I'm not sure if the IVE was simply generated incorrectly, or if the Image::getTotalSizeInBytesIncludingMipmaps() was modified since the file was generated. Either way, I added a simple check in the IVE loader so that it clears the mipmap offsets if the actual data size does not match the computed data size. This seems like a safe fallback since the mipmap data can be automatically generated, and it fixes the problem in my case.
Also, while looking into this issue, I noticed that the osgDB::InputStream class applies the serialized image allocation mode. However, since the serializer is allocating the image data itself, it seems like it should force the allocation mode to USE_NEW_DELETE.

set to "SCENE" in the file header. But if the file is stored and
then extracted again from an osga archive this header info is lost,
and the resulting file is just an "OBJECT". Possibly other plugin
operations would have the same effect. The osgt/osgb plugin won't
then return the scenegraph contents.
I have updated the osgt/osgb plugin to return a node from an "OBJECT"
file."
But the nested stream implementation for osga archive files doesn't
support seeking. So osgb files can't currently be used in an osga
archive e.g. if osgdem is used to output a osgb format database it
can't be packaged in an archive file, in the same manner that ive
files could.
I've added seek support to the osga nested stream implementation."
* fixed a bug with multi-touch and touch-id-generation on iOS and OS X. (will fix a bug reported by Colin Cochran, without ditching the existing logic)
* removed unnecessary warning-flagss when generating xcode-projects via cmake, will enable the usage of OSG_AGGRESSIVE_WARNING_FLAGS
* added support for 10.9 (OS X)
* new cmake-variable: IPHONE_VERSION_MIN, this will set the deployment-target (previously hard-coded) If you set the IPHONE_VERSION_MIN to something like 7.0 osg gets compiled also for 64bit (amd64)

the wrappers it contains. The registration creates a prototype
object for all of the wrapped classes. For some of the higher-level
classes this can be a bit heavy.
I noticed a problem with a model which required a single class from
osgSim. When osgdb_serializers_osgsim.so was loaded it registered
wrappers and created prototype objects for all of the osgSim classes,
including osgSim::ScalarBar. The constructor for that class creates
several drawables, and loads arial.ttf using the freetype plugin. I
don't need that, and don't even ship the font or plugin with my
application, resulting in an unexplained warning message loading
the model.
I've modified the ObjectWrapper class to defer the prototype object
creation until if & when actually required."

loading multiple VRML files in parallel. Christopher R. Baker has
detected this bug and crafted a patch. In addition, libcoin has to be
also built with the "--enable-threadsafe" option.
I copy here his report, extracted from
(https://bugs.launchpad.net/ubuntu/+source/openscenegraph/+bug/1211993)
and attach his fix. All credit is due to him:
«
There are three instances of a classical method-local-static
multithreaded initialization bug in the Inventor plugin for OSG that
trigger various memory faults when reading multiple VRML files in
parallel via osgDB::readNodeFile. These bugs are of the form:
static std::map<Stuff,OtherStuff> myHandyMap;
static bool once = true;
if(once) { ...fill myHandyMap; once = false }
... use myHandyMap;
To repeat: try loading multiple VRML files from multiple threads. The
liklihood of the bug depends on many factors, but my application, which
parallel-loads some dozens of small (<100K) VRML files on startup,
triggers this problem 25% of the time or more.
The attached patch (inventor-plugin-multithread.patch) rectifies this
problem by:
1 - Inheriting MyHandyMap from std::map, then
2 - Moving the map initialization into the derived constructor, which
3 - Is intrinsically protected from multithread issues by g++ (and is
part of the C++ standard), unless you pass -fno-threadsafe-statics,
which is strongly discouraged by the man page.

The delay between the 2 types of messages is more noticeable on Windows 8 and leads to serious disruptions in our application.
Mouse messages generated by touch input are only present for legacy support. I think they should be filtered out by OSG (real click events originating from a physical mouse will of course still go through).
This is what this patch does, according to this suggestion: http://msdn.microsoft.com/en-us/library/dd693088%28v=VS.85%29.aspx (third issue in this page)."

I found a bug on DDS ReaderWriter that generates a false positive on a guard for the size check on writing operation. This is due to a wrong imageSize computation that uses img->getImageSizeInBytes() method instead of img->getTotalSizeInBytes(), that actually ignores the r() dimension, contrariwise taken into account by the function ComputeImageSizeInBytes() later.
The line 1062 on file ReaderWriterDDS.cpp should be fixed with:
[code]unsigned int imageSize = img->getTotalSizeInBytes();[/code]

available. But this just checks if the fbo functions can be called.
It doesn't check if the OpenGL renderer supports fbos. For indirect
rendering on linux the client side capability may be different from
the display server, which can lead to mipmapped textures failing to
render. I've added a fbo extension check.

