explicit calls to shutdown_all() which was causing this to be called twice.
This could cause problems with some IO modules (such as attempting to close
an invalid file descriptor the second time.)
a single apt.dat.gz file which is in the native X-Plane format.
To do this I wrote a front end loader than builds the airport and runway
list. Some of the changes I needed to make had a cascading effect, so there
are minor naming changes scattered throughout the code.
I've finished the emigration of the radiostack, and I've also removed it
completely. It turned out that the comm radio is completely implemented in
the ATC subsystem. I've changed the affected ATC files to point
to /instrumentation/com, but I guess that the maintainer of the ATC code
should decide wether to make it configureable, and how.
I also had to change some files in Network and Main. The changes in network
should be obvious, but the changes in Main were a bit suspect. The files
included radiostack.hxx, but they weren't directly depending on
radiostack-hxx. They were depending on other files that were included by
radiostack.hxx. I got it to compile, but I'm not sure if I included the
correct directly depending file.
For the data directory I changed every occurrence of /radios/
with /instrumentation/ with this simple one-liner that I found on the net:
find -name '*.xml' -type f | xargs perl -pi -e
's/\/radios\//\/instrumentation\//g'
Instead of me sending all the files that got changed by this I suggest that
you execute the one-liner yourself. Of course I can not guarantee that this
will work perfectly, but I considered hand editing to be not an option (I'm
lazy). I don't want to test every aircraft to see if everything still works,
I think it's better to wait and see if anyone complaints about broken nav
radios/instruments.
Use a suggested exit method as described in the SDL_Quit man page. (fgOSExit() is still uncalled in both fg_os.cxx (glut) and fg_os_sdl.cxx, which makes these functions kind-of useless.) The other changes are fixes for gcc 3.3.4 warnings.
The caption should already be set when the window is opened. This is
important for some window managers. (KDE's kwin, for example, can store
special settings for certain windows, such as "no border" and "always
on top". KDE uses the window title to determine if a special rule is
to be applied. KDE will be made more tolerant, too.)
After applying the attached patches (based on latest CVS) you should
have a new option available within your version that should also
show up using fgfs --help, the syntax is:
fgfs --min-status={level} --show-aircraft
whereas "level" can be anything between
"alpha","beta","early-production" and "production"
Of course running something like
fgfs --min-status=alpha --show-aircraft
should not return any aircraft right now, as none of the
current aircraft definition files in your base-package is using the
required
<status></status>
tag - but you can easily give it a try by adding something like
<status>alpha</status>
The tag should be placed as a sub-tag within <sim> - so directly behind
the <description> tag would be just fine and straight-forward.
I've added two new debug log types for the instrumentation and systems. They
used to use the autopilot debug log, because I couldn't figure out how to
make new log types. Well, now I have figured it out. ;-)
Don't overwrite user settings from config files.
fgfs had in any case set bump-mapping to false, no matter if this
node did already exist (because it was defined in a config file).
This is a patch to make display list usage optional. They are on by default.
Use --prop:/sim/rendering/use-display-list=false to use immediate mode.
There is also a change in exception handling in main.cxx and bootstrap.cxx

a working state. I still see an anomoly when taking a screen shot from inside
a 3d cockpit, but external (chase/tower) views seem to work well. I also
added a property to control how many screen-res tiles are generated in the
output. Theoretically, you can now generate unlimited resolution screen shots,
or limited only by your disk space and patience.
Today I successfully generated a 20*1024 x 20*768 (20480x15360) resolution
screen shot. If you rendered that at 100 dpi it would cover a poster of
about 17 feet by 12.8 feet.
Good luck trying to display something that big or convert it to anything
useful on a typical PC. :-)
split). If SimGear is configured --with-jpeg-factory, then FlightGear
will fail to build unless this function is present.
FIXME: this is very messy architecturally -- find a better solution,
like passing this explicitly as a callback to the libJPEG class
(SimGear should not have a dependency on FlightGear).
Split up main.cxx into a program manegement part (which remains in
main.cxx) and a render part (the new renderer.?xx files). Also turn
the renderer into a small class of it's own. At this time not really
exctining because most of the stuff is still global, but it allows us
to slowly migrate some of the global definitions into the new class.
The FGRenderer class is now managed by globals, so to get the renderer
just call gloabals->get_renderer()
At some pijt it might be a good idea to also turn the remaining code in
main into a class of it's own. With a bit of luck we end up with a more
robust, and better maintainable code.
this was always only meant to be a test program for the metar lib, but now
that people are referring to it as a means to get metar reports, I think a
usage info is desirable. The list of test ids, on the other hand, isn't
necessary any more. This can still be handled by a Makefile or the commandline.
