e48967cb1d fix another crash on exit by finally converting the rest of unguarded
SGPropertyNode to guarded ones. This is also done for JSBSim/JSBSim.hxx,
for which JSB had given explicit permission a while ago. I postponed that

6ed0ece57c While I had the valgrind rig set up, I took the opportunity to plug a

d47eefb00c Fix an uninitialized data condition that crept in during the recent

solution time, so the ground plane was unset.  Valgrind was whining

97b75a79bf Inspired by a patch from Vivian, this adds a settable "WASTEGATE"
control to piston engines that allows external scripts to control the
turbo/supercharger boost programatically by setting this axis to
values in the range [0:1].  It also adds a "turbo-lag" attribute (a
time in seconds) to engines implementing turbocharger spooling delays.

This isn't terribly well tested, but doesn't seem to have broken
anything.

5fe860750e Mathias Frhlich:
This patch makes use of the vectors now available in simgear with that past
patch. And using that it simplyfies the carrier code somehow.

- Small additional factory's to the quaternion code are done in the simgear
  part. Also more explicit unit names in the factory functions.
- The flightgear part makes use of them and simplyfies some computations
  especially in the carrier code.
- The data part fixes the coordinate frames I used for the park positions in
  the carrier to match the usual ones. I believed that I had done so, but it
  was definitly different. Also there are more parking positions avaliable now.

d61bcae165 Vivian reported that the caster angle of the Hunter was experiencing
"jitter" when the aircraft was stopped.  This is a fundamental
characteristic of the gear model, and can't be fixed without major
surgery (and not a small amount of blinding insight).  But we can at
least clamp it so the value can't change unless the wheel is moving
with a nontrivial velocity (5cm/sec in this case).

029dda3297 In the process of changing, adding and removing files the last few years
there was the situation where four directories contained jst two files,
of which three directories were aircraft related, and one directory contained
test code from Curt that might be better of in SimGear anyhow.

This is just a patch to move a bunch of files to new locations. In case of
local changes to any of them you can do the following:

move replay.[ch]xx from src/Replay to src/Aircraft
move control.[ch]xx from src/Control to src/Aircraft
move ssgEntityArray.[ch]xx from src/Objects to simgear/screen

In addition it has been decided only to use .[ch]xx files in all directories
unless it's contained within an FDM specific directory, in which case the
author is free to do whatever (s)he wants.

In this repspect the following files have been renamed in src/Multiplayer:

tiny_xdr.[ch]pp has become tiny_xdr.[ch]xx
multiplaymgr.[ch]pp has become multiplaymgr.[ch]xx

76f4bc1cef Piston engine oil temperature model from David Luff:
Attached is a patch to add oil temperature to the YASim piston engine
model.  This brings to life one of the pa28-161's otherwise 'dead'
guages.  It's a pretty simple 'model' based on temperatures and warmup
times I've observed in the labs on auto engines and run through my
dodgy-memory filter.  It does the job of populating the guage with
something plausible though.

411d133a54 Mathias Frhlich:
I believe I have found the agl hud problems as well as the 'hole' in the
carrier's deck. I spent half the day to reproduce that problem, it did not
occure when you start on the carrier not does it occure with JSBSim and my
really often used testaircraft. So I really need to improove my helicopter
flying qualities.

I was under the impression that *all* FDM's call

FGInterface::updateGeo*Position(..)

so set the new position in the FDM interface. Therefore I had added at the
some code that updates the scenery elevation below the aircraft to *those*
functions.
Ok, not all FDM's do so :/

The attached patch factors out a function computing the scenery altitude at
the current FDM's position. This function is also used in those FDM's which
need to update this value themselves.
Also this patch restores the nearplane setting and uses the current views
altitude instead of the current aircrafts. I think that this should further
be changed to the eypoint's agl in the future.
The agl is again ok in YASim's hud.

b92f034550 Vivian Meazza:
Some quite extensive changes to the AIModel code:

1. Mathias has made major changes to the AICarrier code to provide better
alignment of an aircraft on deck with the carrier - this feature is a major
improvement on the existing, but has a bug which might cause it to fail when
the computer carries out other tasks - changing window size is a known
example. This bug is outwith this code.

