[Flightgear-devel] Speech recognition and voice ATC for FlightGear
John Wojnaroski is having some trouble with SF blocking his ISP so he asked me to post this for him ...John writes:In the mean time, I posted some speech recognition stuff to the lfs website under the asr directory in the download section. it contains a perl script to run sphinx2 and sent the text to an IP, thelanguage model files, and a small c program to parse the text output created by sphinx. If you think about it the ATC language and grammar(aside from motor-mouths) is fairly concise, precise, and structured; even sparse in terms of volume -- at least on a per aircraft basis. Youcan get the binary package for Debian or start with the source from CMU. IMHO a flightgear feature that would be a barn-burner would be speech recognition coupled with festival. Throw in an AI based set ofcontrollers and you could have a VATSIM/IVAO capability 24/7 as well as the multiplayer stuffYou could use ops research concepts to route aircraft and maintain separation and control aircraft (either AI orhuman controlled) to a final approach metering fix. In fact there is ongoing research in the area of 4D trajectories. seems this would be anatural for guys like Dave and Durk. Back to Curt ...The whole idea of having a speech recognition engine understand your simple commands seems like a really interesting idea to explore. Beyond automated ATC, there is a whole host of human/machine interaction issues that could be explored. How about a voice activated flight director for real R/C pilots ... the computer could give hints to the pilot on the ground for flying a perfect approach down to landing, and the R/C pilot could give voice commands to request specific data, or switch the systems to different modes.

Personally I think it would be best implemented as a separate app that communicates with FG rather than being part of FGitself. FG has an open protocol system allowing you to easily export theCOM frequencies etc. to an external app. See http://cvs.flightgear.org/cgi-bin/viewvc/viewvc.cgi/data/Protocol/README.Protocol?revision=1.3for details. This would allow the VoIP client to be run on a separatecomputer if required. Just to jump in here with a me too ... If you could take a standard VOIP system and rig it so you could only hear people on your frequency within some range, you would pretty much have everything you need. FlightGear has all the I/O hooks you would need to query the tuned frequency. It would be very interesting if we started to see servers popping up to handle specific airports/frequencies or matching frequency within a particular region of the globe.Regards,Curt. -- Curtis Olsonhttp://baron.flightgear.org/~curtHumanFIRST Programhttp://www.humanfirst.umn.edu/FlightGear Project http://www.flightgear.orgUnique text:2f585eeea02e2c79d7b1d8c4963bae2d - Using Tomcat but need to do more?

With properties, the compiler can't spell check variable names at compile time so typos can creep in. When something doesn't behave as expected, it's worth looking in the property tree while the code is running to see if any new properties (with similar, but not quite exact spellings) have appeared. This feature is important to my ground station and it now can instruct FlightGear to use the manual flying or our autonomous navigation system to fly. Sounds like you are doing some UAV work. Do you have a web page or more info on your project? I'd be very interested to hear more details of how you are leveraging FlightGear as part of your ground station.

[Flightgear-devel] Yard Stik 3d model?
Question for all you 3d modelers out there...There is a group at my university that is using the Yard Stik as a platform to develop micro indoor UAV's. I'm trying to convince them that they should also be using FlightGear as a larger part of their simulation/visualization and development process. Would there be anyone out there interested in building a quick yard stick 3d model? We would want it to scale. It wouldn't necessarily need every tiny little detail as long as it had the basic form. I could get detailed pictures and any specific dimensions you would need. Here is some basic pictures and dimensions: http://www.electrifly.com/parkflyers/gpma1100.htmlI'm hoping that if I can get someone in the FlightGear community to pitch in the 3d model, and then get this group at my university to create a JSBSim/YAsim model, then we'd have a flyable Yard Stik in FG which would be a fun diversion for anyone interested in R/C. They are in the process of instrumenting a real yard stick, so they will be able to collect a lot of very accurate and detailed aero data. Just as an aside, I've been working with a different research group at my university to help them with their own UAV related project. We are using a Rascal 110 (which is reasonably modeled in FG already.) Last year I crashed Rascal #1 which was very depressing. During this most recent september, I took some of my spare time and rebuilt it. Yesterday I flew it for the first time after the complete rebuild/restore and it flew really great, just like it was brand new. I was very happy, especially considering how much damage was done to it a year ago. I've got pictures of the carnage and details of the restoration here: http://baron.flightgear.org/~curt/Models/Special/Rascal110_1/Rebuild/My plan in the upcoming weeks is to instrument this Rascal, carefully collect some specific flight data, and use that to refine our Rascal JSBSim model even further. I already have modeled a set of autopilot configs in FG, but once I refine the simulator model, I'm going to go back and retune the gains on the autopilot. THEN I plan to port the FG autopilot code directly to the onboard flight computer on the Rascal and theoretically, if I've done everything well enough, it ought to fly autonomously on the first try. Or else, I may be back for another month in the woodworking shop. :-) Regards,Curt.-- Curtis Olson - University of Minnesota - FlightGear Projecthttp://baron.flightgear.org/~curt/ http://www.humanfirst.umn.edu/http://www.flightgear.orgUnique text: 2f585eeea02e2c79d7b1d8c4963bae2d - Using Tomcat but need to do more?

