- /sim/aircraft can be set to package ID, including qualified
package ID. If not matching package is found, falls back to
traditional search of fg-aircraft for -set.xml files
Adapt to corresponding SG change to make SGMaterialLib be ref-counted,
and have the 'reload-materials' command notify the tile-manager of this,
so it can update the options struct it passes to new tiles.
Had to add this to FGGlobals, since it needs to be cleaned up
alongside the sound manager (which ideally it would be owned by,
but that's a change for another day)
Break some subsystem dependencies, by explicitly using properties to read the primary position, orientation and velocities. (Instead of directly accessing the primary model placement). This means a couple more globals can die.
Cache the parsed navigation and airport data in a binary file to reduce
startup times and memory consumption (since only referenced FGPositioned
elements are held in memory).
Data will be reimported when the mod-time of any input file is changed.
If a global file is changed (nav.dat, awy.dat, apt.dat, etc), the cache
will be completely rebuilt, which takes approximately 30 seconds on
moderate hardware. (Future work may reduce this).
Remove various hacks and make magvar work like a normal subsystem, as part of the environment manager. Fix the remaining users of the globals->get_mag accessor, and hence kill off the global pointer.
Sink the 2D panel logic into FGPanelNode, simplifying
renderer.cxx and a few other places. Also allows potential
for unloading / paging of 2.5D panels in the future.
Add helper to look for an aircraft branch path in multiple candidate locations.
Update the main subsystems to use the helper, and hence load from any aircraft dir.
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.
- 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.
* 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
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)
