Re: [Flightgear-devel] Total Energy instrument - Was Instrument headaches
If I was able to create a Total Energy Tube module it still leaves me without a way to perform calculations and logic that are vario specific. From what I've seen from googling this stuff it looks like the TE vario is midway between a standard vario and a netto vario in capability. It might be easier to calculate backwards from the netto vario. A TE vario would show the same value as a netto vario except for a min sink rate correction?

Perhaps something relating to the screen capture is reseting the mouse position? Sounds like you might be onto a subtle bug under these specific circumstances. You could also turn on the HUD and instantly see what happens to the control positions. Yes, the controls slew very far.

Re: [Flightgear-devel] screen capture causes loss of control
What happens if you: start FG, display the hud, put the mouse into control mode, make a half deflection of the control surfaces, so that none of them hit their end-stops, and then hit F3? Do the controls move back to their centered position or do they end up randomly placed? When I hit F3 the cursor goes to the bottom-left of the screen. The ailerons and elevator are displaced. If I find the new neutral position and right-click three times to re-enter control mode, then the cursor re-centers. So, F3 causes the cursor to displace very far. When the screen capture is complete the model has already started tumbling.

Re: [Flightgear-devel] AIManager and AIBase
I intend to use FG as a viewer. I have an application that manipulate aircrafts, boats and more, and I'd like to see them living in a 3D world. I saw that in FG there is an AIManager that can do what I want. If I've understood its function, it manipulates AIBase objects which have a position and an attitude (that's all I need). I then have to create AIBase objects corresponding to the entity living in my first application and then refresh properties of AIBase objects. * Is this possible ? I think I will integrate this in FG code... I haven't seen this done yet, but it seems plausible. So far we have only used the descendant classes of AIBase so that we get a basic FDM that allows the objects to move by themselves. If you will be providing for the movement of these objects using some other process, then you won't need the descendant classes. I think this will work, but you may have to look through the AIManager to see if it can handle AI objects that don't use a descendant class. Some small changes might be needed. * If I'm right I won't need any FDM. What should I do in FG code to remove/disable this feature ? I believe a null FDM is possible? If not, then the UFO FDM might be the simplest solution for you. * Is it possible to attach the viewer on an AIBase object ? If it is, how can I do it ? Don't know. The AI objects report their position to a property, so the location of each object is known. If you are providing the AI FDM from another application then you already know the AI object's location and orientation?

There is some here: http://www.seedwiki.com/wiki/flight_gear/ai_model.cfm?wpid=141766 but a problem with rendering XML in wiki makes them hard to read. Right now there are two instances where AI objects are created on-the-fly. One is in the submodels manager (see /source/src/AIModel/submodels.cxx). These are ballistic AI objects the emanate from the user airplane. Currently this is used for contrails, smoke, flares, tracers, etc. The other instance is Durk's Traffic Manager, which creates AI aircraft based on a schedule, and creates flightplans for them. This provides ongoing airline traffic.

[Flightgear-devel] thunderstorm, lightning
Just checked in to CVS is a demo of an AI thunderstorm with lightning. Some notes: 1) To run this just use the AI scenario called bigstorm_demo.xml 2) You will see a 37000 foot thunderstorm over San Francisco, with lightning flashes. It looks best if your visibility is set to at least 10 miles. Even though the lightning's emmissivity is set to maximum, it will be attenuated by the visibility value. 3) The lightning is triggered by a boolean property, environment/lightning/flash, which is controlled by code within AIStorm.cxx 4) The 3D model, bigstorm.ac, has a lightning object that is selected on whenever environment/lightning/flash is true. 5) The lightning is also attenuated by the rain, so the rain object is set to turn off whenever environment/lighning/flash is true. There might be a better way to do this, but I don't know what it is. 6) This is a first-cut at lightning, and any further development will depend on the possibility of integrating the new clouds code, so I don't know where this will go from here. 7) It would be easy to add triggers for rain, turbulence and St. Elmo's fire, based on the user aircraft's distance from the center of the storm. On the other hand, why model things you are never supposed to do (like crash)?

These calculations are already in David Luff's AI Traffic code, and it was partially adapted to the AIAircraft code by Durk Talsma.

How did you made that ? Is it a scenari object inserted in the .stg or a run time generated poly from a text string ? I made a simple 1000m long rectangle to form the sign.

I put it in the .stg file: OBJECT_SHARED Scenery/Objects/e000n40/e007n49/sembach.ac7.855 49.513 500.0 0.0 It hovers about 200m over the terrain.

