Although Pisces can compute implicitly-defined curves in arbitrary dimension and can also compute some implicitly-defined surfaces, this demonstration is restricted to the case of planar curves (that is, zero sets of two-variable functions) in order to simplify the user-interface to Pisces.

Furthermore, Pisces contains five different algorithms that can compute planar level sets, and the user can fully control the way that each algorithm works. In this demonstration, however, we only allow the user to choose from one of two algorithms, and we do not allow the user to alter the parameters for that algorithm.

If you like what you see, you may want to download Pisces and install it on your own computer network.
