Re: [Flightgear-devel] TerraSync/SVN should be ready to use
On Thu, Nov 13, 2008 at 11:46 PM, Frederic Bouvier [EMAIL PROTECTED] wrote: BTW, are you aware the use of SVN implies that a second copy of each file is kept in a hidden directory, and makes the scenery directory two times bigger than a directory fetched with rsync or ftp ? Yes, svn is approximately double the local disk footprint of rsync. Both svn and rsync use a chunk size that is 1% of that used by FTP. You're still better off with SVN unless you routinely fly at least 3000 km of distance in each 10x10 tarball you download. Without going closer than 300 km to any other area already flown over. Most people will not achieve that level of utilization, especially if they're either choosing routes for scenic sights or for realistic IFR tracks. A note in the documentation is probably a good idea. Anyone who just wants a snapshot of the whole planet for offline flight would be better off retrieving all the tarballs by FTP. Nobody mentioned any plans to turn down the ftp service, and I certainly haven't been expecting either rsync or svn to replace that bulk option. PS. There may be a clever option for subversion that avoids keeping duplicate files for directories that are not currently being modified (like cvs does). But if there is, I don't yet know about it. If anyone comes across such a thing, we should change the terrasync source code. 8-) - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel

Asterisk will start for every call to a virtual frequency one coneference application. THis application has a thread which polls the data from the MP server to calculate the distances between the clients. To put this function one stage above the conference module means to patch Asterisk itself. That is not really portable and I think very difficult... Or just use a common cache file. Btw, I remember you experimented with sending the position data through the asterisk connection, didn't that work? You wouldn't need polling then. Yes, but it is difficult to implement in the conference application. Because every member has his own thread you have much to lock and unlock while putting data in a global structure - and than you have to calculate the distances every few seconds and so on... it seems to be easier to poll the information from the MP server. A streaming connection with a configurable frequency (like the FG protocls) would be better... Also you will have to be a real FG client on the FGMP with the same name on the iaxchannel as your callsign to start up working connections with fgcom3. That is a big advante because all the trolls have start at least a FG multiplyer simulator to chat with fgcom and the Asterisk server admin can tell his users to use realistic calls signs (no relistic call sign (and every time the same!) - no iax account - no fgcom3. But this is in the hand of the Asterisk server admin. The simplest way would be to run a multiplayer server on the same machine as asterisk - that way you could query it as fast as you liked without any hit on the main MP servers.

Re: [Flightgear-devel] How to lower how much scenery gets cached:
A quick question for any of you. Can Flight Gear be used as a database for ground elevation? Could I query it with earth coordinates and ask it to return the local elevation of the ground with respect to sea level? Would this be difficult to implement?

Is it possible to add some memory to get yourself up to maybe at least 512Mb total? If you are running this under linux, there are easy ways to look at your total system memory, how much memory is out in swap, how much memory the FlightGear application is taking, etc. Probably similar tools under windows, but I'm less familiar with system level debugging there.

I don't recall the exact formula ... maybe something like 2*n + 1 (where n is the number of visible tiles.) I don't know if this concept was carried forward to the OSG version ,but you might try limiting visibility and that should reduce the number of tiles being loaded. Regards, Curt.

Yes, it can, though whether it's sensible to do so would depend on what you wanted to use the information for. You can use the properties interface (either by telnet or http) to set a position, then read back the ground elevation - the null fdm is ideal for this. We also have a tool which can load scenery tiles and return elevations - it's far more efficient for doing this in bulk. The values you get are of cource the elevation of the scenery, which may vary from real world values - if that's what you want then you're probably better off reading values directly from SRTM or a similar source.
