SYNOPSIS

        polyhedra  [-display  host:display.screen]  [-visual  visual] [-window]

DESCRIPTION

        This program renders 160 different 3D solids, and displays some  infor-
        mation about each.  A new solid is chosen every few seconds.
 
        There  are 75 uniform polyhedra, plus an inifinite number of prisms and
        antiprisms:
 
          * Convex Uniform Polyhedra:
            * Platonic solids (5)
            * Archimedean solids (13)
            * Convex prisms and antiprisms (2 infinite families)
          * Nonconvex Uniform Polyhedra:
            * Kepler-Poinsot polyhedra (4)
            * Nonconvex uniform polyhedra (53)
            * Nonconvex prisms, antiprisms, and crossed antiprisms
              (3 infinite families)
 
        Representative samples of the prism sets brings the total to 80 solids.
        Including  the dual of each brings the total up to 160.  (To create the
        "dual" of a polyhedron, faces are replaced with vertices, and  vertices
        with faces.)
 

OPTIONS

        -visual visual
                Specify  which  visual  to use.  Legal values are the name of a
                visual class, or the id number (decimal or hex) of  a  specific
                visual.
 
        -window Draw on a newly-created window.  This is the default.
 
        -root   Draw on the root window.
 
        -delay number
                Per-frame  delay,  in  microseconds.  Default: 30000 (0.03 sec-
                onds.).
 
        -speed number
                Larger numbers mean run faster.  Default: 1.0.
 
        -duration seconds
                How long before switching to a new polyhedron.  Default 12 sec-
                onds.
 
        -wander | -no-wander
                Whether the objects should wander around the screen.
 
        -spin [XYZ] | -no-spin
                Which axes, if any, to spin around on.
 
        -titles | -no-titles
                Whether to display text describing each object.
 
        -which object-name
                Display only one particular object, identified by number, name,
                or Whthoff symbol.
 
        -wireframe | -no-wireframe
                Render in wireframe instead of solid.
 
        -fps    Display the current frame rate, CPU load, and polygon count.
        When running in a window, you can rotate the  object  with  the  mouse.
        Also, the following keystrokes are defined:
 
        SPC or TAB  Select a new polyhedron at random.
 
        + or >      Select the next-higher-numbered polyhedron.
 
        - or <      Select the next-lower-numbered polyhedron.
 
        ESC or ^C   Quit.
 

ENVIRONMENT

        DISPLAY to get the default host and display number.
 
        XENVIRONMENT
                to  get  the  name of a resource file that overrides the global
                resources stored in the RESOURCE_MANAGER property.
