                               Nov 2000
Introduction
------------
   Plot3DF is an abstract C++ class used to plot an arbitrary equation
   F(x,y,z)=0 as a 3D surface. Root searching techniques are used to
   plot cross sections of the surface.  Hidden line removal and color
   gradients are optional.

   Win3DF.exe is a VC++ 6.0 MFC Windows program that uses the Plot3DF
   class to draw 3D plots.

   Full source code is provided as freeware.
   Abstract C++ base classes are portable to other platforms.

   4) User selectable 3D view point
   5) Multiple views can be shown
   6) Supports hidden line removal.
   7) Has the ability to produce color gradient plots.
   8) Clipping capability