Hi Mike, thanks for the fix, I've added this to CVS.Curt.On 10/22/06, Mike Dusseault [EMAIL PROTECTED] wrote:So I was practicing standard turns and timing myself. By the turn co-ordinator, I would complete 180 degrees too fast. The attitude indicator showed my bank angle to be more than I expected for a standard turn as well (this is in the Cessna 172P). And I realised the problem with the 50 second standard turns I've heard about and was noticing myself are because the turn co-ordinator is off. I figured out where to put the attitude indicator for a good 180 in 60 seconds standard turn and that lead me to exactly what's wrong. The little airplane image is actually slightly too high. I have a picture of one in my book, and the plane should line up with the side bars when level, not be just slightly above it.

Re: [Flightgear-devel] multiple views on separate monitors?
A couple things that could be done right now.Use something like an nvidia card with twin-view which creates a single desktop spanning 2 displays. You could create a FG window that stretches across the two displays, then cover one of those with a 2d panel. You'd have to play tricky games with the view frustum though so that the other display is centered on the center of the display, not centered between the two displays. There is an ongoing background effort to port FG to OSG. This is actually quite well advanced. There are a few remaining sections to be ported, but the bulk of the work is done.OSG will facilitate doing a lot of new and useful things, among those is drawing to multiple windows from a single app. That's still a ways out, but progressing.

What sort of maneuvers do you fly and how to get extract theFDM parameters?Jeff,Now you are asking hard questions. I'm not an aerospace engineer so I am trying to learn the process as I go. I know people do hang up a model and swing it to get the moments of inertia. What they measure and how they crunch the results to get the numbers that FlightGear wants ... that I do not know. I know you can fly specific flight tests and extract some specific parameter(s) and then twiddle your sim numbers to get that to match ... for instance, establish straight and level flight at 90 kts (+ some specific alt/press/temp), give a 10 degree aileron deflection, record the roll rate ... now go make your sim results match under those exact same conditions. Repeat for about 100-1000 other tests ... phugoid, pitch rates, flap changes, speed changes, acceleration, deceleration, trim points, control surface deflection speeds, etc. etc. I begged the gurus over at flightgear-flightmodel to help me get an initial guess at a JSBSim config for my Rascal 110. Then I took that and tweaked it in several ways until certain things felt a lot better ... roll rates, adverse yaw, pitch change with throttle change, and probably a few other things that I noticed really needed to be fixed. But this was all based on zero hard data, and only my recollection of my original perceptions ... not exactly a firm foundation. Now (well hopefully next week) I'll have an IMU/GPS unit installed in the Rascal 110 that can also record control inputs (from which I can derive things like control surface deflection angles.) So starting next week I should be able to start collecting some decent hard data ... what is the stall speed really? What is my top speed really? What control surface deflections are required to achive straight and level flight at different speeds? What is my decent rate at idle? What's my climb rates, roll rates, pitch rates, etc.? This is probably backwards from the way a smart aerospace person would approach the problem, and hopefully someday I'll learn smart ways to do these things, but for now, this is the approach I have in mind: Fly specific tests, record specific results, twiddle simulator coefficients to try to match the real results. Hopefully my embedded flight computer will someday be running nasal (no really, actually not joking here) and then I can script out specific flight tests so the computer can fly them with extreme precision, both in real life and in FlightGear and then hopefully be able to make very valid and very direct comparisons between my real flight data and my simulation results. And hopefully you noticed that much of this message is written in the future tense so bear in mind that I could just be full of a lot of hot air. I think I know what I plan to do with this, but I haven't actually done it yet, and I'm sure the real world will have something to say about my level of success, and that might (or will!) dictate at least some change in strategy along the way.