2.  I have made significant changes to the AIShip code to enable a ship the
turn and roll smoothly.

3. I have added some simple AI which enables the carrier to remain within,
or return to, an operating box.

4. An automated turn into wind for flying operations.

5. A simplistic implementation of TACAN within AICarrier. I am in the course
of implementing this as a generic instrument, but this is some time off
completion.

7b824755ee Mathias Frhlich:
I have prepared a patch that:
- Introduces a FGTileMgr::scenery_available method which asks the tilemanager
  if scenery for a given range around a lat/lon pair is already loaded and make
  use of that method at some -9999 meter checks.
- Introduces a FGScenery::get_elevation_m method which queries the altitude at
  a given position. In constrast to the groundcache functions this is the best
  choice if you ask for one *single* altitude value. Make use of that thing in
  AI/ATC classes and for the current views ground level. At the current views
  part the groundcache is reused if possible.
- The computation of the 'current groundlevel' is no longer done on the
  tilemanagers update since the required functions are now better seperated.

Alltogether it eliminates somehow redundant terrain level computations which
are now superseeded by that more finegrained functions and the existence of
the groundcache. Additionally it introduces an api to commonly required
functions which was very complex to do prevously.

1869b30b58 Mathias Frhlich:
I have traced that reset on carrier problem down to several problems. One of
them is the fact that on reset the carrier is updated while the aircraft is
not. That made the aircraft drop down an elevator sometimes. Depending on the
passed realtime while loading some parts of the scenery.

4df7a3e9f8 Mathias Frhlich:
I have introduced the posibility to start directly on the carrier.

With that patch you will have a --carrrier=id argument where id can either be
the pennant number configured in the nimitz scenario or the carriers name
also configured in the carriers scenario.
Additionaly you can use --parkpos=id to select different positions on the
carrier. They are also configured in the scenario file.

That includes the switch of the whole FGInterface class to make use of the
groundcache.
That means that an aircraft no longer uses the current elevation value from
the scenery class. It rather has its own local cache of the aircrafts
environment which is setup in the common_init method of FGInterface and
updated either manually by calling
 FGInterface::get_groundlevel_m(lat, lon, alt_m);
or implicitly by calling the above method in the
 FGInterface::_updateGeo*Position(lat, lon, alt);
methods.
A call get_groundlevel_m rebuilds the groundcache if the request is outside
the range of the cache.

Note that for the real usage of the groundcache including the correct
information about the movement of objects and the velocity information, you
still need to set up the groundcache in the usual way like YASim and JSBSim
currently does.
If you use the native interface, you will get only static objects correctly.
But for FDM's only using one single ground level for a whole step this is IMO
sufficient.

The AIManager gets a way to return the location of a object which is placed
wrt an AI Object. At the moment it only honours AICarriers for that.
That method is a static one, which loads the scenario file for that reason and
throws it away afterwards. This looked like the aprioriate way, because the
AIManager is initialized much later in flightgears bootstrap, and I did not
find an easy way to reorder that for my needs. Since this additional load is
very small and does only happen if such a relative location is required, I
think that this is ok.

Note that moving on the carrier will only work correctly for JSBSim and YASim,
but you should now be able to start and move on every not itself moving
object with any FDM.

Is a followup of the scenery center update code: Register the scenery center
transform at the time it is put into the scene graph not at creation time.

4.
I held that part back from the past hitlist patch, because I hoped that it
will be sufficient (and the last one was in fact the biggest part) without.
As some test cases from Melchior showed me, it is not. We have additionally
to the wrong computed transform from the prevous patch some roundoff
problems. This patch adds some small tolerance to for the point in triangle
test.
... may be one even needs to increase the eps value further if starting at
some tile boundaries still fails.

