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
This also fixes distortion weirdness in the osgviewer version. That
was caused by osg::GraphicsContext getting in the act on resize events
and adding its own scaling to the projectionOffset of slave cameras!
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
Turn OPENSCENEGRAPH_MAJOR_VERSION, OPENSCENEGRAPH_MINOR_VERSION and
OPENSCENEGRAPH_PATCH_VERSION into a single number for comparisons in the
preprocessor.
This fixes a bug that caused both the x and y values of the mouse to
be reset when the cursor was recentered due to hitting the screen
edge.
Based on a suggested patch from Stuart Buchanan
"This patch fixes the use of the keypad with numlock in the osgViewer
version of FlightGear."
"This also restores the handling of resize events while trying to stay
out of the way of the multiple display code."
FGManipulator.*:
"This patch works around a bug in OSG's handling of modifier keys. The
symptom of the bug is that modifier keys don't appear to be released."
fg_os_osgviewer.cxx:
"This patch fixes the test for support of cursor changes in OSG 2.0."
