1. Rewrite the reading/writing exception handlers to work like the ive
plugin exceptions.
2. Write a header writing/checking function in ReaderWriterOSG2.cpp,
which may help decide if the stream is ascii or binary. The
readInputIterator() function will return null pointer if the input
file is nither osgb nor osgt format, which indicates that the old .osg
format could be used here, in case we've merged the two plugins
together.
3. Add a new ForceReadingImage option in the InputStream, which will
allocate an empty image object with the filename if specifed external
image file is missed. It may be useful for format converting in some
cases.
4. Add new osgParticle wrappers, as well as some modification to the
osgParticle headers, for instance, change isEnabled() to getEnabled().
5. Some fixes to the osg serialization wrappers."
From Robert Osfield, refactor of Wang Rui's original osg2 into 3 parts - parts placed into osgDB, the ReaderWriter placed into src/osg/Plugin/osg and wrappers into src/osgWrappers/serializers/osg
1) Add getShadowComparison() accessor function to osg::Texture class
2) Modify ReaderWriterTiff::writeTifStream() and _readColor() (in Image.cpp) to handle pixelFormat==GL_DEPTH_COMPONENT as if it were GL_LUMINANCE
3) Modify the Texture classes of the ive and osg plug-ins so that they save/load the following Texture members: _use_shadow_comparison, _shadow_compare_func and _shadow_texture_mode
"
It adds new PrimitiveSet constants for the specific geometry shader primitive types :
- LINES_ADJACENCY
- LINE_STRIP_ADJACENCY
- TRIANGLES_ADJACENCY
- TRIANGLE_STRIP_ADJACENCY
It also adds some missing features to the glsl reader plug'in.

First Submission email from Gustav:
"This submission adds a --cache option to osgconv and osgviewer that enables setObjectCacheHint(osgDB::Options::CACHE_ALL); It greatly reduces memory usage when a .osg file has lots of external references with ProxyNode:s that points to the same file.
Options are also added to the osg plugin. The code was already mostly implemented but there was no way to change the options.
includeExternalReferences
writeExternalReferenceFiles
A counter is added to keep track if an external file has already been written down to avoid writing the same file over and over again. If it has already been written once then it is not written again.
The counter is added to the Output class in osgDB.
"
Second Submission email from Gustav:
"This is a continuation to my previous submission.
I noticed that the same problem that I fixed in ProxyNode.cpp for the osg plugin (external files being written over and over again) also existed in the ive plugin. I attached a submission where the ive plugin remembers which external files that have already been written and do not write them again."
Changes to the above done by Robert Osfield,
changed command line parameter to --enable-object-cache
changed set/get methods in osgDB::Output and ive/DataOutputStream.cpp to be s/getExternalFileWritten(const std::string&)
cleaned up set up of osgDB::Options.
Now we could correctly configure geometry shaders in osg files."
Notes from Robert Osfield, renamed the names of the parameters to be less GL centric and more human readable.
"1. Location: <OSG_SOURCE_ROOT>\src\osgPlugins\osg\Fog.cpp
Reason: ".osg" writter plugins output incorrected string for osg::Fog's Mode.
How to Fix:
Line 138 in Fog.cpp: case(Fog::LINEAR): return "NERVER";
Change to: case(Fog::LINEAR): return "LINEAR";
2. Location: <OSG_SOURCE_ROOT>\src\osgPlugins\ive\
Reason: ".ive" writter plugins missing to process "osg::Fog".
How to Fix:
(1). Line 86 in ReadWrite.h:
Add: #define IVEFOG 0x00001133
(2). In CMakeLists.txt
"SET(TARGET_SRC" section Add: Fog.cpp
"SET(TARGET_H" section Add: Fog.h
(3). In DataInputStream.cpp
Line 54,Add: #include "Fog.h"
Line 1185,Add: else if(attributeID == IVEFOG){
attribute = new osg::Fog();
((ive::Fog*)(attribute))->read(this);
}
(4). In DataOutputStream.cpp
Line 57,Add: #include "Fog.h"
Line 832,Add: // This is a Fog
else if(dynamic_cast<const osg::Fog*>(attribute)){
((ive::Fog*)(attribute))->write(this);
}
(5). Add newly created ive::Fog Object in Fog.h and Fog.cpp.
