Gives the ability to define graphics settings via an XML file at
startup or later during runtime. Tracks if changes to graphics settings
required additional actions (eg, scenery reload or restart of the sim)
When a preset is active, and properties are modified, the system will
detect this and mark the preset as edited.
Overview:
Previously Flightgear always used a single osgViewer::Viewer(), which
inherits from both osgViewer::ViewerBase and osgViewer::View, giving a
single view window.
If CompositeViewer is enabled, we instead use a osgViewer::CompositeViewer
which contains a list of osgViewer::View's. Each of these View's can have
its own eye position, so we can have multiple different views of the same
scene.
Enable at runtime with: --composite-viewer=1
Changes to allow use of osgViewer::CompositeViewer:
Previously FGRenderer had this method:
osgViewer::Viewer* getViewer();
This has been replaced by these two new methods:
osgViewer::ViewerBase* getViewerBase();
osgViewer::View* getView();
If CompositeViewer is not enabled (the default), the actual runtime state
is unchanged, and getViewerBase() and getView() both return a pointer to
the singleton osgViewer::Viewer() object.
If CompositeViewer is enabled, getViewerBase() returns a pointer to a
singleton osgViewer::CompositeViewer object, and getView() returns a
pointer to the first osgViewer::View in the osgViewer::CompositeViewer's
list.
The other significant change to FGRenderer() is the new method:
osg::FrameStamp* getFrameStamp()
If CompositeViewer is not enabled, this simply returns
getView()->getFrameStamp(). If CompositeViewer is enabled it returns
getViewerBase()->getFrameStamp(). It is important that code that previously
called getView()->getFrameStamp() is changed to use the new method, because
when CompositeViewer is enabled individual osgViewer::View's appear to
return an osg::FrameStamp with zero frame number).
All code that uses FGRenderer has been patched up to use the new methods so
that things work as before regardless of whether CompositeViewer is enabled
or not.
We make FGRenderer::update() call SviewUpdate() which updates any extra
views.
Extra view windows:
If CompositeViewer is enabled, one can create top-level extra view windows
by calling SviewCreate(). See src/Viewer/sview.hxx for details.
Each extra view window has its own simgear::compositor::Compositor
instance.
Currently SviewCreate() can create extra view windows that clone the
current view, or view from one point to another (e.g. from one multiplayer
aircraft to the user's aircradt) or keep two aircraft in view, one at a
fixed distance in the foreground.
SviewCreate() can be called from nasal via new nasal commands "view-clone",
"view-last-pair", "view-last-pair-double" and "view-push". Associated
changes to fgdata gives access to these via the View menu. The "view-push"
command tags the current view for later use by "view-last-pair" and
"view-last-pair-double".
Extra view windows created by SviewCreate() use a new view system called
Sview, which allows views to be constructed at runtime instead of being
hard-coded in *-set.xml files. This is work in progress and views aren't
all fully implemented. For example Pilot view gets things slightly wrong
with large roll values, Tower View AGL is not implemented, and we don't
implement damping. See top of src/Viewer/sview.cxx for an overview.
OpenSceneGraph-3.4 issues:
OSG-3.4's event handling seems to be incorrect with CompositeViewer -
events get sent for the wrong window which causes issues with resize and
closing. It doesn't seem to be possible to work around this, so closing
extra view windows can end up closing the main window for example.
OSG-3.6 seems to fix the problems.
We warn if CompositeViewer is enabled and OpenSceneGraph is 3.4.
- Removed the ENABLE_COMPOSITOR CMake flag.
- Removed /sim/version/compositor-support.
- Removed miscellaneous branching to check if the Compositor is enabled.
- Removed custom resource loader since Compositor Effects are now located in $FG_ROOT/Effects.
- Removed splash screen warning.
- Only use the Compositor versions of CameraGroup and FGRenderer.
- Fix redout/blackout not appearing under certain circumstances.
If user specified --load-tape then failure to load it should be fatal to avoid
confusion. It also avoids needlessly overwriting a valid recovery tape if
/sim/replay/recovery-period is set.
Avoid filling up the logs when the launcher parses broken aircraft XML;
wait until the user actually pick one to fly with, before reporting
XML errors.
This is to avoid console/log spam from jetways.nas in particular,
which uses loadxml to probe for file existence, every 10 seconds. But
in general it seems useful to have this potentially be quiet, since
there is a result code.
This causes QApplication to become unhappy and crash, so use a
graceful exit via a new return code and FG_OPTIONS_EXIT instead.
Sentry-Id: FLIGHTGEAR-6B
FGCom was added to the wrong group, leading it to be shutdown after
FGSoundManager, and hence, after OpenAL wad closed, which causes
crashes.
Sentry-Id: FLIGHTGEAR-66
When the file path is not preset, check for this and don’t let
readProperties() fail with an exception, since this makes for very
noisy event reporting.
When starting at an airport, but not at parking or a runway, create
an empty AIFlightPlan, and ensure the AIManager code doesn’t choke on
empty FPs.
Add a unit-test which simulates the C172 tutorial reposition logic,
which is a little gnarly.
Handle the standard windows-3rd-party setup (used by fgmeta) with no
extra options, and also handle the slightly odd setup we use on Jenkins.
Try to tolerate all permutations of setting MSVC_3RDPARTY_ROOT to
different places in the hierarchy.
We no longer try to guess Boost_INCLUDEDIR by looking at parent dirs of
MSVC_3RDPARTY_ROOT, since this seemed kind of bad to me. Let’s try
it and see.
- fgfs --language=fr-FR now works as expected for the launcher (also with
--language=fr_FR as before): the value added by option --language to
the _languages member of FGLocale is normalized in "underscore" style
(e.g., fr_FR).
- Add-on translations must now use a hyphen in their property node names
in addon-metadata.xml (talking about children of <localized>): i.e.,
use for instance <fr-FR> there, not <fr_FR>. An exception
(addons::errors::error_loading_metadata_file) is thrown if one of
these nodes has a name containing an underscore.
Allow add-ons to define an FGData subdir, and support multiple —data=
command line arguments, to avoid the need to modify FG_ROOT (which might
be read-only). Allow additional data paths to be either higher or lower
priority than FG_ROOT, so that add-ons cannot replace files in FG_ROOT.
Suggested on the tracker, keep log files around longer. Currently we
keep the previous ten files.
Note we still don’t log for secondary running copies, since this would
violate the ‘only one copy can write to FGHome’ principle.

This avoids crashing when using Qt : we cannot call exit() safely since
QGuiApplication won’t shut down correctly. Instead throw a special
marker object and catch this in boostrap.
For an instance of this, see:
https://sourceforge.net/p/flightgear/codetickets/2070/
Was being shown before locale was selected, so always using default
translation. Fixed by deferring the dialog, and also added an assert
for debug builds, if trying to access translated string too early.
Ensure /orientation/heading-magnetic-deg, etc have a type of double
immediately. Showed up as a bug in the SenecaII, since the property
is created but has NIL value until the first update() call.
Re-work how position-init and ATC-manager work together to do
parking assignment and fallback (when the parking is unavailable).
Improve the logic for the reposition case, and teach ATC-manager about
reposition explicitly.
When the parking is unavailable, explicitly fall back to best-runway
selection in finalizePosition.
Add many additional position-init tests, to cover all of this.
Add translation macros for the text of the lock-file warning dialog,
and update the default text after some discussion on the devel list.
Also allow quiting the app, as an alternative option.
