and a later post the same osg-submissions thread:
"it's been a while since I have made the changes but I think it was due to problems with static builds of OpenThreads on windows. I was using
OpenThreads in a communication/synchronisation library (without
OpenSceneGraph). It seems I forgot to post a small change in the CMakeLists file of OpenThreads. If a user turns DYNAMIC_OPENTHREADS to OFF (static build) OT_LIBRARY_STATIC will be defined in the Config.
Without these changes a windows user will always end up with a "__declspec(dllexport)" or "__declspec(dllimport)" which is a problem for static builds."
And another post from Blasius on this topic:
"I tested with VS2005 and VS2008. For 32 bit everything works as expected. For x64 and VS2008 I could successfully do the cmake-configure and then the compilation but I had occasional crashes of cmTryCompileExec.exe (during the cmake-configure phase) which seems to be a cmake bug. With VS2005 and 64bit cmake does not set _OPENTHREADS_ATOMIC_USE_WIN32_INTERLOCKED although the interlocked functionality should be there. If I place the source snippet from the CHECK_CXX_SOURCE_RUNS macro to a separate sourcefile I can compile and run the resulting executable successfully. Forcing OPENTHREADS_ATOMIC_USE_WIN32_INTERLOCKED (on VS2005/x64) reveals a bug in "intrin.h" which seems to be fixed in VS2008 but not in VS2005.
In case anyone is interested the lines:
__MACHINEI(unsigned char _interlockedbittestandset(long *a, long b))
__MACHINEI(unsigned char _interlockedbittestandreset(long *a, long b))
__MACHINEX64(unsigned char _interlockedbittestandset64(__int64 *a, __int64 b))
__MACHINEX64(unsigned char _interlockedbittestandreset64(__int64 *a, __int64 b))
should be changed to:
__MACHINEI(unsigned char _interlockedbittestandset(long volatile *a, long b))
__MACHINEI(unsigned char _interlockedbittestandreset(long volatile *a, long b))
__MACHINEX64(unsigned char _interlockedbittestandset64(__int64 volatile *a, __int64 b))
__MACHINEX64(unsigned char _interlockedbittestandreset64(__int64 volatile *a, __int64 b))
The worst thing that can happen is that interlocked funtionality is not detected during cmake-configure and the mutex fallback is used.
Which reminds me another small glitch in the Atomic header so I attached a corrected version.
Why is the OT_LIBRARY_STATIC added to the config file? It is not needed anywhere.
OT_LIBRARY_STATIC is needed if you are doing static-builds on Windows. See my previous post on that.

a capping the number of PagedLOD to a sepcified maximum, with pruning of inactive
PagedLOD when the total number of inactive and active PagedLOD goes above the maximum.
To enable the mode set the env var OSG_MAX_PAGEDLOD to a value something like 1000.
To facilitate this possibility I have added a template copy constructor and a template assignment operator. These work for safe conversions like those in my previous example, but fail as desired for non-safe conversions since the template instantiation fails during the raw pointer copy/assignment.
The lack of this facility has appreciably handicapped development of generic algorithms applied to the scene graph, and I believe that this alteration will be welcomed by most of the community. If there are issues with antiquated compilers not supporting template member functions then perhaps a small piece of conditional compilation is in order.
I have made the change using the latest release version (2.6) as the base. The full file is attached.
I have not tested building the osg wrappers and the script binding code. I have tested the legal and illegal conversions of both copying and assignment to ensure that behave as expected on MSVC7.1, MSVC8, MSVC9, GCC 4.3."
This code will add two extra statistics options:
-Camera scene statistics, stats for the scene after culling (updated at 10 Hz)
-View scene statistics, stats for the complete scene (updated at 5 Hz)
Each camera and each view will expand the statistics to the right.
I also added the requests and objects to compile of the databasepager to the databasepager statistics.""
"Soft shadow mapping is basically the same as hard shadow mapping beside that

The optimization is based on the observation that matrix matrix multiplication
with a dense matrix 4x4 is 4^3 Operations whereas multiplication with a
transform, or scale matrix is only 4^2 operations. Which is a gain of a
*FACTOR*4* for these special cases.
The change implements these special cases, provides a unit test for these
implementation and converts uses of the expensiver dense matrix matrix
routine with the specialized versions.
Depending on the transform nodes in the scenegraph this change gives a
noticable improovement.
For example the osgforest code using the MatrixTransform is about 20% slower
than the same codepath using the PositionAttitudeTransform instead of the
MatrixTransform with this patch applied.
If I remember right, the sse type optimizations did *not* provide a factor 4
improovement. Also these changes are totally independent of any cpu or
instruction set architecture. So I would prefer to have this current kind of
change instead of some hand coded and cpu dependent assembly stuff. If we
need that hand tuned stuff, these can go on top of this changes which must
provide than hand optimized additional variants for the specialized versions
to give a even better result in the end.

