under some circumstances. The history of this patch is somewhat unclear,
but was brought to my attention by Martin Spott, while preparing for the
Lelystad FSWeekend show. See also my posting on FlightGear devel, on
November 22, 2007 "(Multiplayer Local Echo Patch)", but wasn't committed
then because I/we assumed that had been superseded by other code
modifications. The local echo problem still persists, however, albeit
under specific circumstances. The current patch reportedly prevents this
from happening.
and the pushback code:
- Traffic manager starts modelload requests immediately upon program
loading
- Only create legs 1 (push back) or five (cruise) of AI traffic.
- AIAircraft's rather obsessive behavior to circle around a waypoint is
largely resolved
- More realistic ground steering for AI aircraft.
Thanks to Vivian Meazza for debugging this. The output deque for
FGDigitalFilter was not being kept long enough for the
doubleExponential filter. Reads from output[1] could cause a crash.
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
Introduce a convenience member function in wxRadarBg for creating an
SGPropertyNode and initializing it in one step. Use this in
agRadar. This eliminates buggy behavior when the necessary radar
properties aren't defined.
$ 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.
As discussed with Tim on irc: Here is a quick fix for the memory-hungry tile
manager. Due to bugs in FGNewCache, old tiles were never deleted.
I left the timestamp-updates in the cull-traversal. but imho things work
just as well when timestamps are updated in FGNewCache::insert_tile() and
FGNewCache::get_tile()
Lee has added two new filter types, "gain" and "reciprocal". These filters can
read their gain factor from a property. In the process we also added minimum
and maximum output clamps that are applicable to all filters.
I added the ability to configure adaptive controllers i.e. the controller gain
can be tied to a property, so that it can be changed at runtime. This
requires a change in the xml structure of the autopilot configuration file:
<Kp>
<prop>/autopilot/KAP140/settings/ROL/Kp</prop>
<value>0.10</value>
</Kp> <!-- proportional gain -->
The old method <Kp>0.10</Kp> still works so as to not break all existing
autopilots, but it will output a warning to use the new method.
Please find attatched a new version of xmlauto.cxx.
Remove the call to build() in reinit(). This prevents build() from being
called twice when Reload Autopilot is selected from the Debug menu.
I've also added the ability to define an enabled property for the filters.
It's used like the PID controllers. If there is no enabled tag then the
filter defaults to enabled so that nothing should get broken by this change.
This ability can be used to create a filter between the output of a PID
controller and the property that it controls (a control surface). By putting
a noise spike filter between the output of a controller and the control
surface that it controls, we can simulate the limited movement rate that is
inherent in autopilot servos.
This patch contains bugfixes from my previous patch
(i made mistakes when using "diff" utility last time):
1. Now ATC do not tells us to go around because of
traffic on RWy, when that traffic is WE.
2. Now ATC don't say that we must follow ourself
(like "GFS, number two, follow GFS on final").
And new Tower-ATC features:
1. Requesting departure clearance. When you are
on taxiway, you can request departure clearance.
Tower will answer with something like:
"Line up runway two eight right".
TODO: check if any AI-Planes on final and tell
something like: "After the landing AI-CALLSIGN
line up runway two eight right".
2. Requesting take-off clearance. If you are on
runway, you can tell to ATC that you are ready
for take-off. So, Tower will tell you that you
are cleared for take-off (or immediate take-off).
3. Reporting landing gear position on final by pilot.
If you are on aircraft, which landing gear can
be UP, when reporting final you will tell
"Gear down, ready to land".
4. Reporting landing gear position on final by ATC.
When i was newbie and was flying on Cessna 310, i
ALWAYS forgot landing gears on final. Now if you are on
final and forgot landing gear, Tower will tell you:
"LANDING GEAR APPEARS UP" or "Check wheels down and
locked". So you will have some time to push gear
down or execute missed approach ;)
5. ATIS phonetic ID in requesting landing message.
In FG pilots says: "for full stop with ATIS" everytime
(when airport doesn't have ATIS too). But in real life
pilot saying phonetic ID of ATIS message. Now we have:
"for full stop, information alpha ... / ... zulu".
If airport doesn't have ATIS, pilot don't say this.
TODO: add this feature to AI-Planes too.
6. Advising weather condition in airport by Tower.
If you are requesting take-off or landing in airport
that doesn't have ATIS service, Tower will tell you
about wind direction and speed, visibility and QFE.
7. Reporting downwind if missed approach. When some AI-Plane
is on final FG's ATC tell you to "continue approach".
And then you lost radio transmission. Now ATC says:
"continue approach and report left/right downwind".
And now we have "Report Downwind" entry (button)
in "ATC Communication" form.
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
This fixes a race condition when teleporting somewhere outside of the
currently loaded scenery. Before, if there was no valid scenery, an
aircraft might end up at the center of the earth...
Instead of just reporting that the magic number, length, etc. of a
multiplayer packet is invalid, abort processing this packet. Also,