Re: [Flightgear-devel] City signs
http://home.comcast.net/~davidculp2/city_sign.jpg It's easy enough to do using the date from GNS (http://earth-info.nga.mil/gns/html/) the biggest quiestion is how to generate the signs - imagemagick could be used to generate a texture to add to a standard model (and an appropriate xml file could be created at the same time to select it) but that would result in insane texture usage. A better way may be to generate the letters seperately, and add those to the scenery (not unlike a variation on the hollywood sign). That sounds interesting. Also, I wonder if the HUD could generate and place text strings instead? Here are possibilities: 1) Allow each .stg file to have one 256x256 texture, hand made, containing the names of the biggest 8 (or 16, or whatever) towns. The signs and their associated .xml files would also be individual and hand made. 2) Jon's hollywood sign method, where the signs are autogenerated using individual letters. 3) Make a text animation (I'm guessing this doesn't exist yet?). 4) Have the HUD autogenerate tags that would appear superimposed over the appropriate coordinates. Of these, number 1 is available now, in concept, although people will have to make the signs. I'm willing to make a set for SFO.

Re: [Flightgear-devel] City signs
As I'm very visually challenged, a sign in the air over an airport saying KJFK 2.5 miles or some such would be a big help finding my way around. Identifying particular buildings in the air would be nice too. (Golden Gate bridge, Washington Monument, landmarks like large cemetaries and parks). I'd love to work on this eventually but that'll probably never happen at the rate I'm going. 8-( Something like this? http://home.comcast.net/~davidculp2/tourist-sign.jpg Perhaps something similar could be used to mark restricted airspace. Something especially useful would be signs for those features found on vfr charts. That should be easy to do, provided the areas are built by hand, like the current buildings and bridges. They could also be toggled on/off with a key binding for airspace marking (seperate from the key binding for city names or tourist signs). It would be interesting to make a terminal control area also. I could do all this, but I would need a sectional, an area to work on (SFO area?), and some assurance that I'll get the key bindings and that the work won't be for naught. Perhaps the signs can be turned on/off with various levels as the log messages are? I think we could use properties for each type of sign, i.e. /sim/signs/cities, /sim/signs/tourist, /sim/signs/airspace, etc. The properties could be set on at your command line, or startup script, and controlled at any time with a key binding. Is US government information on public charts available for use? How is this 'common knowledge' and US government sources impacted by GPL and other licenses?

[Flightgear-devel] FDM freeze
Lately I've been flying around German terrain and have been getting an FDM freeze at seemingly random occasions after flying for ten minutes or so. Here's a screenshot of the freeze: http://home.comcast.net/~davidculp2/fdm_freeze.jpg The user airplane is frozen, but other things keep running fine. The AI aircraft keep going, as does the clock, frame rate, GUI, key bindings, mouse. It looks like just the FDM froze. Anyone else getting this?

[Flightgear-devel] Crash detection (was FDM freeze)
We should probably come up
with some kind of standard way for the FDM to signal to the rest of
the simulator that it has detected a collision and stopped.
I agree it's time for crash detection and handling. I just added a basic
version to my OV-10 sim (can't have public users wallowing around
underground, wondering what to do now :) One decision to make is what the
handler should do once a crash is detected. I have it calling the reinit
code in order to reset the sim to the starting position (below), while others
may prefer to have the sim close after a crash, or perhaps display a
crash-splash screen and/or console warning.
// force a sim reset if crashed (altitude AGL 0)
if (get_Altitude_AGL() 0.0) {
SGPropertyNode* node = fgGetNode(/sim/presets, true);
globals-get_commands()-execute(old-reinit-dialog, node);
}
The above went in JSBSim.cxx because I couldn't figure out where to put it so
that all FDM's could have the same crash detector/handler.

It works fine on the ground, but about 10 seconds after takeoff the 3D side
views of the aircraft's engine/wing go away and never come back. I check
through the property browser and all the values look unchanged. It seems
like the internal boolean value must have changed, but the property browser
does not indicate a change (even after a refresh of course).
Any idea what causes the view to change by itself after takeoff?

Re: [Flightgear-devel] Crash detection (was FDM freeze)
If you want to do push-mode handling with an FGCommand and make it settable by the user, you can have the command call (or be) a Nasal script that can be assigned by the user (e.g. globals.crashHandler = myFunction). Or have it indirect through another FGCommand binding found in the property tree, etc... Which reminds me, I'm using the command old-reinit-dialog in my crash handler, but I can't find where this is defined. It's not in FGCommand, so I assume it's a nasal script? I'm not sure what node should be provided as the second parameter. I'm using /sim/presets, is that what's expected? I like the idea of a global crash handler script, but I don't know enough about nasal to write one. How would it be called from within the code?

