Remark: The value -1e-6 may be added (falsely) because of a rounding error.

"
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.
"
CURL_LIBRARY_DEBUG and ZLIB_LIBRARY_DEBUG. Previously it linked the
debug version against the release libs, which was causing a hang when
running in debug mode on Windows."
modifications of the osgShadow header naming styles as well. The
osgDB::Serializer header is also changed to add new Vec2 serializer
macros because of the needs of osgShadow classes. It should compile
fine on both Windows and Linux. But I have only done a few tests to
generate .osgb, .osgt and .osgx formats with these new wrappers."
Mathieu Marache, he added the last missing piece to this puzzle.
I think it is safe to commit these changes to trunk, as the traditional
way via dylibs should work as before.
Here's some more info how to get frameworks:
With these modifications it is possible to compile frameworks on OS X,
when you set the Cmake-option OSG_COMPILE_FRAMEWORKS to true. If you
want to embed the frameworks in your app-bundle make sure to set
OSG_COMPILE_FRAMEWORKS_INSTALL_NAME_DIR accordingly.
You'll have to build the install-target of the generated xcode-projects
as this sets the install_name_dirs of the frameworks and plugins."
few headers and the osgAnimation sources are also modified to make
everything goes well, including:
A new REGISTER_OBJECT_WRAPPER2 macro to wrap classes like
Skeleton::UpdateSkeleton.
A bug fix in the Seralizer header which avoids setting default values
to objects.
Naming style fixes in osgAnimation headers and sources, also in the
deprecated dotosg wrappers.
A bug fix for the XML support, to write char values correctly.
A small change in the osg::Geometry wrapper to ignore the
InternalGeometry property, which is used by the MorphGeometry and
should not be set by user applications.
The avatar.osg, nathan.osg and robot.osg data files all work fine with
serializers, with some 'unsupported wrapper' warnings when converting.
I'm thinking of removing these warnings by disabling related property
serializers (ComputeBoundingBoxCallback and Drawable::UpdateCallback),
which are seldom recorded by users.
By the way, I still wonder how would we handle the C4121 problem,
discussed some days before. The /Zp compile option is set to 16 in the
attached cmake script file. And is there a better solution now?"
a byte order issue.
The problem is that osg::SwapBytes code has been copied from the old
plugin to the new one, but the latest lib3ds also incorporates code to
handle byte ordering in read & writing. So the net result is that the
swap is done twice.
The solution is simply to remove the custom osg code, and use the
stock lib3ds code. The attached files are against today's revision
11331. I've tested on Sparc & Intel.
"
- Fixed handling of MatrixTransforms (still doesn't support other Transforms types). Fixes things for OSG, DeepExploration, 3DSMax...
- Added support for writing double precision vertices by converting them.
- Added base code for future compatibility option (3rd-party apps that don't read animation data). See "DISABLE_3DS_ANIMATION" compile flag."
