Move fgviewer code into fgfs binary. Its osgViewer-style main function is
called from bootstrap.cxx if the --fgviewer argument is passed to fgfs.
Use fgfs initialization functions in fgviewer codepath. Read
command-line arguments and autosave.xml.

The osgViewer needs to be "realized" so that, among other things, threading
will start. This is normally done by osgViewer::run, but we don't call
that.
Don't realize graphics contexts; Let osgViewer code do it. This way
osgViewer::isRealized returns the correct answer.
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.

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.
