The new example, named osgviewerQtContext (because of deriving from GraphicsContext), works fine on Windows XP SP3 and Qt 4.5.0, with 4 widgets in QGridLayout and a popup window and 60Hz frame rate. I haven't tested it on Unix/Linux and Mac OSX yet. So any feedback from these platforms is appreciated. I wish this example be a useful complement to current osgviewerQt and osgviewerQtWidgets ones. :)
Some unfinished functionalities: inheritedWindowData, sharedContext, and more tests needed."

This has the effect of always compiling OpenThreads as a framework under OSX. The CMakeLists.txt that I use to be able to compile the non-framework version of OpenThreads is attached. I simply replaced the '!' replaced by a 'NOT' and added a MESSAGE to notify me when the .framework will be compiled."
in process: a wrong definition of the OSG_FATAL macro, and wrong logic
inside the KeySwitchMatrixManipulator::getDistance() function. I
believe both were slips."
META_OSGMANIPULATOR_Object macro to ensure these classes could work
with their wrappers, and a few naming styles should be changed as
well. Fortunately everything seems to compile fine under Windows and
my new Ubuntu system.
And I finally find the problem of the
serializers/osgTerrain/Terrain.cpp, it just missed an "osg::Group"
before "osg::CoordinateSystemNode" indicator. With the small fix
attached now VPB could generate terrain with osgt/osgb formats."

Remark: The value -1e-6 may be added (falsely) because of a rounding error.
The attached fix prevents assigning NaN values to the image.

Texture2DMultismaple as name suggests provides means to directly access subsamples of rendered FBO target. (GLSL 1.5 texelFetch call).
Recently I was working on deferred renderer with OSG, during that I noticed there is no support for multisampled textures (GL_ARB_texture_multisample extension). After consultations with Paul Martz and Wojtek Lewandowski I added Texture2DMultisample class and made few necessary changes around osg::FrameBufferObject, osg::Texture and osgUtil::RenderStage classes."
and from follow email:
"Fixed. According to ARB_texture_multisample extension specification multisample textures don't need TexParameters since they can only be fetched with texelFetch."
- compile errors on windows when compiled with UNICODE flag
- warnings for duplicate WIN32_LEAN_AND_MEAN. I think this should
better fixed by adding WIN32_LEAN_AND_MEAN to vcproj preprocessor
list."
latest OSG source code with Visual Studio 2010 express, without
setting too many options and without facing unexpected errors. But at
present, the compilation process will fail because the INSTALL project
'cannot find' generated DLLs while copying files. I have looked into
the build directory and found that the places of generated file
folders were just different from previous VS versions. In this case,
the old hack in OsgMacroUtils.cmake may become invalid:
MACRO(HANDLE_MSVC_DLL)
#this is a hack... the build place is set to lib/<debug or
release> by LIBARARY_OUTPUT_PATH equal to OUTPUT_LIBDIR
#the .lib will be crated in ../ so going straight in lib by
the IMPORT_PREFIX property
#because we want dll placed in OUTPUT_BINDIR ie the bin folder
sibling of lib, we can use ../../bin to go there,
...
ELSE(NOT MSVC_IDE)
SET_TARGET_PROPERTIES(${LIB_NAME} PROPERTIES PREFIX
"../../bin/${LIB_PREFIX}${LIB_SOVERSION}-" IMPORT_PREFIX "../")
ENDIF(NOT MSVC_IDE)
ENDMACRO(HANDLE_MSVC_DLL)
Here the prefix "../../bin" may need to be fixed. I just modified it to:
IF(MSVC_VERSION LESS 1600)
SET_TARGET_PROPERTIES(${LIB_NAME} PROPERTIES PREFIX
"../../bin/${LIB_PREFIX}${LIB_SOVERSION}-" IMPORT_PREFIX "../")
ENDIF()
It should keep compatible with old MSVC versions. There are similar
fixes in the SETUP_PLUGIN and SETUP_EXE macros. I haven't tested them
on more platforms.
