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.
