The solutions presented are effective techniques for people who need proper visualizations in the real world. For example, flight simulators must render the objects on the screen (in all parts of the screen including the sides), without distortion, in order to be effective training tools. Curved displays, ray casting, and rendering w/ piecewise linear projection planes are all techniques are all methods used in practice to actually help flight simulators ensure effectiveness.
