[Flightgear-devel] Fwd: FlightGear network protocol
Hello people from the FlightGear team, Let me first introduce myself ;) I'm a home cockpit builder from Eindhoven, The Netherlands, and I'm researching the possibility of using FlightGear as a flight dynamics server for medium to large cockpit setups. Amongst other things I'm developing my own instruments in OpenGL, and we're using FS2004 for the visual system (since the European scenery in FlightGear is still somewhat, absent.). Our goal would be to use the FlightGear system in an educational simulator for a Fokker F28 aircraft, at the school I'm about to attend (Aerospace Engineering in Delft). The only hiccup in the system right now is tying every bit together. The instruments render perfectly and FS2004 works a treat as a visual display (like the PS1 guys do), but the network still causes some trouble. Main thing is that I can't find the documentation for the protocol used by FlightGear for data I/O. The Wiki has the docs for the HTTP and the telnet protocol, but pulling large amounts of data out of that is pretty impossible. Note that everything is connected through a LAN and the ideal case would be to use a multicast to connect some systems together, but I'm still unsure whether that's possible. The packet format used by FlightGear is the main concern right now. Regards, Robin van Steenbergen Using Tomcat but need to do more? Need to support web services, security?

The documentation is in the source code. In your case it's located in FlightGear/src/Network/net_ctrls.hxx and/or FlightGear/src/Network/net_fdm.hxx There is also a small example application located in FlightGear/examples/netfdm Erik Great. I'll sift through the header files and see what I can dig up. Is there also a way to run FGFS as a pure flight dynamics server (thus disabling the visual system)? That would reduce the strain on the FDM system a bit and we might be able to make do with some salvaged PC's for the numbers. Using Tomcat but need to do more? Need to support web services, security?

While you're at it, why not look for a spot at the Flight Simulator Weekend, Nov. 4 and 5, 2006, Aviodrome Aviation Museum, Lelystad. (That's the weekend following the Linux World Expo). As a simbuilder I already have a place there, but I believe there's lot more room for more people. Just have a look at www.fsweekend.com for more info.

Re: [Flightgear-devel] HUD: raw gl-commands vs. plib/osg wrappers
Melchior FRANZ schreef: We had talked about abstracting out the raw gl-commands into just one file, and then to use plib wrappers to plug the HUD into the scene graph. The plib wrappers could eventually get replaced by osg wrappers. The abstraction is still a goal, and so is plugging the HUD into the scene graph. But I think now that using plib/osg wrappers is a bad idea. This would prevent us from using some gl features for absolutely no good reason (e.g. line width, clipping, ...). And finally, ogl *is* a standard, while neither plib nor osg are. So why leaving the standard? Raw gl-code can still be plugged into the scene graph via callbacks, and the only thing that the wrappers would buy us is management of state changes for performance reasons. But the HUD code doesn't change that much, and this can be done manually, too. Why exactly would we want to limit ourselves? :-} m. I quite agree with this. The double advantage that you have is that you can use existing rendering code from other packages (e.g. OpenGC) since they boil down to raw OpenGL calls if you take an abstract look (from a GPU point of view). Rendering to texture would allow us to use those glass displays inside virtual cockpits or at least 2D panels, and I know a few aircraft with HUD's that are very similar to displays already constructed. Why reinvent the wheel? It wouldn't be that difficult to make a callback for the HUD every rendering cycle (when neccessary) and render either directly to framebuffer or a texture (which the HUD code doesn't know, it just draws lines, rectangles, text, etc.) My own glass cockpit software does a similar thing with a few tricks. Every gauge file is a DLL (or a SO) containing only one callback routine which does nothing more than rendering the gauge with the given data. It doesn't know where you render it to (only its location in the viewport, which it needs for correct scaling and aspect) and it works great. IMO it works better than the pure OO approch that OpenGC uses, because you can distribute new features in binary form without needing a recompile every time. (Plug-in mechanism) Bit OT here but a small question: Has FlightGear for the Mac been built for Universal Binary already? I've got a brand new Core Duo Mac Mini here and I've tested it on another Intel box and it just crashes on startup. It ran on a G3 but it was pretty much a slideshow... If all else fails I'll try to make an OSX Intel-only build (since GCC comes standard with OSX) or just switch to the Win32 flavour, which runs fine on my Mini. - Take Surveys. Earn Cash.

