Re: [Flightgear-devel] MP Liveries for Boeing 737-300

For a select few aircraft models which are very, very popular in the real world (including the 737 of course, but also the C172, 747, B1900, others in other "categories"?), I think it would be "fun" to include a larger number of liveries, so that users all across the globe can feel a sense of familiarity or identity with the aircraft, with which they may have had some real-world contact. For the less popular models I agree that just a few are more than sufficient. Of course, a model's popularity *within FG* should probably factor in there a little as well...?? Just musing... -R.

[Flightgear-devel] Terrain errors report
There are several huge and very unnatural walls in the Himalayas, both running NS and EW. I'll give the line of latitude or longitude that the wall runs along, and the end coordinates of the walls: (1) e86.250 (NS), from n27.875 to n28.000 The above wall is capped on the north by an east-west wall: n28.000 (EW), from e86.196 to e86.348 (2) Another wall is farther west: n28.625 (EW), from e83.250 to e83.500 The above wall seems to pick up again a bit farther east: n28.625 (EW), from e83.700 to e83.875 (3) And a final one: n28.750 (EW), from e83.375 to e83.500 There are also several large flat areas, for which I'll give an approximate centre point: (4) n28.550, e84.297 (5) n28.550, e83.830 (6) n28.670, e83.394 There are others too, but my guess is that whatever causes one of these anomolies probably causes them all.

[Flightgear-devel] is gimp sgi rgb handling broken or not?
Look at Models/Airport/fbo.rgb. OSG under valgrind, chokes on row #52. entry in the start offset table @0x02D0: 0x2200 entry in the length offset table @0x12D0: 0x0207, means last byte in row at 0x2200+0x0207-1=0x2406 data @0x2200: 0xFE means, copy 0x7E bytes, we got 0x007E pixels. next code @0x227F: 0xFE means, copy 0x7E bytes, we got 0x00FC pixels. next code @0x22FE: 0xFE means, copy 0x7E bytes, we got 0x017A pixels. next code @0x237D: 0xFE means, copy 0x7E bytes, we got 0x01F8 pixels. next code @0x23FC: 0x86 means, copy 0x06 bytes, we got 0x01FE pixels. next code @0x2403: 0x01 means, make 1 copy of next byte, we got 0x01FF pixels. next code @0x2405: 0x01 means, make 1 copy of next byte, we got 0x0200 pixels, scan line complete. next code @0x2407: 0x00 means end of scan line. *BUT* this is already 1 byte outside of the length! It isn't consistent, either. The length for the preceding row #51 includes the terminating zero in the count properly (start offset @02CC: 0x2CCC, length @0x12CC: 0x01EE, last byte according to table: 0x2CCC+0x01EE-1=0x2EB9, terminating zero indeed @0x2EB9) OSG loader notices the completed scan line (but not before attempting to read the next code), so normally no harm is done. The only possibility of a crash would be if the input buffer is at the very end of the heap, so reading the extra byte would result in a segfault.

I did not understood everything about the content of that topic, since the technical which is involved is "flying" over of my low know how. I would like only say ( again , because said before) that the coastline which is close to my favorite area , the French coastline on Mediterranean sea, was better with the 9.8 scenery. It is sure that the last version is mostly better than the 1.0, however it is not so right than it was with the old 9.8 version. I understand that making the scenery is a very difficult work. From the data which which are freely available it is difficult to get the same quality that we can have now with google 3D or IGN (France). In addition to it, i worry that we are not able to get the right connection from the generic sea tile to the coastline tile ( difference of level) So, before to spend some time to try to develop any water shader, it would be better to invest time to try to get a consistent sea surface.

To the current state we have a coastline around each 'isolated' continent or island which is either made from a single closed polygon (which could be GSHHS) or from the outline around a couple of adjacent polygons (VMap0 political boundaries). To get an overview, please check here: http://wiki.osgeo.org/wiki/Geodata_Repository#PostGIS_serving_vector_data This coastline is the basic factor for a simple principle: Everything inside this coastline is counted as ground, the entire area outside the coastline is "Ocean". The same principle applies to lakes - just in the reverse order: Everything inside the lake shoreline is water. So, even if our STRM elevation grid would indicate some sort of elevated ground outside our coastline, it's going to get clipped out due to the given principle. In contrast, if there's no elevation data for an area inside the coastline, then the ground is still going to get extended in accordance with the coastline but at sea level. There's a nice example for these corner cases if you approach RWY 24 at TNCE in the 1.0.1 Scenery. I'm proposing a similar but somehow opposing schema (talking is cheap ;-) Let us have the seabed modelled using bathymetry data, clipped against the same coastline which we're using to clip the ground elevation, limit the maximum 'elevation' of the seabed to the elevation of the respective coastline, which is presumably at MSL for all ocean shorelines - or the individual elevation of the respective lake. Probably limit the seabed elevation to a few centimetres below to allow for some nice waves I don't see any reason why and how this approach would set KSFO under water. > Also, is global (even crude) coastal bathymetry data available?