5.
That is a big chunk.
Tested now for two days while hunting the second patch  :) .
That is a partial rewrite of the groundcache to use its own datastructures for
that flat scenegraph in the cache. The basic advantage is, what Erik
suggested, to precompute some often used values of these triangles. Also
allmost all computations are now in double precision which should decrease
(hopefully fix), together with a similar tolerance for some point in triangle
tests, the problems with 'no ground below aircraft'.
I am playing with octrees for the groundcache, that will finally solve the
performance problem when high triangular count models end up in the
groundcache. This patch is also some prework for those octrees ...

4c10ef139c Mathias:
I have done a patch to eliminate the jitter of 3D-objects near the viewpoint
(for example 3D cockpit objects).
The problem is the roundoff accuracy of the float values used in the
scenegraph together with the transforms of the eyepoint relative to the
scenery center.

The solution will be to move the scenery center near the view point.
This way floats relative accuracy is enough to show a stable picture.

To get that right I have introduced a transform node for the scenegraph which
is responsible for that shift and uses double values as long as possible.
The scenery subsystem now has a list of all those transforms required to place
objects in the world and will tell all those transforms that the scenery
center has changed when the set_scenery_center() of the scenery subsystem is
called.
The problem was not solvable by SGModelPlacement and SGLocation, since not all
objects, especially the scenery, are placed using these classes.

The first approach was to have the scenery center exactly at the eyepoint.
This works well for the cockpit.
But then the ground jitters a bit below the aircraft. With our default views
you can't see that, but that F-18 has a camera view below the left engine
intake with the nose gear and the ground in its field of view, here I could
see that.
Having the scenery center constant will still have this roundoff problems, but
like it is now too, the roundoff error here is exactly the same in each
frame, so you will not notice any jitter.

The real solution is now to keep the scenery center constant as long as it is
in a ball of 30m radius around the view point. If the scenery center is
outside this ball, just put it at the view point.

As a sideeffect of now beeing able to switch the scenery center in the whole
scenegraph with one function call, I was able to remove a one half of a
problem when switching views, where the scenery center was far off for one or
two frames past switching from one view to the next. Also included is a fix
to the other half of this problem, where the view position was not yet copied
into a view when it is switched (at least under glut). This was responsible
for the 'Error: ...' messages of the cloud subsystem when views were
switched.

I have some small updates to the ground cache.

- Remove the usage of dynamic_cast where it is known that the result will be
  non null.
- Renormalize the surface normal in double precision.
- Place the groundcaches center at the point it was requested not at the
  scenery center. This fixes the problems with JSBSim's trimming together with
  the ground cache. Now I am ready to commit JSBSim's ground cache usage.

86249209b9 This is a work in progress. I am extending the "ExternalPipe" protocol to
have a "property" mode as well as the original "binary" mode.  The property mode
will allow the remote module to request any set of properties, and it will send
those properties each frame.  The remote module can reply with a list of arbitrary
property name/value pairs to update on the FlightGear side.

This is a first stab, so it's not the cleanest, most well concieved code, but it
allows an external module (communicating via a pipe) to have a huge amount of
flexibility in the data in can access and update.

Stub in hooks for Propeller feathering controls and the turbo prop "condition"
lever.

I added a line in FGFDM.cpp to force control properties to exist if they
don't already.  This way you can specify anything you want and find them
in the property browser, otherwise no one else may create them and you are
stuck.

In PropEngine::solve() the code original sets _running = true at the
beginning and then sets running = false at the end.  I changed this to
save the current value at the start, set to true, solve(), and then
restore the original value at the end.  That way if we start off with
_running = true, we don't have to hack up the calc() routine which wasn't
using the value anyway.

Finally I added some very initial support to shut down a turbine engine
(_running = false) when the condition lever goes to zero.

7ceb85d454 Changes to get FlightGear (well, the src directory at least) to
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.
