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.

       --window-id number
               Draw on the specified 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.

ENVIRONMENT

       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.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.
