QgsRay3D(QgsRay3D)

A representation of a ray in 3D.

A ray is composed of an origin point (the start of the ray) and a direction vector.

Methods

angleToPoint

Returns the angle between the ray and the vector from the ray’s origin and the point point

direction

Returns the direction of the ray see setDirection()

isInFront

Checks whether the point is in front of the ray

origin

Returns the origin of the ray

projectedPoint

Returns the projection of the point on the ray (which is the closest point of the ray to point)

setDirection

Sets the direction of the ray

setOrigin

Sets the origin of the ray

angleToPoint(self, point: QVector3D)float

Returns the angle between the ray and the vector from the ray’s origin and the point point

Parameters

point (QVector3D) –

Return type

float

direction(self)QVector3D

Returns the direction of the ray see setDirection()

Return type

QVector3D

isInFront(self, point: QVector3D)bool

Checks whether the point is in front of the ray

Parameters

point (QVector3D) –

Return type

bool

origin(self)QVector3D

Returns the origin of the ray
