Library:
  surfex.lib
Purpose:
  Procedures for visualizing and rotating surfaces.
Author:
  Oliver Labs
  This library uses the program surf
  (written by Stefan Endrass and others)
  and surfex (written by Oliver Labs and others, mainly Stephan Holzer).

Note:
  It is still an alpha version (see http://www.AlgebraicSurface.net)
  This library requires the program surfex, surf and java to be installed. The software is used for producing raytraced images of surfaces. You can download `surfex` from http://www.surfex.AlgebraicSurface.net

  surfex is a front-end for surf which aims to be easier to use than the original tool.

Procedures:

> D.9.4.1 plotRotated |  | Plot the surface given by the polynomial p with the coordinates coords(list)
> D.9.4.2 plotRot |  | Similar to plotRotated, but guesses automatically which coordinates should be used
> D.9.4.3 plotRotatedList |  | Plot the varieties given by the list varieties with the coordinates coords
> D.9.4.4 plotRotatedDirect |  | Plot the varieties given by the list varietiesList
> D.9.4.5 plotRotatedListFromSpecifyList |  | Plot the varieties given by the list varietiesList
