CameraGroup supports cameras opened in different windows or in the
same window, with flexible view and perspective specification.
Clean up mouse click handling via osgViewer. Don't let any camera
"have focus;" this forces events to be reported in window coordinates
and simplifies life. Don't use the osgViewer::View::requestWarpPointer
method; instead use our own code which only deals with window
coordinates.
Make glut and sdl versions work with CameraGroup too.
I thought that this would fix the "black hole in the sky" problem,
which turned out to be caused by an OpenSceneGraph bug. Nevertheless
it is a simplification.
* experimental clean-up / reduction on two of the FG headers:
(I'm going to await feedback on the developers list before doing more of
these, to avoiding going over files multiple times, but in principle it
seems pretty straightforward.)
* final fixes for SG_USING_STD removal
- this exposed a bizarre issue on Mac where dragging in <AGL/agl.h> in
extensions.hxx was pulling in all of Carbon to the global namespace
- very scary. As a result, I now need to explicitly include CoreFoundation
in fg_init.cxx.
- change SG_USING_STD(x) to using std::x
SimGear change. It changes all the SG_xxxx to be the 'real' includes, and gets
rid of many #ifdef SG_HAVE_STD_INCLUDES. As an added bonus, rather than
replacing 'SG_USING_NAMESPACE(std)' with 'using namespace std', I just fixed
the small number of places to use std:: explicitly. So we're no longer polluting
the global namespace with the entire contents of std, in many cases.
There is one more 'mechanical' change to come - getting rid of SG_USING_STD(X),
but I want to keep that separate from everything else. (There's another
mechnical change, replacing <math.h> with <cmath> and so on *everywhere*, but
one step at a time)
PLETE_FUNCTIONAL from SimGear and FlightGear.
As a result, SG_HAVE_STD_INCLUDES is now *always* set, so I will get the boring
fixes for that done, but separately. I'm still auditing the other things in comp
ilers.h - there's a lot that can die now BORLAND is gone.
- remove the OSX_BUNDLE crap *I* introduced years ago - we're always a a bun
dle on Mac now.
- fix up the default fg-root on Mac to be FlightGear.app/Contents/Resources/
data - i.e the location used by the macflightgear.org distro, and indeed the obv
ious 'correct' location. Not sure why I didn't use that in the first place, back
in the day.
- remove the CPSForegroundEnable hack. For one thing, we're a bundle and don
't need it, and for another, osgViewer on Mac does the same logic using a newer,
public API rather than a hack into the OS.
- remove the strange logic for doing fgOSInit 'early' (in bootstrap rather t
han main) when running from the command line on Mac; again this is obsolete, and
no one seems to know why it was ever necessary. I guess it was an interaction w
ith SDL when running without a bundle.
- (not Mac related) remove obsolete code bracketed by ENABLE_PLIB_JOYSTICK a
nd USE_GLIDE (neither of which are ever set, even from config.h that I can see)
in main.cxx
Various other patches that have been lingering around for a while:
* Moved trafficcontrol.[ch]xx from the Airports directory to ATC, where
it really belongs.
* AI aircraft will request startup clearance, and ground control will
approve.
* Starting AI Aircraft will be pushed back to a predefined holding point
on the ground network, and wait a while before taxiing out to the runway
- drop unused parts (MouseQuat/GuiQuat)
- move "old-reinit-dialog" fgcommand to fg_command.cxx under new name
"reset" for now. (May later get merged with fgcommand "reinit".)
- move reInit() to fg_init.cxx: This was used by Shift-Esc and
Menu->File-Reset (via fgcommand "old-reinit-dialog"). We have already
a similar function fgReInitSubsystems() in fg_init.cxx, so these two
functions will probably get merged later.)
- don't allow to do that from any XML file. This is to prevent malign
code from writing a new fg-home in ~/.fgfs/autosave.xml or other files
in ~/.fgfs/.
After the changes that moved the GUI and HUD to a slave camera, the
texture-based fonts wouldn't display. The main fixes here are making
sure that the TXF textures are all loaded into the font cache early,
and explicitly setting the active texture unit in the GUI / HUD
drawImplementation.
Switch to defining PU_USE_NONE and providing our own callback
