NAME

       glplanet - rotating 3d texture-mapped planet.

SYNOPSIS

       glplanet  [-display host:display.screen] [-visual visual] [-window] [-root] [-delay number] [-image file]
       [-image2 file] [-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.

       -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.

       -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.
