Class: QgsVector3D¶

class qgis.core.QgsVector3D¶

Bases: sip.wrapper

Constructs a null vector

QgsVector3D(x: float, y: float, z: float) Constructs a vector from given coordinates

QgsVector3D(v: QVector3D) Constructs a vector from single-precision QVector3D

QgsVector3D(QgsVector3D)

Class for storage of 3D vectors similar to QVector3D, with the difference that it uses double precision instead of single precision floating point numbers.

New in version 3.0: Enums
