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.
- -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 30000 (0.03
second.)
- -resolution
integer
- 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 the current frame rate, CPU load, and polygon count.
- -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 pre-warm 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 invisible.)
- -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.
- DISPLAY
- to get the default host and display number.
- XENVIRONMENT
- to get the name of a resource file that overrides the global resources
stored in the RESOURCE_MANAGER property.
