MathMod is a powerful yet easy to use software solution that allows you to perform complex 3D and 4D surface modelling. With it you are able to generate models and visualize them in implicit or parametric form.
MathMod is a complete rewrite of K3DSurf with many new features and optimizations.
MathMod is a portable interactive plotting and graphing program for Windows, Linux, MacOSX and many other platforms.
MathMod allows to plot 3D mathematical surfaces, described by implicit or parametric equations, and offers a very large database of model samples that can be generated with it. It's Free and Open Source under the terms of the GPL licence version 2 or later.
