The DatabasePager now passes the Terrain pointer into the ReaderWriter's via osgDB::Options object,
rather than pushing a NodePath containing the Terrain onto NodeVisitor. This
change means that the DatabasePager nolonger needs to observer the whole NodePath and
will be lighter and quicker for it.
The change also means that ReadFileCallback can now run custom NodeVisitor's on the scene graph without
having to worry about TerrainTile's constructing scene graphs prior to the Terrain being assigned.
Also changed is the NodeVisitor::DatabaseRequestHandler which now requires a NodePath to the node that you wish
to add to rather than just the pointer to the node you wish to add to. This is more robust when handling scenes
with multiple parental paths, whereas previously errors could have occurred due to the default of picking the first
available parental path. This change means that subclasses of DatabasePager will need to be updated to use this new
function entry point.
* the glsl plugin now supports processing #includes. The file extension sets the shader type.
* the registry releases gl objects of the shared state manager

serialization libraries. My submission mainly includes:
1. Add two new macros USE_DOTOSGWRAPPER_LIBRARY and
USE_SERIALIZER_WRAPPER_LIBRARY. Applications using static OSG must
include corresponding static-link libraries and use these two macros
to predefine native format wrappers. Please see osgstaticviewer and
present3D in the attachment for details.
2. Add a LibraryWrapper.cpp file in each
osgWrappers/deprecated-dotosg/... and osgWrappers/serializers/...
subfolder, which calls all USE_...WRAPPERS macros inside. The
LibraryWrapper file is automatically generated by the
wrapper_includer.cpp (with some slight fixes), which is also attached
for your reference. The deprecated-dotosg/osgAnimation is not included
because it doesn't us REGISTER_DOTOSGWRAPPER to define its wrappers.
3. Modify the ReaderWriterOSG.cpp to prevent calling loadWrappers()
when static build.
4. An uncorrelated fix to Serializer and ObjectWrapper.cpp, which
ensures version variables of serialziers are initialized, and
serializers out-of-version are not written to model files.

functionalities. It includes two main parts: a version checking macro
for handling backward-compatiblity since 3.0, and enhencement of
current schema mechanism. I also change the option handling process to
use getPluginStringData(), and add new USE_SERIALIZER_WRAPPER macro in
the Registry header to allow for static-link usage as well.
The enhencement of schema machanism just tells the type of each
serializer while outputting them, such as:
osg::Group = Children:1
The meaning of the number can be found in the osgDB/Serializer header,
BaseSerializer::Type enum. It may help 3rdparty utilities understand
the structure of the wrapper and do some reflection work in the
future.
The new macro UPDATE_TO_VERSION can help indicate the InputStream (no
affect on the writer) that a serializer is added/removed since certain
OSG version. An example wrapper file is also attached. The
Geode_modified.cpp is based on the serializers/osg/Geode.cpp file
(hey, don't merge it :-), but assumes that a new user serializer
'Test' is added since version 65 (that is, the OSG_SOVERSION):
REGISTER_OBJECT_WRAPPER( Geode, ... )
{
ADD_USER_SERIALIZER( Drawables ); // origin ones
UPDATE_TO_VERSION( 65 )
{
ADD_USER_SERIALIZER( Test ); // a serializer added from version 65
}
}
All kinds of ADD_... macros following UPDATE_TO_VERSION will
automatically apply the updated version. The braces here are only for
typesetting!
While reading an osgt/osgb/osgx file, OSG will now check if the file
version (recorded as the writer's soversion, instead of previous
meaningless "#Version 2") is equal or greater than Test's version, and
try reading it, or just ignore it if file version is lesser.
And we also have the REMOVE_SERIALIZER macro will mark a named
serializer as removed in some version, with which all files generated
by further versions will just ignore it:
UPDATE_TO_VERSION( 70 )
{
REMOVE_SERIALIZER( Test );
}
This means that from version 70, the serializer Test is removed (but
not actually erased from the list) and should not be read anymore. If
the read file version is less than 70 (and equal or greater than 65),
Test will still be handled when reading; otherwise it will be ignored
to keep compatiblity on different OSG versions.
"
change was to use doubles for reading and writing matrices regardless of type of Matrix
being serialized.
Change does break backwards compatibility though, so code
path supporting original format has been left in for the
time being. However, this code is not reliable enough and
is over complicated compared to the simplified handling. Once
the new code has been bedded down for a while I'll remove this code block.
I also fixed a possible bug in osgDB::XmlParser that doesn't handle control characters (like " to ") when reading node attributes, because the writeWrappedString() and readWrappedString() now depend heavily on control characters. An additional improvement is that osgx now supports comments."
osgWidget::Input:
[Functional changes]
- Previously, the field would be filled with spaces up to its max length, and typing would just replace the spaces. Also, there was a _textLength variable that kept track of the real length of text in the field, since the osgText::Text's length just reflected the length of spaces+text entered. This was not great, as you could still select the spaces with the mouse and it just feels hacky. So I changed it to only contain the text entered, no spaces, and _textLength was removed since it's now redundant (the osgText::Text's length is used instead).
- Fixed the selection size which (visually only) showed one more character selected than what was really selected.
- Fixed selection by dragging the mouse, it would sometimes not select the last character of the string.
- Cursor will now accurately reflect whether insert mode is activated (block cursor) or we're in normal mode (line cursor) like in most editors.
- Implemented Ctrl-X (cut)
- Added a new clear() method that allows the field to be emptied correctly. Useful for a command line interface, for example (hint, hint).
- Mouse and keyboard event handler methods would always return false, which meant selecting with the mouse would also rotate the trackball, and typing an 's' would turn on stats.
[Code cleanup]
- Renamed the (local) _selectionMin and _selectionMax variables which are used in a lot of places, as the underscores would lead to think they were members. Either I called them selection{Min|Max} or delete{Min|Max} where it made more sense.
- Fixed some indenting which was at 3 spaces (inconsistently), I'm sure I didn't catch all the lines where this was the case though.
- Put spaces between variable, operator and value where missing, especially in for()s. Again I only did this where I made changes, there are probably others left.
The result is that delete, backspace, Ctrl-X, Ctrl-C, Ctrl-V, and typing behaviour should now be consistent with text editor conventions, whether insert mode is enabled or not. I hope. :-)
Note, there's a nasty const_cast in there. Why isn't osgText::Font::getGlyph() declared const?
Also, as a note, the current implementation of cut, copy and paste (in addition to being Windows only, yuck) gets and puts the data into an std::string, thus if the osgText::String in the field contains unicode characters I think it won't work correctly. Perhaps someone could implement a proper clipboard class that would be cross-platform and support osgText::String (more precisely other languages like Chinese) correctly? Cut, copy and paste are not critical to what I'm doing so I won't invest the time to do that, but I just thought I'd mention it.

