NAME

       drawxtl - display crystal structures on ordinary computer hardware

SYNOPSIS

       drawxtl [filename]

DESCRIPTION

       drawxtl  reads  a  basic  description  of  the crystal structure, which includes unit-cell
       parameters, space group, atomic coordinates, thermal parameters  or  a  Fourier  map,  and
       outputs  a  geometry  object  that contains polyhedra, planes, lone-pair cones, spheres or
       ellipsoids, bonds, iso-surface Fourier contours and the unit-cell boundary.

       Four forms of graphics are produced:

       •   an OpenGL window for immediate viewing

       •   the Persistence of Vision Ray Tracer (POV-RAY) scene language for  publication-quality
           drawings

       •   the Virtual Reality Modeling Language (VRML) for dissemination across the Internet

       •   Postscript  rendering  of the OpenGL window for those who want high-quality output but
           do not have POV-RAY installed

OPTIONS

       There are no command line options to use.

FILES

       ~/.drawxtlrc
              Per user configuration file.

       A short  tutorial  about  this  file  and  configuring  drawxtl  is  available  online  at
       http://home.att.net/~larry.finger/drawxtl/configure.htm.

BUGS

       When  opening  a  structures (.str) file, drawxtl needs write permissions in the directory
       the file is located in. Otherwise  it  will  return  an  error  ("Cannot  open  structures
       files.").
