ability to run a nonlinear model with flaps. The files ls_model.c and
uiuc_aero.c were changed since we had some functions with the same
name. The name changes doesn't affect the code, it just makes it a
little easier to read. There are changes in LaRCsim.cxx so UIUC
models have engine sound. Could you send me an email when you receive
this and/or when the changes make it to the CVS? Thanks.
Also I noticed you have some outdated files that are no longer used in
the UIUCModel directory. They are uiuc_initializemaps1.cpp,
uiuc_initializemaps2.cpp, uiuc_initializemaps3.cpp, and
uiuc_initializemaps4.cpp

and specific animation types are derived from it. This change makes
the code much easier to read, maintain, and extend.
Added a 'translate' animation type for a scaled, 3D linear translation
(such as a sliding throttle knob).
Renamed the 'offset' property to 'offset-m' or 'offset-deg' as
appropriate; ditto for 'min' and 'max' properties.
MSVC fix from Bernie Bright:
You can keep the enum private if you add the following declarations
immediately afterwards:
struct mouse;
friend struct mouse;
It seems that MSVC doesn't grant the nested mouse decl. any special
access privileges to its surrounding class.
Clear frame buffer and render model after rest of 3D scene. This has a
small frame rate cost (YMV). But who thought 3D cockpit would be cheap?
If anyone has a better idea, have at it!
Just did some more careful testing and I see little or no frame rate loss
with the depth buffer clear. Also you can change the near plane to 0.1
and get rid of the "sunroof" (so I don't have to make up another set of
patches.
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 :-)
* src/ATC/atislist.cxx
Patch from Melchior Franz:
- merged the _MWERKS_ & generic #ifdef branch, only the loop head needs
different treatment
- commented out a "n >> skipeol" that is used in navlist.cxx to gobble
the starting C++-style comment from default.nav.gz; atis inherited
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 ...
- merged the _MWERKS_ and the generic branch, only the loop head needs
different treatment
- created a constructor; the operator>> wouldn't have initialized all
variables in case of a broken default.fix.gz entry, so we would have
got a mixture of the broken one and the previous one; (valgrind
complained ...)
- move the automatic FGFix variable into the loop, so that the gets
cleanly constructed for every database entry.
- don't access fix.type before it is initialized
- updated the commented out debug output statements (they were copied
over from navlist.cxx but never adapted)
radiostack.cxx:703 says
bool light_on = ( outer_blink || middle_blink || inner_blink );
but none of the flags has ever been initialized when this line is first
executed.
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.
The matrix doesn't define some cells, which are actually used
in the multiplication. That makes the result unpredictable.
I have no idea if 0.0 is the correct value for these, but
garbage is hardly the correct value either. Should some of them
be set to 1.0?
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
get done until after the weekend.
The compiler complains about too long names for instanciated templates
that result in name truncation. There are warnings but finally it ends
with a fatal errors. I found that ignoring the warning cure the
problem.
as a follow-up of my previous message, I found that in panel.cxx, function
const char *FGTextLayer::Chunk::getValue () const, there is the use of a
member variable _buf that seems to be uninitialized.
When the loop starts, n.type is still undefined, so the while statement
depends on unitialized garbage. The input operator cares for the [End]
bracket anyway (returns if the first character is a '['). So it is safe
to check for it after reading the line and break if necessary.
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.
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.
Fix FGViewer::update so that pitch offset and goal pitch offset work
together nicely (the offset was snapping to 90/-90 when only one of
the two was changed).
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.
(mainly in src/Input/input.cxx) will make src/GUI/mouse.cxx obsolete
and bring the mouse into the same input system as the joystick and
keyboard. This is just preliminary work allowing, covering mouse
clicks (no motion yet), and it actually crashes on a middle or right
click.
The new mouse support is disabled by default until it become stable;
to try it out, you need to configure --with-new-mouse.
for fuselage Surface objects. If the fuselage wasn't aligned perpendicular
to the Y axis, the matrix wouldn't be orthonormal. Since all of, perhaps,
three aircraft have ever been built this way, it's doubtful I would have
found this as a bug report. :)
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.
interface instead of string. This will result in a lot more
efficiency later, once I add in a simple hash table for caching
lookups, since it will avoid creating a lot of temporary string
objects. The major considerations for users will be that they cannot
use
node->getName() == "foo";
any more, and will have to use c_str() when setting a string value
from a C++ string.
inclueded in some of the files. Irix doesn't have cout in the std class,
so I changed it to "cout" and included SG_USING_NAMESPACE(std) at the
beginning of the files.
And some minor warning cleanups.

Also, I (David Megginson) removed most of the SimGear include
statements from globals.hxx, reducing the amount of recompilation
every time SimGear changes. This required making minor changes to a
lot of files that were depending on the side-effects of the inclusions
in globals.hxx.

