The lavalite program displays a 3D simulation of the famous lamp of the same name. It
requires a fast computer with fast OpenGL support.
lavalite accepts the following options:
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
Specify which visual to use. Legal values are the name of a visual class, or the
id number (decimal or hex) of a specific visual.
Specify which model of lamp to draw. Available models are: Classic, Giant, Cone,
and Rocket. Default: random.
Around which axes the model should auto-spin. Defaults to "Z", meaning it rotates
horizontally, but otherwise pitch or roll.
Same as -spin ''.
A number controlling the frequency at which new blobs launch: you can think of
this as being related to the the heat of the lightbulb in the base. Default:
The delay between steps of the animation; default is 40000 (1/25th second.)
The size of the grid from which the mesh is created that is used to polygonize the
blobs. higher values will give very smooth looking blobs, at the expense of
speed. Default: 40.
The options "-resolution 10 -no-smooth" look kind of interesting.
-fps Display a running tally of how many frames per second are being rendered. In con-
junction with -delay 0, this can be a useful benchmark of your GL performance.
The maximum number of blobs that can be in motion at once. Default: 3.
Turn off smoothing: the objects in the scene will be facetted.
Render all objects in wireframe instead of as solids.
Provide this option if you are. This will pre-warm the lamp, so when it starts
up, the first frame will show a blob already halfway up the lamp.
Specifies the color of the blobbies. Default: red.
Specifies the color of the fluid that the blobbies float in. Default: light blue.
Specifies the color of the lamp base, and the cap on top of the bottle. Default:
very dark gray.
Specifies the color of the table that the lamp is sitting on. Default: black
(meaning it is invisible.)
An image file to wrap around the glass.
Note that on most systems, GL textures must have dimensions that are a power of
Note also that colors and textures are both applied: so, if you apply a texture
and it isn't showing up, try specifying the corresponding color as "white". Oth-
erwise, the combination of the two might be too dark to see.
An image file to wrap around the base of the lamp, and the cap on top of the bot-
An image file to spread across the table that the lamp is sitting on.
DISPLAY to get the default host and display number.
to get the name of a resource file that overrides the global resources stored in
the RESOURCE_MANAGER property.
