Flightgear Subsystems
The Flightgear and Simgear codebase can be broken down into subsystems. Some of these are Managed and accessed through simgear's SGSubsystemMgr. Others have their own componentManager independent of SGSubsystemMgr. Still others have no Manager function per se.
The lists below give starting points for exploration of the various subsystems in Flightgear/Simgear. As a person new to the Flightgear projects codebase, I think its important to understand the code in the following areas in some detail:
- How Sub-Systems are managed
- How the main event loop works
- How properties are set and how their values are accessed. This includes understanding the concept of "tied" properties.
- How I/O works, especially I/O used for communications
Simgear Subsystem Groups
The information below is intended to serve as a starting point for exploring code releated to these subsystems.
Work in progress This article or section will be worked on in the upcoming hours or days. See history for the latest developments. |
