Description: visualization of real algebraic geometry -- no X support
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.

This package provides the script driven tool surf without X support.
