DESCRIPTION

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
18       There are 75 uniform polyhedra, plus an inifinite number of prisms  and
19       antiprisms:
20
21         * 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
31       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.)

OPTIONS

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

KEY BINDINGS

76       When  running  in  a  window, you can rotate the object with the mouse.
77       Also, the following keystrokes are defined:
78
79       SPC or TAB  Select a new polyhedron at random.
80
81       + or >      Select the next-higher-numbered polyhedron.
82
83       - or <      Select the next-lower-numbered polyhedron.
84
85       ESC or ^C   Quit.
86

ENVIRONMENT

88       DISPLAY to get the default host and display number.
89
90       XENVIRONMENT
91               to get the name of a resource file that  overrides  the  global
92               resources stored in the RESOURCE_MANAGER property.
