Re: [Flightgear-devel] Multitexture support (was: RE: [Flightgear-devel] Roadmap/brain dump)
Guys! We can't achive MSFS2002 quality without multitexture support so First task we have to work on is multitexture support Steve Baker said that he wait until shader languages become popular and OpenGL2.0 come out so or we wait OpenGL2.0 or implement multitexure I start work on it my primary task is implementing light lobes of aircraft and this can't done without multitexture Marten Stronberg gave me some sources that he works on If someone intrested in I can give sources If we will do this FGFS become the coolest sim in the world!!!

The FS2002 crowd have a freeware utility called AFCAD that performs a similar task. It produces a structured text output file.

I can heartily reccomend two OpenSource packages for doing this OpenEV http://openev.sf.net OSSIM http://www.ossim.org For those into scriptable interfaces OpenEV should a treat. OSSIM is a bit more of a bear to get your head around but worth it if you want to mossaic Imagery from different sources They both have excellent shapefile support and support most of the standard raster based formats. For those on Win32 the VTerrain package has a program that can assist in automatically extracting buildings from DRGs http://www.vterrain.org/Implementation/Apps/BExtractor/index.html and another to assist in laying out the final model, roads buildings airports ect, http://www.vterrain.org/Implementation/Apps/VTBuilder/index.html Both of these programs store their results in XML files built using SimGear's EasyXML package so we should have no problem translating them Cheers Norman ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

However, the amount of work that has gone into specifying the taxiways and aprons at major airports must be *huge* - it would take a long time to replicate it with a better system. FWIW I'm currently writing a program to allow the laying out of a logical taxiway and parking place network for AI planes to follow over an image of Flightgear's rendered taxi and runways by clicking on it where intersections etc are wanted. I'm sure this could eventually be extended to allow the layout of taxiway and apron polygons which could then be fed into Terragear as area polygons. Alternatively Frederic's fgsd might be another possible tool for the job - although I haven't got it running yet I believe his intention/achievement is to allow the editing of scenery superimposed over calibrated maps or ariel photos, which would ease the task of getting the aprons/taxiways etc in the right place.

Even if we can't get actual developers of (PD) add-on Scenery on board for FlightGear, we might profit from their knowledge. I am pretty sure, there are several developers of (free) add-ons with terminal maps and, maybe, even bitmaps ready to use, which they *perhaps* might share with us. For instance, there are quite detailed airports maps of gates available for a tool called AFCAD (adding gates for AI planes - personally I never used it myself, though). Not sure if this approach will work, but might be worth a try. If you think it's reasonable, I might check what's available for FS2002 from a few sites I know and give you a digest.

There's no single common identifier for a field Welcome to the joys of data management. I recommend putting all of the DAFIF airports in separately for now, with a different "source" field: source = xplane source = dafif Then, late, you can specify rules for which ones get included or excluded in a build (i.e. the DAFIF KSFO and the X-Plane KSFO are treated as different, mutually-exclusive airports). > Also, how do we want to handle updates - I can track how everything > was last updated now, so from an initial import of the xplane > database I can update it with DAFIF, *but* since the DAFIF info has > no taxiway data, if the runway positions get changed slightly the > taxiways won't line up.

During development cycles I'm usually not able to follow the changes as fast as they happen to occur. This means that updating the manual is pretty useless, because a feature often already has changed before anyone had the chance to write a single line for the manual. So in purpose to get the manual up to date with the software I need way more that a whole weekend's time to do testing of different features on at least two different platforms and for 'tuning' the manual (I think Michael needs about the same amount of time). Sometimes there are questions left that would be nice if they were answered before the release This way I have to find a whole weekend that I am able to keep clear from any other stuff - this is not always the nearest weekend If there was a longer period _without_ any feature changes but only bugfixes before a release (maybe three or four pre releases) this _might_ prove to be useful not only for the maintainers of the manual but maybe also for the 'staff' doing the real work on the software, Martin. -- Unix _IS_ user friendly - it's just selective about who its friends are ! -- ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

