fgLoad3DModel() throws an exception if it fails to load the requested model.
This causes FGTileMgr::update(...) to exit.  So I've added a try/catch block

ab49022465 Patch to position 3d clouds at center of <current> tile. This means the clouds
jump whenever you cross a tile, but there are currently a lot of other
positioning problems as well, so this doesn't really detract too much and
means you can play with 3d clouds from just about any starting point.

7599f0ec8c Patch from Julian Foad:
When the scroll bar slider is dragged, the list scrolls only far
enough to see all items; only the arrow buttons can scroll it so far
that the last item goes to the top of the view.
     Fix scroll bar proportional size: was wrong when the list was only
a little longer than the visible area.
     Minor fixes such as "delete files[i];" -> "delete[] files[i];"
(where the item being deleted is an array of characters) and removal of
global variables.
     Smooth scrolling when dragging the slider: one item at a time,
rather than one tenth of the list at a time.
     Fix a bug that would have occurred if instantiated with arrows=2.
     Sort properties primarily by name and then by numerical index
order, rather than a simple ASCII string order.  E.g. "js[1]", "js[2]",
"js[10]" rather than "js[1]", "js[10]", "js[2]".
     Avoid crashing if the selected property path does not exist;
display an empty list instead.  This cannot happen when the property
picker is working properly, but did happen due to missing indices prior
to this patch, and could happen if the user is allowed to type a
pathname, as in the http and telnet interfaces.
     Fix truncation of strings to PUSTRING_MAX: was wrong when string
length was exactly 80.
     Fix: move the scroll bar to the top each time a new list is
displayed.  It was left at its previous position, while the top of the
new list was displayed, not corresponding to the slider.
     Use getDisplayName instead of duplicated code: gives a better
decision on whether to display the index, and avoids invalid property
paths being generated which would previously crash find_props().
     Replace unnecessary node lookups by name with direct access: tidier
and more efficient.  E.g. "getValueTypeString
(node->getNode(name.c_str()))" -> "getValueTypeString (child)".

ee35eecb54 Erik Hofman:
I removed some pending random code and I also fixed a
small cosmetic glitch where dt_play was cleared before it was printed.

Curt: Erik changed the sound update intervale and I further I tweaked it.
The issue is that if we put too much into the sound buffer, then we can't react
quick enough to sounds like tire squeek that need to be synced with the visuals
and the action.  We put too little into the sound buffer and we risk the
audio dropping out for moment if a frame takes longer to draw than the amount
of audio in the buffer.

df6989a37a Bernie Bright:
Here is a FGIO class derived from FGSubsystem that replaces the fgIOInit()
and fgIOProcess() functions.  The FGIO::update(double delta) doesn't use the
delta argument yet.  I suspect it could be used as a replacement for the
calculated interval value but I'm not familiar enough with that piece of code
just yet.

I've also added two "command properties" to fg_commands.cxx that select the
next or previous view.  Writing any value to these properties triggers the
corresponding action.  As an example I modified my keyboard.xml:

 <key n="118">
  <name>v</name>
  <desc>Next view</desc>
  <binding>
   <command>property-assign</command>
   <property>/command/view/next</property>
   <value type="bool">true</value>
  </binding>
 </key>

 <key n="86">
  <name>V</name>
  <desc>Prev view</desc>
  <binding>
   <command>property-assign</command>
   <property>/command/view/prev</property>
   <value type="bool">true</value>
  </binding>
 </key>

And of course these actions can also be triggered from external scripts via
the props server.

4f00d9a959 Tidy up the autoconf/automake configuration a bit.
- Removed some old cruft.

- Removed some support for older versions of automake which technically was
  correct, but caused the newer automakes to squawk warnings during an
  initial sanity check (which isn't done very intelligently.)

  NOTE: this fix is technically not correct for older version of automake.
  These older version use the variable "INCLUDES" internally and could have
  them already set to an important value.  That is why we were appending
  our values to them.  However, newer versions of automake don't set this
  value themselves so it is an error to append to a non-existant variable.
  We seem to "get away" with overwriting the value on older versions of
  automake, but if you have problems, consider upgrading to at least
  automake-1.5.

1b197dd8bf Bernie Bright:
Here are some changes that gave me a significant frame rate increase of about 10 fps with random objects disabled.  The interesting thing is that these changes aren't in the main loop but are in tile loader.  My guess is that I've reduced the memory footprint just enough to reduce CPU cache misses, though I have no hard evidence of this.

Initially I modified all SGBinObject member functions to pass/return by reference instead of by-value.  This gives little or no speed up but allows for some optimizations in fgBinObjLoad().  It is these changes that reduce the number of memory allocations.  Needless copying of vectors, and vectors of vectors, can be very memory intensive, especially if they are large.

Anyway I would be interested to see if you get similar results.  I would emphasize that the frame rate increase only occurs with random objects disabled.  I lose about 10-15 fps on my GF2MX 32MB with random objects, probably a fill-rate limitation or texture memory thing.

0ebe8ec8f0 Removed the FG3DModel class and replaced it with fgLoad3DModel.
Animations are now contained within the scene graph itself and are
updated whenever the graph is traversed -- that saves time by not
updating animations not currently in sight, and it allows animations
to be used for static objects and random objects as well.

