Name: XTAL4POV 2.0
Description: Crystal shape generator for POVRay 2.x
Author: Klaus Kosten (kosten@kristall.xtal.rwth-aachen.de)

This program generates POVRay 2.x compatible data files (intersections of
planes) of arbitrary crystal shapes, which can be #include'd in scenes.
No crystallographic knowledge is required, though it may be useful; all the
user has to know is how to type in some letters and numbers. Then the program
will automatically generate crystallographically correct crystal shapes. It may
require some trial and error to get exactly what one wants, though, and
therefore I have included a *very* brief introduction to geometrical crys-
tallography, which can help understanding what the program is doing. The program
runs under MS-DOS, but porting to other platforms should be no problem, since
the source is included, and I tried to adhere to the standards.
The files in xtal4pov.zip are

xtal4pov.exe        The MS-DOS executable, compiled with MS C 6.00
xtal4pov.c          The source (also compiles under DJGPP)
xtal4pov.doc        The necessary documentation
intro.doc           Additional information about crystallographic basics
platon.inc          A POVRay 2.0 compatible include file, containing the
                    five platonic solids
xtal4pov.txt        This file

This whole package is in the Public Domain and may be used and distributed
freely.
