[Flightgear-devel] Native-Ctrls UDP packet structure
Hi all, I finally did manage to get some sort of data transfer from a joystick to flightgear through Matlab using Native-Ctrls. I still got some questions remaining. 1. I do see variations in the elevator and ailerons axes in the cockpit of the Cessna, but I don't see these variations reflection in the control surface positions. I checked in the remote browser and none of them get updated. 2. I was wondering if the throttle axes varies from -1 to +1 or from 0 to 1. Right now all the throttle knob does is fluctuate between the two extreme points when I vary the axis on the joystick. 3. I send 0s for all the other properties that I do not want to control. I realize now that it was a bad idea... the aircraft sits frozen (none of the usual JSBsim vibration either) on the runway. I guess I need a way to make flightgear ignore variables I do not want to control. Is there a way to do that? Thanks all!! ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
[Flightgear-devel] JSBSim Crash Animation Handling
I would like to present what i am developing for crash animation
handling, with JSBSim
That exemple is only a skeleton. It use Nasal, and should be tailor made
for the Aircraft.
It is only based on AC_GEAR contact points (CP) definitions, test of
values for each CP and decision or not to start the crash processing (in
the exemple we only use WOW).
Once the crash detected an animation process can be started which look
like "bo105 animation" (in that case everything is possible).
This is only working with FG-9.8
The last CVS modification which activate a Pause on AGL test makes it
impossible. The contact points become unusable.
Nasal exemple as attached document

This may be interacting badly with your local changes, which makes debugging difficult. Nothing in this mechanism should require any of the new code. Also on this subject: I started integrating the RPM-based supercharger attenuation, and noticed that your code added three new engine properties: mp-pascals: Is this needed?

Also, must the units be PSI, or can I change them to inhg? The final name would then be "boost-gauge-inhg" (units go last, and "pressure" is implicit in the units). boost-pressure-inhg: Reading the code, this looks like an absolute manifold pressure, and not a boost at all. Is this a mistake, it looks like a synonym for mp-inhg to me.

Re: [Flightgear-devel] Shadows
Forgive my annoyance, but here are a few more questions. =) First of all, I am seeing a potential problem when the sun is below the horizon (during dawn and dusk) and doesn't cast any shadow onto the ground. Does your code handle this special case at the moment? If so, how? Secondly, do objects with illumination (such as the flame from the f-16's exhaust) disrupt shadows? Finally, is there a potential for this technique of generating shadow to be used on generating the effects of spot lights (eg. landing light, taxi light, logo light, etc.)?

For my usage i need an operational video card with Open GL V2.0 fully operational, with the higher speed. Only the last driver gives that performance (7664). About old drivers i did used it a long time ago without patch first (old linux release) and with patch after (new linux release), with an "other old NVidia Card". (just for the fun i benchmark my old video card and the new one both with the same old driver, the benchmark gave slightly the same performance) You are talking to reduce the performance of my last video card by using that old driver only to make FG running (sorry instead of degrading the video card performance, if choose to reduce the functionalities of FG).

Re: [Flightgear-devel] Shadows
Ampere K. Hardraade wrote: Finally, there is shadow in FlightGear. =) Couple of questions: Do the authors of the aircrafts have to specify the objects that can cast shadow, or is it all done automatically? It's automatic. All sub models of the aircraft (the ssg Vtx nodes) are preprocessed to extract the edges used by the shadow computation. <>On aircrafts that have multiple level of details, such as the MD-11, majority of the objects are made invisible. If these invisible objects cast shadow as well, it might produce huge overhead. Is your code intelligent enough to leave these invisible objects out of the calculations? This case is handled, I check the value of the ssgSelector in the object tree so select and range animations are correctly rendered. <> Unlike other aircrafts where everthing is put into a single mesh file, the A380 model is split into multiple files to allow meshes of different format to work together. Does shadow work on the A380? It should be ok if all your files are tied to the aircraft branch in the scene graph. <> Finally, what is the minimal graphic card requirment to be able to see shadow? It's hard to say, I just changed my graphic card but with the previous one - a Ti 4200 - I was not under the impression that I was fill rate limited. But the cpu has some impact too. There is a few computation needed to determine what to draw. The result of this computation is cached and updated when needed (when the sun moves or when an animation is doing a rotation for example). At the end it all depends on the model used, the Concord has like 30.000 polys, the c172p has less than 2000 polys. Dave Culp wrote: Does the canopy frame cast a shadow on the cockpit interior? Yes ;) Do transparent surfaces cast shadows? ( I don't mean to be annoying, just curious. This would add a whole new level of realism to 3D cockpits :) I didn't do anything special for transparent surface atm. So yes they cast shadows but I can't tell if this is a good or a bad thing. Martin Spott wrote: Do you need _any_ changes to the aircraft models (like Melchior did for the BO-105) or does it just work right out of the box with the existing models ? It's a bit early to reply that question. Perhaps we need to make the current model shadows conditioned by a property so that we have either the volumetric shadow or the one from the model. Anyway, this looks really great and I think your effort is definitely worth being added to FG, maybe switched off by default - for users like me :-) with a property to toggle it on demand Yes of course it will be optional ;) Harald. ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d

Yes, more or less - PistonEngine.cpp seems to be seeing it, and you can see the boost going up and down with the throttle setting, but the power isn't which seems to eliminate the typo theory. > My only suggestion is to look harder for a typo or somesuch; make sure > the property you are setting is the one you are reading.

Well, I'll just have to eliminate all possibilities one by one. I think PropEngine.cpp is a likely candidate, but I haven't had time to look in depth yet.

I think that a design philosophy that incorporates backwards compatibility is A Very Good Thing. It's harder to start with but makes things much easier and more flexible in the longer term.

Re: [Flightgear-devel] getting the best perfo with FG

The FG version is the one Fred put on a webpage with the process splash screen. I had the same performances with the official 0.9.8 release.

Finally, there is shadow in FlightGear. =) Couple of questions: Do the authors of the aircrafts have to specify the objects that can cast shadow, or is it all done automatically? On aircrafts that have multiple level of details, such as the MD-11, majority of the objects are made invisible. If these invisible objects cast shadow as well, it might produce huge overhead. Is your code intelligent enough to leave these invisible objects out of the calculations? Unlike other aircrafts where everthing is put into a single mesh file, the A380 model is split into multiple files to allow meshes of different format to work together. Does shadow work on the A380? Finally, what is the minimal graphic card requirment to be able to see shadow?

[Flightgear-devel] need help for convertion(importing) fron MS FS into Flightgear
Hi every one: any one can give me some hint about how to run the MS FS models under flightgear? I have searched for long time, It is said Wolfram's manual can help, http://home.t-online.de/home/Wolfram.Kuss/,this websit looks something else and also is Germany I don't understand.

The ordering of the elements in the .ac file is important, or as Jim said it can be done with an tag. Sometimes you can get away with just one tag, and sometimes you will need more. In addition to instrument lighting, the Hurricane also has 'floodlighting' of the panels and some 'stray' lighting around bits of the cockpit. Not real of course, just a tad of emission as required. This ordering thing is something we aircraft designers just have to get our heads around - there's no easy way, and when it comes to transparency ...

Re : Re: [Flightgear-devel] getting the best perfo with FG
Hi again people, problem solved ! :D I've just recompiled the latest cvs of plib, simgear and FlightGear, turned on the threads flags, and now I have a FG running up to 60 fps (i have forced the synchro with the vertical refresh). Cuold somebody explain me the way to tune FG options to get the best perfo ? visibility, threads, dynamic terrain loading ...