Added new FGModelLoader and FGTextureLoader classes.  These are intern
tables for models, to guarantee (mostly) that no model is loaded more
than once.  FGTextureLoader is not yet used anywhere, but
FGModelLoader is now in place everywhere that ssgLoad* used to be
used (thus adding the ability to use animations).

In the future, FGModelLoader will add some interesting functionality,
including the ability to reload 3D models on the fly.

    Fix truncation of strings to PUSTRING_MAX: was wrong when string length was exactly 80.
    Fix: move the scroll bar to the top each time a new list is displayed.  It was left at its previous position, while the top of the new list was displayed, not corresponding to the slider.
    Use getDisplayName instead of duplicated code: gives a better decision on whether to display the index, and avoids invalid property paths being generated which would previously crash find_props().
    Replace unnecessary node lookups by name with direct access: tidier and more efficient.  E.g. "getValueTypeString (node->getNode(name.c_str()))" -> "getValueTypeString (child)".

27158525a9 Restructure the way tile freeing is handled. When a tile is removed from
the tile cache it's ssg elements are disconnected from the main ssg scene
graph, and then the tile is thrown on the end of a delete queue.  The
tilemgr->update() routine runs every frame.  It looks at this queue and if
it is non-empty, it incrementally frees the compents of the first tile
on the queue.  When the tile is completely free it is removed from the queue.

The amount of time to free the memory for even a single tile can be quite
substantial, especially with the increased overhead of dynamic/random
ground objects.  This change allows the system to spread the work of freeing
tile memory out over many frames so you don't get a noticable single frame
hit or stutter.

29268401b2 Randomly-place object overhaul and enhancements
-----------------------------------------------

Fixed a segfault on exit.

Changed the radius of the dummy bounding sphere from 10m to 1000m to
ensure that FOV culling doesn't leave anything out.

Allow an object to have more than one variant model, which will be
chosen randomly.  Simply repeat the <path>...</path> property.

Removed the <billboard> property and replaced it with <heading-type>,
which can be set to "fixed" (leave the model oriented as it is),
"random" (give the model a random heading between 0 and 359 deg), or
"billboard" (always turn the model to face the camera).  The default
is "fixed".  Models look much better when they are not all facing the
same direction.

Allow the user to group models with the same visual range, so that
there can be *many* fewer nodes in the scene graph when the models are
not visible.  This causes an XML-format change, so that instead of

  <object>
   <range-m>...</range-m>
   ...
  </object>
  <object>
   <range-m>...</range-m>
   ...
  </object>
  ...

we now have

  <object-group>
   <range-m>...</range-m>
   <object>
    ...
   </object>
   <object>
    ...
   </object>
   ...
  </object-group>

Every object in a group can still have its own model(s), coverage, and
heading-type, but they all share the same range selector.

This change should already help users with tight memory constraints,
but it will matter much more when we add more object types -- for
example, we can now add dozens of different urban building types
without bloating the scene graph or slowing down the LOD tests for
tris that are out of range (i.e. most of them).

f7a17c9020 Modifed random-object code for more memory efficiency:
1. Only one copy of each object (and its texture) is stored in memory,
   no matter how many materials use it.

2. Random objects are added to a triangle only when the objects are in
   range, and they are deleted as soon as the objects are out of
   range.  That way, only a relatively small number of ssg nodes are
   used at any one time.

This patch seems to eliminate freezes when tiles are freed.  There are
occasional stutters at extremely high speeds (i.e. over 3,000kt), but
it seems smooth enough for normal aviation speeds.

This patch eliminates about 10 of valgrind's "Use of uninitialised

incomplete FGApproach class instances and then copying them into the
approchlist container, hence copying data garbage.
   I know, I couldn't win a beauty contest with this patch, but the
alternative approach -- letting operator<< always leave complete
entries -- didn't look any better. And I do only add those seemingly
useless initialization where the values would be used uninitialized
else. The constructors are only run during setup and won't slow fgfs
down at runtime.

b53cd9c59f 3D panel support from Andy Ross:
+ The panel(s) are now an first-class SSG node inside the aircraft
  scene graph.  There's a little code added to model.cxx to handle the
  parsing, but most of the changes are inside the new FGPanelNode
  class (Model/panelnode.[ch]xx).

+ The old FGPanel source changed a lot, but mostly cosmetically.  The
  virtual-cockpit code moved out into FGPanelNode, and the core
  rendering has been abstracted into a draw() method that doesn't try
  to set any OpenGL state.  I also replaced the old inter-layer offset
  code with glPolygonOffset, as calculating the right Z values is hard
  across the funky modelview matrix I need to use.  The older virtual
  panel code got away with it by disabling depth test, thus the "panel
  draws on top of yoke" bug.  PolygonOffset is really the appropriate
  solution for this sort of task anyway.

+ The /sim/virtual-cockpit property is no more.  The 2D panels are
  still specified in the -set.xml file, but 3D panels are part of the
  model file.

+ You can have as many 3D panels as you like.


Problems:

+ The mouse support isn't ready yet, so the 3D panels still aren't
  interactive.  Soon to come.