Someone has to feel responsible for managing this site, ensuring that the liveries are consistent with the corresponding aircraft either from CVS, from the official aircraft download page or from both sources. According to my personal experience with getting "administrative workflows" introduced into the FlightGear project I'm uncertain wether such an attempt is going to pass along without major difficulties. Simply check the size of the different aircraft directories and compare that to the size of the livery package as proposed by Gijs - I doubt that the required overhead is worth the trouble. The CVS (or whichever) repository serves well as an 'authoritative' home for add-ons like these liveries - because users will complain early when things break. Once you start spreading these add-ons over too many different places, you're going to face what I'd call a maintenance hell because everyone is going to create his private spin-off Just look how fast this "UnitedFreeWorld" site turned into a site where people drop their garbage - and forget about it.

But I think it's a rather bad idea. First, because lagging and freezing is already bad for loading aircraft from the local disk. Loading 3 MB textures over network while flying won't make that better. And then, I suspect that most of these textures would be (rather infantile) "personalized" liveries. Then you get 737 with skulls and bones logos and all such "cool" things. Or swastikas.

I also think that AIrcraft should be separated from the base data in CVS. At present the CVS data repository is huge, and most of that size is due to the number of aircraft we have. Checking out a new copy of the data currently takes hours, and is only going to take long as the number of aircraft inevitably increase. Splitting out a new Aircraft repository would also allow us to relax our CVS commit policy - so aircraft developers would have CVS commit rights for their own aircraft. Of course, there will be some pain involved, but I think we're going to have to do this at some point, and the sooner we do it, the easier it will be. -Stuart -- This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel

Hi, I've collected 26 liveries, put them in one file and added the livery selection dialog.

I think there are at least three issues on the table: a) Apparent temporal wander (d/dt) [called "diurnal" above] b) Apparent transport wander (d/dφ) c) Actual erratic drift. > The purpose of implementing the drift in FlightGear is for operational > realism, more than scientific accuracy, and therefore the drift value > is designed to make the gyro compass be inaccurate if the light > aircraft pilot does not reset it regularly. That's mostly about talking about item (c). Actually, in the existing code, the drift rate is carefully calculated to be equal to the earth's rotation rate. It's not some wild guess that "5 degrees every 20 minutes is about right". The hypothesis that it is a buggy attempt to account for temporal wander is very much alive. Meanwhile, there is no attempt to model transport wander, as you can verify by looking at the code and/or by flying over the pole. If you want to fly the stock c172p this time of year, I suggest flying over the _south_ pole since there are still no interior lights or instruments lights in the c172p. If you fly over the pole, the heading indicator card spins 180 degrees in a fraction of a second. It's hilarious. > If you want to include > the sin(lat) term, be sure to add a flag so we can distinguish between > the laser and mechanical variants. a) It would be easier -- and much better -- to include the sin(lat) term and then to include a latitude-nut property which could be set appropriately. Then anyone who wanted to null out the (d/dt) term could do so ... and could also properly model the effects of taking the aircraft away from its native clime. b) As for transport wander, rather than keeping track of the "heading" of the gyro, as is done now, it would be much nicer to keep track of the physics. I'm hoping this would be pretty easy. Keep track of the gyro axis as a vector in x,y,z space, and project it on to the axes of the aircraft, and voilà! Can some FDM guru tell me how to obtain the quaternions and/or the vectors that specify aircraft orientation? I see lots of examples where instruments etc. refer to the Euler angles (yaw, pitch, and roll) but not much in the way of quaternions or vectors. I found some code in Main/viewer.cxx that constructs quaternions from yaw, pitch, and roll, but that's ugly and not the sort of thing you would want to do near the poles. It also requires calling a passel of transcendental functions at frame rate. JSBSim has a thing called GetTec2b which looks promising, but the other FDMs don't, not by that name anyway, which means instruments shouldn't depend upon it. Should we perhaps add this to the incipient FDM spec? c) Modeling the erratic drift by a constant rate is adequate for some purposes, but it would be more fun to make the erratic drift more, well, erratic. In Real Life it is sensitive to pitch and bank angles ... so during cruise you get complacent and start trusting the gyro, but then when you start maneuvering during the approach, it goes to pot. The magnitude of the erratic drift should be controlled by a parameter ... not by a compiled-in constant that pretends to be a constant of nature. -- This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel

The bug was introduced when the message format was changed to support optional properties. It's in the plib-based release too. This is a serious bug, definitely worth fixing. To make it more interesting, the padding inserted on x86_64 could contain garbage that makes it look like a real property. As I see it, the best plan is to add the padding to the structure and explicitly zero the padding. Then, add some defensive code to see if the padding in a received message is 0; if it is not, then verify that the property list is well-formed if we start decoding from that word. If it isn't, then assume that the message was sent by an old 64 bit client with properties starting 200 bytes after the beginning of the position message. We could bump the protocol number, but I notice that that has never been done, even when the format of the position message changed :) That would mean that people running plib FlightGear wouldn't see new clients, which is probably unacceptable.

[Flightgear-devel] flight sim protocols?
Hi, I have an overall question, which is related to FlightGear as well. I wonder what flight simulator network protocols are already in existence, and what their intended usage is. I see the VATSIM and IVAO networks - I guess they both define their respective protocols? Are these protocols to be used in an ATC-like environment, where position updates every few seconds are sufficient? Or are there protocols which would allow for, say, formation flying, where positions for planes close-by would be updated much more frequently? Are there available implementations / libraries for these protocols, maybe open source? Does FlightGear has its own implementation of these?
