Re: [Flightgear-devel] Final (?) 3D clouds patch
Hi, Hi All, Attached is what I'm hoping will be the final 3D clouds patch. It does the following: - Replaces simple shader attributes with vectors (this was missed out of the last patch by mistake) - Includes Yon's Fog update code (Thanks!) - Fixes a bug since 1.0 where --enable-real-weather-fetch stopped the other weather scenarios from working. Let me know of any bugs. -Stuart Thanks for all your work, Yon and Stuart! The clouds looking great now- the order problem is 99% solved so much as I can see! I see only some few problems still: -against a second 3d-clouds layer, the problem with z-drawing appears again -setting thunderstorm: the clouds has this transparency problem again, perfomance is weak, no lightning and thunder back (o.k. missing feature) maybe (just an idea) we can create a special set of a thunderstorm which is loaded instead the usual set which seems to be changed for fitting. -ns and st-layers covers now full, but also decrease dramatically the fps. Even on my fast machine I only get around 8-12fps- not usuable! Maybe it helps a bit if we couple the cloud visibility range with the generell visibility. Or we should use of the old, 2d-layers instead! Cheers HHS -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada. The future of the web can't happen without you.

Hi, B1900d : Very complete Commuter jet, Twin Turbo Prop. - No comments received Yep- should be in the package c17p: Light Single GA; our default aircraft - overall size can possibly be reduced by removing some liveries O.k.- and where to store the liveries which didn't get into the base package? There was a lot of work- it shoulden't be lost. dhc2: Versatile Tail Dagger, with Aerotowing Capability - Current version is rather tricky to start up. Maybe change with one of the other nice Dehavilland models by Syd Adams? [DT] No- I think the dhc2 is easy to start and beginners will like it to play with the switches to start th ac!

The Thuderstorm scenario has a very specific METAR. We could easily change this to something that looks better.

This is very easy to do : The 3D cloud code defaults to a 2D layer if it can't find an appropriate cloud definition in the cloudlayers.xml file. So, you can simple remove the st and ns sections from cloudlayers.xml. If you agree, I'll look at doing that tonight. This may also help with the Thunderstorm scenario. -Stuart -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada. The future of the web can't happen without you.

[Flightgear-devel] GPS refactoring
Here's a patch which refactors the 'plain' GPS code into a slightly more manageable structure - i.e breaks the large update() method into various sub-functions. I've tested the patch with B1900d, and things seem to work as expected, but if anyone experiences GPS weirdness after this is committed, of course please report it. The motivation for this was helping me learn the code - I've planning some changes in this area, and splitting up the logic will hopefully make that task easier. The patch is too large for the mailing list limit, since it moves virtually all the code around. Instead I've uploaded it here: http://files.goneabitbursar.com/gps.patch Regards, James -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.

Hi Gerard,
Could you tell which aircraft you see these problems with? There might be
other problems lurking in the code.
This one wasn't easy to find - my manual CVS bisect search on
JSBSim/CVS put me on the wrong track (I'm not sure what when wrong there).
In any case I got the same valgrind complaints for the whole period I
tested, Aug 1st to now, but NaN problems only from Dec 1st with my test
case (the Dec 1st commit seems to be a completely unrelated and is not
even present in FG yet). I finally found the missing initialization by dumb
luck while checking up on all -Wall warnings in JSBSim (not that many).
The warning wasn't related to the initialization issue.
Valgrind wasn't very helpful in tracking down the source of the
uninitialized values this time, what I got was messages like this:
==11005== Conditional jump or move depends on uninitialised value(s)
==11005==at 0x8152E72:
JSBSim::FGQuaternion::ComputeDerivedUnconditional() const
(FGQuaternion.cpp:164)
==11005==by 0x807BA15: JSBSim::FGAuxiliary::Run() (FGQuaternion.h:461)
==11005==by 0x804FD2E: JSBSim::FGFDMExec::Run() (FGFDMExec.cpp:367)
==11005==by 0x804E341: main (JSBSim.cpp:360)
with no hint on how the value(s) got there in the first place..
Now JSBSim/CVS runs without any valgrind complaints here on my ZLT-NT
and Submarine Scout test cases.
But I just tried the 737_cruise_steady_turn.xml script and got complaints
again, will try to track them down.
Cheers,
Anders