+ Being part of the same scene graph as the model, the 3D panels now
  "jitter" in exactly the same way.  While this makes the jitter of
  the attitude gyro less noticeable, it's still *very* noticeable and
  annoying.  I looked hard for this, and am at this point convinced
  that the problem is with the two orientation computations.  We have
  one in FGLocation that is used by the model code, and one in
  FGViewer that is used at the top of the scene graph.  My suspicion
  is that they don't agree exactly, so the final orientation matrix is
  the right answer plus the difference.  I did rule out the FDMs
  though.  None of them show more than about 0.0001 degree of
  orientation change between frames for a stopped aircraft.  That's
  within an order of magnitude of what you'd expect for the
  orientation change due to the rotation of the earth (which we don't
  model -- I cite it only as evidence of how small this is); far, far
  less than one pixel on the screen.

[and later]

OK, this is fixed by the attached panel.cxx file.  What's happened is
that the winding order for the text layer's polygons is wrong, so I
reverse it before drawing.  That's largely a hatchet job to make
things work for now, though.  We should figure out why the winding
order is wrong for only text layers and fix it.  I checked the plib
sources -- they're definitely doing things CCW, as is all the rest of
the panel code.

Odd.  I'm also not sure why the 2D panel doesn't care (it works in
both winding orders).  But this will allow you to check in working
code, anyway.  There's a big comment to this effect in there.

9541e06a1e Finally fixed the flap drag issue. Drag modifications need to be based on
the amount of drag that the produced lift *would* have produced given an
unflapped air surface.  A nifty trick involving the assumption that AoA is
small works for this, and produces plausible results in the high AoA case
as well.

Also, trim for approach using the elevator-trim control, not elevator.
Just cosmetic for current planes, but future ones might have differing
implementations of trim.

This is a small patch that makes the autopilot work much better with big heavy

way autopilots should be modeled.

But by making a couple changes the "George" is now capable of landing either a
C172 or a 747 very close to the center line of the runway with a moderate
cross breeze (15-20kt).

The changes:
- Added turn configurability so that things like Max Aileron and Roll can be
configured per aircraft.
- Enhanced localizer routine (NAV mode) to begin lining up the aircraft as soon
as the cone is entered.  The former model is adopted for the last 5km of the
approach in order to ensure greater precision (makes a very slight difference).

When solving for zero force, do so in the global frame, not the

frames), but in practice this should help to avoid oscillations.
Calculating lift as force perpendicular to the ground (and not the
wing plane) is clearly the Right Thing, anyway.

8ae364a220 Jim Wilson:
This is a small fix for what turned out to be a major bug.  Ground elevation
was calculated incorrectly when distant from one of the view locations. This
resulted in several problems including bizarre gear trimming, mid air
"crashes" (as in thinking we hit the ground) and so on when close to or on the
ground.

Unfortunately it does require a second ssg traversal when in tower view
(only), but the increased load isn't all that noticable.  For the time being
this really is the best solution.  In a future update I will be eliminating
the unecessary per frame traversals for the static views (without having to
maintain multiple ssgRoots).

When we go to multiple FDM instances we will perhaps need to put the ssg
traversal and ground elevation queries for the FDMs into an event timer that
updates the FDMs ground elevation in a round robin fashion (maybe every 1/n
seconds where n is the number of FDM instances running).

b1674cb506 From: "Jim Wilson" <jimw@kelcomaine.com>
This is a new improved patch for the previous tile manager fixes.

Rather than building dependencies between FGlocation or the viewer or fdm with
tilemgr what I ended up doing was linking the pieces together in the Mainloop
in main.cxx.  You'll see what I mean...it's been commented fairly well.  More
than likely we should move that chunk somewhere...just not sure where yet.

The changes seem clean now. As I get more ideas there could be some further
improvement in organizing the update in tilemgr.  You'll note that I left an
override in there for the tilemgr::update() function to preserve earlier
functionality if someone needs it (e.g. usage independent of an fdm or
viewer), not to mention there are a few places in flightgear that call it
directly that have not been changed to the new interface (and may not need to be).

The code has been optimized to avoid duplicate traversals and seems to run
generally quite well.  Note that there can be a short delay reloading tiles
that have been dropped from static views.  We could call the tile scheduler on
a view switch, but it's not a big deal and at the moment I'd like to get this
in so people can try it and comment on it as it is.

Everything has been resycned with CVS tonight and I've included the
description submitted earlier (below).

Best,

Jim

Changes synced with CVS approx 20:30EDT 2002-05-09 (after this evenings updates).

http://www.spiderbark.com/fgfs/viewer-update-20020516.tar.gz
 or
http://www.spiderbark.com/fgfs/viewer-update-20020516.diffs.gz

Description:
In a nutshell, these patches begin to take what was one value for ground
elevation and calculate ground elevation values seperately for the FDM and the
viewer (eye position).  Several outstanding view related bugs have been fixed.

With the introduction of the new viewer code a lot of that Flight Gear code
broke related to use of a global variable called "scenery.cur_elev".

Therefore the ground_elevation and other associated items (like the current
tile bucket) is maintained per FDM instance and per View.  Each of these has a
"point" or location that can be identified.  See changes to FGLocation class
and main.cxx.

Most of the problems related to the new viewer in terms of sky, ground and
runway lights, and tower views are fixed.

There are four minor problems remaining.  1) The sun/moon spins when you pan
the "lookat" tower view only (view #3).  2) Under stress (esp. magic carpet
full speed with max visibility), there is a memory leak in the tile caching
that was not introduced with these changes.  3) I have not tested these
changes or made corrections to the ADA or External FDM interfaces.  4) The
change view function doesn't call the time/light update (not a problem unless
a tower is very far away).

