How To Install surf-alggeo-nox on Ubuntu 18.04
Introduction
In this tutorial we learn how to install surf-alggeo-nox on Ubuntu 18.04.
What is surf-alggeo-nox
surf-alggeo-nox is:
Surf is a script driven tool to visualize some real algebraic geometry: plane algebraic curves, algebraic surfaces and hyperplane sections of surfaces.
The algorithms should be stable enough not to be confused by curve/surface singularities in codimension greater than one and the degree of the surface or curve. This has been achieved quite a bit. Curves of degree up to 30 and surfaces of degree up to 20 have been drawn successfully. However, there are examples of curves/surfaces of lower degree where surf fails to produce perfect images. This happens especially if the equation of the curve/surface is not reduced. Best results are achieved using reduced equations. On the other hand, surf displays the Fermat-curves accurately for degree up to 98.
Surf is free software distributed under the GNU General Public License (GPL).
This package provides the script driven tool surf without X support.
