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.
