Many IDEs will capture the output of processes and highlight stderr messages in red. After upgrading from OSG 1.2, I was noticing that none of the error messages were being highlighted, which I find quite useful."
This was already possible for .frag and .vert so there's no reason why it shouldn't be possible for .geom.
I also changed the alignment of some extension aliases so the file looks a bit better now, but it's up to you if you want to merge that or not.

"Here is a small fix in the eventTraversal() function of both viewer
and composite viewer class.
if (getCameraWithFocus())
{
if (getCameraWithFocus()!=getCamera()) // Newly added
{
osg::Viewport* viewport = getCameraWithFocus()->getViewport();
osg::Matrix localCameraVPW =
getCameraWithFocus()->getViewMatrix() *
getCameraWithFocus()->getProjectionMatrix();
if (viewport) localCameraVPW *= viewport->computeWindowMatrix();
osg::Matrix matrix( osg::Matrix::inverse(localCameraVPW) *
masterCameraVPW );
osg::Vec3d new_coord = osg::Vec3d(x,y,0.0) * matrix;
x = new_coord.x();
y = new_coord.y();
}
...
}
I put an additional conditional statement here to ensure that
_cameraWithCamera and _camera are different, otherwise it's no need to
calculate the transition matrix from main camera to focus camera. The
excess calculations of 'matrix' and 'new_coord' may cause
floating-point error and return a slightly wrong result other than an
identity matrix. It seems OK in most cases but will be still pain when
there is little difference between two mouse moving events. "
- Replaced exceptions with assert() or OSG_NOTIFY
- Replaced osg::notify() with OSG_NOTIFY
- Changed braces and tabs to fit OSG coding convention
- Cleaned a few things in code (names, added deallocations upon error)"
currently only Debug appends "d" so the Release and MinSizeWithDebInfo
(and MinSizeRel) all produce the same filenames. This set of changes
lets each build type have a cmake defined string appended, defaulting
to Release none, Debug d, RelWithDebInfo rd, MinSizeRel s. But a user
still can have Release, RelWithDebInfo, and MinSizeRel to produce the
same filenames. It does so by setting the preprocessor define
OSG_LIBRARY_POSTFIX in src/osgDB/CMakeLists.txt to one of the
previously defined cmake variables CMAKE_DEBUG_POSTFIX
CMAKE_RELEASE_POSTFIX CMAKE_RELWITHDEBINFO_POSTFIX
CMAKE_MINSIZEREL_POSTFIX. This method cuts down on the #ifdef _DEBUG
#else preprocessor directives in Registry.cpp as the extension is
always passed in OSG_LIBRARY_POSTFIX. That and __MINGW32__ didn't
have the _DEBUG check which looks like a bug."
And by refactoring a bit of code, I may have fixed some StateSets related bugs (was ignoring StateSets for osg::Groups).
I also added support for Billboard's points, so now "osgconv lz.osg lz.3ds" has an acceptable output. However, there is no rotation depending on billboards' axis, hence the notice "Warning: 3DS writer is incomplete for Billboards (rotation not implemented).". You may want to remove this notice (or lower the notify severity) if you feel 3DS doesn't have to handle such rotations.
The attached archive contains 3 files from 3DS plugin, against rev. 11162.
Please note there is still the textures issue for cow.osg. I guess it's because it's not a "flat, dummy and standard" texture in slot 0... That is to say the only thing the writer can handle at the moment. I guess I won't address this soon.

and
"I've detected and fixed another bug in 3DS writer: support for automatic splitting of meshes having >65k faces/points was buggy (was deleting faces).
Here is my four 3DS modified files (in a ZIP), against rev. 11193, including previous fixes AND Stephan's fix about relative filenames."
using osgDB::XmlParser. The extension for XML-formatted scenes is
.osgx, corresponding to .osgb for binary and .osgt for ascii. It could
either be rendered in osgviewer or edited by common web browsers and
xml editors because of a range of changes to fit the XML syntax. For
example, the recorded class names are slight modified, from
'osg::Geode' to 'osg--Geode'.
To quickly get an XML file:
# ./osgconv cow.osg cow.osgx
The StreamOperator header, InputStreram and OutputStream classes are
modified to be more portable for triple ascii/binary/XML formats. I
also fixed a bug in readImage()/writeImage() to share image objects if
needed.
The ReaderWriterOSG2 class now supports all three formats and
reading/writing scene objects (not nodes or images), thanks to
Torben's advice before.
"
The options where not passed on to the image reader plugins when reading the new osg2 format files, so I added the options to the osgDB.:readImageFile function call.
"
absolute filenames for the texture images.
The attached change should fix this by at first looking at the absolute file
name to load a texture and then, if that fails, strip away any paths to try
that again with the bare file name.
The change also fixes a possible exception that could be triggered by an out
of bounds std::string access which is now avoided by using functions from
osgDB/FileUtils.
The change is based on rev 11161."
