ICO(1X11)               COMMAND REFERENCE               ICO(1X11)



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]

     This is a user-contributed client.

DESCRIPTION
     The ico program 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.

USES
     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), run the command make depend.  This will
     recreate the file allobjs.h, which lists all of the objXXX.h
     files.  Running the make command after this will rebuild ico
     with the new object information.

CAVEATS
     A separate color cell is allocated for each name in the
     -colors list, even when the same name may be specified
     twice.
