18 The lavalite program displays a 3D simulation of the famous lamp of the
19 same name. It requires a fast computer with fast OpenGL support.

22 lavalite accepts the following options:
23 --window
25 Draw on a newly-created window. This is the default.
26 --root Draw on the root window.
28 --window-id number
30 Draw on the specified window.
31 --visual visual
33 Specify which visual to use. Legal values are the name of a
34 visual class, or the id number (decimal or hex) of a specific
35 visual.
36 --style style
38 Specify which model of lamp to draw. Available models are:
39 Classic, Giant, Cone, and Rocket. Default: random.
40 --spin xyz
42 Around which axes the model should auto-spin. Defaults to "Z",
43 meaning it rotates horizontally, but otherwise pitch or roll.
44 --no-spin
46 Same as --spin ''.
47 --speed float
49 A number controlling the frequency at which new blobs launch:
50 you can think of this as being related to the the heat of the
51 lightbulb in the base. Default: 0.003.
52 --delay usecs
54 The delay between steps of the animation; default is 30000
55 (0.03 second.)
56 --resolution integer
58 The size of the grid from which the mesh is created that is
59 used to polygonize the blobs. higher values will give very
60 smooth looking blobs, at the expense of speed. Default: 40.
61 The options "-resolution 10 -no-smooth" look kind of interest‐
63 ing.
64 --fps Display the current frame rate, CPU load, and polygon count.
66 --count integer
68 The maximum number of blobs that can be in motion at once. De‐
69 fault: 3.
70 --no-smooth
72 Turn off smoothing: the objects in the scene will be facetted.
73 --wireframe
75 Render all objects in wireframe instead of as solids.
76 --impatient
78 Provide this option if you are. This will pre-warm the lamp,
79 so when it starts up, the first frame will show a blob already
80 halfway up the lamp.
81 --lava-color color
83 Specifies the color of the blobbies. Default: red.
84 --fluid-color color
86 Specifies the color of the fluid that the blobbies float in.
87 Default: light blue.
88 --base-color color
90 Specifies the color of the lamp base, and the cap on top of the
91 bottle. Default: very dark gray.
92 --table-color color
94 Specifies the color of the table that the lamp is sitting on.
95 Default: black (meaning it is invisible.)
96 --fluid-texture filename
98 An image file to wrap around the glass.
99 Note that on most systems, GL textures must have dimensions
101 that are a power of two.
102 Note also that colors and textures are both applied: so, if you
104 apply a texture and it isn't showing up, try specifying the
105 corresponding color as "white". Otherwise, the combination of
106 the two might be too dark to see.
107 --base-texture filename
109 An image file to wrap around the base of the lamp, and the cap
110 on top of the bottle.
111 --table-texture texture
113 An image file to spread across the table that the lamp is sit‐
114 ting on.
115
117 DISPLAY to get the default host and display number.
118 XENVIRONMENT
120 to get the name of a resource file that overrides the global
121 resources stored in the RESOURCE_MANAGER property.
122 XSCREENSAVER_WINDOW
124 The window ID to use with --root.
