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.
