DESCRIPTION

16       This program renders 160 different 3D solids, and displays some  infor‐
17       mation about each.  A new solid is chosen every few seconds.
18
19       There  are 75 uniform polyhedra, plus an inifinite number of prisms and
20       antiprisms:
21
22         * Convex Uniform Polyhedra:
23           * Platonic solids (5)
24           * Archimedean solids (13)
25           * Convex prisms and antiprisms (2 infinite families)
26         * Nonconvex Uniform Polyhedra:
27           * Kepler-Poinsot polyhedra (4)
28           * Nonconvex uniform polyhedra (53)
29           * Nonconvex prisms, antiprisms, and crossed antiprisms
30             (3 infinite families)
31
32       Representative samples of the prism sets brings the total to 80 solids.
33       Including  the dual of each brings the total up to 160.  (To create the
34       "dual" of a polyhedron, faces are replaced with vertices, and  vertices
35       with faces.)

OPTIONS

38       --visual visual
39               Specify  which  visual  to use.  Legal values are the name of a
40               visual class, or the id number (decimal or hex) of  a  specific
41               visual.
42
43       --window
44               Draw on a newly-created window.  This is the default.
45
46       --root  Draw on the root window.
47
48       --window-id number
49               Draw on the specified window.
50
51       --delay number
52               Per-frame  delay,  in  microseconds.  Default: 30000 (0.03 sec‐
53               onds.).
54
55       --speed number
56               Larger numbers mean run faster.  Default: 1.0.
57
58       --duration seconds
59               How long before switching to a new polyhedron.  Default 12 sec‐
60               onds.
61
62       --wander | --no-wander
63               Whether the objects should wander around the screen.
64
65       --spin [XYZ] | --no-spin
66               Which axes, if any, to spin around on.
67
68       --titles | --no-titles
69               Whether to display text describing each object.
70
71       --which object-name
72               Display only one particular object, identified by number, name,
73               or Whthoff symbol.
74
75       --wireframe | --no-wireframe
76               Render in wireframe instead of solid.
77
78       --fps   Display the current frame rate, CPU load, and polygon count.
79

KEY BINDINGS

81       When running in a window, you can rotate the  object  with  the  mouse.
82       Also, the following keystrokes are defined:
83
84       SPC or TAB  Select a new polyhedron at random.
85
86       + or >      Select the next-higher-numbered polyhedron.
87
88       - or <      Select the next-lower-numbered polyhedron.
89
90       ESC or ^C   Quit.
91

ENVIRONMENT

93       DISPLAY to get the default host and display number.
94
95       XENVIRONMENT
96               to  get  the  name of a resource file that overrides the global
97               resources stored in the RESOURCE_MANAGER property.
98
99       XSCREENSAVER_WINDOW
100               The window ID to use with --root.
