This page uses the technique of ray tracing (via Povray) to plot algebraic surfaces, i.e., surfaces defined by implicit algebraic equations. This technique gives excellent results, but requires a relatively important amount of time for the computation. You are therefore asked to be patient, and not to ask for plots of too high quality (size and fluidity of animation).
