time' code paths. The problem may lead to skipped fdm updates at very high
frame rates. The most visible effect of that was that the aircraft
slips backwards wrt the forward moving carrier.
Remove unused stuff.

localtime() is once commented out in simgear/io/sg_binobj.cxx and
a warning says the it can screw up sim time. This is only because
localtime() isn't thread-safe (and its thread-safe cousin localtime_r()
isn't portable). As long as all timing is done in the main thread
(which is the case) there should be no problem. Otherwise we'd have
to implement a simple mutex locked wrapper.
* Some support for geometry information provided by the custom scenery
project. Current support is for AI groundnets and runway use files only
since this is a switch that involves a lot of data verification and
updating, during the transistion the actual path where the data can be
read from is user configurable. setting the property
/sim/traffic-manager/use-custom-scenery-data to true
will cause flightgear to read the ground networks from the scenery
directory (--{fg-scenery}/Airports/[I]/[C]/[A]/[ICAO].groundnet.xml to be
precise). Setting this property to false will retain the original
behvior.
* For departing aircraft, runway takeoff calculations will be done on the
basis of the performance database. For testing purposes, a performance
estimate for a heavy jet has been added.
This was lost when I stopped cloning the near camera to make the far
camera. The result was a lot of breakage, including explicit camera
configurations not working and various ordering issues too.
This seems to be accepted OSG usage for slave cameras. It's possible
that this order is important for rendering instruments that use RTT
textures on systems without frame buffer object support. I'm thinking
that the resulting bugs may be implicated in the "black rectangle" problem.
The near/far boundary, called "near-field", can be set to 0 which
disables the far camera and renders the whole scene using only one
camera. I'm hoping that this may be useful in resolving some
system-specific rendering bugs.
Various fixes were made to correctly render the scene using only the
near camera.
by frequency (which makes sense), and use the FGPositioned spatial data if
required. As a result, the marker beacon list is gone (since beacons are only
searched spatially). In the process, clean up various minor things - most
notably, all the 'airport-related' navaids (ILS, GS, LOC, and the beacons) now
store a FGRunway* instead of an airport id string. This is more precise, and
saves string allocations.
- updates how filtering is done on the various FGPositioned query functions - both spatial and ident-based.
- updates the KLN-89b / DCLGPS code to use FGPositioned for all Navaid/Airport queries.
me:
Add few include directives in globals.cxx to avoid such MSVC warning messages :
deletion of pointer to incomplete type 'FGAirportList'; no destructor called
deletion of pointer to incomplete type 'FGNavList'; no destructor called
deletion of pointer to incomplete type 'FGTACANList'; no destructor called
deletion of pointer to incomplete type 'FGFixList'; no destructor called
These functions are now called in fgOSMainLoop. The fgMainLoop
function was being called twice, which resulted in a slow-down, but
also caused the displayed frame rate to double!
free /models/model[*] slot and lets the model manager load the
model. The target address is returned under "property". Simple
use in Nasal:
fgcommand("add-model", props.Node.new({
"path": "Models/Fauna/cow.ac",
"latitude-deg": 16.234,
"longitude-deg": 48.321,
"elevation-ft": 300,
});
An "elevation-m" property can alternatively be used and overrides
the "elevation-ft" property.
Each of the properties "latitude-deg", "longitude-deg", "elevation-ft",
"heading-deg", "pitch-deg", and "roll-deg" can alternatively be used
with "-prop" suffix. Their values must then be property path strings
pointing to a node that can be changed at runtime to move the model.
coordinates that were set relative to the aircraft's position
are picked up before the view update rather than the next cycle.
This avoids ugly fluttering of "passengers" at higher speed.
Partition depth in CameraGroup:
Remove the ViewPartionNode scenegraph node. The split rendering of the
scene, done to avoid Z buffer precision problems, is now done by two
slave cameras of the viewer.
Rename FGManipulator to FGEventHandler.
Remove virtual member functions that aren't required for event handlers.
Begin using camera group properties to update cameras at runtime;
Initially only the viewport properties are used.
When no camera group is found in the property tree (the default),
create the properties for one. Expose the default window by name.
Add a test for Boost headers to configure.ac. Boost is now a
dependency.
Remove GLUT and SDL versions of the OSG graphics.
stabilize some of the odd artifacts we were hearing, that were especially
noticable in clean sound samples like the stall horn or the marker beacon
codes. The change still preserves the doppler effect and maintains the
good work of a previous developer figuring out how to align the model and
listener velocity vectors correctly.
This was a source of a spew of "NaN" error messages at night when the
sun is at a large angle to the zenith. I don't know why this wasn't a
problem before now.
By way of example, here's a patch to make the position init code (in fg_init.cxx) cleaner, partly thanks to the FGPositioned changes. It reduces the file size by 200 lines - virtually all of which was copy-and-paste. Once the remaining class (FGAirport) is converted to inherit FGPositioned, all the future patches should be like this - touching one or a few files at most.
This factors the start-offset logic out into a helper, which also does the final property setting (which has to happen on both the /preset and 'real' values). Using the accessors in FGPositioned, and the offset helper, a couple of cases become trivial (fix and nav) and others become much simpler.