I'm a very big fan of SketchUp and it's great for developing scenery, the only thing is that no-one has ever attempted to create a converter for Keyhole Markup Language (XML with a defined format) to a 'regular' model format like 3DS or Gmax.

Indeed, the idea of cutting FlightGear into modules is not a new one and has been floating around way before this nice new arcitecture paper came up that everybody takes as a reference. Using some sort of networked database is a nice start and definitely honours the idea of portability - yet I don't see such thing that is capable of handling data at a rate that meets the requirements of FlightGear. OpenLDAP as well as MySQL are very bad at handling a high rate of concurrent read/write requests - they miss the target by a huge distance, they both are faaar to complex (even MySQL :-) for such a task. Personally I think some thing like distributed shared memory might fill the gap. I've been doing some literature research on this topic several years ago, the idea looks pretty promising and different OpenSource implementations already have been around by that time - but I would not like to be the one to debug such a tricky beast :-) Cheers, Martin. One should not forget that FG has allready some networking capacity. This alone has allready allowed ppl to split fdm and rendering on several machines. Perhaps there is something to reuse here. Harald. Real-world flight simulation systems, as used in flight training devices, have been using this tactic for decades. A flight simulator as supplied by a commercial producer of training devices, has been split into a set of large functional blocks, each of them consisting of different modules: * Flight dynamics block -- consists of a set of systems that handle everything related to the aircraft's aerodynamic profile and the forces acting upon it. It does know nothing about scenery (aside from terrain elevation data, to detect ground movement), and knows nothing about the aircraft's systems. The only thing it knows about the aircraft is basically a 3D model with aerodynamic description, the position of the A/C's control surfaces and other extensions (landing gear, doors, spoilers), and the user-induced forces on the aircraft (engine thrust). It does a very good job at handling flight dynamics, and is fitted with a heavy CPU. Mathematical power is more important here than memory. * Systems block -- keeps track of everything happening inside the aircraft. From the engines to the air conditioning, everything that can't be connected as real avionics is simulated inside this unit. Most of the aircraft-specific descriptions are found here. * Visual system -- The visual system only needs to receive position and orientation data, and possibly the first and second derivative of it. From that it renders the (usually multichannel) outside view for projection onto the simulator's front screen. All of the scenery data is stored here. These three functional big blocks communicate over a high-speed network. Mostly, the units are built in dual-redundant sets to cope with eventual failure. Most of the cockpit systems in a real simulator consist of real avionics. ARINC buses connect the real aircraft avionics (like the FMC, RMU's, and most of the display systems) to the simulator as if they connected to an actual aircraft. The simulator's systems block takes the place of the aircraft's IRS, GNS, ADC, VOR and other navigation systems. Splitting up FlightGear into multiple functional units is something I'm really voting for. Especially, when you use a well-defined interface for every module. That way you can create a plugin-driven system that is easily extended upon, and could easily be split up physically using multiple machines across a network. I'm more into developing glass cockpits myself, but I'm also interested in creating a complete full-mission flight simulation suite. Especially since that would attract commercial funders (aviation industry companies like CAE, FlightSafety and Boeing) and possibly achieve FAA certification. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Re: [Flightgear-devel] Serious simmer
Ampere K. Hardraade schreef: I have seen far more serious simmers. :P Ampere That basically translates as: We really want some pictures of that! All of that guy's sim is MSFS-based with third party add-on instruments, and all of the monitors on his desk are run from a single PC. If FG is going to be used in home cockpits (Which I REALLY am in favor of) we need some way to get the instruments currently in FG out in an external application, which can run a 2D panel on a separate monitor. FG of course already has the possibility of exporting data over the network and linking copies for visuals (--external-fdm) but I'm not sure to what extent all of the instruments will follow in the slaved FG copy. The most important instrument you will have to run offboard except the basic six are engine gauges, radio and possibly map navigation. Making a decent (preferably OpenGL, vector-based) framework for FG panels would be a good development step, and it need not neccesarily be in the FG branch. As long as it follows the FG spec for the current instruments it will work, and we might be able to add XML-based vector artwork for glass cockpits later (SVG instrument rendering, anyone?). We could borrow some ideas from ARINC661 here. The project would be similar to X-Panel, already developed for X-Plane, so PanelGear might be a suitable name? - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Flightgear-devel] Serious simmer
