[Flightgear-devel] C++ module for VoIP / realtime voice: How to begin
Hi all, I wan't to code my external perl client for fg_sqawk (see http://squonk.abacab.org/dokuwiki/fg_sqawk) as an module for Flightgear. The problem of the external module is, that it uses the external protocol to get the state of a predefined PTT key. This can only be done once a second. The next problem is the acceptance of such an external module. For non-devel users it is quite not easy to get all the needed libraries up and running. For the future use it might be easier if the client module is written as a C++ module and can be optionaly compiled with the binary. My problem is (not only my worse C++ knowledge - it is 10 years ago I wrote my last lines of C++) that I don't know how to start this: - how do I insert a keyboard hook for the PTT key? - how do I get properties from the internal property system? - where in the source tree should I put my module sources? I would like to touch preferably as few as possible of the FG code to get this working, but how do I do this? Can anyone give me some hints about that?

The cliffs were spectacular ;) Here is an Atlas picture from another user: http://pics.ww.com/d/48167-1/fgfs-altproblem.png I don't know if/how far the problem area extends further to the east. There is also a lake at N60.19 E15.10 (mpmap coordinates) that has its surface at -580ft in FlightGear. There could be more such strangeness but this is what I've found so far. It would be nice if someone who has the raw data handy could check whether it too has problems in this area or if this is something that went wrong in the world scenery generation. There are a couple issues that could be happening here. The SRTM data ends at +60 latitude. So from that point on up to the north pole, we have to use a different data set which off the top of my head might be the GLOBE 30 arcsec data set? SRTM also pots out a global 30 arcsec data set which might have the regions outside of +/- 60 latitude covered from other data sets ... can't remember now off the top of my head. There is a point (maybe +62 latitude?) where FlightGear switches tile widths. This seemed like a good idea at first (and it is for a couple reasons), but the tile boundaries at this division are not handled correctly in the code so you can see some missing triangles. Generally, if altitudes are just plain wrong, we would need to go back and check the source terrain data ... although there may not be a quick/easy solution.

It may be that this is actually due to the srtm data itself. I downloaded the V2 3 arcsec srtm data for the British Isles region to have a look at it in Grass and the N60 'tiles' appear to be both incomplete and incorrect. They are incomplete in that they do not cover a full 1x1 deg region - the width (E-W) is ok but they only seem to cover about 2/5 of the N-S (lat) axis. The data for this strip appears to be incorrect in that areas of sea are shown as land, albeit with lots of small lakes. I've attached a small screen grab of a section of a grass display.