Details:
FDM/flight.cxx, flight.hxx - FGInterface ties to FGAircraftModel so that it's
 location data can be accessed for runway (ground elevation under aircraft)
 elevation.

FDM/larsim.cxx, larcsim.hxx - gets runway elevation from FGInterface now.
Commented out function that is causing a namespace conflict, hasn't been
called with recent code anyway.

FDM/JSBSim/JSBSim.cxx, YASim/YASim.cxx - gets runway elevation from
FGInterface now.

Scenery/newcache.cxx, newcache.hxx - changed caching scheme to time based
(oldest tiles discard).

Scenery/tileentry.cxx, tileentry.hxx - added place to record time, changed
rendering to reference viewer altitude in order to fix a problem with ground
and runway lights.

Scenery/tilemgr.cxx, tilemgr.hxx - Modified update() to accept values for
multiple locations.   Refresh function added in  order to periodically make
the tiles current for a non-moving view (like a tower).

Main/fg_init.cxx - register event for making tiles current in a non-moving
view (like a tower).

Main/location.hxx - added support for current ground elevation data.

Main/main.cxx - added second tilemgr call for fdm, fixed places where viewer
position data was required for correct sky rendering.

Main/options.cxx - fixed segfault reported by Curtis when using --view-offset
command line parameter.

Main/viewer.cxx, viewer.hxx - removed fudging of view position. Fixed numerous
bugs that were causing eye and target values to get mixed up.

4efbc97a4b Revert the recent changes to Atmosphere.cpp. They were actually in
the wrong place.  The Atmosphere::getStd*() calls are used by the
solver, and thus really need to return values for a "standard"
atmosphere.  Otherwise, an aircraft started up in Moscow will behave
differently than one initialized in Cairo. :)

The place where environmental pressure and temperature get inspected
at runtime is in YASim.cxx.  The changes there, happily, end up being
even smaller than the ones to Atmosphere.  This ends up replacing code
only, and removing some comments.

Here is the new super improved telnet property interface.  CVS changelog
is at the end of this message.  Once this new telnet code is in and
compiles every where we can remove Network/props.[ch]xx.  I've added a
--telnet=<port> command line option to invoke the new server.  Later on
we could remove the --props option, or least change it to invoke the new
server.  I'll let you decide.

I've added some new commands to the telnet interface:

view next      Select the next view.
view prev      Select the previous view.
view set <n>   Select view 'n'
view get       Return index of current view

I'm not sure if these same effects could be achieved through property
operations.  The commands provide a convenient shortcut in any case.

I'm also planning on adding a panel command to manipulate panels and
objects contained therein (eg simulated mouse clicks).  There is going
to be some commonality with the command objects so we may need to
rationalize this in the near future.

Finally, I've also included my python stuff.  This is still very much a
work in progress, basically I've been using it to test the new telnet
server.  I have  tested it with python 2.2.  Feel free to add it to the
repository if you want.  I would suggest a scripts/python directory

8a5cdbdbc6 Finished off the atmosphere model (Troposphere and lower
Stratosphere).  The atmospheric properties are as follow:

/environment/temperature-sea-level-degc
/environment/temperature-degc
/environment/pressure-sea-level-inhg
/environment/pressure-inhg
/environment/density-sea-level-slugft3
/environment/density-slugft3

Setting either the sea-level or altitude value automatically sets the
other value appropriate, except for temperature at altitude above the
Troposphere (where there's no reliable way to back-calculate it).  The
atmosphere model appears in the atmosphere_data array in
environment.cxx, and can easily be extended into the upper
stratosphere and beyond.

These are not yet tied into the FDMs or steam module.

5a849b66e8 Major overhaul:
- changed FGSubsystem::update(int) to
  FGSubsystem::update(delta_time_sec); the argument is now delta time
  in seconds rather than milliseconds

- added FGSubsystem::suspend(), FGSubsystem::suspend(bool),
  FGSubsystem::resume(), and FGSubsystem::is_suspended(), all with
  default implementations; is_suspended takes account of the master
  freeze as well as the subsystem's individual suspended state

- the FDMs now use the delta time argument the same as the rest of
  FlightGear; formerly, main.cxx made a special case and passed a
  multiloop argument

- FDMs now calculate multiloop internally instead of relying on
  main.cxx

There are probably some problems -- I've done basic testing with the
major FDMs and subsystems, but we'll probably need a few weeks to
sniff out bugs.

c37d2019e0 Patch from Melchior Franz:
- don't send "set" confirmation when in data mode. If an external
  program really cares if the settings were accepted, which is
  rather unlikely, it simply has to "get" the property again.
  The returned line would have been a pain to parse, anyway
  (something like "from-model =  'true'  (bool)").
- do not only "set" the first token, but concatenate all given
  tokens with a space in between. This won't be used much, but
  makes sense for setting strings, while it does no harm when setting
  numbers. Silently ignoring all but the first token is impolite. ;-)
- remove old, commented out debug message that doesn't make much
  sense any more.

1c513868b7 Erik Hofman:
I changed the sound code to let it use FGCondition. This changes the
code and configuration files rather drastically. Furthermore I've added
an in-transit mode which plays the sound only when the tied property is
changing.

