  The ADF produces a left/right audio signal to indicate the NDB

  with a left track only and one with a right track only.
 
 Correct solution is probably to change the position of the sound source 
 for the left/right sound samples. Erik can probably give better hints.

True, sample groups that are tied to the listener still support a
relative position. So changing the sample to mono, positioning them and
use the same 'mixing' configuration should work.

There is something fundamentally flawed with stereo files anyhow; most
(especially the hardware) OpenAL implementations only support *one*
stereo source which isn't processed in 3d space in any way. Stereo files
also consume two sources (in this case two wasted sources) and with
hardware limits as low as 32 simultaneous sound some people run out of
sources real quick.

Re: [Flightgear-devel] Some More Detailed Scenery

Hi and a Happy New Year,

 So, rather than forking development into many little subprojects, and
 finding ways to better support these forks, we should find solutions, so
 that scenery developers keep joining forces and improve our common
 scenery world (uh, that sounds cheesy, right?).


No, of course it doesn't. One year ago I have compiled some scenery for 
eastern Europe, using Corine and OSM. At the time, I was not quite aware of 
the existing infrastructure and effort to maintain a common database (like the  
PostGis project). Besides, there was the problem of different licenses for 
various datasets. If someone would like to analyse the compatibility of 
various licenses with the Flightgear repo, I'll gladly offer the terrain 
layers for inclusion in a common repository. Also, I can't reliably host the 
terrain file myself, and other options have some drawbacks too. 
Where can I find some documentation on contributing such work?
For future reference, here is the forum link:

Cheers,
Adrian

Hi,

I've written an OpenLayers handler to populate some input fields with the 
cooordinates of a drawn box on the map. The zone has to be defined by first 
clicking on the lower left corner, then on the upper right one. No 
modification has yet been made to the download script, but it should be pretty 
simple from there.
This is the gitorious merge request:

Re: [Flightgear-devel] new Altimeter for Cessna c172p

Hi Stephan,

 Hello everybody,

 I have a new Altimeter ready for the c172p cockpit. However, I have a few 
 questions regarding the panel illumination.

 1. All the current instruments, except the AI (gyro) have illuminated knobs. 
 Should I keep this with any new instrument?

Yes please. It may not be completely realistic, but as we don't have
real cockpit illumination, or a virtual flashlight (!), we've got to
cheat slightly to make the aircraft usable.

 2. I have problems with materials that don't use a texture map. Even when the 
 light-control is off, standard AC3D materials seem tohave a white 
 illumination. The illumination turns orange as the light-control is turned 
 up. I was hoping to replace the grey texture map on knobs with a standard 
 AC3D material.

 Has anyone else experienced such a problem?

I recall a while ago a recommendation from one of our graphics gurus
that it is more efficient to use textures rather than a number of
different objects without texture maps.  I would suggest just using a
texture map in this case to avoid the problem.

 On a related note I noticed that the menu option to change the lat/Lin format 
 has been removed. Given how useful it is to have a decimal degrees read out 
 for scenery development that seems somewhat strange. Was this intentional ? 
 Or is it a regression? I'm thinking it would be better located under HUD 
 properties.

On further investigation, it looks like this was lost a long time ago
in one of the menu re-organizations, and has been left as a
commented-out menu item.

At various times, it existed as a menu item under the File, View and
Autopilot menus, where each selection cycled through one of three
options for /sim/lon-lat-format.

AFAICT it's main relevance is to the HUD, so I've created some  radio
buttons in the HUD Configuration dialog to control this and cleaned up
the commented out menu items in menubar.xml.

If anyone knows of another use for this property, and can think of a
better location in the menu system for controlling it, please let me
know.

2012-01-05 Thread Tuomas Kuosmanen
Just a random thought: does (could) it have both hPa and InHg scale in the
baro window? Would be very practical. Those exist in real life, there sre
just two baro scale windows on opposite sides of the gauge face.