AJ MacLeod schreef: Your original issue was, I think, a desire to have different parts of the FG 3d environment (including instruments) displayed on different screens, on a PC with multiple graphics cards and monitors. As far as I can see, it's already possible, with no extra coding, even for fully 3d cockpits. You can already set your viewpoint(s) anywhere relative to the a/c, facing any direction at any zoom level. You can have multiple views of any part of the same aircraft. Of course it should be even simpler now that we're using OSG... there was some mention in a thread in June (Impressions from LinuxTag) of using four osgViewer cameras configured in preferences.xml to output displays from one instance of FG. Mind you, I haven't seen the promised instructions materialise... it would be nice to see those - did they get onto the wiki when I wasn't looking? The one instrumentation-related thing that we definitely lack at the moment is a really flexible method of implementing glass cockpit displays within FG. Fortunately, it's not something that affects the type of aircraft I'm most interested in ;-) Cheers, AJ No, my original issue was to make external instrumentation possible over the network, not on a single PC with 6 monitors on it. Distribute the computing power, allowing more processing power for the flight dynamics and visuals and a flexible instrument setup. Take a real simulator as an example: The flight dynamics are run from a system that does only that -- flight dynamics. Pure math that is, and it's mostly done as a double redundant unit instead of a single one. The only data the FDM machine will output is that relevant to flight dynamics. That's basically all of the position data and 2 levels of derivatives of it (thus including forces on the airframe). Other systems, mostly composed of real-world avionics, pick up on that data and generate the relevant instrumentation, either as an image or as a control signal for a real aircraft instrument. Mind you, most flight deck builders, including the FS200x users, do not use a single machine for all the work. More and more of FS is ripped out of the FS logic, leaving only the raw FDM and visual data up to that system. All of the system logic is done outboard communicating with FS over a network link. The only downside of this, is that FS panels themselves are defined in gauges (DLL files) which can never be used outboard because of Microsoft's closed API. There are some really good payware aircraft on the market with tremendous levels of realism, but they are all limited to that one system running FS, so they are not suitable for cockpit builders. Mind you, most of my ideas ARE targeted at glass cockpits, which are mostly composed of vector based graphics. (Historically, aircraft even had vector-driven CRT's before the flat panel era.) If glass cockpits are built up of bitmap-based graphic material, it will look ugly and unrealistic. The Citation in FG, for example, has a very clear and visible display for the PFD/ND, but you can immediately see that it doesn't look like glass. Most cockpit builders will want 2D displays since most of it is hidden behind paneling. Only a few display elements are revealed, and these should look like they belong there. You don't want to be looking 'through' the display glass at some piece of 3D cockpit, you will want to be looking AT the display glass because it is part of the cockpit hardware. Everything will have to look flat. My ultimate goal is to model a flight deck after the professional sims -- each part of the simulator is dedicated to a system. This adds both redundancy and flexibility -- if a system crashes, it doesn't take the entire simulator with it as is the case with FS2004 based setups. The data exchange doesn't stop, because it isn't tied to a single 'master' unit -- if one unit should cease to respond (function), the rest of the system is notified and possibly another unit or a hot standby might take over. Likewise, if another aircraft is being simulated, the only thing that needs to change (in principle) is the system logic and flight model, instead of needing a hard simulator reset. My proposal for the project would be to create a working framework for 2D instruments, suitable for cockpit builders. The system would be similar, if not identical in functionality, to X-Panel for X-Plane users (I would like to give you a URL but some fool took down the X-Panel pages, every Google hit turns 404), which allows X-Plane instruments to be displayed on a different system (or multiple). As for glass cockpits go, an example is either OpenGC or Project Magenta, but both of these have the design of their displays hard-coded, what I would really like to see is that GC or steam panels could be designed in a WYSIWYG graphics environment, and interactive script added later. SVG has specifications for that.

