NAME

       glplanet - rotating 3d texture-mapped planet.

SYNOPSIS

       glplanet [-display host:display.screen] [-visual visual] [-window] [-root] [-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.

       -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.