(For instance dial in some very turbulent IFR conditions at night, give them some oddball engine reading on the panel to start worrying about, now put them on an approach they aren't completely familiar with, throw in a 737 bearing down on their tail, and then fail their vacuum pump, and if they don't notice the failure, the remainder of the flight could be very short.) That's not the sort of thing you would intentionally go out and do in a real aircraft, but it is these combination of multiple factors that often lead to real problems. So you can load up a person in a sim with problems, adverse conditions, and other distractions, and really train them how to sort it all out and focus on the most important things. Also you can instantly reposition yourself at the start of an approach, so you might be able to fly/practice 10 approaches in the simulator in the same time it would take to do one complete cycle in a real aircraft. That can be a *huge* savings in your hourly operations cost, or flip it around and you can have 10x more training value for each hour of operation ... for certain tasks at least. So you certainly wouldn't buy a simulator to replace your real flying experience, but a simulator provides some extremely valuable training capabilities that could be either extremely dangerous or extremely inefficient to do in real life.

Re: [Flightgear-devel] FlightGear starting time
I think to answer quickly, the version we distribute in binary form is built with MSVC and you are building with cygwin. I think it has been reported in the past that cygwin has some serious IO efficiencies due to some sort of thread blocking. Apparently this isn't a priority for the cygwin team, or perhaps only FlightGear tickles this problem in cygwin??? Other's may be able to provide more detailed (or more of a correct) explanation.

Re: [Flightgear-devel] Confused header inclusion on IRIX with OSG present
It's been a *long* time since I've wrangled with the irix compiler, but one idea would be to remove the APIENTRY keyword from one of those lines in the header file and then see if the error for that line disappears. If it does, then you know that APIENTRY is expanding to something wrong, or something your compiler doesn't like and you can work your way backwards and see what is defining APIENTRY.Curt.

Good job Durk and Robin, thanks for the report and for all your work! I'm looking forward to the pictures! These shows are a *lot* of fun, but also a *lot* of work and can be very exhausting.Curt.

We were very pleasantly surprised by theoverall positive feedback we got on FlightGear. An event like this ispredominantly microsoft oriented. We were actually placed right across from the microsoft booth (on purpose, as we found out), and despite thefact that their presence was pretty dominant, many people were reallysurprised to find out about the alternative we were presenting.Actually, microsoft had the largest screens and made the most noise, but not everybody was impressed by them. Many people were really pleased bythe smoothness of our instruments, validity of our flight models, andthe fact the entire simulator was actually written from scratch by the community. And not mention of course that it is entirely distributed forfree (as in free beer in this case).A few people took the simulator for a ride and gave suggestions forpossible improvement:- Have a better graphical user interface inside FlightGear that includes the functionality of fgrun- There are not enough buildings in the scenery (especially in the DutchScenery that we were using)- We should get more media exposure in printed and online magazines.In addition, we have some additional ideas for improving our presentation on expositions like these:- Merchandising: Have the scenery available on DVD for sale- Have various versions of FlightGear (source, binaries, scenery, basepackage) for sale as well- Have (a) beamer(s), so our graphics look a bit more impressive than on a 17 TFT screen- Bring adaptors to connect real aviation headsets to our equipment.Okay, that's it for now. Tomorrow's going to be pretty busy again, andhopefully we can present some more news.

Re: [Flightgear-devel] Again: VATSIM and FlightGear?
Hi Holger,Yes, I think a separate black box gateway application to vatsim would be a very plausible way to move forward. You could keep all the NDA/Proprietary stuff in it's own sandbox and separate from FlightGear. That way you don't have to worry about incompatible license issues. Your black box knows how to speak vatsim and flightgear, and flightgear doesn't need to learn how to speak vatsim, which is probably not possible anyway given their licensing restrictions.

