they are written to disk, either inline or as an external file. Added support for
this in the .ive plugin. Default of WriteHint is NO_PREFERNCE, in which case it's
up to the reader/writer to decide.
The vertical separation not actually displayed as it is set. So some
display the up and down stereo images style will not be correct.
Someone may forget to change the "Horizontal" to "Vertical" after
copying and pasting the code from above HORIZONTAL_SPLIT code segment.
I've attached the file. By replacing the incorrect "Horizontal" to
"Vertical", the bug is gone.

occlusion query result is not ready for retrieval when the app tries to
retrieve it. This fix adds an application-level wait loop to ensure the
result is ready for retrieval. This code is not compiled by default; add "-D
FORCE_QUERY_RESULT_AVAILABLE_BEFORE_RETRIEVAL" to get this code.
Full, gory details, to the best of my recollection:
The conditions under which we encountered this issue are as follows: 64-bit
processor, Mac/Linux OS, multiple NVIDIA GPUs, multiple concurrent draw
threads, VRJuggler/SceneView-based viewer, and a scene graph containing
OcclusionQueryNodes. Todd wrote a small test program that produces an almost
instant crash in this environment. We verified the crash does not occur in a
similar environment with a 32-bit processor, but we have not yet tested on
Windows and have not yet tested with osgViewer.
The OpenGL spec states clearly that, if an occlusion query result is not yet
ready, an app can go ahead and attempt to retrieve it, and OpenGL will
simply block until the result is ready. Indeed, this is how
OcclusionQueryNode is written, and this has worked fine on several platforms
and configurations until Todd's test program.
By trial and error and dumb luck, we were able to workaround the crash by
inserting a wait loop that forces the app to only retrieve the query after
OpenGL says it is available. As this should not be required (OpenGL should
do this implicitly, and more efficiently), the wait loop code is not
compiled by default. Developers requiring this work around must explicitly
add "-D FORCE_QUERY_RESULT_AVAILABLE_BEFORE_RETRIEVAL" to the compile
options to include the wait loop."
when applying styles to a Label element the code below runs in a infinite loop.
The reason for this is that nothing increments the Reader "r" in the case when applying a style to label,
so I advance the reader when no match was found.
( To replicate the error apply style to any label)
replaced this:
while(!r.eof()) if(_styles[style]->applyStyle(t, r)) inc = true;
with this:
while(!r.eof())
{
if(_styles[style]->applyStyle(t, r))
inc = true;
else
r.advanceOverCurrentFieldOrBlock();
}
I tested it and it works well for me, I did not find any problems with it.
2. Added style support for Canvas element, event though there is no styles to apply yet.
It is usefull for someone who inherits from Canvas class to develop another element.
If applyStyle(Canvas) does not exist
there is no way to apply style to the element that inherited from Canvas element.
Added virtual
bool applyStyle(Canvas).
and in added call to apply style if the Object is of type Canvas:
StyleManager::_applyStyleToObject(osg::Object* obj, const std::string& style) {
...
else if(!std::string("Canvas").compare(c))
return _coerceAndApply<Canvas>(obj,style,c);

"I made several modifications:
* The cause of my errors was that my OSG source directory path contains spaces. To fix this issue I wrapped all paths with quotes, as stated in doxygen documentation.
* I also received some warning messages about deprecated doxygen settings, which I fixed by updating the doxygen file, i.e. running \u2018doxygen \u2013u doxygen.cmake\u2018. By running this command deprecated doxygen options are removed, some option comments have changed and quite some options have been added (I kept their default settings unless mentioned).
* I was surprised to find that the doxygen OUTPUT_DIRECTORY was set to \u201c${OpenSceneGraph_SOURCE_DIR}/doc\u201d, which does not seem appropriate for out of source builds; I changed this to \u201c${OpenSceneGraph_BINARY_DIR}/doc\u201d. (On the other hand, maybe a cmake selectable option should be given to the user?)
* Fixed two warnings I received about unexpected end-of-list-markers in \u2018osg\AnimationPath and \u2018osgUtil\CullVisitor due to excess trailing points in comments.
* Fixed a warning in osgWidget\StyleInterface due to an #include directive (strangely) placed inside a namespace.
* Fixed a warning in osg\Camera due to the META_Object macro that confused doxygen. Adding a semi-colon fixed this.
* Removed auto_Mainpage from the INCLUDE option, because I am positive that this file does not belong there; It never generated useful documentation anyway.
* I added the OSG version number environment variable to the PROJECT_NUMBER option so that the version number is now shown on the main page of generated documentation (e.g. index.html).
* Changed option FULL_PATH_NAMES to YES, but made sure STRIP_FROM_PATH stripped the absolute path until the include dir. This fixed an issue that created mangled names for identical filenames in different directories. E.g. osg/Export and osgDB/Export are now correctly named.
* Changed option SHOW_DIRECTORIES to yes, which is a case of preference I guess.

