       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  interest-

       -fps    Display a running tally of how many frames per second are being
               rendered.  In conjunction with -delay 0, this can be  a  useful
               benchmark of your GL performance.

       -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 sit-
               ting 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.