On 11/7/06, leee [EMAIL PROTECTED] wrote: I suspect that the graphics will prove to be the trickiest problem - it's byfar the greatest resource user - Right, in all this we need to remember that in all our past benchmarking, the graphics themselves account for 90-95% of the workload. OSG provides some opportunities to thread the graphics rendering itself, but beyond that, the remaining 5-10% of computational effort is pretty small in comparison. Further dividing that up into additional threads may not be such a huge win, unless as Durk says there are tasks that are bursty like metar fetching which has to block on network IO ... that makes a lot of sense to put into a separate thread, but does anyone realize the pain we wen through to debug that simple task? And then does anyone recall that a subsequent patch broke it all again and we had to wind all the way through the process and figure it all out again. Lot's of pain was endured by at least a couple developers to make that work. So yes, threading does indeed make sense in certain specific contexts, but we need to be really careful about what we do, exactly why we do, and what specific peformance benefits we *know* we will get by threading some new task.

And the biggest complaint:+ No released version of OSG works with FlightGear, nor does their CVS head. Hi Andy, all extremetly valid points that cannot be contested. A couple points though in return.First, the scene graph landscape has always been less than ideal. I remember going though the thought process the first time around of which scene graph library we would pick and at the time, plib had lots of limitations and was very new, but seemed like the least evil of the available options. We can put forth some pretty strong complaints about OSG, but we can also do the same with Plib/ssg.Plib/ssg has never even had multi-texturing support. Our attempts to submit patches to do that were rejected. Has plib/ssg seen any real development or advancement in the last 5 years? No shader support, no threading support, etc. Do any other major well known projects use plib/ssg besides FlightGear? Maybe a handful of smaller apps and home brew games? Your last point that we require a branch of the OSG tree is probably the most problematic. However, getting the required changes and patches and fixes into the next OSG release is the top item on Mathias's todo list. I am led to believe that this is only a very short term problem for us. We do have some friends highly placed in the OSG world, so I am confident that we will get our changes into the main OSG branch in due time.Curt.-- Curtis Olson - University of Minnesota - FlightGear Project http://baron.flightgear.org/~curt/http://www.humanfirst.umn.edu/http://www.flightgear.org Unique text: 2f585eeea02e2c79d7b1d8c4963bae2d - Using Tomcat but need to do more?

On 11/7/06, Ampere K. Hardraade [EMAIL PROTECTED] wrote: Shouldn't there be three?Or is FlightGear not getting inputs from the userwhen it hangs?Well by my count: 1. main thread, 2. scenery paging thread, 3. weather fetching thread. My opinions on:Subtle bugs -- these get hidden anyway without the help of multiple threads.Seriously, and believe me when I say this. Threads open the door to a whole new level of even more subtle, difficult, and hard to trace bugs than you would have otherwise. I suspect you won't buy that, but it's true. Threading bugs are nasty because subtle timing issues can produce code that works fine for hours or perhaps only bomb once every couple days. This can be incredibly difficult to debug because it is nearly impossible to reproduce and the debug/edit/compile/run cycle can be hours or days for one iteration. The tendency is often that if it works most of the time, and it's hard to find the problem, let's not worry about it and move on. Pretty soon you have an application that has trouble running more than an hour or two without crashing due to a number of different bugs that have crept in. And if you get to that point, you need the resources of, oh, let's say microsoft, to dig yourself out of that hole. Not that I would pick on microsoft in this context for any particular reason. Seriously, threads are really cool in a simple text book example, but in a complex real world application, danger, danger, danger! Consider one end, you have a code that takes up 0.5% of the processor timeupdating the property tree, and on the other hand, you have an externalapplication that is feeding off these properties to drive a hydraulic motion platform. [snip]#1 is completely out of the question, as someone could be killed.So, #2 isthe only viable option.Unfortunately, single thread and #2 don't mix,because alarms would be going up all the time. Clearly there are cases where you can't proceed with out threads. Threaded scenery paging is one, threaded metar fetching is another. Neither consume a huge amount of CPU time over the course of the application, but each has specific reasons why it makes sense to put those in a thread. But threading even these simple things has been extremely painful. I've been intimately involved in that pain several times for each of these threads.Really! We should go out of our way to find a workable non-threaded solution before we add new threads to the code. If there is an abolute requirement from an architecture standpoint, then ok, let's talk about it.But if we just want to make use of our fancy multi-core CPU's, well then, hold on a second, what chunk of cpu intensive stuff are we planning to move over and run on another thread on another core? My whole point is not that we should never do threads because we already do in a couple special cases. But we just need to be really smart, really thoughtful, and really actually require a thread before we put ourself through the pain and a new order of magnitude of subtle bugs again.