when applying styles to a Label element the code below runs in a infinite loop.
The reason for this is that nothing increments the Reader "r" in the case when applying a style to label,

"I made several modifications:
* The cause of my errors was that my OSG source directory path contains spaces. To fix this issue I wrapped all paths with quotes, as stated in doxygen documentation.
* I also received some warning messages about deprecated doxygen settings, which I fixed by updating the doxygen file, i.e. running \u2018doxygen \u2013u doxygen.cmake\u2018. By running this command deprecated doxygen options are removed, some option comments have changed and quite some options have been added (I kept their default settings unless mentioned).
* I was surprised to find that the doxygen OUTPUT_DIRECTORY was set to \u201c${OpenSceneGraph_SOURCE_DIR}/doc\u201d, which does not seem appropriate for out of source builds; I changed this to \u201c${OpenSceneGraph_BINARY_DIR}/doc\u201d. (On the other hand, maybe a cmake selectable option should be given to the user?)
* Fixed two warnings I received about unexpected end-of-list-markers in \u2018osg\AnimationPath and \u2018osgUtil\CullVisitor due to excess trailing points in comments.
* Fixed a warning in osgWidget\StyleInterface due to an #include directive (strangely) placed inside a namespace.
* Fixed a warning in osg\Camera due to the META_Object macro that confused doxygen. Adding a semi-colon fixed this.
* Removed auto_Mainpage from the INCLUDE option, because I am positive that this file does not belong there; It never generated useful documentation anyway.
* I added the OSG version number environment variable to the PROJECT_NUMBER option so that the version number is now shown on the main page of generated documentation (e.g. index.html).
* Changed option FULL_PATH_NAMES to YES, but made sure STRIP_FROM_PATH stripped the absolute path until the include dir. This fixed an issue that created mangled names for identical filenames in different directories. E.g. osg/Export and osgDB/Export are now correctly named.
* Changed option SHOW_DIRECTORIES to yes, which is a case of preference I guess.

New attribute DatabasePager::_expiryFrames sets number of frames a PagedLOD child is kept in memory. The attribute is set with DatabasePager::setExpiryFrames method or OSG_EXPIRY_FRAMES environmental variable.
New attribute PagedLOD::PerRangeData::_
frameNumber contains frame number of last cull traversal.
Children of PagedLOD are expired when time _AND_ number of frames since last cull traversal exceed OSG_EXPIRY_DELAY _AND_ OSG_EXPIRY_FRAMES respectively. By default OSG_EXPIRY_FRAMES = 1 which means that nodes from last cull/rendering
traversal will not be expired even if last cull time exceeds OSG_EXPIRY_DELAY. Setting OSG_EXPIRY_FRAMES = 0 revokes previous behaviour of PagedLOD.
Setting OSG_EXPIRY_FRAMES > 0 fixes problems of children reloading in lazy rendering applications. Required behaviour is achieved by manipulating OSG_EXPIRY_DELAY and OSG_EXPIRY_FRAMES together.
Two interface changes are made:
DatabasePager::updateSceneGraph(double currentFrameTime) is replaced by DatabasePager::updateSceneGraph(const osg::FrameStamp &frameStamp). The previous method is in #if 0 clause in the header file. Robert, decide if You want to include it.
PagedLOD::removeExpiredChildren(double expiryTime, NodeList &removedChildren) is deprecated (warning is printed), when subclassing use PagedLOD::removeExpiredChildren(double expiryTime, int expiryFrame, NodeList &removedChildren) instead. "

(The attached also clarifies some notify messages, and corrects the comment when adding the handler in osgviewer.cpp)
I also remembered, the current architecture could allow a different CaptureOperation for each context, but currently the API only allows setting one CaptureOperation for all contexts. This could be improved if need be.

