Re: [Flightgear-devel] Property Tree Question: How to save an aircraft specific property between sessions.
Hi Torsten, I looked at your seneca file, briefly, but didn't really find a way to translate this to the 777 sittuation. Being a complete nasal newbie, can I just add this function to any existing nasal script, or could I even put this code into a new file? Say I'm creating a new nasal file called acopsdata.nas containing: aircraft.data.add( /sim/dimensions/radius-m, /sim/dimensions/parkpos-offset-m, /sim/aircraft-class, /sim/aircraft-operator ); and copy that to the SenecaII nasal directory, would that interfere with your existing nasal code?

After some more experimentation, I found that I can save the property using userarchive=y, into autosave.xml. But using archive doesn't seem to work. My hypothesis is that userarchive save a property globally, whereas archive saves it into the local, aircraft specific (.fgfs/aircraft-data/777-200ER.xml) file. But,I couldn't find these properties anywhere. Incidentally, I did find a few interesting things. Taking /sim/aircraft-operaror as an example, I added: sim aircraft-operator userarchive=yNONE/aircraft-operator /sim to the 777-200ER-set.xml file, and added sim aircraft-operatorDAL/aircraft-operator /sim sim aircraft-operatorKLM/aircraft-operator /sim sim aircraft-operatorBAW/aircraft-operator /sim To the DAL, KLM, and BAW .xml fles in Models/Liveries, assuming that these would override the values of the already existing properties. However that's not what happens: This way the property value does not get saved, presumably because it destroys the original property object and replaces it with a new one that doesn't carry the userarchive flag. Is that correct? After adding the userarchive flag, to the properties in the Livery xml files, I found that they were saved again. Finally, I would be perfectly happy to just use the value stored in the livery xml file, but the problem here is that the aircraft model is only read AFTER the initial position has been calculated. At that point, the aircraft-operator property is still set to the default value of NONE, which essentially makes it useless. If there would be other ways to retrieve a property from the currently selected livery xml file that I would also be interested in hearing that. So close, yet so far away... cheers, Durk -- All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.

No it wouldn't interfere because it wouldn't get executed unless you explicitly add it to the *-set.xml's nasal section. Either as a link to a *.nas file or coded inline like this: nasal SomeOtherModule ... /SomeOtherModule MyModule script![CDATA[ aircraft.data.add( /sim/dimensions/radius-m, /sim/dimensions/parkpos-offset-m, /sim/aircraft-class, /sim/aircraft-operator ); ]]/script /MyModule /nasal To add this globally for all aircraft, probably $FGDATA/Nasal/aircraft.nas would be a good place for this code.

Re: [Flightgear-devel] Mapping Airspace
This is somewhat off-topic to FlightGear, so I apologize - but I respond to John Denker: Having looked over what you are trying to do, I strongly recommend using QGIS with the GRASS plugin. Very rarely do I use any of GRASS' built-in visualization programs - and very rarely do I use any of QGIS' built-in geospatial functions - but QGIS is the best program I've found to visualize GRASS data at the moment (with the possible, rare, exception of NVIZ). In fact, I believe the whole GRASS d.mon was rewritten as of GRASS 7 and now works differently (and hopefully better). I think most of the GRASS display functions were very, very old.

The reasons why I did it this way were: properties should be add-able from Nasal (setting property flags wasn't possible back then), introducing a new flag didn't seem desirable (simgear was still considered a generic library, much more than it seems to be nowadays), scanning the whole tree for just a few flags seemed undesirable, doing it in pure Nasal a quick and easy solution, and only very few aircraft needed it. Nowadays I'd probably go for proper flags. Ideally, their XML names shouldn't be hard-coded in simgear, but settable at initialization time. aircraft.data.add() could then be changed to just set that flag (props.Node.setAttribute(...)). m. -- All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.

However, the threshold number seems to depend on - the object(s) loaded - CPU load: If I have another process running (mplayer, for example) which consumes some CPU, FG now also hangs for the 3100 objects case (which would otherwise load fine if there was no other demanding process).