Changes:

Code:
* Added condition support to trigger an event
* Removed the <type> section from the main event definition
   (this could be done using conditions)
* Removed the abillity to use several events with the same name,
   instead it is required to use conditions.
* Updated the README.xmlsound

Base package:
* Changed the configuration files accordingly.
* Changed flaps and gear to use the new in-stransit mode.
* Changed the flps.wav file so it can be looped.
* Created a new gear.wav file (whcih can be looped)
   and a gear-lck.wav file for gear locking sound.

IMPORTANT:
To change existing configuration files to the new ones, it is important
to pack events with the same name together into one singel event, using
the condition specification. Also, when using special types (inverted,
flip-flop, raise or fall) these should be changed to a conditions also.
For more information, please look at
FLightGear/docs-mini/README.xmlsound and the supplied aircraft
configuration files located under FlightGear/Aircraft (espesially
c172/c172-sound.xml and c310/c310-sound.xml).

cylindrical symmetry and should rotate only around the z-axis (i.e. a

3. Otherwise, set the lon/lat to the middle of the KSFO field.

don't distribute that scenery by default any more.

18e36a3302 UFO FDM patches from Jonathan Polley:
I have finished working the bugs out of my "Enhanced" version of the Magic
Carpet FDM.  The UFO FDM works the same as the Magic Carpet with the
following exceptions:

The aircraft's pitch is determined by the Elevator setting (with a pitch
rate of 45 degrees per second).
Climb is forward velocity * sin(pitch)
Speed is forward velocity * soc(pitch)

Roll is tied to the aileron (again, with a roll rate of 45 degrees per
second)
Turn rate is sin(roll) * 45 degrees.

Yes, this does mean that turning is quite a bit more sluggish than
climbing.

If you are wondering why a UFO FDM, it is because it's best that I not
replace the existing magic carpet and this FDM does behave like a UFO (it
hovers, can spin and pitch while hovering, and does not obey the laws of
physics ;)

586d767ab6 There was an integer overflow in the way elapsed_time_ms. Because the
SGTimeStamp "-" operator returns it's result in usec's, there is an upper bound of 37.8 minutes on the maximum difference this operator can reliably report
before the math overflows.  I change the global "int elapsed_time_ms" variable
to a "double sim_time_ms" and restructured how the value is calculated.
----
The practical result of the overflow bug is that a large negative dt was
passed to the event manager and the end effect was that no events would
be run until their counters caught up ... in another 37.8 minutes or so.

Synced to CVS 19:36 EDT 2002-04-10 (after this evenings JSMsim and Base

Description:
Added FGLocation class which is new home for calculating matrix rotations.
Viewer can now be configured to access rotations created by the model rather
than repeating the same calculations again.

Changed model initialization for the time being so that its location data is
available for the viewer (currently required by other subsystems).  At some
point we can move this back to fg_init along with the viewer initialization.

Seperated the update from the draw function in the model code.  The viewer
code needs the same matrix data, and moving the update portion at this time
does not increase the number of matrix math iterations.

Moved the model draw so that it always appears "in front" of lights and clouds.

Reogranized viewer update routine for using the FGLocation class and
simplified some more tasks.  The routine is fairly easy to follow now, with
the steps ordered and spelled out in comments.

Viewmgr only updates the current (visible) view now, with the exception of an
old reference to "chase view" that will be corrected in forthcoming changes.
Also will be doing some work on the viewmgr outputs.

Model is now clears the z-buffer in all modes.  This will be changed with the
next viewmgr update.  The only side effect is that models always disappear
when over 5km distant from the eye point (can't really see them anyway:-)).

Other than a flag to indicate "internal" view I don't anticipate the
configuration interface for viewmgr/views will be changed a lot for now.  It
is close to done.  The next viewmgr update will however rework the outputs so
may change location.

This code will run with the previous version of preferences.xml, but will run
faster with the newer version.  I am attaching a preferences.xml that should
not be commited before the code.  All the changes are in the /sim/view section
and should show a simpler view configuration that references model locations.
 Note that I've added a 2nd tower view in "lookfrom" mode for illustration
purposes. You can look around using the mouse.  You may want to remove that or
comment it out.

f1c03ed957 This patch includes the FGLocation class, a few fixes, cleanup in viewer code.
Synced to CVS 19:36 EDT 2002-04-10 (after this evenings JSMsim and Base
package updates).

Description:
Added FGLocation class which is new home for calculating matrix rotations.
Viewer can now be configured to access rotations created by the model rather
than repeating the same calculations again.

Changed model initialization for the time being so that its location data is
available for the viewer (currently required by other subsystems).  At some
point we can move this back to fg_init along with the viewer initialization.

Seperated the update from the draw function in the model code.  The viewer
code needs the same matrix data, and moving the update portion at this time
does not increase the number of matrix math iterations.

Moved the model draw so that it always appears "in front" of lights and clouds.

configuration interface for viewmgr/views will be changed a lot for now.  It
is close to done.  The next viewmgr update will however rework the outputs so
you can expect that the data that viewmgr is writing to the property tree
may change location.

a1294ea398 Viewer update from Jim Wilson:
Minor patches to initial tower view code.  Added calculation for "tower" at
any airport, placed a couple fractions of a degree off the center.  Moved the
farplane from 100m to 5km so that "lookfrom" mode can see the model.  5km is
still in a reasonable range for a depth buffer.  Note that looking at a model
anything but a small distance will cause some problems on older cards.
Temporarily changed viewer to always report elevation/lon/lat of the aircraft
in order to avoid a problem with the ground trim getting recalculated when
tower and aircraft are on different tiles.

