KIPP3D is a suite of programs for creating contour/topographic and
three-dimensional surface plots from ASCII data.  It was originally 
written for DOS, but works great under Windows 95/98/NT.  In fact, 
under Win 95/98/NT, it will take advantage of any properly installed
printer/plotter capable of graphical output.  

The program is Shareware ($39.95).

Quick documentation is available in the ASCII file README.TXT.  The 
full manual is supplied as MANUAL.DOC in WORD 7.0 format.  (It is 
also available as a bound hardcopy.)
