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.