On the subject of runways - I've been working on the database today. I can import and export the xplane database, and have some code which parses the DAFIFT data, and compares it with the existing database, however: 1. Not all airfields in the xplane database are in DAFIF 2. Not all DAFIF airfields are in xplane therefore 3. There's no single common identifier for a field Also, how do we want to handle updates - I can track how everything was last updated now, so from an initial import of the xplane database I can update it with DAFIF, *but* since the DAFIF info has no taxiway data, if the runway positions get changed slightly the taxiways won't line up. Updating *only* fields with no taxiway info, or which were last updated/created by DAFIF data is possible. Manual updates are another problem - if someone goes to the effort of correcting data then we don't want to overwrite it with potentially less accurate info from one of the databases.

The Dafif has separate landing and takeoff distances for each direction of each runway, and on the airports/runways I've looked at (in the UK) these seem to correspond to the displaced thresholds. To be quite honest I never realised one could use the bit with the arrows for takeoff, although thinking about it it wouldn't make sense not to. Anyway, if you let me know what format the data would be most useful in, then I'll write a program to extract it from the Dafif and convert it to your preferred format.

The policy is that we say nice things about sourceforge and we appreciate the service they provide to the open-source community. But they really pissed me off one day with some of their policies, so we vacated and moved all our services to two machines I admin locally here at my university. Subsequently, sourceforge relaxed some of their objectionable policies, but I'm happy taking care of the servers myself. Unfortunately, SF doesn't seem to have any mechanism for removing mailing lists, or projects from their system. So, you will find flightgear stuff at SF, but it is completely abandoned, at least as far as I'm concerned. I'd be happy to give someone admin rights if they want to go twiddle over there and be responsible for receiving all the spam we still get to the abandoned mailing lists. Really, SF is great, but I'm happier on machines I admin myself.

David Luff writes: > As for 1.0, although its just a number, I personally think its a > pretty significant number, and probably worth a bit of work > polishing bugs , user interface, and installation problems out as > much as possible before release. David, Definitely we want to get out releases that have no major bugs and have all installataion issues resolved. However, there are a couple things that work against us. 1) Time. Putting out a good release takes an immense amount of time. I figured that I had at least 40 hours of real time into the 0.8.0/0.9.0 release. That's over and above my real job, my family, etc. etc. People need to realize how much time, and how much effort putting out a good quality release actually is. People might argue that there were still a lot of problems with the 0.8.0/0.9.0 release which goes to my point exactly. I really needed to find 80 or 120 hours or more to do things right. 2) There seems to be a principle at work that very few people download and test development and pre-releases. Mostly it's a few developers who already know all the tricks, already have all the prerequisites on their systems, etc. This means that the big flood will come after 1.0 is officially released. That will be when all the bugs and installation issues and other problems are reported, and unfortunately not before. I'm open to suggestions, but I've tried a lot of things already, and what ever I do has to be able to fit into my reasonable time limitations. Finding bugs after a release isn't necessarily bad in the grand scheme of long term flightgear development, but it can make it look like we do a careless job, or ignore certain platforms or compilers. I can vouch for Debian Linux since that's what I run personally, but I don't have time or resources to build and test on other platforms myself. This probably goes to David's point that CVS is actually the most stable, becuase it's not until after we do a major release that the bulk of the real bug reports and usability issues start pouring in. However, I'm usually not keen on another 40-80 hour go around right after finishing the last release. 3) Expectations are somewhat different for us than many other open-source applications like "autoconf/automake". Those guys just wrap up a tarball and release it and are done. We have to coordinate with the base package release, people expect prebuilt binaries, cd-rom images, etc. I'd love to just do a source code release, it would make my life simpler. Maybe I should consider it seriously. But then inevitably, I personally (since I'm the primary flightgear contact) get flooded with questions, complaints, people howling that they shouldn't be expected to compile an application from scratch, or have to learn unix, or have to read instructions, or type from a command line, etc. etc. People want a Windows/Mac/Linux installer. Download one big file, double click on the icon and it's installed and all perfectly native to whichever platform they are on. I haven't the time to do this myself, and apparently (since we don't have these sorts of things) no one else does either. But there seems to be an underlying expectation that someone should be doing this stuff. I'm not sure who that would be though. 4) There is too much of an attitude or expectation overall that some magical core of developer(s) (i.e. someone else) will do everything, and make everything work, so that any end user can then point and click and everything works perfectly the first time. But, none, or very few end users are willing to try the development and prereleases and report bugs in advance. A few "other people" are expected to keep all the documenation perfectly in sync with development. "Others" are supposed to make sure everything works perfectly with your platform, etc. etc. I think our limited attempts to do this draw people into thinking that "others" have infinite time and should just make it all work magically. But this is open source, we are the "other" people that need to make sure this happens. I can do a bit of it, David can do a bit, Norman, Erik, Christian, Andy, etc. etc. (not to single out specific people). But when FlightGear-1.0 doesn't build cleanly on (for instance) Mandrake version X.Y.Z using gcc-x.y.z who's to blame? The person encountering the problem needs to recognize that the developers have done their best and already put in way more time than they should have. We need a lot more help in these sorts of areas than we are getting. I'm not really ranting against end users here. I understand that a lot of them really don't have the tools or experience or resources to make useful bug reports or participate in fixing problems themselves. But when they do run into problems, they need to h

