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.

Since: QGIS 3.18

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 46 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.

◆ isInFront()

bool QgsRay3D::isInFront ( const QVector3D & point ) const
