79cb22eb06 Changed the view movement detection code so that it uses the
new CullVisitor::Identifier to indentifier cull traversals,
this enables the code to properly detect movement when
osgViewer::Renderer uses double buffering of SceneView.

e28f9a7d32 Added CullVisitor::Identifier to help with cull operations that require a consistent identifier for
cull traveresals when osgViewer::Renderer uses double buffering.

7cd74f0282 From Farshid Lashkari, "Another update. I added a LIMIT_NEAREST enum which implements your previous suggestion of rejecting bounding volumes further from the nearest existing intersection. I only implemented this for LineSegmentIntersector. I'd appreciate it if you could double check the math I added to LineSegmentIntersector::intersects() for checking if the bounding sphere is further away. The results of this are promising. I'm getting noticeable performance increase for line intersections with scenes containing many drawables.

d3d0859b4c From Piotr Gwiazdowski, "So there's config setting OSG_DISABLE_MSVC_WARNINGS which should
disable pragmas that turn off specific warnings for MSVC.
Unfortunately it's presence is only checked in osg/Export header,
making other Export headers disable warnings no matter what, which is
kind of incoherent.

My fix adds #include <osg/Config> to every Export header. I've also
unified checking whether to disable warnings to current osg/Export
way:
#if defined(_MSC_VER) && defined(OSG_DISABLE_MSVC_WARNINGS).

Attachment contains all changed Export files in their original locations."

b24353b12c From Rafa Gaitan and Jorge Izquierdo, build support for Android NDK.
"- In order to build against GLES1 we execute:
$ mkdir build_android_gles1
$ cd build_android_gles1
$ cmake .. -DOSG_BUILD_PLATFORM_ANDROID=ON -DDYNAMIC_OPENTHREADS=OFF
-DDYNAMIC_OPENSCENEGRAPH=OFF -DANDROID_NDK=<path_to_android_ndk>/

-DOSG_GL2_AVAILABLE=OFF -DOSG_GL_DISPLAYLISTS_AVAILABLE=OFF -DJ=2
-DOSG_CPP_EXCEPTIONS_AVAILABLE=OFF
$ make
 If all is correct you will have and static OSG inside:
build_android_gles1/bin/ndk/local/armeabi.

- GLES2 is not tested/proved, but I think it could be possible build
it with the correct cmake flags.
- The flag -DJ=2 is used to pass to the ndk-build the number of
processors to speed up the building.
- make install is not yet supported."

1d55efb721 From Michael Platings, I've added initial support to osg for glGetProgramBinary and glProgramBinary.

67ae23f2cf From Alexander Sinditskiy, "reason of this changes described in http://forum.openscenegraph.org/viewtopic.php?t=7596
and another problem is:
example osgkeyboard is not work (keys not highlight) if user have 2 keyboard layout native and english and current user layout is native

I try to explain my changes

we need something that is identify key without modifier keys and layout  -> this is UnmodifedKey

I think osg must have its own UnmodifiedKeys table. Code must be run same on different platforms. This can de guaranteed by UnmodifiedKeys table.

Mikhail Izmestev helped me. He implemented VirtualKey changes in GraphicsWindowX11"

bc6a94c5b3 From Michael Platings, "I've attached a fix for a subtle bug that causes animations (and quite possibly other things) to be serialized incorrectly.
For the following code:

#define MYMACRO(NAME) myOutputStream << #NAME;
MYMACRO(Group)

you would expect that "Group" would be output. However, as there are many overloaded operator<< functions, none of which take a const char* argument, the function that's actually called is operator<<(bool). Hence what actually gets output is "TRUE".
An actual example of this is in serializers\osgAnimation\Animation.cpp, WRITE_CHANNEL_FUNC2.

So the simple solution to this is to add operator<<(const char*), attached.

f61a6aa4e7 Refactored the way that the DatabasePager passes the Terrain decorator node onto the TerrainTile.
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.

I saw a very noticeable performance problem (60 fps -> 8 fps) in DrawThreadPerContext mode in an osgEarth application before this patch.

e5a9eaa711 From Tim Moore, "Here is initial support for uniform buffer objects. The binding between a buffer object and an indexed target is implemented as a new StateAttribute, UniformBufferBinding. I've included an example program based on the code in the ARB_uniform_buffer_object specification.
A few things remain to do:
* The binding between a uniform block in a shader program and a buffer indexed target number is fixed, like a vertex attribute binding. This is too restrictive because that binding can be changed without relinking the program. This mapping should be done by name in the same way that uniform values are handled i.e., like a pseudo state attribute;

* There's no direct way yet to query for the offset of uniforms in uniform block, so only the std140 layout is really usable. A helper class that implemented the std140 rules would be quite helpful for setting up uniform blocks without having to link a program first;

* There's no direct support for querying parameters such as the maximum block length, minimum offset alignment, etc. Having that information available outside of the draw thread would make certain instancing techniques easier to implement."

b523cb15c1 From Tomas Holgarth and Stephan Huber, "
attached you'll find the second part of the IOS-submission. It contains

* an ios-specific implementation of the imageio-plugin
* an iphone-viewer example
* cMake support for creating a xcode-project
* an updated ReadMe-file describing the necessary steps to get a
 working xcode-project-file from CMake

Please credit Thomas Hogarth and Stephan Huber for these changes.

This brings the ios-support in line with the git-fork on github. It
needs some more testing and some more love, the cmake-process is still a
little complicated.

You'll need a special version of the freetype lib compiled for IOS,
there's one bundled in the OpenFrameworks-distribution, which can be used."

e36c4d3a3b From Stephan Huber, "attached you'll find a proposal for handling multi-touch-events with
osgGA. My approach is to bundle all touchpoints into one custom data
structure which is attached to an GUIEventAdapter.

The current approach simulates a moving mouse for the first touch-point,
so basic manipulators do work, sort of.

I created a MultiTouchTrackballManipulator-class, one touch-point does
rotate the view, two touch-points pan and zoom the view as known from
the iphone or other similar multi-touch-devices. A double-tap (similar
to a double-click) resets the manipulator to its home-position.

The multi-touch-trackball-implementation is not the best, see it as a
first starting point. (there's a demo-video at http://vimeo.com/15017377 )"

bda7ef8179 From Wang Rui, "I've finally completed the static build support for dotosg wrapper and
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.

be9003d90c From Wang Rui, "The latest modification of osg/State uses the GLuint64EXT type, which
belongs to GL_EXT_timer_query and should be decalared to avoid
compiling errors if the extension is not supported. I've attached this
small fix."

68f37c4dcb From Tim More and Robert Osfield, implementation of ARB_timer_query based GPU timing stats syncronization.
Initial email from Tim : "I've implemented using a timestamp, available with ARB_timer_query and OpenGL 3.3, to gather GPU stats. This is nice because it can accurately fix the GPU draw time with respect to the other times on the stats graph, rather than having to estimate the wall time of the end of GPU drawing. This also prevents anomalies like the GPU phase starting before the draw phase..."
Changes to Tim's submission by Robert:  Removal of need for swap buffer callback in ViewerBase.cpp, by
integrating a osg::State::frameCompleted() method that does the stats timing collection.  Introduction of a
GraphicsContext::swapBuffersCallbackOrImplementation() method that calls the State::frameCompleted() and
the swap buffers callback or the swapImplementation as required.

b7cccf6258 Refactored the versioning of serializers so it now uses a _firstVersion and _lastVersion make it possible
to specify what range of versions support each serializer.

b8a94a6d4e From Wang Rui, "I'd like to submit my latest modification of the serialization IO
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.
