polyhedra(6)		       XScreenSaver manual		    polyhedra(6)

NAME
     polyhedra - draws the 80 uniform polyhedra and their duals

SYNOPSIS
SYNOPSIS
     polyhedra	[--display  host:display.screen]  [--visual  visual]  [--window]
     [--root] [--window-id number] [--delay number] [--speed float]  [--duration
     seconds]  [--no-wander]  [--spin  XYZ] [--wireframe] [--no-titles] [--which
     name] [--wireframe] [--fps]

DESCRIPTION
     This program renders 160 different 3D solids, and displays some information
     about each.  A new solid is chosen every few seconds.

     There are 75 uniform polyhedra, plus an inifinite number of prisms and  an-
     tiprisms:

       * 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.

     --window-id number
	     Draw on the specified window.

     --delay number
	     Per-frame delay, in microseconds.	Default: 30000 (0.03 seconds.).

     --speed number
	     Larger numbers mean run faster.  Default: 1.0.

     --duration seconds
	     How long before switching to a new polyhedron.  Default 12 seconds.

     --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.

KEY BINDINGS
     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 re-
	     sources stored in the RESOURCE_MANAGER property.

     XSCREENSAVER_WINDOW
	     The window ID to use with --root.
