I have left the Texture::generateTextureObject functions intact as I'm not sure if/how it's used outside the core OSG. If you feel that compatibility isn't important in that area feel free to drop it.
While testing the build with OSG_USE_REF_PTR_IMPLICIT_OUTPUT_CONVERSION=OFF I found a compile error in GlyphGeometry.cpp that was entirely unrelated to the changes I've made. The fix is included in the patch.
There is one thing left to fix and that is Texture2D::SubloadCallback:

//GLbitfield mask = GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT;
This line was problematic since it produced incorrect result when let's say COLOR flag is serialized
it should be null as in Camera serializer or in a proposed BitFlagsSerializer
This line of code caused that whenever only GL_COLOR_BUFFER_BIT bit was written and on value read GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT was restored instead of GL_COLOR_BUFFER_BIT only.
//GLbitfield mask = 0; //this resolves the issue same as in camera
Also same bit-wise comparison bug was also present in write method.
-------------------------------------------------------------------------------------
As you can see there are total 3 bit mask serializers in OSG and all 3 had bugs so I decided to add ADD_BITFLAGS_SERIALIZER and replace USER serializers in osg::Camera, osg::ClearNode and osgText::TextBase. I have made sure that bitflags serializer does not break backwards-compatibility since it uses same code as user serializer does in all 3 cases.

probably caused by rounding errors because it is only in one spot. The

moved back. Expanding the the bounding box fixed the clipping bug."
Tweaked by Robert Osfield to expand it to a -1 to 1 unit box.
Actual clipping bug is not due to rounding errors but the shaders creating vertices outside the bounding box of the original input vertices

* it sorts primitives to keep "more complex" primitives first; maybe you'll prefer to have this as an option (but usually it should make more sense to pre-transform triangles before e.g. lines)
* currently, the visitor rely on TriangleIndexFunctor and does not take care of points and lines (see https://github.com/openscenegraph/osg/blob/master/include/osg/TriangleIndexFunctor#L124-130). This can lead to issues e.g. if you store the wireframe lines along with some triangles: the triangles will be reindexed but not the line. I've therefore added osg/include/TriangleLinePointIndexFunctor to index triangles, lines and points and derived VertexReorder from this class.
* to avoid issues, shared arrays are duplicated. However, in some cases (e.g. an UV channel shared in the geometry only) this is not required. I'm adding a SharedArrayOptimizer to optimize this: it looks for duplicated UVs before the array duplication and deduplicate arrays after.

