surf: Visualization of algebraic curves, algebraic surfaces and hyperplane sections of surfaces#
surf is a tool to visualize some real algebraic geometry: plane algebraic curves, algebraic surfaces and hyperplane sections of surfaces. surf is script driven and has (optionally) a nifty GUI using the Gtk widget set.
This is used by the Singular Jupyter kernel to produce 3D plots.
GPL version 2 or later

GNU flex Version 2.5 or higher
GTK+ Version 1.2.0 or higher (optional)
GNU MP(gmp) Version 2 or higher
This package is “experimental” because not all of these dependencies are packaged with Sage.
Equivalent System Packages#
$ sudo zypper install surf
However, these system packages will not be used for building Sage because spkg-configure.m4 has not been written for this package; see github issue #27330
