NAME
       mxico - animate an icosahedron or other polyhedron

SYNOPSIS
       mxico  [-display	 display]  [-geometry geometry]	[-r] [-d pattern] [-i]
       [-dbl] [-faces] [-noedges] [-sleep n] [-obj object] [-objhelp] [-colors
       color-list]

DESCRIPTION
       Mxico displays a	wire-frame rotating polyhedron,	with hidden lines  re-
       moved, or a solid-fill polyhedron with hidden faces removed.  There are
       a  number  of different polyhedra available; adding a new polyhedron to
       the program is quite simple.

OPTIONS
       -r     Display on the root window instead of creating a new window.

       -d pattern
	      Specify a	bit pattern for	drawing	dashed lines for wire frames.

       -i     Use inverted colors for wire frames.

       -dbl   Use double buffering on the display.  This works for either wire
	      frame or solid fill drawings.  For solid	fill  drawings,	 using
	      this  switch  results  in	substantially smoother movement.  Note
	      that this	requires twice as many bit planes  as  without	double
	      buffering.   Since  some colors are typically allocated by other
	      programs,	most eight-bit-plane displays will probably be limited
	      to eight colors when using double	buffering.

       -faces Draw filled faces	instead	of wire	frames.

       -noedges
	      Don't draw the wire frames.  Typically used only when -faces  is
	      used.

       -sleep n
	      Sleep n seconds between each move	of the object.

       -obj object
	      Specify  what  object  to	 draw.	 If no object is specified, an
	      icosahedron is drawn.

       -objhelp
	      Print out	a list of the available	objects, along	with  informa-
	      tion about each object.

       -colors color color ...
	      Specify  what  colors should be used to draw the filled faces of
	      the object.  If less colors than faces are given,	the colors are
	      reused.

PROGRAM	TREMINATION
       Pressing	"q" will close a window. If compiled with threads support, the
       program will stop only when all threads terminate. You can  also	 close
       an  animation  window using the ICCCM delete message (depending on your
       window manager, you will	have a decoration button or menu to send  such
       message).

ADDING POLYHEDRA
       If  you	have the source	to ico,	it is very easy	to add more polyhedra.
       Each polyhedron is defined in an	include	file by	the name of  objXXX.h,
       where XXX is something related to the name of the polyhedron.  The for-
       mat of the include file is defined in the file polyinfo.h.  Look	at the
       file  objcube.h to see what the exact format of an objXXX.h file	should
       be, then	create your objXXX.h file in that format.

       After making the	new objXXX.h file (or copying in a new one from	 else-
       where),	simply	do  a  'make depend'.  This will recreate the file al-
       lobjs.h,	which lists all	of the objXXX.h	files.	Doing a	 'make'	 after
       this will rebuild ico with the new object information.

BUGS
       Pyramids	and tetrahedrons with filled faces do not display correctly.

       A  separate  color cell is allocated for	each name in the -colors list,
       even when the same name may be specified	twice.	Color allocation fails
       in TrueColor displays and option	-faces does not	work well.
