SceneryPager singleton must not be removed while FGScenery is still alive,
so hold a reference to it in FGScenery, saving the pager from being
deleted first.
Aircraft could fall through the ground on scenery reload. Properly reset
the "sceneryloaded" flag to pause FDM processing while scenery is being
reloaded. Also stop processing some instruments while scenery is reloaded.
This way of scenery paging is really application code.
Now that the simgear stg loader is seperated from the paging
code, this appication specific paging can reside here.
May be at some time also use the spt stuff here.
Instead of PagedLOD nodes use ProxyNodes for models in
scenery tiles. This should lower the amount of PagedLOD nodes
in the active scene. Since the models are part of the to level
tiles they are then paged out once the tile is paged out.
When a model is not found in the custom scenery directories, load data
from base-package (instead of trying to access file "").
Also allow paged models to be loaded from custom scenery folders.
The usual 'modify code before checkin but past testing' Problem.
Return the elevation of the intersection result instead of the
elevation of the querys start point.
Priority scheme for tile loading/removing
Cleaner tile manager interface for AI/groundcache/...
Reduce start-up delay. Drop splash screen when inner scenery is available.
Be nice to osg loader: slow-down main loop while initial scenery is still loading.
Again, the previous commit did not complete for some reason.

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.
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.
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.
"the [...] patch (for fg) increases the time before invisible geometry (i.e.
geometry not inside the view frustrum) gets deleted. default was 10 seconds
which i am increasing to 2 minutes."
From Till:
i started the project at the end of february with a simple idea: move all
3d-model loading to the DatabasePager-thread. my first attempts looked
promising, though they were a little too optimistic (or naive?). the patch
has evolved a lot since.
currently it does the following things:
1. revive SGModelLib, move functions for xml-model-loading there
2. replace all calls to sgLoad3dModel with calls to either
SGModelLib::loadModel() or SGModelLib::loadPagedModel()
almost all models will be loaded by the DatabasePager. the few exceptions are:
your own plane, shared models in scenery, random objects, AIBallistic models.
3. simplify mode-loading functions (avoid passing around fg_root)
4. avoid supurious MatrixTransform nodes in loaded models
5. fix some memory leaks
Reindent to Stroustrup style.
Make FGPrecipitationMgr an SGSubsystem and remove all references to it
in main.cxx and renderer.cxx.
Use SGGeod::makeZUpFrame instead of a private function in
tileentry.cxx. Rewrite that function, WorldCoordinate, to use
makeZUpFrame too.
As discussed with Tim on irc: Here is a quick fix for the memory-hungry tile
manager. Due to bugs in FGNewCache, old tiles were never deleted.
I left the timestamp-updates in the cull-traversal. but imho things work
just as well when timestamps are updated in FGNewCache::insert_tile() and
FGNewCache::get_tile()
The LOD far range on the tile entry scenegraph node was initialized to
0. This meant that any traverals of active children that happened
before the tile manager updated the node would ignore the node
altogether. Among these is the groundcache traversal which was failing
at startup even though scenery was loaded.
Also added a function to dump scene graph nodes to files; very handy
in gdb.
