       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

       -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.

               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

       -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.

               Turn off smoothing: the objects in the scene will be facetted.

               Render all objects in wireframe instead of as solids.

               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.

               to  get  the  name of a resource file that overrides the global
               resources stored in the RESOURCE_MANAGER property.