I finally took the easy way out and changed the airborne clip plane distance in renderer.cxx to 0.5, rather than 10. That solves my problem, but don't know if anyone else would like that move The issue would only be related to the width of the Z buffer. I was running a Voodoo card at the time I set up this feature where the depth buffer was cleared and reset between the scenery and the cockpit rendering. This may still be an issue for some current hardware configurations. You'd have to do the math to see what the functional far plane limitation is at 0.5m in order to anticipate what will and will not work. Visually, the problem will appear as oddities on the horizon due to depth test errors. Thanks Jim, I haven't seen any artifacts on the horizon, so it looks like setting the near plane to 0.5m works OK for me. FWIW, I'm running on nVidia MX-440.

cart = FGLocation(lon, lat, alt+slr);
}
double cart_pos[3] = { cart(1), cart(2), cart(3) };
bool cache_ok = prepare_ground_cache_ft( State-Getsim_time(), cart_pos,
groundCacheRadius );
if (!cache_ok) {

\n);
cout altitude = alt endl;
cout sea level radius = slr endl;

I know it works fine in the air (I've been using it for a couple days while
trying to recreate the error conditions), but what happens if you get a bad

Re: [Flightgear-devel] After crash , Restart ?
I believe you are seeing the results of a new capability that Dave Culp
added to JSBSim recently.
Aaah, I sense something: This might be a means to automagically
re-incarnate crashed AI aircraft :-)
Actually I added the reset-after-crash to my OV-10 sim because it will be used
by the public, and they will crash often and not know why the crashed
airplane is floating under the surface of the earth. I added it to JSBSim,
thinking that nobody else wanted subterranean floating airplanes. Here's the
code location so you can remove it:
See source/src/FDM/JSBSim/JSBSim.cxx in the function named
copy_from_JSBSim(), at about line 848:
// force a sim reset if crashed (altitude AGL 0)
if (get_Altitude_AGL() 0.0) {
SGPropertyNode* node = fgGetNode(/sim/presets, true);
globals-get_commands()-execute(old-reinit-dialog, node);
}
It uses some pre-existing reset code that I found bound to a key in
keyboard.xml. It seems to work well here, although the report of
the /fdm/jsbsim property node being cloned after every reset is a problem.
You can comment out the code completely, or if you need lat/lon for the crash
site you can add that as console output in the above block of code.
I'll look into the node cloning today if I get a chance.

Re: [Flightgear-devel] After crash , Restart ?
Before I get too far on the property node cloning thing I want to make sure this isn't a feature rather than a bug. Does anyone want there to be old /fdm/jsbsim property nodes kept around whenever fgInitFDM() is called? As background, when the sim is reset using this: globals-get_commands()-execute(old-reinit-dialog, node); the old instance of the FDM is destroyed and a new one created in fgInitFDM(). If this is a JSBSim FDM, then the property node /fdm/jsbsim stays and a new one, called /fdm/jsbsim[1] is created. This happens again at every reinit. This is a problem because some instruments are tied to properties in /fdm/jsbsim, so after a reset they are tied to inactive properties.

[Flightgear-devel] crash handling options for JSBSim in FlightGear
Just checked in a JSBSim.hxx and JSBSim.cxx to JSBSim CVS that makes crash handling user-configurable. The default behavior is the current subterranean flying behavior. If the user sets the property /sim/pause-on-crash to true, then the sim will pause on crash, which is the same behavior Yasim has, so this should be the default for FlightGear. If the user sets the property /sim/reset-on-crash to true, then the sim will reset on crash. As for the /fdm/jsbsim property cloning problem, this has been around for some time now. Any reset of FlightGear while using a JSBSim aircraft will cause another /fdm/jsbsim node to be created. I've tried stopping that but have had no luck. There are several people using properties from /fdm/jsbsim to drive instruments and they are possibly used in some nasal scripts, so this problem breaks some of their panels, and maybe more things.

Anyone know the altitude of the approach lights in FlightGear? They should be the same as the threshold, about 13 feet. They seem to be much lower here, so they're covered by the light structures. The altitude of the approach lights vary based on viewer distance (and/or altitude?) because otherwise they would end up underneath the ground under certain circumstances. May be the approach lights should be shifted by that 13ft, and additionaly moved above with the distance to them to avoid Z-buffer races? That sounds good, but I don't know where to start on that.