Tower View and viewer config is in place.  Note that the interface is
still in a state of flux.  A couple of the config items (namely the
offsets) are still using the old settings.  The tower is hard coded
into the base package for a position off the starting runway at KSFO
and is probably not in the right place for there even.  Looks pretty
cool though!  Tower View is the third view.  If you aren't at KSFO
you'll just see blank space in view 3. It's looking through the earth or
something like that :-).  Important note: zoom in with a few
hits of the "x" key to see the plane better in tower view.

7543409e47 Attached are a fairly extensive series of patches to the ATC
system.  A chap from Germany called Alexander Kappes (cc'd) got
in touch with me a few weeks ago and has written the start of
Approach control.  At the moment tuning in to a valid approach
frequency (Dortmund or East Midlands) should result in vectors to
a spot about 3 miles from the active runway, and a telling off if you
stray too far from the correct course, in the console window.  He
seems to know what he's doing so expect this to improve rapidly!!

I've added a rudimentry AI manager and a hardwired Cessna at
KEMT on the runway - I'll remove it before the next release if I don't
have it flying by then.  There seems to be an issue with framerate
which drops alarmingly when looking at it - I've a feeling that I've
possibly created several Cessnas on top of each other, but am not
sure.

2717dba826 I have attached revisions to the UIUC code. The revisions include the
ability to run a nonlinear model with flaps.  The files ls_model.c and

this and/or when the changes make it to the CVS?  Thanks.

d372548782 Major restructuring: the Animation class is now an abstract interface,

Renamed the 'offset' property to 'offset-m' or 'offset-deg' as
appropriate; ditto for 'min' and 'max' properties.

50e25151e1 Patch from Melchior Franz:
My last patch fixed the initialization problem only for the main branch, but
ignored the _MWERKS_ branch.
- merged the branches, only the loop head needs different treatment;
- don't access n.type before it is initialized (valgrind complaint)
- created a constructor; the operator>> wouldn't have initialized all
  variables in case of a broken default.nav.gz entry, so we would have
  got a mixture of the broken one and the previous one; in case of
  the first entry, that would have made nice random values ... ;-)
- move the automatic FGNav variable into the loop, so that the gets
  cleanly constructed for every database entry.
- commented out the frequency min/max exploration, which isn't used at all
- updated the commented out debug output statements, which were simply
  copied over from the nav* files, but never adapted (I needed them :-)

  that, but there is no such comment in default.atis.gz, so the first
  data entry got thrown away
- commented out min/max frequency exploration (-> only for debugging)
- enhanced the constructor; the operator>> wouldn't have initialized all
  variables in case of a broken default.atis.gz entry, so we would have
  got a mixture of the broken one and the previous one;
- move the automatic FGATIS variable into the loop, so that it gets
  cleanly constructed for every database entry.
- don't access a.type before it is initialized
- updated the commented out debug output statements; they were still
  designed for the FGNav class ...

58e664a060 Patches from Jim Wilson:
This patch creates a seperate scene graph for the cockpit.  The near plane is
only moved up when in the interior (pilot) view.  This is because with
rounding (I presume) it the visible ground is a bit up higher than it is with
the older nearplane setting.  Not much, but it is enough to bury the wheels.
I suspected this might be true but spliting to two sg's confirms it.  If
necessary we can adjust the model up a bit when in interior view.  This might
be good so we can set the near plane even closer when in the cockpit (its
still at 0.2m).

In general this looks a lot better on my Voodoo with this patch.  No
perceptibel change in frame rate on my system.  In terms of future plans I'd
see the sense in making the model plug into either scene.  This will be
necessary when we have multiple model instances in the frame.

Think my brain is getting clogged with matrices :-).  Well I've got the funky
orientation offset bug out of the model code.  In the process the model.cxx
got optimized a bit.  At some point we'll need to liberate model.cxx from the
viewer class, but it is no longer hard coded to access the  "pilot view" to
get it's data. Instead it uses whatever the "current" view happens to be.  I
may try and do that final bit of having models rotate independant of the view
tomorrow night, or start right in on the viewmgr and get a tower view up and
running.  You guys have any preference?  My brother's family is coming to
visit for a few days so what I don't get done tomorrow night probably won't

5b2df63f54 Patches from Melchior Franz:
The first hunk might not be necessary, but the light_coverage property
was the only one that wasn't explicitly defaulted, which is unfair.  ;-)
   The second hunk adds the missing initialization to the init routine.
This is necessary, because (unlike the material entries from material.xml)
the generated light entries don't get the light coverage set. Yet
obj.cxx:795 reads this information out fot every leaf, although not needed
in the case of lights. Avoiding this isn't worth the trouble.
   The last hunk sets the missing normal_index. The POINTS branch in
gen_leaf was always called with this int_list empty, which made the normals
handling use data garbage.

b3d5d24d81 Patch from Melchior Franz:
It seems that the airport database was changed some day and the End?Flags
changed from floats to strings. The database definition, though, was not
adapted and still created number entries. Reading out these flags led to
access to memory, that was never initialized. While it didn't cause crashes
during normal use, it actually caused one when I ran fgfs in ddd. Seems,
that the concerned memory region wasn't zeroed out then and hence uncovered
the bug.

