Description:

    GANITH is an algebraic geometry toolkit, for the computation 
    and visualization of solutions to systems of algebraic equations.
    Example applications of this for geometric modeling and
    computer graphics are algebraic curve and surface
    display, curve-curve intersections, surface-surface 
    intersections, global and local parameterizations, implicitization.
    GANITH also incorporates techniques for interpolation and 
    least-squares approximation (multivariate data fitting)
    with algebraic curves and surfaces. 
    The GANITH algebraic geometry toolkit manipulates
    arbitrary degree polynomials and power series.e
    It can be used to solve a system of algebraic equations 
    Power series manipulations are used to generate piecewise  
    rational  pproximations to algebraic curves and surfaces.  
    Arbitrary rational parametric surfaces can be displayed in 
    GANITH, taking care of poles and base points. Animation 
    facilities allow the visualization of entire families of 
    algebraic curves and surfaces.

   Version 1 of GANITH is available from anonymous FTP at 
   ftp.cs.purdue.edu in the file /pub/shastra/bin/ganith-sun.tar.Z
