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 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.
