parameter in osg::Image. To support this Image::setData(..) now has a new optional rowLength parameter which
defaults to 0, which provides the original behaviour, Image::setRowLength(int) and int Image::getRowLength() are also provided.
With the introduction of RowLength support in osg::Image it is now possible to create a sub image where
the t size of the image are smaller than the row length, useful for when you have a large image on the CPU
and which to use a small portion of it on the GPU. However, when these sub images are created the data
within the image is no longer contiguous so data access can no longer assume that all the data is in
one block. The new method Image::isDataContiguous() enables the user to check whether the data is contiguous,
and if not one can either access the data row by row using Image::data(column,row,image) accessor, or use the
new Image::DataIterator for stepping through each block on memory assocatied with the image.
To support the possibility of non contiguous osg::Image usage of image objects has had to be updated to
check DataContiguous and handle the case or use access via the DataIerator or by row by row. To achieve
this a relatively large number of files has had to be modified, in particular the texture classes and
image plugins that doing writing.
the type of the virtual function ImageStream::getCurrentTime(), and with this fixing a compile and runtime error.
Changed time variables all to use doubles rather than float to be consist with the change to getCurrentTime().
the required header mathematics.h is not being included explicitly.
I have just included it, and verified that this also works with current
version 0.7, since the header is also available there."
"From David Glenn and Paul Martz. This change adds support for the NO_COLOR bit in the Vertex records' flags field. If NO_COLOR is set, and PACKED_COLOR is not set, the code will now properly default to using the face color at those vertices. See the osg-users thread "Open Flight characteristic not reflected in the current OSG" for more info."
and
"In consultation with David Glenn, it appears we needed to change a second file to correct how OpenFlight handles transparency when vertices have NO_COLOR. "
functionality when using Terrain::setVerticalScale. This was caused by
the following call sequence resulting in a lockup:
void Terrain::setVerticalScale(float scale)
CALLS dirtyRegisteredTiles();
void Terrain::dirtyRegisteredTiles(int dirtyMask)
SETS LOCK OpenThreads::ScopedLock<OpenThreads::Mutex> lock(_mutex);
and CALLS (on every tile) setDirtyMask(dirtyMask);
void TerrainTile::setDirtyMask(int dirtyMask)
CALLS _terrain->updateTerrainTileOnNextFrame(this);
void Terrain::updateTerrainTileOnNextFrame(TerrainTile* terrainTile)
SETS LOCK OpenThreads::ScopedLock<OpenThreads::Mutex> lock(_mutex);
******* PROBLEM - since lock has already been set! ********
The suggested fix submitted changes from using Mutex to ReentrantMutex.
"
You can now set a "intersection mask" and it will be used when looking for intersections.
So you can now easily "hide" some objects from manipulators."
I don’t have access to an OSX or Linux dev machine to make the changes required to the quick time plugin. This plugin will just default to returning 0."

for GraphicWindowsIOS.mm broke the compilation for OpenGL ES 1.x as
GL_DEPTH_COMPONENT32_OES is not defined for 1.x. I added a #define-guard."
Improved the computation of the light direction from non-dimensional mouse coords so that they now project onto a hemisphere making
the interaction more intuitive.
Added support into .vnc plugin for passing in the keywords "swap", "RGB", "RGBA", "BGR", "BGRA" as OptionString values to allow .p3d presentations to control
whether the pixelformat should be swapped or set to a specific format.
changed the shadow map texture assigment to StateSet so that it doesn't use OVERRIDE, enabling subgraphs to use the same texture unit for other textures if they so required.
tidied up indentation.
Motivation ;
When using PagedLODs, you don't always know the real size of loaded children,
If it occurs that they are out of predefined bounds, picking on the parts that are out of bound will fail
They also can be culled out too soon.
The problem often occurs with long object (roads).
I've modified LOD and ProxyNode to include this option."
and later email:
"Attached the UNION_OF_BOUNDING_SPHERE_AND_USER_DEFINED version
There are impacts on some serializers (dae, osgWrapper).
I haven't modified deprecated osg, since it's deprecated"

It solves a wrong sample format being set for audiostreams type S32 and F32, for the
enum AVSampleFormat (in include/avutil/samplefmt.h) doesn't match
enum SampleFormat (in include/osg/AudioStream) for anything but
SAMPLE_FORMAT_U8 and SAMPLE_FORMAT_S16

and follow up that address versioning issue
"I can find the change, avutil version 50.38.0 introduced a new header file:
libavutil/samplefmt.h
older versions use
libavcodec/avcodec.h
with the sampleformats without AV_
an intermideate fix with the FF_API_OLD_SAMPLE_FMT is removed from ffmpeg 0.8.3 so
I think this is the correct fix:
#if LIBAVUTIL_VERSION_INT < AV_VERSION_INT(50,38,0)
#define AV_SAMPLE_FMT_NONE SAMPLE_FMT_NONE
#define AV_SAMPLE_FMT_U8 SAMPLE_FMT_U8
#define AV_SAMPLE_FMT_S16 SAMPLE_FMT_S16
#define AV_SAMPLE_FMT_S32 SAMPLE_FMT_S32
#define AV_SAMPLE_FMT_FLT SAMPLE_FMT_FLT
#define AV_SAMPLE_FMT_DBL SAMPLE_FMT_DBL
#define AV_SAMPLE_FMT_NB SAMPLE_FMT_NB

So with the 3.0 api change we propose the following change:
- put OSG_EXPORT on the QueryGeometry class so that we get access to the getNumPixels method.
- Create a function called getQueryGeometry that returns a casted _queryGeode->getDrawable(). Or a function called getQueryGeode that returns _queryGeode."
The osgUtil::CullVisitor class will display an OSG_INFO notification when attempting to clamp the projection matrix with invalid near/var values. This usually appears when the scene graph is empty or all objects are culled. I don't think this scenario warrants having this message appear every frame. It makes it very difficult to debug other issues when this notification floods the output window.
I'd prefer to have the notification removed, but there might be legitimate cases where you want this displayed. Instead, I just disabled the output if the near/far values are equal to FLT_MAX (their initial values). This should at least prevent the notification for the common case where everything was culled."
"Here a patch that correct like the previous assign collada material name
to stateset."
and
"I changed how the collada reader set object name in osg. Current
implementation use collada ID to setup name. with this patch I use
collada name to setup name in osg object and if collada provide no name
I use as fallback ID. I am not sure we want this fallback.
The motivation of this change is that when an artist set names to its
objects and export to collada, I am not able to use those names in osg
to retrieve the node."
and
"Here the update of the file that fix the light id stuff"