Of course, the runways.mk4 database has to be re-created with the new
definitions.

Viewer improvements from Jim Wilson:

These files get the 3d cockpit working and fix a few issues in the viewer
code.
XYZ offsets are now defined as follows: X -left/right+ (along wing axis), Y
-up/down+ perpendicular to the aircraft, Z is -in/out+ the aircraft's body axis.
I've also done some cleaning up of unused and mostly unusable interfaces,
added commentary to the *.hxx, combined together some duplicate code and
eliminated a couple unecessary operations.  I also moved what was left of the
"protected" zone to "private" since we aren't subclassing this anymore.

4d4cd16012 Major viewer-code overhaul from Jim Wilson:
Description:

This update includes the new viewer interface as proposed by David M. and
a first pass at cleaning up the viewer/view manager code by Jim W.

Note that I have dropped Main/viewer_lookat.?xx and Main/viewer_rph.?xx and
modified the Makefile.am accordingly.


Detail of work:

Overall:
The code reads a little easier.  There are still some unnecessary bits in
there and I'd like to supplement the comments in the viewer.hxx with a tiny
bit on each interface group and what the groupings mean (similar but briefer
than what you emailed me the other day).  I tried not to mess up the style,
but there is an occasional inconsistency.  In general I wouldn't call it done
(especially since there's no tower yet! :)), but I'd like to get this out
there so others can comment, and test.

In Viewer:
The interface as you suggested has been implemented.  Basically everything
seems to work as it did visually.  There is no difference that I can see in
performance, although some things might be a tiny bit faster.

I've merged the lookat and rph (pilot view) code into the recalc for the
viewer.  There is still some redundancy between the two, but a lot has been
removed.  In some cases I've taken some code that we'd likely want to inline
anyway and left it in there in duplicate.  You'll see that the code for both
looks a little cleaner.  I need to take a closer look at the rotations in
particular.  I've cleaned up a little there, but I suspect more can be done
to streamline this.

The external declaration to the Quat_mat in mouse.cxx has been removed.  IMHO
the quat doesn't serve any intrinsic purpose in mouse.cxx, but I'm not about
to rip it out.  It would seem that there more conventional ways to get
spherical data that are just as fast.  In any case all the viewer was pulling
from the quat matrix was the pitch value so I modified mouse.cxx to output to
our pitchOffset input and that works fine.

I've changed the native values to degrees from radians where appropriate.
This required a conversion from degrees to radians in a couple modules that
access the interface.  Perhaps we should add interface calls that do the
conversion,  e.g. a getHeadingOffset_rad() to go along with the
getHeadingOffset_deg().

On the view_offset (now headingOffset) thing there are two entry points
because of the ability to instantly switch views or to scroll to a new view
angle (by hitting the numeric keys for example).   This leaves an anomaly in
the interface which should be resolved by adding "goal" settings to the
interface, e.g. a setGoalHeadingOffset_deg(), setGoalPitchOffset_deg(), etc.

Other than these two issues, the next step here will be to look at some
further optimizations, and to write support code for a tower view.  That
should be fairly simple at this point.  I was considering creating a
"simulated tower view" or "pedestrian view" that defaulted to a position off
to the right of whereever the plane is at the moment you switch to the tower
view.  This could be a fall back when we don't have an actual tower location
at hand (as would be the case with rural airports).

ViewManager:
Basically all I did here was neaten things up by ripping out excess crap and
made it compatible as is with the new interface.

The result is that viewmanager is now ready to be developed.  The two
preexisting views are still hardcoded into the view manager.  The next step
would be to design configuration xml (eg /sim/view[x]/config/blahblah) that
could be used to set up as many views as we want.  If we want to take the easy
way out, we might want to insist that view[0] be a pilot-view and have
viewmanager check for that.

use

  node->getName() == "foo";

any more, and will have to use c_str() when setting a string value

efe559ead4 First baby steps towards restructuring the view architecture. I've
created a new class, FGViewPoint (declared in viewer.hxx) that holds a
single position in FlightGear coordinates, and have used it to factor
a lot of the common code out of viewer_lookat.cxx and viewer_rph.cxx.

I don't know whether this new class will stay or not; it might just be
a temporary step, or it might end up taking over much of the current
viewer functionality.  It would be a bad idea to code against it right
now.

bd3900a3ff Start of an internal 3-D view. If the property "/cockpit" (temporary
and soon to be renamed) is true, FlightGear will draw the 3-D model
even in internal view.  This makes sense right now only with the C310
model, since the others don't have any kind of interiors modeled and
all surfaces in all models are one-sided.

This isn't quite working yet -- the view code is very hard to
disentangle, and currently, if the view is not forward, roll and pitch
are applied incorrectly.  It looks interesting (modulo a messy model)
on the ground, in level flight, or looking straight ahead under any
other flight conditions.

d8b6786d20 This patch creates a sample manager next to the sound manager. The
difference between the two is this: A sample is file related and sound
is a authonomus entity. This means you can have several sounds pointing
to a single sample. In that case, just one sample is loaded into memory.
The advantage is you can play the same sample with different pitch or
volume, but with just one  sample loaded into memory.

