NAME

       ico - animate an icosahedron or other polyhedron

SYNOPSIS

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

DESCRIPTION

       Ico displays a wire-frame rotating polyhedron, with hidden lines removed, 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 information 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 TERMINATION

       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 format 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 elsewhere), simply do a 'make depend'.  This will recreate the file
       allobjs.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.
