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.

Note: In QGIS 3.34 this class was renamed from QgsBox3d to QgsBox3D. The old QgsBox3d name remains available in PyQGIS for compatibility.