"I have taken the liberty of updating a few files so that there is no longer any derivation from std::vector. I have done this by adding a new file osg/MixinVector and by updating only two others: osg/PrimitiveSet and osg/Array. You will notice that this actually removes what is acknowledged as a \u2018hack\u2019 in osg/PrimitiveSet.
With the original code I did manage to find memory leaks with some compiler options on VC 8 and 9, as well as Intel compiler. I determined the leak existence by instrumenting the destructor code, and by use of a garbage collector as a leak detector (in a similar manner to the Firefox project). Hence in contrast to what I said originally, it is exhibiting symptoms on at least some platforms.

viewport settings in stereo mode. It seems that the SceneView::cull()
method will pass the full size viewport to the left/right
cullvisitors, instead of the modified stereo viewport. I made quite a
few changes to SceneView to fix the issue. The SceneView::cullStage()
method will now receive the viewport as an argument, instead of using
the global viewport. The SceneView::cull() method will pass the
modifed viewport to cullStage when rendering in stereo.
There are 2 new private methods computeLeftEyeViewport() and
computeRightEyeViewport() that will compute the stereo viewports. I
also modified the draw() function so it applies the correct viewport
to the prerender stages. These changes are only necessary for

GL_GENERATE_MIPMAP_SGIS and non power of two textures on NVidia 7800GT and
Nvidia linux drivers with the image size 720x576 and only get compile times
of 56ms, so the above half second speed looks to be a driver bug. With
Muchael's changes the cost goes done to less than 5ms, so it's certainly
an effective change, even given that Michael's poor expereiences with

multi-threaded paging, where the Pager manages threads of reading local
and http files via seperate threads. This makes it possible to smoothly
browse large databases where parts of the data are locally cached while
others are on a remote server. Previously with this type of dataset
the pager would stall all paging while http requests were being served,
even when parts of the models are still loadable virtue of being in the
local cache.
Also as part of the refactoring the DatabaseRequest are now stored in the
ProxyNode/PagedLOD nodes to facilitate quite updating in the cull traversal,
with the new code avoiding mutex locks and searches. Previous on big
databases the overhead involved in make database requests could accumulate
to a point where it'd cause the cull traversal to break frame. The overhead
now is negligable.
Finally OSG_FILE_CACHE support has been moved from the curl plugin into
the DatabasePager. Eventually this functionality will be moved out into
osgDB for more general usage.
ReaderWriter::ReadResult now has a FILE_REQUEST enum.
ReaderWriter::Options now has a s/getAsynchronousFileReadHint() parameter methods.

as yet does not handle async requests - handling everything syncronously.

get an excess Tab key report when switching back to an OSG
application (usually FlightGear :-). Although KDE has consumed
the Tab, it's sometimes still in the XKeymapEvent's key_vector,
and followed by a Tab KeyRelease event.
Avoid this artifact by
- asking for a "fresh" keymap (via XQueryKeymap()), rather than
using the unreliable(?) XKeymapEvent's key_vector, and by
- flushing all key events on focus-in (to avoid the KeyRelease)
After Super-press, Tab-press, Super-release, Tab-release (note
the wrong release order!) I still get an extra Tab event. But
this is not surprising and not exactly wrong either. Also it's
hard to avoid, as we can't see what happened to the keyboard

GUIEventAdapter::ModKeyMask, and the EventQueue ingored them as well.
The attached diff/archive adds the missing parts for Super/Hyper
modifier key support.
I'm aware that this might not be supported on all systems/keyboards
out of the box, but decided to submit it anyway because:
- developers are aware of differences between input devices
(Some mice have scroll wheels, others don't. Some have five or
more buttons, some have only one. Some keyboards don't have
numpads, some have AltGr, some don't etc.)
- even if someone relies on Hyper/Super in distributed software,
this is easy to fix and doesn't create lock-in conditions
- while the names Hyper/Super may only be common on X11, they are
just symbol names and not OS-specific
- even though some systems might not offer these additional modifiers
by default, it's likely that all of them have at least 8 modifier
levels internally, so it should only be a matter of OS configuration
to make them work
- having super/hyper available is useful to offer a user ways
to define local key definitions that are safe from collisions with
predefined "official" key assignments"

key, but it didn't pick up the initial state. So, if NumLock was on for
the OS at startup (LED on), it was still off for OSG. And the first
keypress turned the LED off, and NumLock on for OSG. The attached fix
picks up the state on every FocusIn, just like it was done in the last
commits for CapsLock. The difference is, that the NumLock mask isn't
standardized (e.g. 0x10 for Linux, and 0x80 for AIX), so we have to do
a reverse lookup (::rescanModifierMapping()).

