Class: 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.

Added in version 3.18.

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

class qgis.core.QgsRay3D[source]¶

Bases: object

__init__(origin: QVector3D, direction: QVector3D)

Constructor

Note

: the direction is automatically normalized

Parameters:

__init__(a0: QgsRay3D)

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

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

direction(self) → QVector3D[source]¶

Returns the direction of the ray see setDirection()

isInFront(self, point: QVector3D) → bool[source]¶

Checks whether the point is in front of the ray

origin(self) → QVector3D[source]¶

Returns the origin of the ray
