"the [...] patch (for fg) increases the time before invisible geometry (i.e.

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
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then because I/we assumed that had been superseded by other code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!