Re: [Flightgear-devel] Mapping Airspace
11: RC Pilot. Stays under 400' AGL and outside a 3 mile radius from any airport. Probably flying at a club site and doesn't care about air spaces. Has no way to estimate if he's over or under 400' AGL and probably is flying a plane that can climb 500' per second and hover at 2 clicks of throttle. Is annoyed when a VIP flies into the big airport 30 miles away and his club field is just barely inside the TFR radius and he can't even go out there and fly a paper airplane for several hours. 14: Drone Pilot. Still waiting for the official regulations in the USA (I think.) Realizing if manned aviation was just invented this week, the FAA would completely disallow it for safety reasons. In the USA you can do whatever you want in military airspace assuming you have proper permission to be there. We've flown at Schofield barracks in HI, in a navy operations area north of Oahu (entirely over water the entire flight including launch and recovery), at camp ripley (MN). Hopefully later this fall up in AK, etc. That seems to be the path of least resistance ... get permission to fly in military airspace and the FAA is entirely out of the picture. Or you can push through paperwork with the FAA to get a COA (certificate of authorization) which is permission to operate in a specific area at specific times with whatever specific other constraints the FAA wants to impose. When we were flying under a COA in the north pacific (1000nm north of Hawaii) we had to put a call out for any local traffic before launch and monitor some random frequency that FAA told us to monitor ... which was kind of dumb because how many Cessna's are going to be flying 1000nm away from the closest land? Of those, how many are going to be flying under 500' altitude? And of those, how many would be chatting on the random frequency the FAA picked for us?

[Flightgear-devel] terragear-cs apt.dat 850 runway support
Hi there, i just want to announce that I added support for the 850 apt.dat runways to genapts. This work is thought as a compliment to the currently ongoing development towards curved taxiways. The current state is that genapts reads runways and creates them accordingly. Features: -different designations for both runway ends -different runway markings for both ends -all kinds of lights (different where possible in the 850 format) I was very glad to find already existing definitions for all kinds of new approach lights in the source. Also, the possibility to assign different runway markings to both ends make it possible to finally create runways visually correct that are only used into one direction (RW 18/36 in EDDF is one example). I'm currently working on the missing objects like PAPIs/VASIs. As this is my first programming project, I hope I didn't mess up something too bad. The source is available here: https://gitorious.org/papillon81/terragear-cs/commits/850 I cleaned up quite a bit of the runway markings code and made it more flexible. So it should be easier to add a wider variety of runway types in the future.

Very rarely do I use any of GRASS' built-in visualization programs - and very rarely do I use any of QGIS' built-in geospatial functions - but QGIS is the best program I've found to visualize GRASS data at the moment (with the possible, rare, exception of NVIZ). In fact, I believe the whole GRASS d.mon was rewritten as of GRASS 7 and now works differently (and hopefully better). I think most of the GRASS display functions were very, very old. Yes, that helps. Thanks for the clue. One nice thing about GRASS is that it is very modular. In particular its backend computational features are independent of its frontend visualization features. The QGIS frontend graphics are orders of magnitude faster than the GRASS frontend graphics. Also QGIS has a feature called recompute CRS on the fly that simplifies a lot of things. It's nice to see a little bit of sanity in the world. Here are some questions you might be able to help me with, if you would be so kind. Off-list answers would be fine, although I suspect I'm not the only person who is interested: 1) GRASS has a drape feature implemented by d.his that sets the intensity from one raster and the hue from from another, which is a very nice way of combining slope information and elevation information into one image. It's not obvious how to achieve the drape effect in QGIS ... with or without involving GRASS. What's the trick? 2) GRASS has a catlist feature implemented by d.rast that makes it easy to display only a certain range of values, e.g. everything from 3000 feet on up. This is particularly slick in conjunction with item (1) above. I can always do this with r.mapcalc, but I was wondering if there might be a convenient way to do it on-the-fly. 3) I suspect that doing reprojections on the the fly only works for vector data. I tried it with raster data, expecting to see either a resulting image or an error message, but saw neither.

Hi Geoff, thanks for testing! Indeed, I forgot the texture, sorry about that.

Hi Jon! I've seen something similar before, it's incredibly annoying, and I suspect you'll eventually track it down to a typo in an stg file.

Here, with AMD 605e 2.3GHz, it hangs at around 5800 objects, with the
CPU behaviour you described. Going slightly higher, from around 6000,
FG starts to burn CPU again, but nevertheless won't get any result.
Looking into the problem, seems the scenery is loaded eventually, but
the fdm is not initialized so this check never passes:
if (globals-get_tile_mgr()-isSceneryLoaded()
fgGetBool(sim/fdm-initialized)) {
Now, the FDM init code has this:
if (globals-get_scenery()-scenery_available(geod, range)) {
SG_LOG(SG_FLIGHT, SG_INFO, Scenery loaded, will init FDM);
That in turn ends up at:
simgear::CheckSceneryVisitor csnv(getPagerSingleton(), toOsg(p),
range_m, framestamp);
// currently the PagedLODs will not be loaded by the DatabasePager
// while the splashscreen is there, so CheckSceneryVisitor force-loads
// missing objects in the main thread
get_scene_graph()-accept(csnv);
if(!csnv.isLoaded())
Finally we arrive at:
void SGPagedLOD::forceLoad(osgDB::DatabasePager *dbp, FrameStamp* framestamp,
NodePath path)
{
//SG_LOG(SG_GENERAL, SG_ALERT, SGPagedLOD::forceLoad(
//getFileName(getNumChildren()) ));
And now the crazy part! If I uncomment this logging, everything
suddenly works, even with 20k objects:

