26 !!DESCRIPTION
27
28
29 The ''hyperball'' program displays a wireframe projection
30 of a hyperball which is rotating at user-specified rates
31 around any or all of its four axes.
32 !!OPTIONS
33
34
35 ''hyperball'' accepts the following options:
36
37
38 __-window__
39
40
41 Draw on a newly-created window. This is the
42 default.
43
44
45 __-root__
46
47
48 Draw on the root window.
49
50
51 __-mono__
52
53
54 If on a color display, pretend we're on a monochrome
55 display.
56
57
58 __-install__
59
60
61 Install a private colormap for the window.
62
63
64 __-visual__ ''visual''
65
66
67 Specify which visual to use. Legal values are the name of a
68 visual class, or the id number (decimal or hex) of a
69 specific visual.
70
71
72 __-delay__ ''microseconds''
73
74
75 How much of a delay should be introduced between steps of
76 the animation. Default 100000, or about 1/10th
77 second.
78
79
80 __-observer-z__ ''int''
81
82
83 How far away the observer is from the center of the cube
84 (the cube is one unit per side.) Default 5.
85
86
87 __-xw__ ''float''
88
89
90 __-xy__ ''float''
91
92
93 __-xz__ ''float''
94
95
96 __-yw__ ''float''
97
98
99 __-yz__ ''float''
100
101
102 __-zw__ ''float''
103
104
105 The amount that the ball should be rotated around the
106 specified axis at each frame of the animation, expressed in
107 radians. These should be small floating-point values (less
108 than 0.05 works best.) Default: xy=0.01, xz=0.005,
109 yw=0.01.
110 !!ENVIRONMENT
111
112
113 __DISPLAY__
114
115
