# What is Pisces?

Pisces is a Platform for Implicit Surfaces and Curves and the
Exploration of Singularities. Each term in the
acronym has meaning, but, in a nutshell, Pisces is a project that
attempts to supply the mathematical and scientific communities with
numerical tools to compute and visualize curves and surfaces that are
defined *implicitly*. For a simple example, note that the
equation to *x^2+y^2=1* is satisfied by the set of points on in
the plane that lie on the unit circle, so that the equation implicitly
defines the unit circle. One product of the Pisces
project is a software package that provides a variety of
state-of-the-art algorithms for computing implicitly-defined curves
and surfaces. This software is under development.