To fully support this there is a new fucntion call:

    FGSimpleSound *sample = new FGSimpleSound("filename");
    mgr->add(sample, "name");

should be replaced by:

    FGSimpleSound *sample = mgr->add("name", "filename");

But the old behaviour is still supported with one minor change, sounds
with the same name aren't supported anymore.

f477a4603b Patch from Andy Ross:
Actually, I think I'm off the hook here; the problem is pre-existing.
What's happening is that the x/y offsets enter the modelview matrix at
line 346 in the current panel.cxx.  But note that the same
transformation also occurs before each instrument rendered at line
403.  What's happening is that the instruments are double-translated
relative to the background.

Unless I'm not understanding something, the one inside the instrument
render loop looks unnecessary.  Removing it fixes the issue and
doesn't cause any bugs that I can find.  It also fixes a bug where you
could scroll the instruments on top of the 3D panel, where the offsets
are supposed to be ignored. :)

Attached is a new panel.cxx which fixes that bug, and substantially
simplifies the virtual panel code (the matrix inversion that I thought
was needed wasn't, but there were some offsetting scale bugs that hid
the problem).

7e93fca8ee Virtual cockpit patches from Andy Ross:
What the attached patch does is map your panel definition onto a (non
z-buffered) quad in front of your face.  You can twist the view around
and see it move in the appropriate ways.

Apply the patch (let me know if folks need help with that step), and
then set the /sim/virtual-cockpit property to true.  You can do this
on the command line with --prop:/sim/virtual-cockpit=1, or via the
property picker.  Bind it to a key for fast toggling if you like.

The default bindings don't allow for "panning" the view, so you'll
have to modify yours.  These are the mappings to my joystick's hat
switch, for those who need hints:

   <axis n="6">
    <desc>View Direction</desc>
    <low>
     <repeatable>true</repeatable>
     <binding>
      <command>property-adjust</command>
      <property>/sim/view/goal-offset-deg</property>
      <step type="double">1.0</step>
     </binding>
    </low>
    <high>
     <repeatable>true</repeatable>
     <binding>
      <command>property-adjust</command>
      <property>/sim/view/goal-offset-deg</property>
      <step type="double">-1.0</step>
     </binding>
    </high>
   </axis>

   <axis n="7">
    <desc>View Elevation</desc>
    <low>
     <repeatable>true</repeatable>
     <binding>
      <command>property-adjust</command>
      <property>/sim/view/goal-tilt-deg</property>
      <step type="double">1.0</step>
     </binding>
    </low>
    <high>
     <repeatable>true</repeatable>
     <binding>
      <command>property-adjust</command>
      <property>/sim/view/goal-tilt-deg</property>
      <step type="double">-1.0</step>
     </binding>
    </high>
   </axis>

While the current implementation is happy with just plastering the
panel's notion of "screen" into the 3D world, this is actually more
general.  Each panel can, in principle, have it's own coordinate
system, and you could build a cockpit out of a bunch of them.  The
mapping is specified by providing a 3D coordinate for three corners of
the quad the panel should be mapped to; this should be pretty simple
to work with.

All that's needed for a perfectly general solution is a convention on
where to store the information (a cockpit xml file, or put it in the
aircraft -set file, or...), and some work on the panel's coordinate
system conventions (some of which don't coexist very nicely with a
generalized 3D environment).  Combine that with a plib model for the
non-panel interior of the cockpit, and we're golden.

I'm actually really pleased with this.  It worked better and more
quickly than I could have imagined, and impact on the surrounding code
is quite light -- a few property tests only.  But some stuff is still
missing:

+ No equivalent work was done to the HUD, so it still displays
   incorrect headings when the view changes.  The use of pixel
   coordinates deep in the HUD code is going to give me fits doing the
   port, I sure.  It's not nearly so well put together as the panel
   (where I just changed the setup code -- none of the rendering code
   changed at all).

+ I forgot that the panel was clickable. :)  Input events still have
   the screen coordinates, which essentially kills the interactivity
   when in virtual cockpit mode.  This won't be hard to fix; it's only
   broken because I forgot the feature existed.

And one note about the implementation choice: to get away from the
inevitable near clip plane issue, the virtual cockpit renderer simply
disables the z buffer.  This means that cockpits built using these
panels need to be z-sorted, which isn't too hard since they are static
geometry.  It also means that no two "virtual panels" can ever be
allowed to interpenetrate.  No biggie.

348ac42c90 Attached is a reasonably large patch to add a proper ATC
subsystem to Flightgear.  No more functionality is implemented
than at present (apart from an ATIS bug-fix - station wouldn't
change if the radio was switched directly from one station to
another) but it is much neater than the current hack and should be
easily extendable.

Some cruft is still probably left over in radiostack.[ch]xx such as
the bindings to the comm frequencies but I'll leave removing those
until I'm sure they're not needed there.

"shift" for sliding things around, and will figure something out for
blinking lights.

eaf9fa7621 Added FGEnvironmentMgr to provide information on the environment in
different locations, and hitched it into FGGlobals.  FGEnvironmentMgr
has taken over as the subsystem, while FGEnvironment is simple the
information that it returns.  I've removed current_environment
completely -- everything now uses properties or goes through
FGGlobals.  FGGlobals itself has a couple of useful methods:

  const FGEnvironment * get_environment ();
  const FGEnvironment * get_environment (double lat, double lon, double alt);

The first one returns the environment data for the plane's current
position, while the second returns the environment data for any
arbitrary location.  Currently, they both return the same information,
but that will change soon.
