Anybody working on FG's source code, should be aware of the [[FGViewer]] trend (decoupling the viewer from the simulation using a [http://wiki.flightgear.org/FlightGear_Headless headless mode] 1) to improve frame rate and latencies, but 2) also to support distributed multi-screen setups) and also the long-term goal to use [http://trac.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a00108.html OSG's CompositeViewer] for all of the FG views - so modifications to the existing viewer in $FG_SRC/Viewer should probbaly keep these things in mind to align well with other ongoing developments: http://wiki.flightgear.org/Howto:Use_a_Camera_View_in_an_Instrument#osgViewer::CompositeViewer | |||
An old PDF describing some of the challenges that FlightGear developers are trying to solve through HLA/[[FlightGear CIGI Support (Common Image Generator Interface)|CIGI]] adoption can be found at: http://wiki.flightgear.org/flightgear_wiki/images/1/1e/New_FG_architecture.pdf | |||
The FlightGear state of all HLA things is documented at: http://wiki.flightgear.org/FlightGear_HLA_support_(High_Level_Architecture) | |||
Introductory HLA resources are collected at: http://wiki.flightgear.org/Developing_with_HLA#Resources | |||
In developer's terms, that mostly boils down to: | |||
* expect more and more viewer functionality to be decoupled from the simulator (fgviewer being the prototype here) | |||
* expect more and more viewer/GUI features to be made optional through a "headless" mode during startup | |||
* expect the 2D rendering backend (GUI, instruments, HUDs etc) to be increasingly unified through the [[Canvas]] system | |||
* expect more work towards better system-wide reinit/reset support: http://wiki.flightgear.org/Reset_%26_re-init | |||
* expect more subsystem to become re-initializable at runtime, so that they can be dynamically enabled/disabled to facilitate the fgviewer or headless mode: http://wiki.flightgear.org/FlightGear_Run_Levels | |||
* expect more and and more mainloop subsystems to eventually become standalone threads/processes (really HLA federates) (FDM, AI traffic, scripting etc) to guarantee better viewer performance | |||
* expect OSG CompositeViewer to be eventually adopted (almost certainly not during the next 12 months though) | |||
Basically, help prepare these change by at least not making these things more difficult through your own code :) | |||

However, please take everything you'll find there with a grain of salt, because many of these articles haven't been updated over the years, so what may have seemed like a great idea 2-3 years ago, may already be depreciated meanwhile. On the other hand, those articles may still help you get a better understanding of architectural issues. | However, please take everything you'll find there with a grain of salt, because many of these articles haven't been updated over the years, so what may have seemed like a great idea 2-3 years ago, may already be depreciated meanwhile.
