3 polyhedra - draws the 80 uniform polyhedra and their duals

13 [\-duration \fIseconds\fP]
22 This program renders 160 different 3D solids, and displays some
23 information about each. A new solid is chosen every few seconds.
25 There are 75 uniform polyhedra, plus an inifinite number of
26 prisms and antiprisms:
28 * Convex Uniform Polyhedra:
30 * Archimedean solids (13)
31 * Convex prisms and antiprisms (2 infinite families)
32 * Nonconvex Uniform Polyhedra:
33 * Kepler-Poinsot polyhedra (4)
34 * Nonconvex uniform polyhedra (53)
35 * Nonconvex prisms, antiprisms, and crossed antiprisms
38 Representative samples of the prism sets brings the total to 80 solids.
39 Including the \fIdual\fP of each brings the total up to 160. (To
40 create the "dual" of a polyhedron, faces are replaced with vertices,
41 and vertices with faces.)
44 .B \-visual \fIvisual\fP
45 Specify which visual to use. Legal values are the name of a visual class,
46 or the id number (decimal or hex) of a specific visual.
49 Draw on a newly-created window. This is the default.
52 Draw on the root window.
54 .B \-delay \fInumber\fP
55 Per-frame delay, in microseconds. Default: 30000 (0.03 seconds.).
57 .B \-speed \fInumber\fP
58 Larger numbers mean run faster. Default: 1.0.
60 .B \-duration \fIseconds\fP
61 How long before switching to a new polyhedron. Default 12 seconds.
63 .B \-wander | \-no-wander
64 Whether the objects should wander around the screen.
66 .B \-spin [XYZ] | \-no-spin
67 Which axes, if any, to spin around on.
69 .B \-titles | \-no-titles
70 Whether to display text describing each object.
72 .B \-which \fIobject-name\fP
73 Display only one particular object, identified by number, name, or
76 .B \-wireframe | \-no-wireframe
77 Render in wireframe instead of solid.
80 Display the current frame rate, CPU load, and polygon count.
82 When running in a window, you can rotate the object with the mouse.
83 Also, the following keystrokes are defined:
86 Select a new polyhedron at random.
89 Select the next-higher-numbered polyhedron.
92 Select the next-lower-numbered polyhedron.
100 to get the default host and display number.
103 to get the name of a resource file that overrides the global resources
104 stored in the RESOURCE_MANAGER property.
