       color  ]	 [-base-color  color  ]	 [-table-color color ] [-fluid-texture
       filename ] [-base-texture filename ] [-table-texture filename ]

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  interest‐
	       ing.

       -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  sit‐
	       ting 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.
