Class: QgsBox3D¶

class qgis.core.QgsBox3D¶

Bases: sip.wrapper

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.

QgsBox3D(x: Optional[Union[QgsPoint, QgsRectangle, float]] = Py_None, y: Optional[QgsPoint, float] = Py_None, z: Optional[Union[bool, float]] = Py_None, x2: Optional[Union[bool, float]] = Py_None, y2: Optional[float] = Py_None, z2: Optional[float] = Py_None, n: Optional[bool] = Py_None) Constructor for QgsBox3D which accepts the ranges of x/y/z coordinates. If normalize is False then the normalization step will not be applied automatically.

Attributes

staticMetaObject

center(self) → QgsVector3D¶

Returns the center of the box as a vector.

New in version 3.34.

Return type:: QgsVector3D

combineWith(self, box: QgsBox3D)¶

Expands the bbox so that it covers both the original rectangle and the given rectangle.

New in version 3.34.

combineWith(self, x: float, y: float, z: float) Expands the bbox so that it covers both the original rectangle and the given point.

New in version 3.34.

Parameters:: box (QgsBox3D) –

contains(self, other: QgsBox3D) → bool¶

Returns True when box contains other box.

contains(self, point: QgsPoint) -> bool 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.

contains(self, x: float, y: float, z: float) -> bool Returns True when box contains a point (x, y, z). A point on the border of the box will also return True

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.

New in version 3.34.

Parameters:: other (QgsBox3D) –
Return type:: bool

corners(self) → List[QgsVector3D]¶

Returns an array of all box corners as 3D vectors.

Return type:: List[QgsVector3D]

depth(self) → float¶

Returns the depth of the box.

isNull(self) → bool¶

Test if the box is null (all coordinates NaN or after call to setMinimal()). A null box is also an empty box.
