3 This directory contains the main routine for FlightGear, together with
4 various utility classes and functions that do not fit in anywhere
5 else, and subsystems that have not yet graduated to having their own
6 directories (because the maintainers are lazy, not because the
7 subsystems are not important).
11 This module defines a global function to register FlightGear's
16 This module defines global functions to initialize for the various
17 subsystems. Code is gradually being moved out of here and into the
18 subsystems' own init() methods, so this module will eventually
23 This module defines high-level global I/O functions for FlightGear.
24 I don't know how widely these are used, yet.
28 This module provides a FlightGear layer over the SimGear property
29 manager. This module performs two roles: it provides global
30 convenience functions for accessing the FlightGear property tree,
31 and it ties some properties to its own static functions. The second
32 role has mostly disappeared, since subsystems now tie their own
33 properties in their bind() methods, and eventually this module will
34 contain only the convenience functions.
38 This module defines FGSubsystem, the abstract base class (or
39 interface) for subsystems in FlightGear. Most of the important
40 subsystems already extend this class, and eventually, all subsystems
45 This module defines FGGlobals, a class that holds pointers to
46 subsystems and other variables used by a FlightGear session. Many
47 global variables have migrated into here, and eventually, all will,
48 so that the program can maintain state for more than one session at
53 This module defines the FGLogger subsystem, which allows the user to
54 log any property value to any number of CSV files, somewhat like an
55 overenthusiastic flight data recorder.
58 This file defines the main() function for FlightGear as well as the
59 top-level loop. Currently, there is a still lot of code in here
60 that belongs in the individual subsystems' init() and update()
61 methods; eventually, this will be a short, simple file defining the
62 top-level flow logic of the program.
66 This module defines global functions for parsing command-line
67 options and transferring them to the property tree.
71 This is a batch file for launching FlightGear under MSWindows.
72 runfgfs.bat is autogenerated from runfgfs.bat.in, so any changes
73 should be made to the latter file.
77 This module defines global functions for displaying and updating the
82 This module defines the FGViewer subsystem, which calculates the
83 viewpoint in world coordinates and provides transformation matrices
84 for the scenery code. FGViewer has methods that allow the program
85 to rotate or move the current view direction.
89 This module defines the FGViewMgr subsystem, which manages all of
90 the different views available in FlightGear.