I think this is already possible within flightgear now. The only missing feature (if I remember correctly), is the switching off of the 3D-rendering of the surrounding, which is not necessary when rendering a panel only. But this should not be a big problem at all. As a ugly hack just use an empty scenery on the panel rendering machines. Will network-linking of FG sessions synchronise ALL of the aircraft's property data, thus also syncing radio, instrument and cockpit data? For the visuals, only the basic 6DOF are needed, but is there also a way to keep everything inside the A/C's panels up to date all the time? That would get us a good start. Switch off the 3D rendering (as per Curt's instruction) and get 2D panels on the panel rendering machines. But we are going to need some good 2D panels, aside from the 3D cockpits already out there. Redundant FDM's is not a really neccessary step yet. I know that on some professional sims, all of the data is exchanged through a 'push' mechanism instead of a pull-style one. If one functional unit were to be stop sending data, the standby will immediately take over, as it was already receiving and processing data meant for the FDM system (it was only not transmitting data back). - This SF.net email is sponsored by: Microsoft Defy all challenges.

Aerotro You don't actually need to *fly* an aircraft to generate images. In an application like MATLAB, or possibly Lightwave or 3DS it would be possible to generate a parametric flight path (just a series of coordinates). FG will just follow those coordinates in a slaved mode, reducing it to a mere 3D real-time rendering engine. You won't be actually flying the aircraft, but the viewers won't see a difference as the A/C would have been flying on autopilot anyway. Regarding video caps, what are you using? Fraps is a good application which can capture any rendered screen in HD resolution, the cheap hardware-level but fool-proof alternative is using a TV capture card with the rendered displays on a VGA card's TV-out. The advantage of this is that the capture won't neccesarily go wrong if there's something wrong on the box running FlightGear, the downside is that you're stuck on PAL resolution (or NTSC, whatever you want these days. I'd recommend PAL ;)) - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Flightgear-devel] Glass cockpit and external gauges.
Those TC-10's look pretty interesting as free-standing display units. The displays on the Pilatus look like either Garmin G-1000 (with custom options) or Honeywell Primus EPIC displays, the G1000 displays are exactly 10 diagonal. You might have to fiddle a bit with the Line Select Keys along the edges. The enormous variety in current glass flight decks means we really need to think of a new way of defining glass cockpit layouts. Currently, most instrumentation is hard-coded and the binary only provides full displays (like in Project Magenta or OpenGC). You may be able to move the displays around, but not the individual elements (widgets) inside the displays. Why not make either an XML-based or a byte code based layout definition (like ARINC661) which allows more flexibility in the creation of GC displays, as the layout is defined in data, not program code, and can be changed run-time. Especially with modern aircraft this might end up being very useful.

I do think there aren't enough decent airliners in the FG branch, which
may be putting off current MSFS users because of the lack of accurate
airliner sims (like the Level-D 767-300ER or PMDG 737-800). FG does
provide enough opportunities to do system simulation through Nasal

Re: [Flightgear-devel] Multiple channel autopilot controllers
LeeE wrote: This is just for info and probably mainly directed at Roy Vegard Ovesen but it might also interest other people interested in setting up autopilot systems. As I've mentioned previously, I've had some problems tuning PID controllers, specifically controllers that maintain a specified pitch i.e. input is a target pitch and the output is an elevator-trim deflection. The problem is that the controller needs to be fairly 'brutal' in it's control at low speeds during take-off, to initiate rotation and prevent over-rotation, but this brutality tends to lead to oscillation at higher speeds Not to be particularly picky, but: Real-world aviation doesn't use the autopilot for take-off, because of this very issue, which is present in real-world analog controllers as well. AP is only engaged at acceleration altitude, when the gear and flaps are up (clean). Using the AP for climbing out in an unclean configuration at a very low speed will require a high pitch reference and possibly induce stall. TO/GA is sometimes used, though, but the TO/GA setting is a fixed pitch reference, and only engaged after rotation, not on the runway. One of the main reasons for that is also that the pilots still have the ultimate control over the aircraft in case of an engine failure. The 'strength' versus 'instability' issue is inherent to PID control mechanisms, if you build a strong controller it will tend to oscillate and jitter in situations where small control inputs are required, because strong controllers are designed for large control changes. It's a classic duality dilemma in control engineering, and possibly the only way to compensate for it is to implement adaptive parameters to the control system (e.g. the 'strength' of the control laws reduce as the airspeed increases or the angle of attack reduces). - This SF.net email is sponsored by: Microsoft Defy all challenges.

