17 The lavalite program displays a 3D simulation of the famous lamp of the
18 same name. It requires a fast computer with fast OpenGL support.
19
21 lavalite accepts the following options:
22 -window Draw on a newly-created window. This is the default.
24 -root Draw on the root window.
26 -visual visual
28 Specify which visual to use. Legal values are the name of a
29 visual class, or the id number (decimal or hex) of a specific
30 visual.
31 -style style
33 Specify which model of lamp to draw. Available models are:
34 Classic, Giant, Cone, and Rocket. Default: random.
35 -spin xyz
37 Around which axes the model should auto-spin. Defaults to "Z",
38 meaning it rotates horizontally, but otherwise pitch or roll.
39 -no-spin
41 Same as -spin ''.
42 -speed float
44 A number controlling the frequency at which new blobs launch:
45 you can think of this as being related to the the heat of the
46 lightbulb in the base. Default: 0.003.
47 -delay usecs
49 The delay between steps of the animation; default is 30000
50 (0.03 second.)
51 -resolution integer
53 The size of the grid from which the mesh is created that is
54 used to polygonize the blobs. higher values will give very
55 smooth looking blobs, at the expense of speed. Default: 40.
56 The options "-resolution 10 -no-smooth" look kind of interest‐
58 ing.
59 -fps Display a running tally of how many frames per second are being
61 rendered. In conjunction with -delay 0, this can be a useful
62 benchmark of your GL performance.
63 -count integer
65 The maximum number of blobs that can be in motion at once.
66 Default: 3.
67 -no-smooth
69 Turn off smoothing: the objects in the scene will be facetted.
70 -wireframe
72 Render all objects in wireframe instead of as solids.
73 -impatient
75 Provide this option if you are. This will pre-warm the lamp,
76 so when it starts up, the first frame will show a blob already
77 halfway up the lamp.
78 -lava-color color
80 Specifies the color of the blobbies. Default: red.
81 -fluid-color color
83 Specifies the color of the fluid that the blobbies float in.
84 Default: light blue.
85 -base-color color
87 Specifies the color of the lamp base, and the cap on top of the
88 bottle. Default: very dark gray.
89 -table-color color
91 Specifies the color of the table that the lamp is sitting on.
92 Default: black (meaning it is invisible.)
93 -fluid-texture filename
95 An image file to wrap around the glass.
96 Note that on most systems, GL textures must have dimensions
98 that are a power of two.
99 Note also that colors and textures are both applied: so, if you
101 apply a texture and it isn't showing up, try specifying the
102 corresponding color as "white". Otherwise, the combination of
103 the two might be too dark to see.
104 -base-texture filename
106 An image file to wrap around the base of the lamp, and the cap
107 on top of the bottle.
108 -table-texture texture
110 An image file to spread across the table that the lamp is sit‐
111 ting on.
112
114 DISPLAY to get the default host and display number.
115 XENVIRONMENT
117 to get the name of a resource file that overrides the global
118 resources stored in the RESOURCE_MANAGER property.
