QgsRay3D (const QVector3D &origin, const QVector3D &direction)  
Constructor.  
double  angleToPoint (const QVector3D &point) const 
Returns the angle between the ray and the vector from the ray's origin and the point point.  
QVector3D  direction () const 
Returns the direction of the ray see setDirection()  
bool  isInFront (const QVector3D &point) const 
Checks whether the point is in front of the ray.  
QVector3D  origin () const 
Returns the origin of the ray.  
QVector3D  projectedPoint (const QVector3D &point) const 
Returns the projection of the point on the ray (which is the closest point of the ray to point)  
void  setDirection (const QVector3D direction) 
Sets the direction of the ray.  
void  setOrigin (const QVector3D &origin) 
Sets the origin of the ray.  
A representation of a ray in 3D.
A ray is composed of an origin point (the start of the ray) and a direction vector.
