DESCRIPTION

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.

OPTIONS

21       lavalite accepts the following options:
22
23       -window Draw on a newly-created window.  This is the default.
24
25       -root   Draw on the root window.
26
27       -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
32       -style style
33               Specify  which  model  of  lamp to draw.  Available models are:
34               Classic, Giant, Cone, and Rocket.  Default: random.
35
36       -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
40       -no-spin
41               Same as -spin ''.
42
43       -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
48       -delay usecs
49               The  delay  between  steps  of  the animation; default is 30000
50               (0.03 second.)
51
52       -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
57               The options "-resolution 10 -no-smooth" look kind of  interest‐
58               ing.
59
60       -fps    Display the current frame rate, CPU load, and polygon count.
61
62       -count integer
63               The  maximum  number  of  blobs  that can be in motion at once.
64               Default: 3.
65
66       -no-smooth
67               Turn off smoothing: the objects in the scene will be facetted.
68
69       -wireframe
70               Render all objects in wireframe instead of as solids.
71
72       -impatient
73               Provide this option if you are.  This will pre-warm  the  lamp,
74               so  when it starts up, the first frame will show a blob already
75               halfway up the lamp.
76
77       -lava-color color
78               Specifies the color of the blobbies.  Default: red.
79
80       -fluid-color color
81               Specifies the color of the fluid that the  blobbies  float  in.
82               Default: light blue.
83
84       -base-color color
85               Specifies the color of the lamp base, and the cap on top of the
86               bottle.  Default: very dark gray.
87
88       -table-color color
89               Specifies the color of the table that the lamp is  sitting  on.
90               Default: black (meaning it is invisible.)
91
92       -fluid-texture filename
93               An image file to wrap around the glass.
94
95               Note  that  on  most  systems, GL textures must have dimensions
96               that are a power of two.
97
98               Note also that colors and textures are both applied: so, if you
99               apply  a  texture  and  it isn't showing up, try specifying the
100               corresponding color as "white".  Otherwise, the combination  of
101               the two might be too dark to see.
102
103       -base-texture filename
104               An  image file to wrap around the base of the lamp, and the cap
105               on top of the bottle.
106
107       -table-texture texture
108               An image file to spread across the table that the lamp is  sit‐
109               ting on.
110

ENVIRONMENT

112       DISPLAY to get the default host and display number.
113
114       XENVIRONMENT
115               to  get  the  name of a resource file that overrides the global
116               resources stored in the RESOURCE_MANAGER property.