Re: [Flightgear-devel] FlightGear OSG build problem
I should double check, but I believe I'm running glut-3.7 on my home machine and didnt' have any build problems (Fedora Core 6.)For what it's worth. The full screen (game) mode of freeglut (any version) is horribly broken under unix. SDL full screen works fine, but locks out all other heads on a multiheaded system. Old, original glut (well 3.7 anyway) is the only version I've found that can successful go full screen with FlightGear on one display of a multiheaded system while leaving the other head(s) usable for other things (like an operator console for instance.)

Re: [Flightgear-devel] Next release. Any timetable?
On 11/9/06, Steve Hosgood [EMAIL PROTECTED] wrote: I don't know what Curt uses as a metric for deciding if a new releaseshould happen, but the time delay between the current 'stable' and theprevious one was about two years - too long I'm sure. v0.9.10 was released in April. We have long since abandoned the even/stable odd/devel release approach. 0.8.x is long forgotten and really was never supported beyond a couple fixes people back patched into it early in it's existence. Just to make it clear to everyone. Right now I am struggling with a couple critical dead lines at work. The pressure is on me for my day job, and I'm screwing my schedule and deadlines right now by just taking the time to reply to this message. But, it's seems like for pretty much this entire year, the pressure at my day job never lets off, so I have to take a breather once in a while even if it provokes my bosses to scream at me even louder. So combine that with a wife, 2 kids, and needing to spend some time with them so they don't forget what I look like, and it becomes a real struggle to stay on top of life. Sometimes I feel a bit like this poor guy: http://www.mypartypost.com/watchvideo/907/Commercial-Budweiser_(Referee)So please, if people want to panic because we haven't had a recent release, I'm sorry. If people want to panic because OSG has broken a few things temporarily, I'm sorry. If I'm behind on my email, I'm sorry! FlightGear is in large part an engineering simulator and needs to track the best technology of today to stay current and stay useful. But there are a lot of competing needs and goals within this project. There will always be competing ideas and needs, there will always be tension and debate and friction. But that is good, that is how we get stronger and better. If there was zero friction, zero competing ideas, zero debate about anything, we'd probably be going no where useful. It's just important to remember to be patient and civil and recognize that a healthy debate is a good thing. Different ideas and different goals and different directions are a good thing. It's not always comfortable, but it's a critical element to our successful development.

Re: [Flightgear-devel] GPL Violation?
Ok, I hope that everyone will stay calm and not take the law into their own hands so to speak. I have contacted the FSF to get their opinion as to whether or not there is even a violoation here. If there is a violation, I would hope to have an opportunity to contact this ebay vendor and explain the details of the violation and offer him/her an opportunity to restructure their ebay ad in a way that fully satisfies the terms of the gpl. They may be a FlightGear friendly person, they maybe a younger person, who knows. It's not fair to bring down the full force of our wrath first without giving them an opportunity to fix the problem. If I do not make headway with that effort, then the next step is to contact ebay. If we still have no satisfactory resolution at that point, then we'll need to decide then how to proceed. As John pointed out, he's only sold two of these. I'll probably vote for putting him in a cage for 10 minutes with Arnt. Regards, Curt.

Re: [Flightgear-devel] GPL Violation?
That's all well and good, except I think we want our screenshots to be redistributable and used and shared as much as possible. This is an open and free project. I really want to avoid going down the path of having to decide who can and can't use our screenshots and then trying to gin up appropriate justification for whatever arbitrary choice we make in any particular situation. This might be one of those cases where it's better to just allow something that we may not be 100% happy with in order to fully protect every one's freedom. Not that I would support or defend his actions, but perhaps I would allow it so that everyone else can have the same freedoms to hopefully do positive things. Curt.

