  15 This manual is for `sketch', version 0.2 (build 161),
  16 Tuesday, September 08, 2009, a program that converts descriptions of simple
  17 three-dimensional scenes into static drawings. This version generates
  18 `PSTricks' or `PGF/TikZ' code suitable for use with the
  19 TeX document processing system.

  57
  58 <p>The current version of <code>sketch</code> has no clipping
  59 <a name="index-clipping-497"></a>operations.  The entire scene is always drawn.  This means that when a
  60 perspective transform is employed, it is the user's responsibility to
  61 make sure the entire scene remains in front of the viewer, the region
  62 z&lt;0.
