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.

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

-image2 file