osgViewer::StatsHandler and other handlers which allow you to change the

but useful in our context and possibly in others too."
The win32 pbuffer implementation returned an error unless both the
WGL_ARB_pbuffer and the WGL_ARB_render_texture functions were present.
This was too restrictive, as a pbuffer can usefully be created without
render-to-texture, e.g. for use with glReadPixels. The osg 1.2/Producer
pbuffers worked without RTT, and osgUtil::RenderStage has all the code to
handle both RTT and non-RTT pbuffers, doing a read and copy in the
latter case.
With these changes I have successfully tested the osgprerender example
on a graphics card which supports RTT, and one which doesn't. Plus
tested in my own application.
In order to aid diagnostics I have also added more function status
return checks, and associated error messages. I have included the win32
error text in all error messages output. And there were some errors
with multi-threaded handling of "bind to texture" and a temporary window
context which I have corrected.
These is one (pre-existing) problem with multi-threaded use of pbuffers
in osgViewer & osgprerender, which I have not been able to fix. A win32
device context (HDC) can only be destroyed from the thread that created
it. The pbuffers for pre-render cameras are created in
osgUtil::RenderStage::runCameraSetUp, from the draw thread. But
closeImplementation is normally invoked from the destructor in the main
application thread. With the additional error messages I have added,
osgprerender will now output a couple of warnings from
osgViewer::PixelBufferWin32::closeImplementation() at exit, after
running multi-threaded on windows. I think that is a good thing, to
highlight the problem. I looked into fixing it in osgViewer::Renderer &
osgUtil::RenderStage, but it was too involved for me. My own
application requirements are only single-threaded.

remain in pressed state after revealing, even if they are no
longer pressed on the keyboard. This can have bad effects,
especially if the stuck keys are modifier keys. One has to
press and release the stuck keys again to reset the wrong state.
The fix keeps track of all key presses and releases. On FocusOut
and UnmapNotify it releases all keys that are in pressed state,
and on KeymapNotify (following a FocusIn), it sets the currently
pressed keys again. To avoid confusion in the OSG-using application
normal keys are always reported released /before/ and pressed
/after/ modifier keys.
As current key states are returned as char[32] keymap by
XQueryKeymap and XKeymapEvent, this format is also used to
recognize modifier keys and for maintaining the current
internal key state. Functions to set/clear/query bits in
such a keymap are added.
The patch was extensively tested with osgkeyboard and
FlightGear under KDE and fvwm2. It was not tested on a
Xinerama setup or with multiple windows, but as _eventDisplay
is used throughout, there should be no problems. The patch also
makes the following changes:
- removes old and obsolete handling of modifier keys in ::adaptKey().
This wasn't only unused, but also wrong (and for that reason commented
out in revision 7066). The modifier states are actually handled
in ./src/osgGA/EventQueue.cpp (EventQueue::keyPress/keyRelease).
- fixes some spelling"
The modifications I made are very small but they are absolutely usefull to use osgIntrospection with visual studio 7.1 or 8 in debug modes.
This should also solve other minor common problems (converter memory leak, virtual destructor for PropertyInfo, etc...).
I choosed two function names : Reflection::uninitialize() and Type::reset(), this can of course be changed if someone has a better idea...
I made the changes against OSG 2.2.0 public release. I tested the result with VS 7.1, VS 7.1 SP1, VS 8.0 SP1 and AQTime 5.0 on Windows XP SP2... All 4 seem to agree : they detected memory leaks before and don't anymore.
Sorry I haven't take the time to test that on linux but the changes are so small I doubt there could be a problem... I let you check that on your side :-).
I hope this will help making OSG an even more wonderfull library."
Attached is a fixed version of OverlayNode.cpp. I fixed CustomPolytope::cut( osg::Plane ) method. Bug was apparent in such scenario:
Let P1 be some random frustum polytope
Let P2 be the polytope that was created from P1 bounding box (P2 contains P1 entirely)
Then ignoring precision errors: P1.cut( P2 ) == P2.cut( P1 ) == P1. But this condition was not always met. Cut failed when some of the polytope reference points happened to lie exactly on some intersecting planes in both P1 & P2 (plane distance was = 0).
I only use CustomPolytope for my shadowing stuff so I did not test how this affects rest of OverlayNode.cpp.

Also attached is a minor precision improvement for osg::Plane intersect method (double version).
----3----
I have also one observation regarding osg::Plane - There are two intersect vertices methods (float and double flavour):
inline int intersect(const std::vector<Vec3>& vertices) const
inline int intersect(const std::vector<Vec3d>& vertices) const
I guess osg::Plane won't compile when someone changes default vec3 typedef to vec3d. Shouldn't the first method be changed to use vec3f explicitly ? Ie:
inline int intersect(const std::vector<Vec3f>& vertices) const"