Re: [Flightgear-devel] Mapping Airspace
John:
Admittedly I work with GRASS solely on the text-based side - rarely if ever
touching the GUI - but hopefully I can help:
1) To be honest, it's probably easiest to continue to use d.his and then
display the resulting map using the GRASS plugin - QGIS doesn't really have
many (if any?) raster tools, while GRASS was created primarily to deal with
raster features (and added vectors later).
2) I believe r.mapcalc is the way to do this on the fly - not sure what you are
asking, because I'm sure d.rast calls this on the fly when you go to display
the image?
You can always do something like
r.mapcalc {$output_map} = if({$input_map[0,0]} = 3000, {$input_map[0,0]},
null())
so it doesn't stop the processing.
3. You CAN do raster reprojection on the fly. However, your results won't be
anywhere near as clean as a vector reprojection as a result of the different
format type. Also, there are some rules - I believe the projection has to be in
the current region of the location you're reprojecting to, and also the
resolution must be sufficient in order to handle the map.
The r.proj part of the manual has two good procedures for doing so:
http://grass.osgeo.org/grass64/manuals/html64_user/r.proj.html
(old version but should still be okay)
4) I think it's an actual limitation - I am assuming, for a categorical map,
you would like say all cats 10 to have a transparency but all cats = 10 to
not have a transparency? I'm not sure how to do this, if this exists - I'd just
use r.mapcalc and display two different layers.
I hope I didn't misinterpret what you're writing, and hopefully that was of
some help.
Cheers
John

[Flightgear-devel] Any alpha testers with a bit of extra time on their hands?
I have something here that I think is kind of fun. I've been fiddling with this off and on since last fall and decided it was time to clean it up a bit and quit hording all the fun for myself. Basically I have taken the F-14b and created a high performance Navy drone out of it. It can auto-launch from a carrier, auto fly a route (if you've input one) and can do circle holds (compensating for wind.) I've added a simulated gyro stabilized camera that will point at anything you click on and then hold that view steady no matter what the airplane does (similar to what real uav's can do.) Finally, you can command it to return home and it will find the carrier, setup a reasonable approach and nail the landing perfectly every time (factoring in wind, carrier speed, etc.) I put together a quick web page that includes more of an explanation and description of what the demo does. I have a link to a zip file you need to download. This must be extracted over the top of the existing f-14b as per the installation instructions on the following web site: http://www.flightgear.org/uas-demo/ I'm hoping to get a few people that would like to try this and report back on a couple things: - were you able to get it to work? Were there any missing files or major blunders in the .zip file package? - are there places where my web page instructions stink, and can you help me write better or more accurate instructions, especially for the Mac - I already know my instructions for setting up the vinson demo aren't good, but it's been so long since I tried to do this on windows I forget all the fgrun details. Maybe there is an easier way now? - finally, what do you think? general impressions? things you thought were especially cool, or especially stupid? You probably can think of a dozen feature requests, and I have some things in the pipeline already. (For instance I have a refueling mode that is currently disabled, but almost is close to working. And I've done some preliminary work on adapting all of the auto-land logic for runway landings.) - if you happen to go look at the nasal code that does all the magic, please don't judge me (quoting Eskeletor from nacho libre) -- that was actually a fun sub-project (for a former computer scientist.) :-) - Oh, and eventually I'd like to add pictures to the instructions. If you happen to catch an especially cool looking view (weather, clouds, time of day, sun, sun glint, scene composition, etc.) then please feel free to send me a picture or two (or even a youtube movie) so I can make the instructions prettier and more exciting. :-) If I can get this demo all cleaned up and generally running pretty well, I have another UAS demo that is similar, but centered around the ATI Resolution-3 airframe (which is a 92 2.33m composite marinized flying wing.) Then if that all goes well, I have actual embedded C code to do much of these same sorts of things that can run on a gumstix embedded computer (or similar.) This code is able to talk directly to flightgear via udp packets, and has actually flown in a couple different UAV airframes using real sensors and real actuators. So you might see a progression developing here from pure simulation with all the logic prototyped in nasal, to software in the loop running pure C/C++ code, to the same software running on actual embedded hardware (using FlightGear as reality), to the end result of an actual real life UAV. (And I've been using drone, UAS, and UAV pretty interchangeably here.) Thanks!