There is no license that will ever state that any application that *communicates* with it (whether it be a TCP socket, file, or Unix socket) needs to adhere to that license as well, since that would pretty much be the ultimate enforcement of copyleft.

Re: [Flightgear-devel] FlightProSim advert on FaceBook
I am not sure whether the content *generated* by a GPL-licensed program (such as FlightGear generating screenshots) would have to be licensed under the GPL as well. To be honest, I doubt it, because a lot of GPL-licensed tools are used to generate copyrighted content, even including Hollywood movie blockbusters! Op 11-11-2010 17:46, Gijs de Rooy schreef: Hi all!

Nah, I just sent to Facebook an inquiry for copyright infringement :-) Content on the FlightGear wiki also falls under the GNU GPL license (as stated at the bottom of this page http://wiki.flightgear.org/index.php/File:A-6E.jpg), so does this A-6E image. I am not a lawyer, but I do know that a copy of the GNU GPL license should be attached to the images, which I cannot find at the FaceBook page That is a copyright infringement, right?

Re: [Flightgear-devel] Willfully violating Google Terms of Use
There is a big difference between republishing a printed work and using it for a derivative, such as deducting measurements from a (paper) map to make a computer model of the streets or buildings which are also represented on the map. First off, in the case of a direct republish, the map's publisher can isntantly recognize that somebody made an actual copy, and therefore, also prove it in court. In case of a building or airport modeled off a map, how is the original map-maker going to recognize that the runway (12000ft long) was actually derived from *his* map? Since we're effectively modeling the real world, just like a map would, a map maker will have a very hard time suing after derivative works, since HIS map is also a derivative off the (uncopyrighted) real world. Let alone prove in court that your airport model is plagiarizing off his maps -- obviously, because it looks like the real airport it's supposed to represent on both the map and in the scenery! The only thing a (paper) map maker would effectively be able to copyright is his specific representation of the world -- that map, and only that. Now a digital map may be a dffferent issue since it's easy to automatically harvest large amounts of geo-data off digital maps, recompile it and reuse it for commercial purposes.

Try it out, buy a printed, commercial map at your local bookstore, place a derivative of it onto your web page, ignore the cease-and-desist letter and wait until they sue you. Then try to tell court that you've been unaware of the terms of use at the moment when you bought the map. Happened to a lot of people - doesn't work.

I'd like to emphasize that willfully violating the terms of use of a map should always be considered as being illegal and therefore unwelcomed (particularly in FlightGear land), no matter wether the map-maker can actually prove in court or not. I hope you do realize that modeling scenery from a set of photographs is also violating copyright (under those same rules), namely that of the photographer? So strictly speaking, we would only be able to model buildings we see (and measure) with our own eyes. And even then, you're making a derivative work off something -- namely the creative work of the building's architect. (Before you ask, there have been cases over this, by the Belgian copyright authority trying to sue anyone who published photographs of Brussels' Atomium structure, claiming a derivative work off the copyrighted design of the architect.) -- Try before you buy = See our experts in action!

Op 12-3-2012 15:26, Martin Spott schreef: That's an interesting case and we probably had a similar one recently in Germany. Did they try to sue anyone who *published* these photographs (on their private Picasa/Flickr/Panoramio or other albums) or just those who *sold* photographs ? Cheers, Martin. They actually tried to sue anyone who published photographs of the Atomium, either on their personal blog or on album accounts. Probably through some kind of automated crawler script which was programmed to send angry letters to anyone who posted a similar looking photograph. Needless to say, most of it is pure FUD, but unfortunately, civilians don't have the legal means to defend themselves against the enormous amounts of leverage big copyright holders can throw at it. -- Try before you buy = See our experts in action!
