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 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

Checks whether the point is in front of the ray.

Definition at line 41 of file qgsray3d.cpp.

◆ origin()

QVector3D QgsRay3D::origin ( ) const
inline

Returns the origin of the ray.

Definition at line 36 of file qgsray3d.cpp.

◆ setDirection()

void QgsRay3D::setDirection ( const QVector3D  direction)

Sets the direction of the ray.
