NAME
lavalite - 3D OpenGL simulation of a Lavalite.
SYNOPSIS
lavalite [-display host:display.screen] [-window] [-root] [-visual visual] [-delay microseconds] [-fps] [-style style ] [-spin xyz ] [-no-spin ] [-speed float ] [-resolu tion integer ] [-count integer ] [-no-smooth ] [-wireframe ] [-impatient ] [-lava-color color ] [-fluid-color color ] [-base-color color ] [-table-color color ] [-fluid-texture filename ] [-base-texture filename ] [-table-texture file_ name ]
DESCRIPTION
The lavalite program displays a 3D simulation of the
famous lamp of the same name. It requires a fast computer
with fast OpenGL support.
OPTIONS
lavalite accepts the following options:
- -window Draw on a newly-created window. This is the
- default.
- -root Draw on the root window.
- -visual visual
- 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. - -style style
- Specify which model of lamp to draw. Available
models are: Classic, Giant, Cone, and Rocket. Default: random. - -spin xyz
- Around which axes the model should auto-spin.
Defaults to "Z", meaning it rotates horizontally,
but otherwise pitch or roll. - -no-spin
- Same as -spin ''.
- -speed float
- 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: 0.003. - -delay usecs
- The delay between steps of the animation; default
is 40000 (1/25th second.) - -resolution integer
- The size of the grid from which the mesh is cre
ated 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 conjunction with
-delay 0, this can be a useful benchmark of your GL performance. - -count integer
- The maximum number of blobs that can be in motion
at once. Default: 3. - -no-smooth
- Turn off smoothing: the objects in the scene will
be facetted. - -wireframe
- Render all objects in wireframe instead of as
solids. - -impatient
- Provide this option if you are. This will prewarm the lamp, so when it starts up, the first
frame will show a blob already halfway up the
lamp. - -lava-color color
- Specifies the color of the blobbies. Default:
red. - -fluid-color color
- Specifies the color of the fluid that the blobbies
float in. Default: light blue. - -base-color color
- Specifies the color of the lamp base, and the cap
on top of the bottle. Default: very dark gray. - -table-color color
- Specifies the color of the table that the lamp is
sitting on. Default: black (meaning it is invisi
ble.) - -fluid-texture filename
- An image file to wrap around the glass.
- Note that on most systems, GL textures must have
dimensions that are a power of two. - 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". Otherwise, the combination of the two
might be too dark to see. - -base-texture filename
- An image file to wrap around the base of the lamp,
and the cap on top of the bottle. - -table-texture texture
- An image file to spread across the table that the
lamp is sitting on.
ENVIRONMENT
DISPLAY to get the default host and display number.

the global resources stored in the RESOURCE_MAN
AGER property.
