Create a pick group for each object, instead of a single one. This
can be optimised in the future but this structure is backwards-
compatible with existing usage, which is more important.
Pick, knob and slider animations support additional object-names,
which are always invisible and untransformed (in the case of knobs/
sliders). These objects act to extend the hover/pick area, making small
switches and knobs more usable. (Especially for users with smaller
screens / windows).
Initial ground-work to support efficient updating of condition/expression results; allow collecting all the dependent property values from the hierarchy, so they can be observed. Also add a very small test-case for this.
Check for the 3rdparty dir in the parent of build dir, not the parent of the source dir. For the recommended build layout, this is the same location, but for super-builds using fgmeta it's not (and the source tree should not be touched).
If this causes anyone issues, please let me know, since it's possible more flexibility is needed to set the path explicitly.
Basic library infrastructure, catalog download/refresh, and package install,
uninstall and update. Disabled at cmake time by default, and not yet hooked
into FlightGear.
Will be used to support native Nasal commands, which was tricky with pure function pointers before. Can also be used to avoid some trampoline functions in the code, but this can happen gradually.
Support multiple backends, and make it thread-safe. Use an internal thread to push log entries to backends, to avoid blocking the submitting thread for any time.
Currently this fires on button release, but also after any mouse-wheel movement (since they are sent as buttons). This feels slightly wrong, but can't decide how a spring-loaded know would work, when interacting via the mouse-wheel. Comments welcome.
As part of this, pass the osgGA GUIEventAdapter down into the pick callbacks, which seems reasonable to me. If anyone can foresee issues with this, please let me know and I can adjust the API.
ENABLE_SOUND=0 now works when configuring SimGear, and libSimGearScene can be linked without OpenAL. However, more testing of FlightGear in this mode is needed before it's officially supported!
Since there's no external lock, it was impossible to check the queue was non-empty before a pop, without a race condition. To avoid this, tolerate an empty queue and return a default constructed value.
Remove duplicate members shared by SGSoundSample and SGSampleQueue (which inherits from it). Change SGSoundSample to expose some members as protected data for access by the sample-queue, and hence share nearly all the methods. Also remove 'inline' keyword from virtual methods.
Tolerate slightly malformed request URLs (no slash following the host specified), and use a better check when POST-ing to decide the request-body data source.
It's possible (and happens!) to have less than 2^16 vertices or tex-coords, but more than 2^15 objects (tris) with the same materials. This was breaking our version 7 vs version 10 detection logic. Pete found the issue, I'm simply committing a version of his fix.
It's common to use SGTime to calculate the the Julian Date, without providing time-zone information. Don't warn in these cases, since the behaviour is fine.
Allow subsystem init to be incremental, i.e requiring repeated init calls until a 'done' code is returned. Use this to support incremental init in groups and the manager. (It would also be possible to support it in an individual subsystem).
Note that if you use the existing init() calls, behaviour is unchanged.
At least one Linux distribution packager of FG has complained that we're bundling expat in our binaries. To keep them happy, add the option (-DSYSTEM_EXPAT=1 at cmake time) to use the system expat instead.
For the moment (and simplicity), this requires building SIMGEAR_SHARED (which is fired to on by selecting the option).
Clang was complaining that SGSky has virtual methods, but no virtual destructor. It turns out we're never subclassing SGSky - it's used directly. Hence, remove all the 'virtual' attributes from its methods.
CMake has never supported the MIPS compatibility headers, or indeed building using MIPSpro. If someone wishes to re-add MIPS/IRIX support, I'm hoping they will be using a compiler with functional standard library headers!
Imitate Q_UNSUED from Qt, and provide a Simgear 'unused var' warning suppression macro. Fix up one place where the previous warning suppression attempt (assigning to self) was still producing a warning under clang.
Always create only two SimGear libraries: SimGearCore and SimGearStatic, regardless of whether we're building static or shared. This requires an updated to FindSimGear.cmake module, for the static configuration.
Adapt the freealut code into a WAV-file reader. As a side-effect, it would now be possible to deploy WAV files compressed with gzip, since we use ZLib's gzread functions to read from disk.
Latest Xcode no longer searches /Library/Frameworks by default which exposed an issue here. Search for the header by the correct name to trigger special -F handling in cmake.
