There is a new method of rendering that was recently developed. It is called radiosity. It does something all the other rendering methods don't do: it figures out the relationship in the scene of all the objects present. For example, in real life, if you take a bright colored ball and put it into a white room, the walls of the room are going to reflect a little bit of color from the ball, making them look a little reddish for example. This is not possible in raytracing, since it does not bounce rays off of matte objects, such as a wall. You can compare the above.
