[Flightgear-devel] Snow questions
I've implemented the snow shader effect into lightfield rendering yesterday - this looks quite promising already: http://www.flightgear.org/forums/viewtopic.php?f=47t=14755start=165#p155463 but I have a few questions I've come across? I've tried to use /environment/snow-level-m to control the effect initially, but it turned out I can't set that while Advanced Weather was running, even with METAR mode off. I've then introduced my own alternative snowline property that I can test the effect properly, but that's not a particularly smart solution. Basically, I want to be able to set /environment/snow-level-m via the Advanced Weather menu as well while the system is running. Can anyone give me a brief introduction into the logic that controls the snowline currently so that I can decide how to best approach this? Also, I was wondering about changing the snowline dependent if the surface is facing south or north. Do we know in model space where south is, in other words, are the terrain tiles loaded in a well-defined orientation like (1,0,0) points west or so, or is there some unpredictable offset involved? The noise texture seems a very useful technique for all sorts of things - does anyone know a short writeup about what exactly it does (at what scale is noise generated, by what algorithm, ...)? - maybe I can use something like that to get some variation into the apparent fog density and distort the horizon line a bit for a more realistic effect. Also, debugging was unusually tough because since a while ago my console is flooded by messages calculating estimated arrival times after a minute or so and the messages I've been waiting for are lost - is that the AI system (which was actually set to off on startup by property)? Can we get rid of this? Thanks in advance for any help, * Thorsten -- For Developers, A Lot Can Happen In A Second. Boundary is the first to Know...and Tell You.

Also on the FTP site I note the file names STILL have +OSG in them, but they now do not contain OSG headers/libs/dlls ;=() The previous 20120304 contained install\msvc90\OpenSceneGraph... stuff. Yes, I know the msvc100/OpenSceneGraph stuff can be all found in the 'archive.zip' pointed to by the 'OpenSceneGraph' link, but the one thing about that 'archive.zip' is that the folder name 'archive/' is prepended before 'install/'. That of course is no particular problem, but it does mean some 'manual' folder manipulation after you unzip it ;=)) Anyway, thanks again...

Re: [Flightgear-devel] FGbuild for MS Windows
Hi, with some generous help and advice from Geoff, finally got an FG build on windows done, phewww! Using latest git version as of the 15th. But now it crashes on startup :-( Complains about not finding a plugin to read objects from file c:/fg-2.7.0/fgdata/xx from the gitgo. Missing dependency; file path problem, command argument?? any suggestions on where or what to look for? Thanks John -- For Developers, A Lot Can Happen In A Second.

Re: [Flightgear-devel] FGbuild for MS Windows
Hi Geoff, OK. the SG and FG versions were from git on the 15th as well as the fgdata as of last night the 3rd party was the same as you noted. \3rdparty - fgfs-win32-VS100-3rdParty+OSG-20120411.zip Thought I mentioned that in an earlier email. No problem, bears worth repeating to make certain Looking over your comments, it might be my install of the OSG stuff that is causing the problem. Took the easy way of sticking fgfs.exe in with the 3rd party libraries, guessing what is missing is the OSG plugin or a path to it. I'll look there first. Sometimes the error msgs are not very clear to newbies. We'll get there...

Re: [Flightgear-devel] [Rembrandt] the plan
Ignoring the horrible artifacts for a moment, I think we need at least one more mip level on the instrument faces for the 172. Even at that low resolution they are very blurry.

Although the shadows are disabled, the shadow map is allocated in case you want to see them in flight.

Sometimes the error msgs are not very clear to newbies. I keep my working binaries outside of the build folder (C:\Program Files\FlightGear\bin\x64\ for example). If I update OSG or any 3rd-party libs I delete everything in my working bin folder, then copy everything from these folders: install/msvc100-64/OpenSceneGraph/bin/* 3rdParty.x64/bin/* to the folder where my working binaries reside. I haven't had an issue with missing or incorrect version plugins this way. Your directory structure may be a tad different, as I see it is on the new wiki page, but those folders either need to be in your $PATH or their contents copied to wherever you stick fgfs.exe, etc. Hope this helps :-) cheers, Rob -- Better than sec?