functions to pui for "get window" and "get window size." A new
WindowSystemAdapter class assigns ID numbers to windows for the
purpose of identifying them to plib; the window size can be extracted
from the osg::GraphicsContext class in all the different
implementations (osgViewer, glut, sdl).
Implement a GraphicsContextOperation that runs code in a particular
graphics context, perhaps in another thread, and provides an
isFinished() method to test if the operation has finished. This allows
us to initialize plib PUI properly if there are multiple graphics
contexts without using fgMakeCurrent(). fgMakeCurrent() can't work in
multi-threaded OSG configurations.
Eliminate fgMakeCurrent() and all its uses, either by using
GraphicsContextOperation or by seeing that it is not necessary.
Attach the GUI camera as a slave camera.
Don't manipulate the OSG state in the drawImplementation() functions
for SGHUDAndPanelDrawable and SGPuDrawable; it's not needed.
on the '*'-key, but allow to cycle it by setting
/sim/rendering/on-screen-statistics to "true"
- move that function to the Debug menu (no more key assigned!)
- add "print-statistics" menu entry
From Till:
i started the project at the end of february with a simple idea: move all
3d-model loading to the DatabasePager-thread. my first attempts looked
promising, though they were a little too optimistic (or naive?). the patch
has evolved a lot since.
currently it does the following things:
1. revive SGModelLib, move functions for xml-model-loading there
2. replace all calls to sgLoad3dModel with calls to either
SGModelLib::loadModel() or SGModelLib::loadPagedModel()
almost all models will be loaded by the DatabasePager. the few exceptions are:
your own plane, shared models in scenery, random objects, AIBallistic models.
3. simplify mode-loading functions (avoid passing around fg_root)
4. avoid supurious MatrixTransform nodes in loaded models
5. fix some memory leaks
$ fgfs --version
2.0pre-20080314
FG_ROOT=/usr/local/share/FlightGear
FG_HOME=/home/foo/.fgfs
... assuming that VERSION in config.h is "2.0pre-20080314". Which it isn't.
Instead it's "1.0.0" since yesterday, and was "0.9.10" before that. This
has yet to be discussed, and I'll add the option to options.xml later.
Reindent to Stroustrup style.
Make FGPrecipitationMgr an SGSubsystem and remove all references to it
in main.cxx and renderer.cxx.
Use SGGeod::makeZUpFrame instead of a private function in
tileentry.cxx. Rewrite that function, WorldCoordinate, to use
makeZUpFrame too.
Makes it possible to start at a parking location defined in the AI/Airports/*/parking.xml files, using the parkpos command line option.
Note that the name to pass is the concatenation of the "name" and "number" fields in the xml.
This allows Nasal managed views thanks to the proximity of the
event manager (which executes Nasal loops). The io manager must
come after the view manager to avoid jitter in network replay.
This also fixes distortion weirdness in the osgviewer version. That
was caused by osg::GraphicsContext getting in the act on resize events
and adding its own scaling to the projectionOffset of slave cameras!
The LOD far range on the tile entry scenegraph node was initialized to
0. This meant that any traverals of active children that happened
before the tile manager updated the node would ignore the node
altogether. Among these is the groundcache traversal which was failing
at startup even though scenery was loaded.
Also added a function to dump scene graph nodes to files; very handy
in gdb.
Make an OSG file reader for .stg files.
New class flightgear::SceneryPager, which is a subclass
osg::DatabasePager to handle explicit delete requests.
Modify FGNewCache, FGTileEntry, and FGTileManager to use
SceneryPager. Mostly this involved removing the queues that talked to
FGTileLoader.
Calculate accurate tile timestamps from the time they are traversed in
the cull stage (which means that they are visible) instead of updating
them periodically.
Replace tile entry transform and range node with one LOD node
are not available out-of-the-box on all systems and keyboards, and should
therefore not be used in files committed to CVS. This makes them well
suited for local key bindings, as they aren't likely to get overwritten
with later releases. SDL supports Meta and Super, OSG supports only Meta,
and GLUT supports neither.

