

)

const

Returns shortest distance from the box to a point.

Definition at line 54 of file qgsaabb.cpp.

fromBox3D()

static QgsAABB QgsAABB::fromBox3D ( const QgsBox3D &  box3D, const QgsVector3D &  origin  )

Constructs bounding box from QgsBox3D by subtracting origin 3D vector.

Note: this is potentially lossy operation as the coordinates are converted from double values to floats!
