[Flightgear-devel] Trains?
A professor at the University of Minnesota is looking at doing a project to evaluate several different combinations of train crossing signs. This will be a psychology style experiment where you set up maybe a dozen different scenarios, run boat loads of people through, and then take statistics on what combination of signage works the best and what people like the best ... something like that ... I don't attempt to understand the world of psychology ... :-) They want a system that is mostly non-interactive (so that they can have a room full of people watch the scenario at the same time.) Essentially you are driving in a car (which you don't see), you come up to a train crossing, there is a train actually crossing in front of you, and the signage does the appropriate thing ... in this case it's either a static sign, or a sign with different combinations of blinking lights. FlightGear seems like a perfect platform to rig up their experiment. It's free, it can run on just about any OS, it only requires a single computer, we can script the view point motion, we can script and animate the signs (this is daytime only), we can script and animate the train, it should be all doable with some 3d models and a few nasal scripts. There's a guy here who can do the environment model and the signage. I'm planning to set up the xml animation files and do the nasal scripting. So my question is this ... to save us some time, does anyone out there have a 3d train model in their back pocket they would be willing to contribute to FlightGear? I'm thinking diesel locomotive, some sort of box/cargo cars, something in plausibly north american markings. The train will be travelling in a perfectly straight line across perfectly level tracks so we don't have to worry about the complex linkages between the cars ... the whole train can be animated as a single model, but it would be nice if the wheels spun relative to the train speed.

Re: [Flightgear-devel] Integrating real-time vide and images into FlightGear
Karen, There were some papers at the AIAA InfoTech conference that mentioned using FlightGear. (There were a number of papers on real-time video as well.) Here are a few of the papers I found with a quick search on the AIAA website: 1. 93% Fusion of Optimal Control and Agent Based Reasoning for Unmanned Aerial Vehicles G. Brambley and M.

We'd have to mosaic these snapshots to build a wide-angle cockpit view. It looks like Curtis Olson has done relevant work in using FlightGear to provide a real time synthetic display for a University of Minnesota UAV project. Since we're very new to FlightGear, I was hoping to get a few pointers/tips on where we should start. Thanks, Karen Nyenhuis - Take Surveys. Earn Cash.

Re: [Flightgear-devel] radials revisited
On 01/29/2007 11:01 PM, Dave Perry wrote: This is exactly the situation that John Denker maintained was an exception to the rule report position as the radial from the station and DME distance. This pilot agreed with John. Actually I have changed my mind about this. A couple of days ago I had the opportunity to ask a couple of TRACON controllers about this. -- They said *all* radials radiate outward. -- They said, quote, The FAA is anal about this. -- If the pilot is inbound on the NNN radial, his heading will be approximately the reciprocal of NNN. -- They said reversing the radial is a rather common pilot mistake. -- They said they would not spend air-time correcting a pilot over this issue, but they would certainly prefer for everybody to use the approved terminology. I'm sorry if my erroneous discussion of this exceptional case confused anyone. As a consequence, we can say that in FlightGear, the --azimuth command-line option is, without exception, not a radial but rather the reciprocal of a radial. This mistake and confused position report was the beginning of a series of mistakes in knowing/reporting the position of his AC that 14 minutes later caused him to fly into a mountain. That's going waaay too far. Could we please stick to the facts? The incorrect utterance occurred at 1104:22. The crash occurred about 20 minutes later. The aircraft was in radar contact for four of those 20 minutes, removing any doubt ATC may have had as to the location of the aircraft. caused him to fly into a mountain. My little brain is unable to understand how this incorrect utterance could have caused this crash, even in part. Nowhere in the cited document does the NTSB attribute any causative role to this incorrect utterance. In general, not every pilot mistake is part of the chain of causation. Similarly, not every controller mistake is part of the chain of causation. This is a very, very important point that commonly comes up in connection with post-crash litigation. Everybody blames everybody else for causing the crash, and they often grasp at utterly irrelevant discrepancies and try to claim a causative role for them. In this case, the pilot flew into a mountain because he failed by a large margin to track the outbound radial. This has got nothing to do with what he said about the inbound radial. He was killed.

[Flightgear-devel] Another scerenio where FG labours (freeze type of thing)
Hi all, Similar to the issue I reported (a few weeks ago) of the 'freezes' when near other aircraft (which Mathias fixed), here is another similar one. My build is osg cvs (updated the weekend) using --enable-sdl. If a prop driven aircraft crashes nose down so the rotating prop gets embedded into the ground, FG will 'freeze' and stutter along at 1fps or worse. It takes ages to gets the menu to react to be allowed to reset (in fact, my mouse disappears a lot during this time). One easy way to replicate this is to use the Spitfire on the runway - ensure brake lock is on, and open up the throttle - the aircraft will tip over nose first, and FG will then show the above problem.

If it can't see any ground intersection below the airplane, it might make sense to return the first intersection above the contact point instead ... then if you do manage to go subterrainian, you won't get stuck there like what happens now.

Thanks, Curt. Hi Curt, [second attempt at posting] I did a UK Class 56 diesel loco for a picture I was working on and you're welcome to that but I didn't need any wagons for the pic so I cant help you there. Perhaps a 'light' engine movement would sufice :) There's a wip image of it at http://www.spatial.freeserve.co.uk/V5/im_Class56.008.003.jpg The model wouldn't be usable in FG in it's current form, as it's made from a combination of SDS, NURBS and Analytical solid objects and it's in RS3D format so I'd have to convert it all to SDS before I could export and convert it to AC3D format. The conversion would take some effort because some of the modelling techniques I've used only work well with the particular object formats I've used, for example, I've used boolean NOT or trim curves to cut holes in surfaces (can't remember exactly which technique I used) but if were to make that surface and it's hole AC3D compatible I'd actually have to model the hole. You can see this in the image linked to above in the grills in the side of the roof - the roof surface is SDS but the holes are boolean/trim-curve cut-outs and the grill 'slats' are analytic cubes. Actually, now that I've thought about it while writing this, I'd probably do the grills with a texture, rendered from the model itself, Anyway, let me know if you want it (it's a UK loco remember, not a US one, so just that fact might cause some confusion among the viewers) and if so, what sort of time-scale would it be needed by.

And I suspect there are more misfeatures in the Linux OSS driver for that particular chip. The OSS driver for it doesn't work at all with teamspeak (8-bit mono again) for instance. Methink the driver whisper lies in user space about the card, or at least not tell the whole truth... The ALSA-driver does the job with teamspeak. Without having ivestigated it, I would guess it recalculates an 8-bit mono stream to 16-bit stereo on the fly. And the Windows-driver probably does the same. It's not a bad audio chip really, but it doesn't support low bandwidth sound streams directly so that has to be done in software somewhere, which may be error prone. - Take Surveys. Earn Cash.
