37 The \fIlavalite\fP program displays a 3D simulation of the famous lamp
38 of the same name. It requires a fast computer with fast OpenGL support.
41 accepts the following options:
44 Draw on a newly-created window. This is the default.
47 Draw on the root window.
49 .B \-visual \fIvisual\fP\fP
50 Specify which visual to use. Legal values are the name of a visual class,
51 or the id number (decimal or hex) of a specific visual.
53 .B \-style \fIstyle\fP\fP
54 Specify which model of lamp to draw. Available models
55 are: \fBClassic\fP, \fBGiant\fP, \fBCone\fP, and \fBRocket\fP.
59 Around which axes the model should auto-spin. Defaults to "Z", meaning
60 it rotates horizontally, but otherwise pitch or roll.
63 Same as \fB\-spin ''\fP.
65 .B \-speed \fIfloat\fP
66 A number controlling the frequency at which new blobs launch: you can
67 think of this as being related to the the heat of the lightbulb in
68 the base. Default: 0.003.
70 .B \-delay \fIusecs\fP
71 The delay between steps of the animation; default is 30000 (0.03 second.)
73 .B \-resolution \fIinteger\fP
74 The size of the grid from which the mesh is created that is used
75 to polygonize the blobs. higher values will give very smooth looking
76 blobs, at the expense of speed. Default: 40.
78 The options "-resolution 10 -no-smooth" look kind of interesting.
81 Display a running tally of how many frames per second are being rendered.
82 In conjunction with \fB\-delay 0\fP, this can be a useful benchmark of
85 .B \-count \fIinteger\fP
86 The maximum number of blobs that can be in motion at once.
90 Turn off smoothing: the objects in the scene will be facetted.
93 Render all objects in wireframe instead of as solids.
96 Provide this option if you are. This will pre-warm the lamp, so when it
97 starts up, the first frame will show a blob already halfway up the lamp.
99 .B \-lava-color \fIcolor\fP
100 Specifies the color of the blobbies. Default: red.
102 .B \-fluid-color \fIcolor\fP
103 Specifies the color of the fluid that the blobbies float in.
106 .B \-base-color \fIcolor\fP
107 Specifies the color of the lamp base, and the cap on top of the bottle.
108 Default: very dark gray.
110 .B \-table-color \fIcolor\fP
111 Specifies the color of the table that the lamp is sitting on.
112 Default: black (meaning it is invisible.)
114 .B \-fluid-texture \fIfilename\fP
115 An image file to wrap around the glass.
117 Note that on most systems, GL textures must have dimensions that are a
120 Note also that colors and textures are both applied: so, if you apply a
121 texture and it isn't showing up, try specifying the corresponding color
122 as "white". Otherwise, the combination of the two might be too dark to
125 .B \-base-texture \fIfilename\fP
126 An image file to wrap around the base of the lamp, and the cap on top
129 .B \-table-texture \fItexture\fP
130 An image file to spread across the table that the lamp is sitting on.
135 to get the default host and display number.
138 to get the name of a resource file that overrides the global resources
139 stored in the RESOURCE_MANAGER property.
