Detailed Description

A 3-dimensional box composed of x, y, z coordinates.

A box composed of x/y/z minimum and maximum values. It is often used to return the 3D extent of a geometry or collection of geometries.

Since

Constructor & Destructor Documentation

QgsBox3d() [1/3]

QgsBox3d::QgsBox3d	(	double	xmin = 0,
		double	ymin = 0,
		double	zmin = 0,
		double	xmax = 0,
		double	ymax = 0,
		double	zmax = 0
	)

Constructor for QgsBox3D which accepts the ranges of x/y/z coordinates.

Definition at line 21 of file qgsbox3d.cpp.

QgsBox3d() [2/3]

QgsBox3d::QgsBox3d	(	const QgsPoint &	p1,
		const QgsPoint &	p2
	)

Constructs a QgsBox3D from two points representing opposite corners of the box.

The box is normalized after construction.

Definition at line 27 of file qgsbox3d.cpp.

QgsBox3d() [3/3]

QgsBox3d::QgsBox3d

(

const QgsRectangle &

rect

)

Constructs a QgsBox3D from a rectangle.

Z Minimum and Z Maximum are set to 0.0.

Definition at line 35 of file qgsbox3d.cpp.

Member Function Documentation

contains() [1/2]

bool QgsBox3d::contains

(

const QgsBox3d &

other

)

const

Returns true when box contains other box.

Definition at line 102 of file qgsbox3d.cpp.

contains() [2/2]

bool QgsBox3d::contains

(

const QgsPoint &

point

)

const

Returns true when box contains a point.

If the point is a 2D point (no z-coordinate), then the containment test will be performed on the x/y extent of the box only.