[Flightgear-devel] GPS/FMS/route-manager changes
I'm planning various enhancements to the GPS and route manager code in the next few weeks and months, and would appreciate any feedback or criticism people might have, especially from people using the code in ways I might not have expected. In summary, I'm planning to make the route-manager more 'abstract', i.e remove the GPS-like functions it currently has (time to next waypoint), etc. At the same time I'll make the GPS a mandatory instrument, and change the GPS code to use the route manager waypoints. This should make the route-manager and GPS code usable in far more aircraft to drive a CDI/HSI gauge. I'm going to update the route-manger to have a 'current waypoint', and no longer pop waypoints once they are reached - instead the current waypoint will be incremented. This will enable the route-manager to drive the leg/flight-plan mode of the GPS more easily, and also permit me to show the active route on my work-in-progress NAV display. Once these basics are done I will extend the GPS with a Nasal interface and various standard things it's currently lacking - closest VOR tracking, and proper 'direct to' and 'nearest' modes. Once the above is done I plan to deprecate all of the existing DCLGPS code, and re-create the KLN89b as a generic 3D instrument using Nasal. I'm happy to work with anyone to create other GPS units - hopefully they will all be doable with a Nasal layer on top of the generic GPS code, and the Nasal interface can be extended as necessary to make this work. Assuming all the above is done, the next step will be adding even more functions to enable a real FMS to be created, again in Nasal with support functions in C++. I would appreciate help on the instrument side - I know Syd has created parts of the KLN90 for the B1900, and I'll keep that working and hopefully enhance it in parallel with the KLN89B work. The two seem to share an awful lot of functionality, so some Nasal reuse is probably possible as well. I've created a wiki page to track the things I'm currently working on: http://wiki.flightgear.org/index.php/Plan-zakalawe Regards, James -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.

Yes it is a guess, how many models here are drawn with a guess ? not only the landing gear :) Giving it a pitch of -3 deg is not so bad. Or extend more the nose gear which will be ugly. AND The question isn't it , only: Which is the less stupid :) to keep the model floating above the ground when not in air ? or to modify the offset ? which won't shock anybody using that FG Reference Model. Easy to do, giving the possibility, latter on, to update, if somebody is able to bring the right blueprint of that Aircraft ( same model, same equipment.). cheers Once you've aligned the reference point between the 3d model and the FDM model you should never have to add offsets to the 3d model; if there's a discrepancy it means that something is wrong. The best way, for modellers, is to make the landing gear in it's maximum extended position - the position it would be in without any weight upon it - and use those coordinates for the gear contact points in the FDM. Then you vary the gear spring and compression rates in the FDM so that the aircraft sits on the ground at the right height and attitude, and then finally adjust the model's gear compression animation so that the two match. That is right but only theory. That means, too, that you include an animation compression extension of the gear (which is not the case with that c172p). With it , yes, = a drawing (blue print detailed) which gives you the right position of the gear when extended + = the know how about the right values of the landing gear ( damping_coeff , spring_coeff, pos min pos max, ) + = the right weight and force applied , on each contact point, we can do the perfect Aircraft, with a perfect FDM regarding the landing gear reactions. Unfortunately it is very rare to have all of these informations, and in many case we must be pragmatic, and the less stupid (if possible). I remember when i did the F-8E , i had some very high detailed drawing, but nothing else regarding the landing gear, but the usual position on ground. In order to get it, in a correct position when it is in air fully extended, and to get it, retracted correctly in the box without cheating , i had to calculate the size and the geometry of each components , it was a lot of work :( I had the same difficulties with an other aircraft done for a friend (SU-34). While it's usually impossible to get exact data on what the height and attitude on the ground should be, with reference to photographs etc. it should be possible to get it correct to within an inch for small aircraft, and perhaps several inches for large aircraft. One of the checks that every modeller should do is to check the gear compression under different loads. This will amount to testing different fuel and passenger loadings, including asymmetric loadings. Military aircraft can also be checked with different weapon loads. Regardless of aircraft type though, once you've got it right the gear will sit on the ground whatever the loading, even with asymmetric loading. LeeE Cheers All of FG is only theory - it all takes place in your computer:) The C172P FDM includes spring and compression rates, not only for the main and nose gear, but also for the tail skid. Although the main gear is fixed in position it flexes and both this, and the nose gear compression, need to be modelled/animated if the gear wheels are to stay on the surface of the ground and not sink through it on touch-down, or rise above it during the take-off roll as the wings start to generate lift. This isn't difficult to do and doesn't need exact drawings or data to achieve an acceptable result. A bit of thought about the landing gear design and reference to lots of photos will give you a very good idea of the limits to the flex and movement, or oleo compression, in landing gear. Too much flexure in the fixed C172P main gear and they will break, and the oleo damper arms limit the maximum extension in the nose strut. Once you've established plausible limits to the gear flexure/extension it's just a question of putting in the time and effort to narrow

Hi, I had today a closer look into this issue. I got a drawing of the OM of a c172 which shows the the pitch angle with compressed nose gear. I tried to rotate the model but then I found something which shows me that the problem lies on the fdm: at cruise speed about 100kias I got a pitch about 0.3- 0.55 degres. Myself and some others in IRC-Chat noticed that the model is hardly to steer on the ground and lift of itself without touching the controls or the trim. I don't know, but could it be that the cg of the aircraft isn't right which makes all these? Attached the drawing from the OM.