New attribute DatabasePager::_expiryFrames sets number of frames a PagedLOD child is kept in memory. The attribute is set with DatabasePager::setExpiryFrames method or OSG_EXPIRY_FRAMES environmental variable.
New attribute PagedLOD::PerRangeData::_
frameNumber contains frame number of last cull traversal.
Children of PagedLOD are expired when time _AND_ number of frames since last cull traversal exceed OSG_EXPIRY_DELAY _AND_ OSG_EXPIRY_FRAMES respectively. By default OSG_EXPIRY_FRAMES = 1 which means that nodes from last cull/rendering
traversal will not be expired even if last cull time exceeds OSG_EXPIRY_DELAY. Setting OSG_EXPIRY_FRAMES = 0 revokes previous behaviour of PagedLOD.
Setting OSG_EXPIRY_FRAMES > 0 fixes problems of children reloading in lazy rendering applications. Required behaviour is achieved by manipulating OSG_EXPIRY_DELAY and OSG_EXPIRY_FRAMES together.
Two interface changes are made:
DatabasePager::updateSceneGraph(double currentFrameTime) is replaced by DatabasePager::updateSceneGraph(const osg::FrameStamp &frameStamp). The previous method is in #if 0 clause in the header file. Robert, decide if You want to include it.
PagedLOD::removeExpiredChildren(double expiryTime, NodeList &removedChildren) is deprecated (warning is printed), when subclassing use PagedLOD::removeExpiredChildren(double expiryTime, int expiryFrame, NodeList &removedChildren) instead. "
use the osg::State::applyMode for enabling/disabling certain while
rendering the stencil mask. Previously some of these calls were
overriding the scene graph states because the global state was not
aware of this change.

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.
The following link shows a very comprehensive list of .mtl file options:

Attached is a patch that should fix spacey filenames and optional texture scale/offset. I have tested it with files I have that I modified to contain spaces in the texture filenames."
viewer.addEventHandler(new osgViewer::ScreenCaptureHandler(
new osgViewer::WriteToFileCaptureOperation("filename", "jpg")));
and the filename will be what you want. The WriteToFileCaptureOperation will add the context ID and the file number (if in SEQUENTIAL_NUMBER mode) to the file name.
(The attached also clarifies some notify messages, and corrects the comment when adding the handler in osgviewer.cpp)
I also remembered, the current architecture could allow a different CaptureOperation for each context, but currently the API only allows setting one CaptureOperation for all contexts. This could be improved if need be.
"
Notes from Robert Osfield, I've merged osgWidget trunk, and added/changed CMakeLists.txt file to make it suitable for inclusion in the core OSG, and moved imagery/scripts/shaders out into OpenSceneGraph-Data
1. Added options to control wether the osgUtil::Tessellator or osgUtil::TriStripVisitor are run. By default they still run just as before.
2. Added support for the Emissive material. The data was being read from the mtl file but was never being applied to the model.
3. This is the main bug addressed, when a model is read in with an alpha value specified like:
newmtl Material__8
Ns 24
d 0.33
illum 2
Kd 0.204 0.204 0.204
Ks 0 0 0
Ka 0.153 0.153 0.153
where the alpha value is d. The loader would then overwrite the alpha value when reading the diffuse, specular, and ambient colors. I have changed all the material color readers to only set the values they read and to use the default colors specified in the constructor of the obj class. With these changes, the obj reader now handles opacity correctly if the alpha value is specified before the material colo"
It check the data type of the image ( img.getDataType() ) and if it's GL_FLOAT :It save the tiff with float values.
Otherwise it does the same thing as before."
does not process I/O for osg::Light. Now I have fixed it as follows:
2. In DataInputStream.cpp, I add support code in DataInputStream::readStateAttribute
for osg::Light.
3. In DataOutputStream.cpp, I add support code in DataOutputStream::writeStateAttribute
for osg::Light.

* The header node is returned if it exists, even if the file does not contain a node hierarchy. The old behaviour returned a ERROR_IN_READING_FILE error.

to optimize away duplicate state with dynamic, static and unspecified DataVarience. By default
the code now optimizes away duplicate state with either static and unspecied state, previously
it was just handling static state.