Now that I am hosting the FlightGear web site with a commercial hosting service, it becomes quite easy to setup online forums using phpBB2. I know our development culture is built around mailing lists. I'm sure the FlightGear community will be decisively split between forums versus mailing lists if I ask people's preferences ... so I'm not expecting a consensus here. Is this anything that is worth exploring? Is it worth having both options available? Would end user support benefit from forums? Would forums be useful for those that have trouble with sourceforge's spam blockers? A backup communication mechanism for when the sourceforge email lists experience their inevitable down time?

It would be nice to get this all sorted out and make it clear what the different options do or don't do and how they play together.

Re: [Flightgear-devel] Airfoil bending and geometry animation
For wing bending the Ornithopter used an interesting approach to model the flapping wing animation.

I have done some work capturing IMU/GPS data from a live UAV and playing it live (or replaying it later) in FlightGear ... optionally with the multiplayer features turned on so we can track the uav in google maps/earth. There are a variety of ways you could pull this off, but here is one suggestion. I have written/adapted a couple utilities that can load a saved data file or read the data in live from a serial port and then pass it along to FlightGear. This code lives in the FlightGear CVS repository under .../source/utils/GPSsmooth/ (the naming of this directory doesn't exhibit a lot of forethought, but that's what it is right now.) If you wanted to use this option, you would mostly likely have to adapt the MIDGsmooth or UGsmooth application to parse your own data format, but everything else should pretty much be the same. If nothing else you can explore this directory to get a few ideas. You could probably reformat the data so it could be loaded and replayed by flightgear directly, but I haven't fiddled with that end of flightgear in a *long* time so someone else might be able to offer more current advice for doing that.

Re: [Flightgear-devel] Addressing the discontinuity that occurs when using discrete terrain altitude data during landing...
On 12/7/06, Antonio Almeida wrote: I've been working on a prototype flight simulator and I'm running into an issue I have no idea how to solve, so I decided to ask here since this very same problem might have been addressed in FlightGear. I want to model the landing of my aircraft. My problem lies in the altitude data. The data I have to use is a pixel map, which means that one square (which has around 100 meters side) has a certain value of altitude and the adjacent square has a completely different value... This means that if I try to land the aircraft in the border between two squares... it will either fall down or crash against this virtual discontinuity! I'm betting there's an obvious solution to this, but I'm out of ideas!... Any suggestions? In FlightGear, our terrain is modeled as an irregular mesh of triangles. We can lookup the terrain elevation at any point. As you move the terrain elevation value will change smoothly. It's not smooth in the sense of the first or second derivative, but that doesn't cause us a problem, especially on airport surfaces because we go to extra precautions to make sure all the elevation points are fitted to a smoothed surface (that approximates the original terrain data.) You might want to consider turning your grid of elevation heights into a triangle mesh (which you must have to do in order to render the data) and then sample your elevations off the mesh rather than the original data. Or maybe you could just interpolate between mesh points ... that might be even simpler.

On 12/12/06, Martin Spott [EMAIL PROTECTED] wrote: errrm, and, at least some of them don't even dare to think of using current versions of FlightGear. I was told they're afraid of running into the hassle of reworking half of their interface with every new version of FlightGear, because the interface actually is not what people would call a stable protocol. The biggest issue is that people with proprietary software on one end get locked into a specific version of FlightGear because as FlightGear evolves, their proprietary tools can't or don't follow very quickly. That said, the most recent version of the aerospace blockset for simulink supports multiple versions of FlightGear including v0.9.10. However, some people don't or can't upgrade because of the software costs. Actually this matches with the result of an experiement that I did earlier. I picked a few network packets with the network analyzer and fed some of them into a running FlightGear instance on the same platform as the packets were generated (FreeBSD/i386). I managed to 'move' the aircraft by manually tweaking some bytes with the hex editor and returning the captured packets to FlightGear on the same platform, but it didn't work by feeding the same, hand-selected stream to FlightGear neither on Linux/AMD64 nor on IRIX/N32. Work was done to improve the NetFDM structure prior to v0.9.10 so if you did your experiements earlier than that, the picture has most likely changed. Mathworks actually tested their tool on quite a few different platforms (including Mac OSX) and made a few recommendations to improve the situation which we followed up on. Don't get me wrong: I don't intend to shoot you about inabilities of this network protocol - well, I once was attepted to do so several years earlier, but this is another story ;-) - but we might save people valuable time if we make sure they don't get mislead. No, say whatever you like, joking or not, and I'm not offended. There isn't a single one-size-fits-all communcation protocol. That's why we have several mechanisms available in FlightGear. The NetFDM is perfect for certain situations and applications, and completely the wrong approach for other situations. There is some work (moving very slowly because involved) to create an xml specification for a binary protocol so an external application can feed flightgear an xml file to produce binary output matching exactly what that external app wants and expects. Kind of like the generic protocol only the underlying data is transmitted in binary form.