There should be no change in functionality.
is a work in progress and needs severe enhancement before it will be
useful. It provides a UDP data channel that goes both ways between
flightgear and the fdm. It also provides a TCP 'command' channel so
flightgear can 'reliably' send commands to the remote fdm (such as set
starting position, reset on ground, etc.)
includes the ability to specify per vertex normals rather than depending

previous binary file format scenery is maintained.)
This seems to pretty much correct the problem. Part of the problem is that
rotations are occuring at the firewall (model origin) which seems a little
un-natural inside the cockpit. The rest of the problem is I am just learning
how this stuff works (I know I've been saying this for a couple months
now...but hey I'm slow :-)).
* Add new trigger types: raise, fall
* Add new trigger offset parameter
* Add new volume/pitch types: inv, abs, sqrt
* Add initial support for multiple events to intervere in a single sound
(by using the same name, see the crank section of 172-sound.xml)
* Cached the volume/pitch type fucntions
(No more if's inside the loops in update())
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.
plane to 0.2; otherwise, use the old defaults.
This is a temporary step that will allow me to work on a 3D cockpit
without breaking current behaviour; the final approach will be to put
the 3D model in its own scene graph, with different clipping plane.
OK, attached is a replacement for mouse.cxx that works the view using
the view-offset/tilt interface, rather than the (kinda odd) GuiQuat
stuff. It's kind of a hack job, as I left the hooks to GuiQuat in in
other places for fear of breaking something. Still, it removed more
code from mouse.cxx than it added, which has to count for some
elegance points.
Oh yeah, I forgot to send that one along. This one is my bug, I
goofed the precedence in the fgPanelVisible() function in panel.cxx
such that the panel was *always* visible if virtual cockpit was
enabled. Here's a replacement. I've modified the style from a single
boolean expression to an if-list, since that's more readable to my
eyes for expressions this big:
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.
to 10m after takeoff, but that doesn't really make sense any more,
especially if models are going to have interior views. Is there any
real saving in pushing the near plane out anyway?
was some confusion between degrees and radians which would lead to a huge
goal_view_offset value. The display would sit and spin for a *long* time
trying to wind it's way up to this large value.
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.

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).
These changes add to the "Add Waypoint" dialog so that you can see the entire
list in the pui dialog that you are adding to. Also made some minor changes
so that the autopilot is now activated (toward first waypoint target heading)
when a waypoint is added.
command will save *all* properties, rather than just those marked as
archivable. This feature was requested by Tony Peden to make it
easier to write documentation on the properties, but it should also be
useful for debugging. There is currently no default binding for the
command with the write-all parameter set to true.
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:

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.
actually very powerful when combined with factor and offset -- for
example, on the C310 model the nose wheel can now retract completely
before the doors start closing.
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.

a value in RPM. This gets the DC-3 propellers turning. The next type

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

This change obsoletes the existing /sim/model/*-offset-deg and
/sim/model/*-offset-m properties in the main property tree, and
replaces them with /offsets/*-deg and /offsets/*-m in the model
property file. The /path property in the model XML file is relative
to the XML file's location rather than FG_ROOT.
Added two new properties:

These are now supported in FGEnvironment as well, though they always
have the same value for now. They need to be hooked up to the FDMs.

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.
properties have been renamed from wind-(north|east|down)-fps to
wind-from-(north|east|down)-fps, and the FDMs modified appropriately.
No other changes should be visible unless FG_OLD_WEATHER is defined.
Attached are patches for adding the command line options to set initial
glideslope and climb rate. This was really easy to do as all the pieces
were in place. It works well with JSBSim because the trimming routine
finds the right throttle and elevator settings. It should work with
LaRCsim as well, but it has no trimming routine so there will be some
dynamics at startup. I don't know what YASim will do.

This means that if you are using this protocal to exchange data with a

Attached is a fix to add a short period of cranking time required
before the engine fires. I've also added a little hack to limit the
torque applied by the starter motor when the rpm is less than 10 in
order to avoid the rpm overshooting idle in the first time step when
the prop is producing very little resistance due to the low rpm.

- remove variable 'length' (isn't used anywhere)
- make process_command private (it isn't used anywhere outside, and it
shouldn't be)
- define buffers where they are needed (two places)
- comment out stale debug message (it doesn't buy anything, because the
contents are output two lines below, anyway)
- let every error message begin with "ERR ". This makes error messages
less beautiful, but easier to recognize for scripts. Every internet

output from error messages. (pop3 uses "-ERR ", smtp uses error codes,
etc.)

/sim/freeze/master is bound to the 'p' key via keyboard.xml, however,
/sim/freeze/fuel is not bound to anything at the moment so you must
change it via the external property interface, or specify an initial
value on the command line.
properties /sim/view/view-tilt-deg and /sim/view/goal-view-tilt-deg
control the tilt. There are (temporarily) keyboard bindings in the
base package for experimentation: Ctrl-O to tilt the view down, and
Ctrl-P to tilt the view up.
otherwise, the logic in FGEngine::ConsumeFuel breaks down and the
engine is starved when *any* feed tank is empty, rather than when all
feed tanks are empty.
FDM people. FlightGear now supports an unlimited number of fuel
tanks. Also added correct fuel-flow reporting for piston engines, and
tracked new features in SimGear property support.
other -- it is now possible to set properties at startup (such as an
autopilot altitude). The only user-visible change, other than the
fact that the properties work as they are supposed to, is that the
heading bug no longer starts at a random value.
function to allow property files as non-option parameters after the
options have finished (and added "--" to terminate options). It's now
possible to do something like
fgfs denver-am.fgd
or even
fgfs at-lax.fgd in-c310.fgd around-sunset.fgd
This works the same way as the --config option, but will be friendlier
for GUIs, where start-up situation files can now be associated easily
with FlightGear.
Changed _set_Accels_Pilot_Body to use FGAuxiliary::GetNpilot instead
of FGAuxiliary::GetPilotAccel. It looks like a similar change was
started but never finished, and there are artifacts still lingering.
With this change, the slip/skid ball now works reasonably on the C172
when in motion, but not at rest (that will have to wait for fixes to
the gear code).
