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.
Make an OSG file reader for .stg files.
New class flightgear::SceneryPager, which is a subclass
osg::DatabasePager to handle explicit delete requests.
Modify FGNewCache, FGTileEntry, and FGTileManager to use
SceneryPager. Mostly this involved removing the queues that talked to
FGTileLoader.
Calculate accurate tile timestamps from the time they are traversed in
the cull stage (which means that they are visible) instead of updating
them periodically.
Replace tile entry transform and range node with one LOD node
This fixes a race condition when teleporting somewhere outside of the
currently loaded scenery. Before, if there was no valid scenery, an
aircraft might end up at the center of the earth...
Instead of just reporting that the magic number, length, etc. of a
multiplayer packet is invalid, abort processing this packet. Also,
check if enough space remains to send a property string.
are not available out-of-the-box on all systems and keyboards, and should
therefore not be used in files committed to CVS. This makes them well
suited for local key bindings, as they aren't likely to get overwritten
with later releases. SDL supports Meta and Super, OSG supports only Meta,
and GLUT supports neither.

This uses the osgViewer infrastructure instead of setting up and osg::SceneView.
When the same change is made for glut, much of render.cxx can be deleted.
Some cleanup in tileentry.cxx, but mostly code to implement loading of tiles
and their models without reference to FGTileEntry or SGBucket structures.
Also, don't do deferred model loading; load them when the tile is loaded.
_material was uninitialized. This was causing a segfault with
as-yet-to-be-checked-in paging code; I don't know if it ever resulted
in a segfault with the old tile loader, but it certainly could have.
file. Possible uses of this functionality could include converting the
model to some other format or coordinate system for use in some other
visualization or simulation.
This is required to make sure the same letter key gets released,
which got the press event. (After Ctrl-press -> a-press -> Ctrl-release
a-release we want the Ctrl-a binding released, not the a binding.)
- add key listener interface for direct key access from Nasal space
This removes some jitter in cases where Nasal is used to set up view
parameters from FDM data, such as position and orientation. (The event
subsystem handles Nasal's settimer() calls.)
This was correct in the old repository and in revision 1.1 of the new,
but then broken in revision 1.2. After that, "lookat" and "lookfrom"
mode used different coordinate systems, and the "Adjust View Distance"
didn't work correctly in "lookat" mode.
