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.

Methods

Returns the cross product of two vectors

distance

Returns the distance with the other QgsVector3

dotProduct

Returns the dot product of two vectors

isNull

Returns True if all three coordinates are zero

length

normalize

Normalizes the current vector in place.

perpendicularPoint

Returns the perpendicular point of vector vp from [v1 - v2]

set

Sets vector coordinates

toString

Returns a string representation of the 3D vector.