I double checked this with OpenFlight creator, and it seems the yaw is broken.
With my initial quaternion version is seems correct and if I change the
float cos_yaw = cosf(osg::inDegrees(yaw));
float sin_yaw = sinf(osg::inDegrees(yaw));
to be
float cos_yaw = cosf(osg::inDegrees(-yaw));
float sin_yaw = sinf(osg::inDegrees(-yaw));

Warning, can't assign attribute binding as no has been array assigned to set binding for.
I think those are ive's with bumpmaps, but I have not checked yet. The problem is in
OpenSceneGraph\src\osgPlugins\ive\Geometry.cpp
where the code tries to set Normalize and Binding for a missing Array.
I think that code can safely be skipped, considering the write function has a hardcoded write when the array is missing. (introduced in svn rev 13488)

But for glPrograms, in order to get all osg's uniform management system to work, I had to subclass osg::program::PerContextProgram.
Here is a modified version of this class, which add some "virtual" method to allow easy subclassing."
osgViewer::Renderer doesn't use these enum settings so now no longer has a calls StateSet::clear() or StateSet::setGlobalDefaults() on the osg::Camera's StateSet. Previously these were being
called and breaking the ability to attached state to Camera's StateSet.
1. Check the bit depth of the passed Image and return an error if not 8 or 16. (not fully featured, but still an improvement over hard coded 8bit for everything)
2. Endian swap 16bit image data when on a little endian architecture.

"The idea of this new OpenGL feature is :
- set RestartIndex = "n"
- draw elements strip
-> when the index is "n", the strip is "stopped" and restarted
It's very usefull for drawing tiles with a single strip and a "restart" at the end of each row.
The idea a an OSG StateAttribute is :
Usually we use to build geometry from code, because software modelers rarely support it (and 3d file formats doesn't support it) :
-RootNode <= "PrimitiveRestartIndex=0" // So now, we know that our restart index is 0 for all drawables under this node
|
- Drawable 1 : triangles => as usual
|
- Drawable 2 : triangles strip => as usual
|
- Drawable 3 : triangles strip + "GL_PRIMITIVE_RESTART" mode = ON => use the restart index
|
- Drawable 4 : triangles strip + "GL_PRIMITIVE_RESTART" mode = ON => use the restart index
|
- Drawable 5 : triangles strip => as usual
With a StateAttribute, it's easy for the developper to say "0 will be my restart index for all this object" and then activate the mode only on some nodes.
The main problem is if you set and restart index value which is not included in the vertex array (for exemple set restart index = 100 but you have only 50 vertex). There is no problem with OpenGL, but some OSG algorithms will try to access the vertex[100] and will segfault.
To solve this, I think there is two ways :
1/ add restart index in osg::PrimitiveSet and use this value in all algorithms. It's a lot of work, maybe dangerous, and it concern only a few situations : developpers who use this extension should be aware of advanced OpenGL (and OSG) data management
2/ use a StateAttribute, and choose a "correct" restart index. In my applications, I always use "0" as a restart index and duplicate the first vertex (vertex[0] = vertex[1]). So there is no difference for OpenGL and all OSG algorithms works properly.
"
"The attached file contains:
- a per-context read counter in GLBufferObject::BufferEntry
- a global client counter in BufferData
- the glue between Texture* and Image client counter
"
I think this is necessary on OpenGL 3.2+ since this is no more "default" locations in the OpenGL specs.
The default behaviour stay the same.
There is a few new methods on osg::State :
- resetVertexAttributeAlias : reset all vertex alias to osg's default ones
- set**Alias : set a vertex attribute alias configuration
- setAttributeBindingList : set the attribute binding list (allow to specify an empty list if you're using "layout" qualifier in glsl code to specify the bindings. This save some CPU operations)"

// A custom class
namespace CustomDomain {
class MyGroup : public osg::Group
{
public:
META_Node( CustomDomain, MyGroup );
void setMyName( const std::string& n );
const std::string& getMyName() const;
void setMyID( int id );
int getMyID() const;
...
};
}
// The serialization wrapper using a custom domain name
REGISTER_CUSTOM_OBJECT_WRAPPER( MyDomain,

{
ADD_STRING_SERIALIZER( MyName, std::string() );
{
UPDATE_TO_VERSION_SCOPED( 1 ); // Updated for a new domain version
ADD_INT_SERIALIZER( MyID, 0 );
}
}
Save the class instance as follows:
osgDB::writeNodeFile( *myGroup, "serializer_test.osgt", new osgDB::Options("CustomDomains=MyDomain:1") );
The output file will include the domain version definition and all the class data, and can be read back. We can also force setting the domain version by the CustomDomains option while reading the saved files. If we save the class instance without any options, MyID will be ignored because the default domain version is 0.
This may help third-party libraries like osgEarth to maintain their own serializers without regarding to the OSG soversion changes.
Another feature added is a more robust binary format, which in fact adds a size-offset at each block's beginning. When there are problems or unsupported data types while reading, we can now directly jump to the block end indicated by the offset value. So a .osgb file will automatically ignore bad data and read remains as normal (at present it will fail at all). This feature will not break the backward compatibility, and can be disabled by setting "RobustBinaryFormat=false" while writing out.
Hope these changes can work smoothly with present and future community projects. Maybe we should also consider have an osgserializer example to test and demonstrate all things we can do now."
