---------------------------------------------------------
What is it?

 ZPLOT is a 3D plotting program under X11. It can plot
   -- Graph of a two variable function
   -- Parametric surface  (wireframe or flat shaded)
   -- Tube around a 3D curve
   -- Rectangular mesh Data 
   -- OFF data  /* support is limited */
   -- 3D lines, points.
   -- Contours (on surfaces)
 It allows you set up lighting and material interactively.
 It support interactive rotation and zooming.
 It support Postscript and PPM outputs.

 Zplot uses only Xlib. It was developed on a Linux machine
 running XFree 2.1, (XFree3.1 now). It has been compiled and
 tested on
    SunSparc, IBMR6000 and i486-Linux

  REMARK:  Zplot only runs on 8bit PseudoColor or Grayscale
           visuals !
------------------------------------------------------------
How to get it?

  Zplot is availabel on

    math.utexas.edu  /pub/tmp/XPLOT.TGZ
    ftp.x.org        /contrib/applications/XPLOT.TGZ
    (notice the file is XPLOT.TGZ !!!)
------------------------------------------------------------
How to install it?

  get the distribution XPLOT.TGZ
  mkdir ZPLOT
  cd    ZPLOT
  gzip -dc ../XPLOT.TGZ | tar xvf -
  make
  cp zplot     to_whatever_place_you_want_it_to_be

    If it fails, you may have to edit the first 3 lines of Makefile.
    The examples directory contains a few examples you can
  test the program.
    The doc directroy contains a sketchy tutorial.

Credits:
  The front end code was taken from IRISPLOT written 4 years ago,
  which is a hack from Gnuplot, for the SGI graphics workstations.
  The back end code was developed using the Vogl library.
------------------------------------------------------------
Bugs:
  It core dumps when either the front end generates an NaN/Infinity 
  or data file contains an NaN/Infinity
