After the changes that moved the GUI and HUD to a slave camera, the
texture-based fonts wouldn't display. The main fixes here are making
sure that the TXF textures are all loaded into the font cache early,
and explicitly setting the active texture unit in the GUI / HUD
drawImplementation.
Switch to defining PU_USE_NONE and providing our own callback
functions to pui for "get window" and "get window size." A new
WindowSystemAdapter class assigns ID numbers to windows for the
purpose of identifying them to plib; the window size can be extracted
from the osg::GraphicsContext class in all the different
implementations (osgViewer, glut, sdl).
Implement a GraphicsContextOperation that runs code in a particular
graphics context, perhaps in another thread, and provides an
isFinished() method to test if the operation has finished. This allows
us to initialize plib PUI properly if there are multiple graphics
contexts without using fgMakeCurrent(). fgMakeCurrent() can't work in
multi-threaded OSG configurations.
Eliminate fgMakeCurrent() and all its uses, either by using
GraphicsContextOperation or by seeing that it is not necessary.
Attach the GUI camera as a slave camera.
Don't manipulate the OSG state in the drawImplementation() functions
for SGHUDAndPanelDrawable and SGPuDrawable; it's not needed.
on the '*'-key, but allow to cycle it by setting
/sim/rendering/on-screen-statistics to "true"
- move that function to the Debug menu (no more key assigned!)
- add "print-statistics" menu entry
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
$ fgfs --version
2.0pre-20080314
FG_ROOT=/usr/local/share/FlightGear
FG_HOME=/home/foo/.fgfs
... assuming that VERSION in config.h is "2.0pre-20080314". Which it isn't.
Instead it's "1.0.0" since yesterday, and was "0.9.10" before that. This
has yet to be discussed, and I'll add the option to options.xml later.
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.
Makes it possible to start at a parking location defined in the AI/Airports/*/parking.xml files, using the parkpos command line option.
Note that the name to pass is the concatenation of the "name" and "number" fields in the xml.
This allows Nasal managed views thanks to the proximity of the
event manager (which executes Nasal loops). The io manager must
come after the view manager to avoid jitter in network replay.
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!
