	Returns the angle between the ray and the vector from the ray's origin and the point point.

Detailed Description

A representation of a ray in 3D.

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

Member Function Documentation

angleToPoint()

double QgsRay3D::angleToPoint

(

const QVector3D &

point

)

const

Returns the angle between the ray and the vector from the ray's origin and the point point.

Definition at line 57 of file qgsray3d.cpp.

direction()

QVector3D QgsRay3D::direction ( ) const

inline

Returns the direction of the ray see setDirection().

Definition at line 50 of file qgsray3d.h.

directionInversed()

QVector3D QgsRay3D::directionInversed ( ) const
