0bb1494452 David Luff:
Attached is a patch to the airport data storage that I would like committed
after review if acceptable.  Currently the storage of airports mapped by ID
is by locally created objects - about 12 Meg or so created on the stack if
I am not mistaken.  I've changed this to creating the airports on the heap,
and storing pointers to them - see FGAirportList.add(...) in
src/Airports/simple.cxx.  I believe that this is probably better practice,
and it's certainly cured some strange problems I was seeing when accessing
the airport data with some gps unit code.  Changes resulting from this have
cascaded through a few files which access the data - 11 files are modified
in all.  Melchior and Durk - you might want to test this and shout if there
are problems since the metar and traffic code are probably the biggest
users of the airport data.  I've also added a fuzzy search function that
returns the next matching airport code in ASCII sequence in order to
support gps units that have autocompletion of partially entered codes.

More generally, the simple airport class seems to have grown a lot with the
fairly recent addition of the parking, runway preference and schedule time
code.  It is no longer just an encapsulation of the global airport data
file, and has grown to 552 bytes in size when unpopulated (about 1/2 a K!).
 My personal opinion is that we should look to just store the basic data in
apt.dat for all global airports in a simple airport class, plus globally
needed data (metar available?), and then have the traffic, AI and ATC
subsystems create more advanced airports for themselves as needed in the
area of interest.  Once a significant number of airports worldwide have
ground networks and parking defined, it will be impractical and unnecessary
to store them all in memory.  That's just a thought for the future though.

7311d05c87 Oliver Schroeder:
I have prepared a new patch for multiplayer, which fixes endianess issues with
multiplayer code. It's basically identical to the patch I sent before my
vacation, but contains minor fixes.

Multiplayer should now be working under all unix-like environments and windows
native. The basic trick is to let configure check for endianess of the host
system.

It will not work on system not using configure in the build process (excluding
windows), ie. possibly MACOS. For those system we should provide #ifdefs in
tiny_xdr.hpp.


Erik:
I've updated the patch to use the Plib utils package for endian swapping an
used a preprocessor directive to detect endianess.

Roy Ovesen:

You are right. I would suggest resizing input[] to (samples + 1) instead.
Change lines 654 and 661 to:

input.resize(samples + 1, 0.0);

That way we average over the number of samples as configured.

There was a patch from Manuel Masing a few months ago which cleaned up

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 Fröhlich:
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.

- automatic detection of axis directionality, so that axis inputs are appropriately inverted only when necessary
- fixed trim axis names for better understandability
- fixed signs for flaps up/down property increments
- button 0 was previously used for skipping axes and buttons in both loops. Now button 0 can be assigned a binding (e.g., brakes). Instead, moving any axis during the button-assignment-loop indicates skipping.
- The user is now told how to skip a control.

83b414482f Harald JOHNSEN:
I did some profiling of the code and found a few interessant things. Some corrections are obvious like the one in the multiplayer code, the fps is no more divided by 2 or 3 when another plane is on screen.

Other things like collision detection and computation of agl can not really be optimized. I changed a few things in hitlist.cxx but this only give a very low increase of fps. The groundcache eats a lot of cpu but I think that the real way to do it is to use a real collision system like OPCODE or something like that.



And I added an option to disable the recording of replay data. It takes more cpu than we can think.


Changes
=======

- panel.cxx :
  moved the computation of the instruments diffuse color outside the texturelayer code
  since this is constant during a frame, this is a big speedup for 2D panels ;

- hitlist.cxx :
  changed the computation of the intersection between ray and triangle, optimized
  the sphere culling by using a normalized direction vector. This can give a
  35% speedup on the computation of elevation in some situations ;

- renderer.cxx, acmodel.cxx :
  call ssgDrawAndCull with plane scene graph in external or internal view,
  calling ssgDrawAndCull with the root scene graph was drawing other players plane
  a second time in multiplayer mode ;

- mplayer.cxx :
  removed the calls to ssgFlatten and ssgStripify because it was degenerating models,
  causing a massive drop in frame rate ;

- replay.cxx :
  added an option to disable the recording of the flight

- fgclouds.cxx :
  changed the path of cloudlayer properties to match preferences.xml ;
  set the altitude of clouds from scenarios to a more correct value if metar is not enabled ;

I have now included a patch to the multiplyer protocoll which does:

1. place the 3d model into the scenery using a placement transform which can
dynamically change its scenry center.
2. Transmits unique position and orientation data for the 3d model.
3. Thus breaks protocol compatibility.

Oliver Schroeder:
With help from Norman I fixed the alignment in the used headers.

But this patch again fixes only symtoms, not the problems. I suggest to
put it into cvs anyway, as it will enable the majority to get experience
with the multiplayer mode.

Changes
=======

- shadowvolume.cxx, renderer.cxx :
  - reduced the polygon offset a bit to eliminate some artifact ;
  - changed again the cleanup code for objects inside a tile because it could crash on rare occasion ;
  - the culling of shadow casters has been rewritten to traverse the scene graph, it should be
    a bit faster when there is a lot of objects ;
  - the range selector was not correctly handled, sometimes the wrong LOD was casting shadows.
  - added the option to display aircraft's transparent objects after the shadows, this will
    reduce the problem of shadows being hidden by the transparent object (propeller disk,
    rotor, etc). A side effect is that aircraft's transparent objects won't receive shadows
    anymore. This is usually a good thing except when the aircraft use a 'transparent'
    texture where it should not. A transparent texture in the plib context is a texture
    with an alpha channel or a material with alpha <= 0.99.

- model.cxx, animation.cxx, shadowvolume.cxx :
  - added an optional <condition> under the <noshadow> animation

- tower.cxx
  - correct a rare bug where all occurences of the aircraft are not deleted from the
  departure list causing a crash in FGTower::CheckDepartureList function.

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