[Flightgear-devel] status of open bugs at sourceforge.net/projects/flightgear ?
In 2001 David Megginson had submitted bug no 433286 "Sun lights plane at night". to http://sourceforge.net/projects/flightgear/. His summary was: Sun lights plane at night. After the sun disappears below the line of sight, it continues to light the plane throughout the night; the part of the plane facing the sun (below the ground) always glows. The fix is to create non-directional ambient light at night, possibly together with a weak light source for the moon. Recently I found similar conditions, when the sun is very low at the horizon. Then a rotating aircraft reflects too much light onto the sky and makes its color changing with each rotation. So it seems the sourceforge bug is still present and the bug tracking system appears unmaintained. What is the current policy regarding http://sourceforge.net/projects/flightgear ?

I think that what it boils down to is that Flightgear is an primarily an end-user application where feature set is more important than stability to most users, unlike something like the autotools say, which are basically a building block to other applications, and where stability and 'just working' are likely to be more important than new features to most users. As for 1.0, although its just a number, I personally think its a pretty significant number, and probably worth a bit of work polishing bugs , user interface, and installation problems out as much as possible before release. It might also make a good opportunity to test Curt's contention that the front page of Slashdot wouldn't break his servers :-) There seem to be some problems with the JSBSim gear model which I'd have down as a show-stopper for 1.0, and I'd have thought that displaced thesholds and the arrows pointing to them would have to be pretty high on the list of features that would be expected to make it in. My personal hope as a non-US citizen is that world-wide DEM-3 data from STRM becomes available prior to 1.0, but I'm not holding my breath on that one any more.

That may be true. Personally I keep my focus on the development branch, and no one that I can recall has submitted a patch to the stable version so it is still sitting at 0.8.0. If there are problems with this branch and people want to use it and make it even more stable, then by all means, please submit patches.

There is OpenGC, but that isn't designed to just drop into flightgear. It's more useful if you are building a cockpit with multiple pc's and multiple displays. This is an area will have to explore and put some more thought into. It may work best if we actually code up these sorts of displays rather than trying to abstract them out too much and creat a generic glass cockpit display tool box that is ascii file configurable.