This uses the osgViewer infrastructure instead of setting up and osg::SceneView.
When the same change is made for glut, much of render.cxx can be deleted.
file. Possible uses of this functionality could include converting the
model to some other format or coordinate system for use in some other
visualization or simulation.
This is required to make sure the same letter key gets released,
which got the press event. (After Ctrl-press -> a-press -> Ctrl-release
a-release we want the Ctrl-a binding released, not the a binding.)
- add key listener interface for direct key access from Nasal space
This removes some jitter in cases where Nasal is used to set up view
parameters from FDM data, such as position and orientation. (The event
subsystem handles Nasal's settimer() calls.)
This was correct in the old repository and in revision 1.1 of the new,
but then broken in revision 1.2. After that, "lookat" and "lookfrom"
mode used different coordinate systems, and the "Adjust View Distance"
didn't work correctly in "lookat" mode.
"I have been investigating the Concorde IVSI problem. I came to the
conclusion that the trouble is that the environment altitude and thus
the pressure (which is calculated from that) is lagging by 1 frame.
Normally that wouldn't be a problem, but the IVSI calculates rate of
change and it will use the new dt with the old value difference,
thereby arriving at bad results if dt changes (and it does)."

them under /sim/presets/ but they aren't save there, and as fgInitPosition

Turn OPENSCENEGRAPH_MAJOR_VERSION, OPENSCENEGRAPH_MINOR_VERSION and
OPENSCENEGRAPH_PATCH_VERSION into a single number for comparisons in the

This fixes a bug that caused both the x and y values of the mouse to
be reset when the cursor was recentered due to hitting the screen
edge.
Based on a suggested patch from Stuart Buchanan
On most Unix platforms like FreeBSD, Solaris, IRIX (AIX is even worse)
- just not on Linux - the linker wants to know about _all_ required
libraries. So even if a shared library "libosgViewer" itself is linked
against "libosgGA" and "libosgText", you still have to name these in
order to build an "fgfs" binary.
Currently, other libraries like "-losgDB" and "-losgUtil" are
explicitly mentioned on the "fgfs" linker command, but "-losgGA" and
"-losgText" are not. This simple patch lets the linker honour
everything that's required
"This patch fixes the use of the keypad with numlock in the osgViewer
version of FlightGear."
"This also restores the handling of resize events while trying to stay
out of the way of the multiple display code."
where type is one of string (default), double, float, long, int, bool
Using only the first letter works, too.
--prop:foo=123 ... sets property foo to string 123 (old behavior)
--prop:string:foo=123 ... verbose version of above
--prop:s:foo=123 ... slightly less verbose version of above
--prop:bool:foo=1 ... makes property a bool of value 'true'
I hope this isn't considered a silly gimmick. I need this often and maybe
other developers do, too. It's useful in cases where the difference really
matters. if (getprop("/foo")), for instance, is TRUE even when the property
contains string "false", as all strings are TRUE.
/sim/screneryloaded-override was "true". At least one subsystem (od_gauge)
waits for /sim/sceneryloaded to bypass CPU intensive code until the scenery
is up. This broke e.g. the RTT-radar when using /sim/screneryloaded-override
--prop:sim/sceneryloaded-override=true has the effect that fgfs
doesn't show the splash screen until the scenery is loaded, but shows
the OTW view (scenery/aircraft) at the earliest possible moment. This is
useful for developers who often need to run fgfs only to check some minor
detail, while not caring about stuttering caused by scenery loading.
simple SG_LOG instead. The user didn't call the fgcommand, so why should
s/he be bothered with that? And the actually caller of the command gets a
return value and can pop up a dialog if it thinks it's necessary.
Why /sim/fg-current at all? Because we have a file selector dialog
(still unfinished), and one might like to start it from the current
directory, to find saved flights/screenshots/whatever.
FGManipulator.*:
"This patch works around a bug in OSG's handling of modifier keys. The

