Re: [Flightgear-devel] Ridge lift in south hemisphere
jean pellotier a écrit :
hi, yesterday we were near the Kilimanjaro (HTKJ) and up to reach the
top with a c172, we tried to use the lift given by ridge lift, but it
was always 0.
I tried to start at Quito (SEQU) and ridge lift get elevation values
only once in north hemisphere.
it seems that:
(globals-get_scenery()-get_elevation_m(SGGeod::fromGeodM(
SGGeod::fromRad(probe_lon_rad[i],probe_lat_rad[i]),
2), elevation, 0))
in environment/ridge_lift.cxx is always false in south hemisphere, an
can't report the ground elevation
The responsable was the test for the pole position, to avoid a division
by cos(lat) =0, here's a patch addressing this issue, if someone can
have a look and commit, thanks.

The huge difference is that it also works for btg and with some knowledge about the internals of the model loading process also for stg files. The tool is aimed at people working on scenery and willing to see how their scenery modifications will look like. The can do so now without starting flightgear. This seems to work for me. This is a basic version of that tool that might grow it there is a need. I hope to include more flightgear internal scenery loading stuff so that you can at some time also load aircraft models an see if the static parts animations/transforms/postprocessing steps are as expected without the need to start the whole simulation. Loading aircraft/building models from the .xml file would be an awesome feature. So far so good. You need to set the environment variable FG_ROOT like you should have in flightgear. And then for example load a btg.gz file of your interrest :) Problems and suggestions to me :) Greetings Mathias Thanks Mathias... It would be nice if an unset FG_ROOT would post a better error message than: $ fgviewer terminate called after throwing an instance of 'sg_io_exception' Aborted It would be even nicer if it compiled in the --datadir= default from configure. :) But great first step!

Background: the default weather-scenario is METAR and if --disable-real-weather-fetch, a fake, hard-coded METAR is interpreted which overrides the given options for visibility and ceiling. Hi Torsten, Thanks for the quick reply, that works and I can fly IFR now :-) However, when real weather is disabled and the user specifies weather conditions on the command line, would it not make sense to incorporate those into the fake METAR at startup? Since you say that this is a fake, hard-coded METAR, I can't see what else this could break? Cheers - Dave My first thought was specifying initial conditions in any of --disable-real-weather-fetch --visibility= --ceiling= should imply environment/weather-scenario=none However perhaps Dave's idea of generating a metar to match the specifications is better. How about this? --metar=27012KT 2SM OVC1000 15/14 Q1001 NOSIG It will set weather-scenario to METAR and disable real-weather-fetch. Needs just a little coding and gives some flexibility. But it probably is not very intuitive for the average user. And the robustness of the METAR parser has to be tested, but that's probably a good idea anyway. I'd really like this options, but I am used to reading a METAR, so my vote does not really count ;-) Torsten -- Register Now for Creativity and Technology (CaT), June 3rd, NYC.

I'd really like this options, but I am used to reading a METAR, so my vote does not really count ;-) I like the idea of being able to pass in arbitrary METAR strings. That would allow a person to easily fly with interesting weather copied from some other location or time. Or even we could setup challenges like fly this approach with this weather, etc. Keep in mind that we estimate cloud tops for METAR weather, so whatever we do shouldn't prevent someone from customizing cloud top altitudes and wind layers from within FlightGear or through the property interface.

[Flightgear-devel] Question about od_gauge
I'm investigating the possibility of ripping out the horrible undocumented special-instrument hack that the KLN89 uses, and using the owner-drawn gauge that the weather radar uses instead in order to render to a texture and become a normal instrument. However, I've got a query about the od_gauge, currently wxRadarBg::init contains this code snippet: FGInstrumentMgr *imgr = (FGInstrumentMgr *)globals-get_subsystem(instrumentation); _odg = (FGODGauge *)imgr-get_subsystem(od_gauge); _odg-setSize(512); where it obtains a pointer to an FGODGauge class from the instrument manager. This is the only point in the code where any instrument obtains a pointer to the od_gauge. My question is, is it safe for the KLN89 to also obtain a pointer to the same FGODGauge instance in this manner and then use it, or does an extra instance of FGODGauge have to be created first?

[Flightgear-devel] Start up Problems
Hi to All How can one check what libraries are being used when your run fgfs ? Also how does one select the best ones?

Re: [Flightgear-devel] Start up Problems
1. Is your graphics driver the proprietary one? 2. If above is Yes, then you have a graphics card that's not powerful enough. If you're running FG in the both heads, try running it in a single head only. Otherwise, if question 1 is No, install the proprietary NVIDIA driver and try again.