I guess we can play into that a little bit since so many people expect it done this way. I think the biggest thing we need at this point is a full fledged gui that allows us to change all the important things on the fly without having to exit and restart with different command line options. It would also be nice to have a couple more aircraft that are finished from top to bottom including good flight model, good external animated 3d model, good internal 3d cockpit, decent sounds, etc. I'd like to see something like a 737, some sort of smaller commuter jet, some sort of regional turbo prop, and maybe a few more small general aviation aircraft. It would also be nice to have the default startup aircraft be a C172 with a 3d cockpit, but the c172p-3d and c172r-3d need a few remaining tweaks before they can be made into the default. I think most of the software/programming pieces are in place, we just need to crank up the aircraft assembly line and start kicking out some nice stuff. ATC Flight Sims is sponsering Martin Dressler to build a really high fidelity full screen C172-S panel. This is initially 2d, but my understanding is that these are easy to paste onto a 3d panel, right? There are a lot of hooks in place now for doing a much better gui. It would be great if someone would be willing to take on this challenge. I'm not sure PUI is the greatest tool for making a full fledged GUI, however, it comes for free as part of plib, and itegrates directly with FlightGear, and we already have several examples of menus, and dialog boxes, so there is a good starting point for someone if they want to work on this. FWIW, I'm working on an external GUI written in perl-tk as part of a side project I'm involved with. I've been asked to hold off releasing the results to GPL, but the plan is to eventually make it GPL'd once it is finished. I'm not sure this will be generally usable though for a couple reasons. 1) It's written assuming a specific _single_ engine aircraft with specific systems. 2) It's written in perl-tk with a couple other perl network dependencies. This is a snap to get running on Debian with apt-get, but other users/platforms could find it challenging to get all the prequisite pieces in place to run a perl-tk script. 3) It runs as a separate program which means you have to configure some networking options in FlightGear and do additional setup stuff up front before it will work. This will be confusing to 'average' users if something like this is going to be the default gui. Also, because it runs as a separate application/window it's going to have window overlap/screen space issues with FlightGear. It's pretty trivial to handle this if you have virtual desktops and expect things to work this way, but if you come from the world of giant monolithic do everything all in one applications, it might not go over very well. It's designed to run as a separate instructor console so this seperateness is an intentional feature. When done, it should have some nice features. It will allow you to preset your position on the ground or in the air, relative to an airport/runway, a VOR, an NDB, or a Fix. It allows you to edit winds, cloud layers, temp, pressure, etc. It allows you to specify faults or groups of faults. On start, it syncs with the internal state of the current running flightgear; so if you startup the gui after flightgear and the vacuum system is already failed, the gui reads this and keeps in sync. Right now I'm working on tracking the flight and plotting your approach. Because it's perl-tk, I will be able to dump the plots to postscript with a single function call ... My hands are currently tied with respect to making this available under the GPL in the near term, but I would be thrilled to help nudge/push/shove/bulldoze someone else in the right direction if they wanted to work on something similar that was better generalized for the needs of the flightgear project (i.e. something that would handle aircraft selection, faults for multiple engines and different engine types, and maybe a few other options that a general purpose flight sim would want.) All the hooks are there in FlightGear to do these sorts of things as an external script/program (or internally as with PUI.) Anyway, sorry for meandering from topic to topic ... :-)

What is the script manager? David comitted a new FlightGear/src/Scripting directory containing early scripting code. At this time it's a matter of registering and running a script in one go. I've made a script manager where you could register a large number of scripts (for example at startup), which will run at a predefined priority over multiple frames. The scripts can also be stopped and started again individually. This means it would be possible to run certain scripts for the lifetime of FlightGear without a big performance hit, and with the abillity to manipulate FlightGears internals.

Who's working on the FlightGear network code? Can anyone provide background on what work has been done, and what the stated direction is? Mike - I'm working on a network module. It uses UDP packets for communication and a client-server type model. The system is in early stages of building, the data-protocols themselves are 'finished' and working, I'm currently trying to make it work in FG. The current 'bug' is that new FGModelPlacements don't get updated when I want them to but I'm sure it will get fixed soon when my new graphics card arives end of the week (my old card was kind of slow (matrox G450 DH)) If anyone wants to help, I'm searching for good prediction algoritmes to extrapolate the position of the plane for a max 1 sec interval.