And even for 32 vs. 64 bit systems, they all still use a similar convention where integers and floats are 4 bytes and doubles are 8 bytes. As long as we confine ourselves to ints, floats, and doubles (and use an int for boolean values, etc.) then we should have an extremely high probability of getting any two machines to talk to each other successfully. I do know of one exception ... the X-Scale architecture seems to swap the first 4 and last 4 bytes of doubles, so they aren't using a standard big or little endian representation for double floating point numbers.

I think there is some hen-and-egg problem hiding here: The software-toolchain that is called TerraGear features a significant complexity and therefore Curt dislikes the idea of having everyone modifying the source of it. So he's the only one who has the ability to change things. I do understand Curt's attitude here. Nobody wants to take responsibility for such a complex beast when you're at risk of pouring numerous hours in bug fixing, just because some person wasn't aware of the scope of his fix he added to the source base. Everyone knows that Curt is a very busy man. Actually it takes you several months and multiple reminders to convince him to apply even a simple patch. As a result of this, those few people who _do_ have the knowledge of how TerraGear-tools work (I'm not talking of myself here), don't feel significantly motivated to improve the current state Finally TerraGear mostly remains as it is. To quote another recent poster ... ... the above statement above is not completely accurate, and not accurately complete. You do have some great sounding talking points though. Many people have contributed to terragear over the years. You are right that it is very complicated code and people in the past have proposed patches without sufficient understanding of what they were changing. There are exisiting bugs in the code that have come from well intentioned patches that did make it into the code base ... things we are still trying to deal with and resolve. So I do try to be very careful about changes. But many people have indeed contributed patches or entirely new tools to the tool chain. Where do you think the vmap support came from? How about the code to do an efficient TIN fit/simplification of the original gridded terrain data? I suspect there may be a few specific developers that might not appreciate how you trivially minimize their very important contributions to the core terragear code base. There have been some egregious cases of neglect -- especially this past year -- where I have really dropped the ball on applying patches. I do have a couple things in my inbox at the moment, but I'm going to need to take a couple days off for the holidays here. But most of the time I'm able to come up with reasonable turn around times for patch submissions. I will reiterate that 2006 has been the worst year of my life in terms of work stress and just being completely overwhelmed with everything on my plate ... so your statements aren't completely without basis and you are building on top of nuggets of truth, but I don't think they are a fair charactarization of the overall situation either. I'd propose to Curt to let at least few others work on TerraGear as well without being required to ask for his blessing of every single patch. I assume that such a move is suitable to motivate people at least to put a little bit of effort in cleaning up the TerraGear source - which might serve as a good start for further improvement. I'm open to discussion here ... and I do believe that I'm not the only developer that has write access to the TerraGear cvs repository.

On 12/29/06, Roberto Inzerillo wrote: That's the point Curt. I don't care about that now. That's not my aim in any way. Your algorithmic approach suits well when thinking globally, and you have to, because you provide a base to a global scenery generation process; that has to follow strict, standardized rules. All that is good but this thread is not about a new way to get the global scenery regenerated with more details, it's about customizing (with high level of freedom) just a few airports, juts the ones a few people are especially interested into. Right, we are talking about the same thing here. I see space for doing that, it's just about modelling geometry of restricted world areas and integrating it with the already existing terrain mesh; but tools around do not provide a way to develop it (I mean taxidraw/fgsd, maybe even Terragear tools). I don't know if I was successful, but when discussing the upcoming apt.datformat to include a much more flexible taxiway spec, I also lobbied to have an airport boundary also included. If this boundary was fixed and never changed, then a user could change anything inside that boundary (leaving the actual boundary points intact) and their airport would always mesh in perfectly with the surrounding terrain, even if we autogenerated the world again. Right now the airport boundaries are derived from the runway/taxiway data so if those change in the slightest bit, the terrain cutout for the airport also needs to change ... that's a hard problem to deal with. So back to your point, there's no reason you couldn't convert an airport model to a more convenient 3d model format and then edit it in what ever tool you want ... ac3d, multigen creator, blender, etc. Regards, Curt. -- Curtis Olson - University of Minnesota - FlightGear Project http://baron.flightgear.org/~curt/ http://www.humanfirst.umn.edu/ http://www.flightgear.org Unique text: 2f585eeea02e2c79d7b1d8c4963bae2d - Take Surveys.

