Methods

o raytrace 
  public void raytrace(IntersectionRay ray,
                       Color color)
Trace the ray, checking for intersection with each object in the world. If there is an intersection, compute the color at the point of intersection, otherwise return black. The color is returned via the color reference parameter. This method can only be called recursively a maximum of MAX_DEPTH times for any instance of a World object.