fg_os_osgviewer.cxx:
"This patch fixes the test for support of cursor changes in OSG 2.0."
because this allows to load from FG_HOME. To reduce security risks, always
append an ".xml" extension if there was none. Makes it hard to read /etc/secret

throwing an instance of 'sg_io_exception'\nAbandon". And this is caused
by compiling fgfs/sg without exception support (unlikely) or linking
against a libSDL/libglut that was compiled/linked without execption
support. While we can't fix that, we can tell the users who's to blame. :-)
- handle const char * exceptions
- props is easy to mix up with the --prop option (for setting properties)
- the name is unspecific and inconsistent: other option names describe
the protocol -- the way to get the properties. How is, for example,
--httpd less about prop(ertie)s?
- two identical options easily confuse people, as can be seen in The
FlightGear Manual, where --telnet and --props were described differently
/sim/view[*] that it finds. It's not only unnecessary that view definitions
have subsequent indices, but aircraft are now *requested* to use indices
100++. /sim/view[0] .. /sim/view[99] are reserved for the system. (Not
that we'd ever need that many, This is just a convention, it's nowhere
hard-coded.)
- replace the string operations for property paths by method calls & other
improvements
because nasal's f_interpolate() may be called in Nasal at times when the
GENERAL subsystem group is being deconstructed; access it by addressing
the group directly, as using globals->get_subsystem() does then not
work any more then; yeah, it's all for a rare border case ... :-)
NasalSys.cxx more robust instead. The reason for the crash was that during
fgfs shutdown destroyed subsystems (GENERAL group) still need Nasal access
(for AI Model destruction listeners), but at that point globals->get_subsystem()
can't even deliver the "nasal" subsystem (INIT group). One way to solve that
problem would have been to replace globals->get_subsystem("nasal") by
globals->get_subsystem_mgr()->get_group(SGSubsystemMgr::INIT)->get_subsystem("nasal"),
but Andy decided to store a pointer to the active "nasal" subsysten in
NasalSys.cxx instead, as the "nasal" subsystem needs to be accessed in
every single Nasal extension function, and multiple "nasal" subsystems are
out of the question, anyway.
we need to explicitly destroy that here, too, so that it has guaranteed
access to the Nasal subsystem. Otherwise we get a segfault on exit. When
the next subsystem needs this special treatement (radar?), we should
introduce a new subsystem group (in addition to INIT and GENERAL)
"FATAL: PUI: No Live Interface! Forgot to call puInit ?"
We shouldn't use the splash progress message before guiInit().
Leave the "idle_state" step for now, to keep the similarity
with fg/plib as big as possible. This can be dropped later.
Patch to enable atc chatter (and any other arbitrary "message" audio file)

played at a hardcoded volume of 1.0)
- loop up file name in the cache at startup. If it's found, check if the
file exists and use it, otherwise scan $FG_ROOT/Aircraft/ as usual,
and create a new cache while doing that. Rebuild cache on FG_ROOT change.

Generally you want point sprites for performance reasons when enhanced runway
lighting (and smooth points) are activated. Most hardware doesn't
accelerate the rendering of standard smooth points, so without point sprites
you will kill your night time performance if you turn on enhanced runway
lighting.
Note that enhanced runway lighting "breaks" our clever scheme to make the
runway lighting brightness vary with the relative view angle. This means
with enhanced lighting on, all lights are equally bright no matter what
direction you view them from. So perpendicular runways are just as bright
as runways you are directly lined up with (when enhanced runway lighthing
is activated.)
You can revert to the original lighting scheme by turning off enhance runway
lights, turning off distance-attenuation, and turning off point-sprites in
the rendering options menu.