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.
Some cleanup in tileentry.cxx, but mostly code to implement loading of tiles
and their models without reference to FGTileEntry or SGBucket structures.
Also, don't do deferred model loading; load them when the tile is loaded.
_material was uninitialized. This was causing a segfault with
as-yet-to-be-checked-in paging code; I don't know if it ever resulted
in a segfault with the old tile loader, but it certainly could have.
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)."

argument:
setlistener(<property>, <func> [, <initial=0> [, <persistent=1>]])
This definition defaults to the old behavior. The fourth argument can
be set to zero, in which case the function is only called when the
node value has actually changed. It should really default to zero, but
then all callers would have to be reviewed, which is a bit too dangerous

remove all those 41 hacks if possible. Metrowerks is under category

work on PowerPC (which we don't support, anway, right?) and on some
Unices. The hacks are in CVS since the first commit 2002/9/10 (old
repository!) and probably were in the code long before that. Any
platform where such a broken compiler is still used, will hardly
be suitable to run fgfs at all.

In the long run this linear search shall be replaced with a spatial
algorithm (like octree), which will be a much bigger performance gain.

the runway length/width/surface material, so that fgfs doesn't drop one on
the ridiculous grass stripe parallel to the grown up concrete runway
(LOWL, LOXZ, ...). The weighting factors are for now made configurable,
so that they are easier to adjust. This can later be made static.
(will soon get forward ported to fg/osg)
Usage: airportinfo("KSFO");
airportinfo(37, 122); # airport closest to lat/lon
airportinfo(); # airport closest to current position
Returns nil on error, or a data hash otherwise. Example:
# length of runway 28R
var len = airportinfo("KSFO").runways["10L"].length;
Note that only one side of a runway is returned.
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
Anders said:
With Stuart's help I've looked closer at this and I think I've tracked
down the cause of the problem:
At least on my computer the sort() call on line 234 in
Environment/environment_ctrl.cxx sorts the vector entries by memory
address instead of altitude, i.e. the custom comparison predicate is not
used. This causes the tables of environment conditions to be reordered
into a wrong order at some weather updates, depending, basically,
on where the memory allocator places the objects. (Btw. why are they are
freshly allocated for each update?)
and "isOnRunway".
- Added initial support for AI controlled pushback operations, making use of the
current editing capabilities of TaxiDraw CVS / New_GUI_CODE. The current
implementation is slightly more computationally intensive than strictly
required, due to the currently inability of taxidraw to link one specific
pushBack point to to a particular startup location. FlightGear now determines
this dynamically, and once we have that functionality in TaxiDraw, the
initialization part of createPushBack() can be further simplified.
- Smoother transition from pushback to taxi. No more skipping of waypoints, and
aircraft wait for two minutes at pushback point.
- The classes FGTaxiNode, FGTaxiSegment, and FGParking, now have copy
constructors, and assignment operators.
- Removed declaration of undefined constructor FGTaxiNode(double, double, int)
- Array boundry checks and cleanup.
- Modified Dijkstra path search algoritm to solve partial problems. Currently
limited to include pushback points and routes only, but can probably be
extended to a more general approach.
- Added initial support for giving certain routes in the network a penalty, in
order to discourage the use of certain routes over others.
"interpolates METAR changes over time as follows:
1) Wind changes are interpolated as vectors, so the change is much more
natural than before - no-longer will your aircraft be suddenly shoved to
one side.
2) Visibility is interpolated as an X-value, which looks pretty neat.
3) Cloud heights and thicknesses are interpolated if they are close to the
aircraft. Cloud textures are not."
- support optional <preamble> and <postamble> which are written right
after opening and before closing respectively. This can be used for a header
line or an XML header.
- unescape <preamble>, <postamble>, <format>, <line_separator>, <var_separator>
so that \t, \n, \r, \f, \v, \xnn, \nnn can be used directly (\a and \b are
ignored; use \\ for the backslash) The long names ("carriagereturn") are still
supported for <var_separator>, but one can just use \r, or \r\n too.
- don't abort when a chunk doesn't have a <node>. This is useful for adding
constant chunks which consist only of a <format>, such as XML tags.

- 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

I refactored the XML loading code out of FGAirportDynamics and
FGRunwayPreference. I also added a new class XMLLoader, which serves as a
facade to the loader functions. Further I changed FGRunwayPreference to just
keep a FGAirport ref, which is more concise and closer to the right(tm)
solution than storing the airport data a second time ;-)