Convert FGNavRecord to inherit FGPositioned. This is much more self-contained than the FGRunway change, since FGNavRecord already had good encapsulation of its state. However, it's a large diff due to moving around two nasty pieces of code - the 'align navaid with extended runway centerline' logic and the 'penalise transmitters at the opposite runway end' logic.
In general things are more readable because I've replaced the Navaid type enum, and the use of Robin's integer type codes, with switches on the FGPositioned::Type code - no more trying to recall that '6' is an outer marker in Robin's data. The creation code path is also pushed down from navdb into navrecord itself.
Convert FGRunway to be heap-based, and inherit FGPositioned. This is a large, ugly change, since FGRunway was essentially a plain struct, with no accessors or abstraction. This change adds various helpers and accessors to FGRunway, but doesn't change many places to use them - that will be a follow up series of patches. It's still a large patch, but outside of FGAirport and FGRunway, mostly mechanical search-and-replace.
An interesting part of this change is that reciprocal runways now exist as independent objects, rather than being created on the fly by the search methods. This simplifies some pieces of code that search for and iterate runways. For users who only want one 'end' of a runway, the new 'isReciprocal' predicate allows them to ignore the 'other' end. Current the only user of this is the 'ground-radar' ATC feature. If we had data on which runways are truly 'single-ended', it would now be trivial to use this in the airport loader to *not* create the reciprocal.
Here's part 2 - converting FGFix (the simplest one) to be both heap-based and inherit FGPositioned. One minor benefit from this is replacing some dangerous code in FGFixList which used to return the address of an iterator member ('&it->second'). To keep the diff a sensible size, I'm not updating the callers to use the richer FGPositioned types - i.e replacing separate lat/lon handling with SGGeod. I will make those cleanups, but in future patches.
Small patch fixing bugs I've encountered while getting the current CVS to build in MSVC.
* std::lower_bound was used with the key-type of a map, but lower_bound expects the value-type of the collection it works on, with is std::pair. MSVC seems to be more strict about this.
* Added an missing include statement.
* Replaced an rint() call with floor() (MSVC does not offer rint).
- Runways are now part of an airport, instead of a separate list
- Runways are no longer represented as a boring struct, but as a class
of their own.
-Improved runway access to unify various runway access methods.
CameraGroup supports cameras opened in different windows or in the
same window, with flexible view and perspective specification.
Clean up mouse click handling via osgViewer. Don't let any camera
"have focus;" this forces events to be reported in window coordinates
and simplifies life. Don't use the osgViewer::View::requestWarpPointer
method; instead use our own code which only deals with window
coordinates.
Make glut and sdl versions work with CameraGroup too.
I thought that this would fix the "black hole in the sky" problem,
which turned out to be caused by an OpenSceneGraph bug. Nevertheless
it is a simplification.
* experimental clean-up / reduction on two of the FG headers:
(I'm going to await feedback on the developers list before doing more of
these, to avoiding going over files multiple times, but in principle it
seems pretty straightforward.)
* final fixes for SG_USING_STD removal
- this exposed a bizarre issue on Mac where dragging in <AGL/agl.h> in
extensions.hxx was pulling in all of Carbon to the global namespace
- very scary. As a result, I now need to explicitly include CoreFoundation
in fg_init.cxx.
- change SG_USING_STD(x) to using std::x
SimGear change. It changes all the SG_xxxx to be the 'real' includes, and gets
rid of many #ifdef SG_HAVE_STD_INCLUDES. As an added bonus, rather than
replacing 'SG_USING_NAMESPACE(std)' with 'using namespace std', I just fixed
the small number of places to use std:: explicitly. So we're no longer polluting
the global namespace with the entire contents of std, in many cases.
There is one more 'mechanical' change to come - getting rid of SG_USING_STD(X),
but I want to keep that separate from everything else. (There's another
mechnical change, replacing <math.h> with <cmath> and so on *everywhere*, but
one step at a time)
PLETE_FUNCTIONAL from SimGear and FlightGear.
As a result, SG_HAVE_STD_INCLUDES is now *always* set, so I will get the boring
fixes for that done, but separately. I'm still auditing the other things in comp
ilers.h - there's a lot that can die now BORLAND is gone.
- remove the OSX_BUNDLE crap *I* introduced years ago - we're always a a bun
dle on Mac now.
- fix up the default fg-root on Mac to be FlightGear.app/Contents/Resources/
data - i.e the location used by the macflightgear.org distro, and indeed the obv
ious 'correct' location. Not sure why I didn't use that in the first place, back
in the day.
- remove the CPSForegroundEnable hack. For one thing, we're a bundle and don
't need it, and for another, osgViewer on Mac does the same logic using a newer,
public API rather than a hack into the OS.
- remove the strange logic for doing fgOSInit 'early' (in bootstrap rather t
han main) when running from the command line on Mac; again this is obsolete, and
no one seems to know why it was ever necessary. I guess it was an interaction w
ith SDL when running without a bundle.
- (not Mac related) remove obsolete code bracketed by ENABLE_PLIB_JOYSTICK a
nd USE_GLIDE (neither of which are ever set, even from config.h that I can see)
in main.cxx
