fgviewer - An alternative FlightGear viewer application
fgviewer [--fg-root rootdir] [--fg-scenery scenerydir] [--config configfile] [--prop property value] [--renderer rend] [--hla] [--federation fed]
fgviewer is a viewer application that allows you to examine FlightGear scenery and objects without starting fgfs(1).
--fg-root rootdir Set the FlightGear data root directory ($FG_ROOT) to rootdir. If this option is not set, fgviewer uses the path specified in the FG_ROOT environment variable or, absent that, the FlightGear data directory chosen at the time the program was compiled. --fg-scenery scenerydir Set the FlightGear scenery directory ($FG_SCENERY) to scenerydir. If this option is not set, fgviewer uses the path specified in the FG_SCENERY environment variable or, absent that, the Scenery subdirectory inside $FG_ROOT. --config configfile Read configuration directives from configfile. --prop property value Set the property named property to value. --renderer rend Use the renderer named rend to render the scenery. This option is currently not supported. --hla Enable HLA federation. --federation fed Enable a custom federation named fed.
fgviewer exits with EXIT_SUCCESS on success, with EXIT_FAILURE if the syntax of the command-line arguments is wrong or an error occurs.
FG_ROOT If FG_ROOT is set and --fg-root is not set, it specifies the root data directory to use. FG_SCENERY If FG_SCENERY is set and --fg-scenery is not set, it specifies the scenery directory to use.
$FG_ROOT/defaults.xml Default preferences file loaded on startup.
