Truchet tiling
--------------

This directory contains what I wrote for the contest proposed by
Denis Girou and Philippe Esperet at the GUTenberg congress on 
June 1 & 2, 1995. The problem is known as `Truchet tiling'. There were
two parts: coloration of lines, and colorations of surfaces.
Initially, the problem would have to be solved using pure PostScript
or PSTricks. I prefered to use METAPOST. A survey of all the solutions
will appear in a forthcoming issue of ``Les Cahiers GUTenberg''.


Main files in this directory:

  example.mp  : the METAPOST source file
  example.dvi : the example.mp source file formatted with `mft'.
  example.1   : METAPOST output (PostScript file)
  ...
  example.5   : METAPOST output (PostScript file)

  mproof.ps   : Output #5 formatted with mproof.tex.
                (i.e. in writing  tex 'mproof example.5')

  plain.mft   : the style needed for the application of `mft'

  readme.tex  : a presentation of the METAPOST techniques used (*in french*)
                (this file uses the `logo' fonts extended by Knuth)
   
  text.tex    : test file showing the five previous figures.

  tiling.mp   : the METAPOST macro file.
  tiling.dvi  : the tiling.mp source formatted with `mft'.
