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."
Old behaviour: "abc.d/filename_no_ext" -> "abc"
New behaviour: "abc.d/filename_no_ext" -> "abc.d/filename_no_ext"
Attached file is against rev. 11158."
- OsgMacroUtils.cmake, SETUP_LINK_LIBRARIES macro : allow linking with debug/release external libraries
- osgQt/CMakeLists.txt : fix the linking to Qt librairies + linking to debug Qt librairies if found
- examples/ qt examples : linking to debug Qt librairies if found"
Attached you will find updates of the files to hopefully solve the warnings (in VS2005 only one warning occured). In addition I fixed a tiny bug that caused a crash with one of my test files."
This change should make it possible to delete PagedLOD's independantly from the DatabasePager, and also prevent issues of
consistency of the pager when subgraphs when are cached elsewhere in the application such as in the Registry filecache.
up vector to setViewMatrixAsLookAt(..) codes in osgShadow. This will addresses previous issues that occured when look vectors
co-incided with the hard coded up vectors.
Fixes in StandardShadowMap.cpp & MinimalShadowMap.cpp were made for spotlight issues. There were cases when further located spotlights were not shadowing properly.
Small tweak in DebugShadowMap & StandardShadowMap.cpp to not limit shadow maps to texture2D (which should also allow texture2D arrays and cube maps). I simply replaced ptr to osg::Texture2D with pointer to osg::Texture. Interpretation of this member could be now changed with change of shaders in derived classes. This may be useful for guys who override LispSM or MinimalBoundsShadowMaps techniques. Could be useful for implementation of PerspectiveCascadedShadowMaps technique for example.
ConvexPolyhedron.cpp & DebugShadowMap.cpp contain debug HUD tweaks.
Change in ConvexPolyhedron.cpp overcomes the regression problem with color per primitive binding which caused that shadow volume outlines stopped to draw. I simply changed PER_PRIMITIVE to PER_PRIMITIVE_SET and it works again.
Other adition is dump method I added to DebugShadowMap which can be used in shadow debugging mode to dump current frame shadow volumes & scene to osg file. It could be then loaded into viewer and freely examined from different angles (which is difficult inside the application if shadow adopts to view and projection). "
