NAME

       glplanet - rotating 3d texture-mapped planet.

SYNOPSIS

       glplanet  [--display  host:display.screen]  [--visual  visual]  [--window]  [--root] [--window-id number]
       [--delay number] [--image file] [--image2  file]  [--mode  string]  [--resolution  number]  [--wireframe]
       [--fps]

DESCRIPTION

       Draws  a  planet  bouncing around in space.  The built-in images are day and night maps of the Earth, but
       you can wrap any Equirectangular-projected map onto the sphere, e.g.,  the  planetary  textures  included
       with ssystem.

OPTIONS

       --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.

       --window
               Draw on a newly-created window.  This is the default.

       --root  Draw on the root window.

       --window-id number
               Draw on the specified window.

       --delay number
               Per-frame delay, in microseconds.  Default: 20000 (0.02 seconds.).

       --image file
               The day texture map to wrap around the planet's surface.

       --image2 file
               The night texture map to wrap around the planet's surface.  The two will be blended  together  at
               the dusk terminator.

       --mode globe
               All is right with the world.

       --mode equirectangular
               Wat.

       --mode mercator
               Good day, Sir. I said GOOD DAY.

       --resolution
               The resolution of the planetary mesh. Default: 128.

       --wireframe
               Render in wireframe instead of solid.

       --fps   Display the current frame rate, CPU load, and polygon count.

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.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.