I'm all for keeping this tool in cvs, however. And also the not-used stuff
therein is a welcome source for how to use the SGMetar class.
A good elevation is critical for proper glide slope modeling. This patch
assigns the average field elevation to any ILS component that doesn't have
a valid elevation.
Also, for an ILS approach, use the GS transmitter elevation for glide slope
calculations rather than the localizer elevation, in some cases this can
make a big difference.
Wouldn't it be better to prepare the whole list of paths (or two
separate ones for Terrain/Objects if necessary) in FGGlobals::set_fg_scenery,
and to pass the vector<string>s to FGTileEntry::load? It doesn't seem to make
a lot of sense to split the path up, modify it, mount it together to one string
again, and then let FGTileEntry::load split it up again.
Here we go:
Main/globals.cxx
================
As fg_scenery is now a string_list, we don't need initialization. Furthermore,
this list is cleared with every set_fg_scenery() call.
ctor: create default dir from fg_root if necessary. Otherwise check all paths
of --fg-scenery/FG_SCENERY: If the path doesn't exist, ignore it. If it contains
a dir Terrain and/or Objects, then only add that to the list. If it contains
neither, then use the path as is.
Scenery/tileentry.cxx
=====================
Trivial: don't split a "base path", but use the given path_list as is.
(I considered a variable name "path_list" better suited than "search".)
Scenery/FGTileLoader.cxx
========================
No more fiddling with sub-paths. This has to be delivered by get_fg_scenery
already.
These change add some code that at initialization time will snap all
localizers into perfect alignment with their runways. It's my experience
that the DAFIF/FAA data reports runway and localizer headings to a level
of precision that is great for making charts, or adjusting your OBS, etc.
But the level of precision of this data can be far enough off to make you
visibly *un*aligned with the runway when the CDI needle is centered.
There are probably cases where the localizer isn't really perfectly
aligned with the runway, or intentionally misaligned to avoid obstacles
or terrain. So I have made this configurable for those that trust the
data more than I do. Just set "/sim/navdb/auto-align-localizers" to
true/false in the preferences file to turn this feature on or off in the
code.
- FG now directly supports Robin's native nav database file format.
- His latest data now separates out dme, gs, loc, and marker beacon
transmitters rather than lumping them all into a single "ILS" record.
- These new data structure changes prompted me to do some code restructuring
so that internally these different types of navaids are all kept as
separate lists and searched and handled separately.
- This structural change had a cascading affect on any code that
references or uses the nav databases. I've gone and "touched" a lot of
nav related code in a lot of places.
- As an added bonus, the new data (and code) adds DME bias so these will
all now read as they do in real life.
- Added Navaids/navdb.cxx and Navaids/navdb.hxx which provide a front
end loaders for the nav data.
- Added Navaids/navrecord.hxx which is a new "generic" nav data record.
- Removed Navaids/ils.hxx, Navaids/ilslist.cxx, Navaids/ilslist.hxx,
Navaids/mkrbeacons.cxx, and Navaids/mkrbeacons.hxx which are all now
depricated.
configure and compile out-of-the-box on a MinGW target:
Use -lSDL instead of -lglut32 on windows builds when --enable-sdl
is set.
Link against alut.dll in addition to openal32.dll.
Replace BSD bcopy() with ANSI C memmove() in a few places. This is
simpler than trying to abstract it out as a platform dependency in a
header file; bcopy() has never been standard.
The ENABLE_THREADS handling has changed to be set to 0 when threads
are not in use. This breaks expressions like #ifdef ENABLE_THREADS.
Replace with a slightly more complicated expression. It might have
been better to fix the configure.ac script, but I didn't know how and
this whole setting is likely to go away soon anyway.
The MinGW C runtime actually does include snprintf, so only MSVC
builds (and not all WIN32 ones) need _snprintf in JSBSim/FGState.cpp
Building on a platform with no glut at all exposed some spots where
plib/pu.h was being included without a toolkit setting (it defaults to
glut). Include fg_os.hxx first.
And when still using glut, glut.h has a bizarre dependency on a
_WCHAR_T_DEFINED symbol. It it's not defined, it tries to redefine
(!!) wchar_t to disasterous effect.
1. The listener is always positioned at the origin.
2. All sounds eminate from the aircraft's model position.
3. Sound positions are relative to the listener location.
my code was accidentally drawing the cockpit twice
in view 0. This patch should fix the problem of
lights not seen through canopies or prop discs.
It was also drawing the lights ( ground and rw )
after the clouds, so they were not obscured by
them.
