NAME

       lavalite - 3D OpenGL simulation of a Lavalite.

SYNOPSIS

       lavalite  [-display host:display.screen] [-window] [-root] [-visual visual] [-delay microseconds] [-fps] [-style style ] [-spin xyz ] [-no-
       spin ] [-speed float ] [-resolution integer ] [-count integer ] [-no-smooth ] [-wireframe ] [-impatient ]  [-lava-color	color  ]  [-fluid-
       color 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 light-
	       bulb in the base.  Default: 0.003.

       -delay usecs
	       The delay between steps of the animation; default is 40000 (1/25th 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	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.

       -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  half-
	       way 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 corre-
	       sponding 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.