I changed
_in->setStream( new std::stringstream(data) );
to
_dataDecompress = new std::stringstream(data);
_in->setStream( _dataDecompress );
Then when the destructor is of InputStream is called I delete the
dataDecompress stringstream.

was posted on osg-users. I would like to follow the suggestion of
Brendan and add a std::endl before the END_BRACKET in
ListSerializer::write().

the OutputStream/InputStream implementations, which was just finished
last weekend with a few tests on Windows and Ubuntu. Hope it could
work and get more feedbacks soon.
I've added a new option "SchemaData" to the osg2 plugin. Developers
may test the new feature with the command line:
# osgconv cow.osg cow.osgb -O SchemaData
It will record all serializer properties used in the scene graph, at
the beginning of the generated file. And when osgviewer and user
applications is going to read the osgb file, the inbuilt data will be
automatically read and applied first, to keep backwards compatibility
partly. This will not affect osgb files generated with older versions.
"
modifications of the osgShadow header naming styles as well. The
osgDB::Serializer header is also changed to add new Vec2 serializer
macros because of the needs of osgShadow classes. It should compile
fine on both Windows and Linux. But I have only done a few tests to
generate .osgb, .osgt and .osgx formats with these new wrappers."
few headers and the osgAnimation sources are also modified to make
everything goes well, including:
A new REGISTER_OBJECT_WRAPPER2 macro to wrap classes like
Skeleton::UpdateSkeleton.
A bug fix in the Seralizer header which avoids setting default values
to objects.
Naming style fixes in osgAnimation headers and sources, also in the
deprecated dotosg wrappers.
A bug fix for the XML support, to write char values correctly.
A small change in the osg::Geometry wrapper to ignore the
InternalGeometry property, which is used by the MorphGeometry and
should not be set by user applications.
The avatar.osg, nathan.osg and robot.osg data files all work fine with
serializers, with some 'unsupported wrapper' warnings when converting.
I'm thinking of removing these warnings by disabling related property
serializers (ComputeBoundingBoxCallback and Drawable::UpdateCallback),
which are seldom recorded by users.
By the way, I still wonder how would we handle the C4121 problem,
discussed some days before. The /Zp compile option is set to 16 in the
attached cmake script file. And is there a better solution now?"
now O(n) rather than O(nlogn) where n is the number of requests. The refactoring also cleans up the access of the
request lists so that the code is more readable/maintainable.
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.

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.
