Member Function Documentation

Ray3D Ray3D::add (  const Point3D &  p  )  const

This method computes the translation of the ray by p and returns the translated ray.

Point3D Ray3D::operator() (  double  t  )  const

This method returns the point at a distance of t along the ray.

Ray3D Ray3D::operator+ (  const Point3D &  p  )  const

This method computes the translation of the ray by p and returns the translated ray.

Ray3D & Ray3D::operator+= (  const Point3D &  p  )

This method translates the current ray by p.

Ray3D Ray3D::operator- (  const Point3D &  p  )  const

This method computes the translation of the ray by -p and returns the translated ray.

Ray3D & Ray3D::operator-= (  const Point3D &  p  )

This method translates the current ray by -p.

Ray3D Ray3D::subtract (  const Point3D &  p  )  const

This method computes the translation of the ray by -p and returns the translated ray.
