Class: QgsBox3D¶

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.

class qgis.core.QgsBox3D[source]¶

Bases: object

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.

Parameters:

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)

center(self) → QgsVector3D[source]¶

Returns the center of the box as a vector.

Added in version 3.34.

Return type:: QgsVector3D

combineWith(self, box: QgsBox3D)[source]¶

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

Added in version 3.34.

Parameters:: box (QgsBox3D)

combineWith(self, x: float, y: float, z: float)[source]

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

Added in version 3.34.

Parameters:

x (float)
y (float)
z (float)

contains(self, other: QgsBox3D) → bool[source]¶

Returns True when box contains other box.

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

contains(self, point: QgsPoint) → bool[source]

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.

Parameters:: point (QgsPoint)
Return type:: bool

contains(self, x: float, y: float, z: float) → bool[source]

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.

Added in version 3.34.

Parameters:

x (float)
y (float)
z (float)

Return type:

bool

corners(self) → List[QgsVector3D]¶

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

Return type:: List[QgsVector3D]

depth(self) → float[source]¶

Returns the depth of the box.

distanceTo(self, point: QVector3D) → float[source]¶

Returns the smallest distance between the box and the point point (returns 0 if the point is inside the box)