Re: [Flightgear-devel] location-in-air ... magnetic bearings from the reference
On 1/3/07, John Denker [EMAIL PROTECTED] wrote: First, some background information. Suppose we are up in the air, 10 nm west of KXYZ airfield (which is colocated with the XYZ vortac). [snip] To summarize: With rare exceptions, locations are specified using the bearing /from/ the reference. Also note that in all cases these are /magnetic/ bearings. So ... I recently used the location-in-air popup menu for the first time. I selected a distance of 25 nm and an azimuth of 270. I had no doubt that this would put me 25 miles west of the station. Imagine my astonishment when it put me 25 miles east of the station! Yes, that does sound confusing ... An additional nuisance was that this location was /true/ east not magnetic east. Just to add to the excitement, this put me below ground level, in the mountains east of the station. But that is only tangential to the present discussion. Computers just do what you tell them to do. :-) One final remark: Pilots talk about radials, courses, and bearings. The word azimuth is not used much. It's a perfectly fine word, and certainly has its place in the /internals/ of a flight simulator. OTOH there are lots of users (including me) who want the user interface (i.e. pilot interface) to be as realistic as possible. The existing location-in-air popup is shockingly unrealistic from a pilot's point of view. This needs fixing. The tricky part is fixing it in a way that doesn't break legacy usages. I suggest we start by making the following distinctions explicit: --true-bearing-to --true-bearing-from --mag-bearing-to --mag-bearing-from Currently, the command-line interface implements --azimuth, which is documented to be to the reference, and is apparently equivalent to --true-bearing-to. That's OK with me as far as it goes. 1) I suggest that the command-line interface be extended to support the four explicit bearings itemized above. We can continue to support --azimuth as a fifth option, synonymous with --true-bearing-to, but it should be mildly deprecated on the grounds of ambiguity. I think that --azimuth itself is a rarely used option so I would be a little hesitant to split that into 5 options, none of which will probably be used by more than one or two people. I think it makes a lot more sense to focus on the gui dialog box. 2) I suggest that the location-in-air popup be revised so that it uses the equivalent of --mag-bearing-from, not --azimuth. As part of this, I suggest changing the wording on the popup from: Azimuth (deg): ___ to Bearing: ___° mag from I don't think this will break any of the documentation, because AFAICT the location-in-air popup isn't documented in any detail anywhere. I'd be happy to try implementing this myself, but I would appreciate some help or at least hints. *) I've already changed the appearance of the popup. Easy. *) I spelled out deg. I tried putting the ° symbol in the xml file, but it complained of a parse error. Using deg; didn't work, either. Any suggestions on how to encode symbols? Our font has a very limited number of characters available so I don't think this symbol is available. *) I tried putting offset180/offset and offset/environment/magnetic-variation-deg/offset commands in the location-in-air.xml file, but the system appeared to just shrug them off. No effect. What's the trick? I think there will need to be some support in the code for this. It's easy to compute the local magnetic variation for some lon/lat, but the dialog boxes just set property values and trigger internal function calls (and maybe a bit of nasal here or there.) The reposition dialog box doesn't do any nasal, it just sets a bunch of property values and calls the reset function. So in this case I think what needs to be done is to modify the reset function (in a backwards compatible way) to understand the property values that are set from the dialog box and do the right thing with them. Has this issue come up before? I didn't see any sign of it. I'm not aware of this issue being brought to light in the past. I suspect that most people don't do a lot of complicated initial positions, but we do want this to work intuitively so I would welcome any changes to improve the in-air reposition dialog box.
