Does anybody know offhand how much trouble it would be for our source code to have all loaders of aircraft files go through a library that understands what a relative URL is? If we can cut that over, anybody can develop and host an airplane simply by sticking some static files on the web somewhere. Which can reference components of other airplanes. This is 'doable, but quite a bit of work'. What' I've been idly hacking up is a helper tool/library that would process aircraft catalogs (basically the first part of the -set.xml files, slurped together into one or several files, with the aircraft id, metatadata fields, thumbnail URL, a download URL, and an MD5 sum), and use that info to download aircraft from 'a backend' - the default backend being .zips on a HTTP server, but with the option to support an SVN repo, Git URL or whatever if the backend can be glued in. (So you'd have a stable version of the 744 pointing at an HTTP server, and a separate entry in the catalog, with a 'development' metadata flag set, pointing at the live Git repo, potentially - and could switch between them) (If the catalog entries encode the min- and max- compatible flightgear versions for a particular aircraft variant, this also gives us a way to keep the '2.0.0 compatible' archives available for legacy users, which I am sure they would appreciated) The tool code then does the work of fetching updated catalog XML files (eg, daily), and checking for updated version of aircraft, supporting multiple concurrent variants of aircraft, and crucially, placing the extracted/downloaded zip/Git repo in a place fgfs can find it. The reason I'm building this as a library/command line tool is, obviously the various GUI launchers might want to use it, but as Vivian pointed out, there are good reasons to be able to download/manage from inside FG - as was just proved with terrasync :) It *is* possible to go to the next step, and keep the .zip files as compressed blobs, like Java .jar files - but that means a lot more FG hacking to get the OSG file loaders and other places we load files, using a different stream backend. Entirely possible, but I'd sooner establish the core concept - aircraft are pulled as blobs from HTTP - before worrying about the niceties. Code wise, I have about 30% of this prototyped - but not at a point where it can be tested. Since it appears to be a hot topic, I am thinking i should revisit it for 2.5 :) James -- All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.

Hence the discussion above. The main problem right now is that Git cannot cope with the size of the data, and it's getting worse by the day. The Git data repo on Gitorious is no longer fit for purpose as currently configured. I'm not trying to defend staying on single-Git, but I think the first step is to implement on-demand loading of individual aircraft (and dependencies) and prove that it works. Otherwise we'll be exposing end users to a lot of breakage. Once we can demand load reliably, breaking the repo into many pieces is relatively trivial. Streaming was mentioned (perhaps as a nice-to-have) in the context of Multiplayer. If you didn't have a particular model then it might be streamed instead of showing the rocket propelled blue and yellow glider. That's an excellent point, thank you. What I failed to mention was that some, but by no means all, models have a lighter weight version that resides in ~AI/Aircraft. Where it exists, it is this version that should be streamed for MP. Perhaps it ought to be the case for all models, but many aircraft developers never get around to it. Vivian -- All of the data generated in your IT infrastructure is seriously valuable. Why?

[Flightgear-devel] YASIM Issues- Contact Points / Tail Strike
Hello All... I am trying to better understand how YASIM calculates its contacts points 1) As from my experience, the SIM crashes when some part of the wings comes in contact with a building or ground and it does not crash if other parts of the wings hit the ground of a building.The wing specification is correct in FDM as checked againts the blender script. So how does it deduce the contact points? 2) Eventhough CG looks like it is in correct place, in YASIM, the plane do sink to the ground before take off. Insufficient lift maybe but the back of the fuselage do sink into the runway. As such, as possibility of implementing tail strikes? Much all appreciate all valuable replies and also if you could point me towards any valuable YASIM documents. -- All of the data generated in your IT infrastructure is seriously valuable. Why?

As a general rule I'd propose to make a clear distinction between a) datasets, b) hosting sites and c) protocols or revision control systems (at least). Some people are implying SVN when talking about hosting large datasets, others are implying Gitorious when talking about GIT.

No doubt I will feel foolish when it is pointed out that it is documented somewhere, but to date I have had to rely on experimentation and copying of XML/Nasal code from existing aircraft. 2. Is there any scaling, limiting or other filtering ? TIA Alan This was a much-discussed topic a few months ago. If I'm not mistaken, I think that the consensus was that the FDM should assume that it gets the raw signal from the joystick - even though there is some processing of the joystick hardware signal that is thought to be effectively unavoidable. Jon As was pointed out, the joystick, keyboard, mouse etc value is interpreted and processed by flightgear to become the properties in /controls/flight/(whatever). In general (there are exceptions) JSBSim.cxx copies those over to fcs/(whatever)-cmd-norm every flightgear frame. Every JSBSim frame the value from fcs/(whatever)-cmd-norm, where (whatever) is propulsion and gear controls, is moved to fcs/(whatever)-pos-norm then the JSBSim systems code runs which may or may not overwrite fcs/(whatever)-pos-norm with a calculated value. The the JSBSim autopilot code runs (different from the Flightgear autopilot). Finally the FCS section code runs. See FDM/JSBSim/models/FGFCS.cpp for details. JSBSim generally gets 4-8 frames for every FlightGear frame so that it runs at a consistent 120 frames/second.