I've created a wiki page to track the things I'm currently working on: Can't tell whether this is related, but I just noticed a problem with the b1900d's ILS localizer. I tried a little circuit: starting off at EHAM park position B01, taxied to runway 36L, made a 90 deg right, for about a minute, then a 180 right, until I hit the northsea coast, and then made a left to heading 220, approx, following the coast. Over airport Valkenburg (EHVB), I should have intercepted the ILS localizer for EHAM runway 06 (110.55, tuned on radio 1). But this didn't happen. Glideslope was okay.

Re: [Flightgear-devel] Final (?) 3D clouds patch
Curt wrote: I wonder if there is some sort of floating point resolution / rounding problem with the sort? I see a lot of flickering myself. Also if I look some particular direction and the clouds get sorted ok, then look away for even a second, and then look back (by changing the view direction) the clouds seem to have totally lost their previous correct sort and need to be sorted again ... but that doesn't happen until the clouds come back in view. I'm not sure what the sort criteria is, but it seems strange that the sort order would get messed up in a brief second of not having a particular set of clouds in view. One of the performance improvements introduced with the last patch is to re-use clouds rather than generating unique clouds for each position. This makes a significant performance difference on my system (about 5fps IIRC), but means that occasionally you end up between two instances of the same cloud, and the sprites need resorting as you change the view. You can avoid this by increasing the number of cloud types in the Rendering Options dialog, then toggling Enable 3D clouds to cause re-generation. At the moment the slider goes to 20, which minimizes the probability of hitting this issue. Obviously, we could increase the limit still further if required. -Stuart -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.

I thought I sent you an updated version for the rescue-over-MP

Anyway, the start of the load block should check for receiving the

print(S51 Initializing...);
var listeners = [];
var mpnode = cmdarg();
if (mpnode.getNode(sim/multiplay/generic) == nil) {
print(Generic MP properties not received, aborting);
return;

[Flightgear-devel] NAV display proof-of-concept
(finally, a post from me that actually shows something useful instead of shuffling around chunks of code! If it makes anyone feel better, this is more or less what I've been working up to since September) Two evening's hacking (and learning about OD-gauge and generally fighting OSG): http://files.goneabitbursar.com/nd-first-attempt.png That's a route from EGPH down to NEW, following the east coast of the UK to OTR, then turning east to head for EHAM. Range is currently set to 320NM. Diamonds are airports, hexagons are NDBs or VORs. Fixes are disabled because there's too many at that scale. (Everything else you can see is Syd's existing 777 NAV display, being able to hack up his existing instrument locally has made my life much easier, so huge thanks to Syd). There's many lessons to be learned from this, about rendering and anti- aliasing of vector primitives especially. Next steps are to try using point sprites (should fix the AA issues, and allow using real symbols), and replacing RTT with a simple sub-camera, since I am pretty sure the render-texture is not helping. (Clipping and z- ordering is probably easier with the render-texture though). I'm also going to try using an actual mesh for each symbol, with shared osg::Geometry and each icon placed using a osg::MatrixTransform. I worry about the performance of OSG scenes with (potentially) hundreds of nodes, though - is this fear mis-placed? Aside from the above there's all the obvious features - showing runways, including waypoint data, and so on. As might be guessed, this is several weeks away from being suitable to go into CVS. Comments appreciated, especially on the rendering - both making it efficient, and making it prettier. James -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.

Now, you will only get METAR if you have METAR as the scenario, as well as --enable-real-weather-fetch. -Stuart You were correct. I had not set the weather scenario to METAR. I ran fgfs once with 3D clouds and once w/o 3D clouds, both with real-weather-fetch and scenario METAR. I only got 1 fps with the 3D clouds. Earlier with 3D clouds, I got about 21 fps. Also for both 2D and 3D clouds, the field elevation is not accounted for in applying the cloud base MSL height. The METAR for these 2 runs showed broken at 011 (translates to 1,100 ft AGL) but leaving KDSM field elevation of 957 ft MSL, I was in the clouds by 1100 ft MSL or only about 150 ft AGL. Are we not applying the metar field elevation + metar AGL to get the cloud level? Dave P. -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.

