15 This program renders 160 different 3D solids, and displays some infor‐
16 mation about each. A new solid is chosen every few seconds.
17 There are 75 uniform polyhedra, plus an inifinite number of prisms and
19 antiprisms:
20 * Convex Uniform Polyhedra:
22 * Platonic solids (5)
23 * Archimedean solids (13)
24 * Convex prisms and antiprisms (2 infinite families)
25 * Nonconvex Uniform Polyhedra:
26 * Kepler-Poinsot polyhedra (4)
27 * Nonconvex uniform polyhedra (53)
28 * Nonconvex prisms, antiprisms, and crossed antiprisms
29 (3 infinite families)
30 Representative samples of the prism sets brings the total to 80 solids.
32 Including the dual of each brings the total up to 160. (To create the
33 "dual" of a polyhedron, faces are replaced with vertices, and vertices
34 with faces.)
35
37 -visual visual
38 Specify which visual to use. Legal values are the name of a
39 visual class, or the id number (decimal or hex) of a specific
40 visual.
41 -window Draw on a newly-created window. This is the default.
43 -root Draw on the root window.
45 -delay number
47 Per-frame delay, in microseconds. Default: 30000 (0.03 sec‐
48 onds.).
49 -speed number
51 Larger numbers mean run faster. Default: 1.0.
52 -duration seconds
54 How long before switching to a new polyhedron. Default 12 sec‐
55 onds.
56 -wander | -no-wander
58 Whether the objects should wander around the screen.
59 -spin [XYZ] | -no-spin
61 Which axes, if any, to spin around on.
62 -titles | -no-titles
64 Whether to display text describing each object.
65 -which object-name
67 Display only one particular object, identified by number, name,
68 or Whthoff symbol.
69 -wireframe | -no-wireframe
71 Render in wireframe instead of solid.
72 -fps Display the current frame rate, CPU load, and polygon count.
74
76 When running in a window, you can rotate the object with the mouse.
77 Also, the following keystrokes are defined:
78 SPC or TAB Select a new polyhedron at random.
80 + or > Select the next-higher-numbered polyhedron.
82 - or < Select the next-lower-numbered polyhedron.
84 ESC or ^C Quit.
86
88 DISPLAY to get the default host and display number.
89 XENVIRONMENT
91 to get the name of a resource file that overrides the global
92 resources stored in the RESOURCE_MANAGER property.