Re: [Flightgear-devel] suggestions/questions regarding multiplayer
So the question is: How can I easily calculate the distance and how
many nautical miles are out of reach (thinking of e.g. radar systems)
?
You can compute distance at an altitude using SimGear functions
Ack, don't even *think* about doing the math in a GIS datum.
I agree. You don't need overkill here. A simple check of the bounding square
should work fine. Something like this:
/* Check if position 2 is within a square of side R nautical miles that has
position 1 at a corner. This is a fast approximation of checking the distance
between them, avoiding the use of trigonometric or sqrt functions. This
assumes latitude in the range (-90,90) and longitude (-180,180).
*/
bool IsWithinRMiles( double lat1, double lon1, double lat2, double lon2,
double R ) {
double nm_per_deg_lat = 60.313;
double nm_per_deg_lon = 60.109 - fabs(lat1 * 0.66788);
double lat_diff = fabs(lat1 - lat2);
double lon_diff = fabs(lon1 - lon2);
if (lon_diff 180.0) lon_diff = 360.0 - lon_diff;
if ((lat_diff * nm_per_deg_lat) R) {
if ((lon_diff * nm_per_deg_lon) R) {
return true;
}
}
return false;
}
This should be good enough for deciding if object2 should be visible to
object1, as long the range you're checking for isn't too small. I would use
20 nm for a visibility test.
To get a more accurate distance check (for instance, radar range) you'll need
to call a sqrt function in the test:
if ( sqrt( (lat_diff * lat_diff * nm_per_deg_lat * nm_per_deg_lat) +
(lon_diff * lon_diff * nm_per_deg_lon * nm_per_deg_lon)) R) {
return true;
}
To get even more accuracy you can use trigonometric functions in the
nm_per_deg calculations (see AIModel/AIBase.cxx for the feet_per_deg
formulas).

Re: [Flightgear-devel] T38 and other aircraft xml files overwrite scenario settings
Today i found out, that using the T38 overwrites other scenario settings which are set in the preferences.xml file. It's been like that for over a year. Scenarios should never be set in the aircraft's xml files. Unless the aircraft is demonstrating an AI capability. Hunter/hunter-2tanks-set.xml: scenarioship_demo/scenario OV10/OV10-set.xml: scenariothunderstorm_demo/scenario Thunderstorm and weather radar demo T38/T38-set.xml: scenariorefueling_demo/scenario Refueling and air-air radar demo sgs233/sgs233-set.xml: scenariothermal_demo/scenario Thermal demo The reason to remove them is, that it's not a good idea to set them in the aircraft files when they overwrite other scenario settings that are set in the user specific preferences.xml file. Unless the user(s) aren't aware of the capabilities demonstrated in this way. Imagine that someone wants to use the sgs233 glider and fly around over the Alps. What does he do? He will create a new scenario demo file to have thermals over the Alps and Not in my experience. What he'll do is complain that FlightGear doesn't have any thermals and that it sucks compared to any other sim. Why does someone want to have thermals over KSFO when he wants to fly over the Alps? That makes no sense. See above. Is it possible to make flightgear be able to use more than one scenario demo file at the same time?

Re: [Flightgear-devel] Free simulator of the Frecce Tricolori aerobatic jet
Since the MB-339 PAN is an on-going project, we plan to release an improved version of the aircraft (with smokes?). We have smoke/contrails now, but they need a lot of work: http://home.comcast.net/~davidculp2/contrails.jpg They look OK from some angles, and look bad from others. I tried to add a smoke generator to the OV-10 model (The real OV-10 can inject oil into the right exhaust stack to make white smoke), but it doesn't look good enough to use. The present system makes smoke/contrails by releasing AI objects rapidly. There are three problems with it now: 1) Orienting the objects properly. Only applies for long (i.e. cylindrical, rectangular) models. 2) Matching the release rate to the airplane's speed. 3) Making a smoke model that merges well with the others. I've heard (on this list) that this may be a plib limitation. It may require the use of a different visual model, like billboards or particle fields. On the other hand, maybe a whole new tactic is needed.

Re: [Flightgear-devel] Re: [Flightgear-cvslogs] CVS: FlightGear/src/Main renderer.cxx, 1.27, 1.28
So what basically happens now is that at the (startup) airport the AGL would be reported correctly, but once the terrain elevation increases the reported AGL won't change (like in real life). This sounds more like HAA (height above airport) or HAT (height above touchdown). Height AGL should be the current height above the ground directly below the aircraft. Height AGL should change as the terrain below the aircraft changes.

[Flightgear-devel] lightning
Currently, in CVS FlightGear, it's possible to place an AI thunderstorm in the FlightGear world which has both turbulence and lightning. See the AI scenario called bigstorm_demo.xml. The turbulence is controlled by each instance of the thunderstorm, so you could have several storm AI entries, each one defining an area of turbulence within a specified diameter and with a specified strength. (It's hoped that you'll define the turbulence diameter to correspond to the visual model's diameter. There is no way for the AIStorm object, which controls the turbulence, to automatically know the diameter of the 3D model. ) The lightning however is controlled from one property, environment/lightning/flash. Because of this, if you have more than one storm they will all flash at the same time. I was thinking about changing this so that each instance of a storm will have its own property to be used as a flash trigger, however it would be best if the flashing could instead be completely a part of the 3D model animation, with no external trigger needed. All you experienced modelers, please tell me, is this possible? Can you set a piece of a model to flash somewhat randomly using only XML animation code?