[Flightgear-devel] [PATCH] update dialogs with parkpos
Hi!
Reacting to a feature request, attached patch adds support for
parkpos selection in the location on ground dialog, and clears any
parkpos preset in the airports dialog.
Somebody please review and commit.

[Flightgear-devel] C172P pitch at cruise
I agree with what Jon has said--the pitch angle with the aircraft on the ground should be 5 degrees. If this is modeled, I don't think there's any other significant issue. With regards to the pitch angle at cruise, I simply cannot see how you'd ever model that exactly. First of all, it is dependent upon several things: Airspeed, density altitude, aircraft loading and the general rigging of the aircraft, just to name a few. I have flown two nearly identical aircraft (both 172's) and can tell you that they each fly slightly differently--and the picture out the window is not exactly the same in both aircraft. Certainly the horizon intersects the side of the cowling (from the pilot's perspective) at about the same spot, but it isn't exact. And without looking at the XML properties for the 172P I cannot say; but where is the CG located for the current emulation? Is the aircraft modeled at maximum gross weight, or with only the pilot--and how heavy is the pilot? I am not trying to say that the picture out the window changes drastically with variations in loading, but it certainly *does* change somewhat. But more importantly however is that the control force required to maintain flight stability changes, as does the trim requiring to relieve those control forces. But if the emulation can be loaded in similar fashion to the real aircraft, with similar results (airspeed and power settings), then I submit that it's probably as close as you're ever going to get. The point here is that I do not believe there is any ONE right answer. If the emulation flies like the actual aircraft, then all is good. For example, if full throttle in the emulation gives the same approximate airspeed as in the real aircraft (about 115-120 knots, if memory serves); if a power setting of about 1900-2000rpm allows one to maintain an altitude of about 1500-2000 feet MSL at 90 knots; and if 1500-1600 RPM allows me to fly a 3-degree glideslope at about 90 knots with 10 degrees of flaps...then all is good. How much better can it get? (Having said this, I do think that the default 172P model in FG needs property value tweaks to increase realism; but that cannot be done to an accurate degree until a proper set of 3-axis flight controls are configured to the emulation. A joystick is simply not accurate enough to make the kinds of hair-splitting determinations we're talking about here, IMHO.) Incidentally, I did make contact with a friend that is sending me a copy of the entire set of drawings included in the 172P service manual. If they are of value and are of good quality, I will gladly scan them and post them for review. TB -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.

How much better can it get? I agree with the spirit here. There is definitely a range, an envelope of reasonable values, and as long as the model is within the envelope, it is neither necessary nor possible to find a single right answer. The pilot's perception of pitch, looking out the front window, will vary, depending on whether the seat is adjusted high or adjusted low. Also, the AoA (and therefore pitch) will vary by about 3 degrees, depending on whether we're talking about high-speed cruise at sea level or economy cruise at 12,000 feet. Pitch varies even more depending on flap setting. My point here is that most pilots, especially low-time private pilots, don't obsess over /absolute/ pitch numbers. They find a pitch angle that works under the circumstances, and just hold that. Delta pitch is more immediately relevant than absolute pitch. There /are/ ways of perceiving absolute pitch, and there are situations where a skilled pilot can put this to good use, but this is a rather advanced topic. We can discuss it if anybody is interested. All in all, therefore, getting the cruise pitch attitude right to the nearest degree or better would be nice, but it's about 20 or 30 places down on the list of things that need fixing. I've been saying for years that the FDM needs fixing. It needs fixing in ways that rotating the zero-reference of the model will not help. Not help at all. Here is one example among many: Consider the following scenario: standard atmosphere (ISA) 5000 feet full throttle 60 Kias == approximately Vx flaps retracted inclinometer ball centered In fgfs, I observe a small negative rate of climb, about 30 fpm down. This is the sort of thing real pilots notice. Does anybody want to claim that a real Cessna 172R will not climb at Vx at 5000 feet? How much better can it get? It can get a lot better than that. Also, just for fun, try a balked landing. In a real C172, set up for a short-field approach with full flaps, then start a go-around Do it at a safe altitude (at least 3000ft AGL) with a skilled instructor, so you don't kill yourself. Then try it in fgfs. Rather different, isn't it? On 12/07/2008 11:00 AM, Heiko Schulz wrote: We have reports from real c172 pilots that thy don't see any issues! I'd be surprised if anybody said the rate-of-climb behavior was not worth fixing, or that the go-around behavior was not worth fixing. -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