algorithm consisting of two consequent phases :
- first phase is a GLSL shader performing object culling and LOD picking ( a culling shader ).
Every culled object is represented as GL_POINT in the input osg::Geometry.
The output of the culling shader is a set of object LODs that need to be rendered.
The output is stored in texture buffer objects. No pixel is drawn to the screen
because GL_RASTERIZER_DISCARD mode is used.
- second phase draws osg::Geometry containing merged LODs using glDrawArraysIndirect()
function. Information about quantity of instances to render, its positions and other
parameters is sourced from texture buffer objects filled in the first phase.
The example uses various OpenGL 4.2 features such as texture buffer objects,
atomic counters, image units and functions defined in GL_ARB_shader_image_load_store
extension to achieve its goal and thus will not work on graphic cards with older OpenGL
versions.
The example was tested on Linux and Windows with NVidia 570 and 580 cards.
The tests on AMD cards were not conducted ( due to lack of it ).
The tests were performed using OSG revision 14088.
The main advantages of this rendering method :
- instanced rendering capable of drawing thousands of different objects with
almost no CPU intervention ( cull and draw times are close to 0 ms ).
- input objects may be sourced from any OSG graph ( for example - information about
object points may be stored in a PagedLOD graph. This way we may cover the whole
countries with trees, buildings and other objects ).
Furthermore if we create osgDB plugins that generate data on the fly, we may
generate information for every grass blade for that country.
- every object may have its own parameters and thus may be distinct from other objects
of the same type.
- relatively low memory footprint ( single object information is stored in a few
vertex attributes ).
- no GPU->CPU roundtrip typical for such methods ( method uses atomic counters
and glDrawArraysIndirect() function instead of OpenGL queries. This way
information about quantity of rendered objects never goes back to CPU.
The typical GPU->CPU roundtrip cost is about 2 ms ).
- this example also shows how to render dynamic objects ( objects that may change
its position ) with moving parts ( like car wheels or airplane propellers ) .
The obvious extension to that dynamic method would be the animated crowd rendering.
- rendered objects may be easily replaced ( there is no need to process the whole
OSG graphs, because these graphs store only positional information ).
The main disadvantages of a method :
- the maximum quantity of objects to render must be known beforehand
( because texture buffer objects holding data between phases have constant size ).
- OSG statistics are flawed ( they don't know anymore how many objects are drawn ).
- osgUtil::Intersection does not work
Example application may be used to make some performance tests, so below you
will find some extended parameter description :
--skip-dynamic - skip rendering of dynamic objects if you only want to
observe static object statistics
--skip-static - the same for static objects
--dynamic-area-size - size of the area for dynamic rendering. Default = 1000 meters
( square 1000m x 1000m ). Along with density defines
how many dynamic objects is there in the example.
--static-area-size - the same for static objects. Default = 2000 meters
( square 2000m x 2000m ).
Example application defines some parameters (density, LOD ranges, object's triangle count).
You may manipulate its values using below described modifiers:
--density-modifier - density modifier in percent. Default = 100%.
Density ( along with LOD ranges ) defines maximum
quantity of rendered objects. registerType() function
accepts maximum density ( in objects per square kilometer )
as its parameter.
--lod-modifier - defines the LOD ranges. Default = 100%.
--triangle-modifier - defines the number of triangles in finally rendered objects.
Default = 100 %.
--instances-per-cell - for static rendering the application builds OSG graph using
InstanceCell class ( this class is a modified version of Cell class
from osgforest example - it builds simple quadtree from a list
of static instances ). This parameter defines maximum number
of instances in a single osg::Group in quadtree.
If, for example, you modify it to value=100, you will see
really big cull time in OSG statistics ( because resulting
tree generated by InstanceCell will be very deep ).
Default value = 4096 .
--export-objects - write object geometries and quadtree of instances to osgt files
for later analysis.
--use-multi-draw - use glMultiDrawArraysIndirect() instead of glDrawArraysIndirect() in a
draw shader. Thanks to this we may render all ( different ) objects
using only one draw call. Requires OpenGL version 4.3 and some more
work from me, because now it does not work ( probably I implemented
it wrong, or Windows NVidia driver has errors, because it hangs
the apllication at the moment ).
This application is inspired by Daniel Rákos work : "GPU based dynamic geometry LOD" that
may be found under this address : http://rastergrid.com/blog/2010/10/gpu-based-dynamic-geometry-lod/
There are however some differences :
- Daniel Rákos uses GL queries to count objects to render, while this example
uses atomic counters ( no GPU->CPU roundtrip )
- this example does not use transform feedback buffers to store intermediate data
( it uses texture buffer objects instead ).
- I use only the vertex shader to cull objects, whereas Daniel Rákos uses vertex shader
and geometry shader ( because only geometry shader can send more than one primitive
to transform feedback buffers ).
- objects in the example are drawn using glDrawArraysIndirect() function,
instead of glDrawElementsInstanced().
Finally there are some things to consider/discuss :
- the whole algorithm exploits nice OpenGL feature that any GL buffer
may be bound as any type of buffer ( in our example a buffer is once bound
as a texture buffer object, and later is bound as GL_DRAW_INDIRECT_BUFFER ).
osg::TextureBuffer class has one handy method to do that trick ( bindBufferAs() ),
and new primitive sets use osg::TextureBuffer as input.
For now I added new primitive sets to example ( DrawArraysIndirect and
MultiDrawArraysIndirect defined in examples/osggpucull/DrawIndirectPrimitiveSet.h ),
but if Robert will accept its current implementations ( I mean - primitive
sets that have osg::TextureBuffer in constructor ), I may add it to
osg/include/PrimitiveSet header.
- I used BufferTemplate class writen and published by Aurelien in submission forum
some time ago. For some reason this class never got into osg/include, but is
really needed during creation of UBOs, TBOs, and possibly SSBOs in the future.
I added std::vector specialization to that template class.
- I needed to create similar osg::Geometries with variable number of vertices
( to create different LODs in my example ). For this reason I've written
some code allowing me to create osg::Geometries from osg::Shape descendants.
This code may be found in ShapeToGeometry.* files. Examples of use are in
osggpucull.cpp . The question is : should this code stay in example, or should
it be moved to osgUtil ?
- this remark is important for NVidia cards on Linux and Windows : if
you have "Sync to VBlank" turned ON in nvidia-settings and you want to see
real GPU times in OSG statistics window, you must set the power management
settings to "Prefer maximum performance", because when "Adaptive mode" is used,
the graphic card's clock may be slowed down by the driver during program execution
( On Linux when OpenGL application starts in adaptive mode, clock should work
as fast as possible, but after one minute of program execution, the clock slows down ).
This happens when GPU time in OSG statistics window is shorter than 3 ms.

lists when drawing lots of batches and noticed that my program
generated a lot of unneeded glClientActiveTexture calls. Digging
deeper I found out it came from State::disableTexCoordPointer where
the function would call glClientActiveTexture but not
glDisableClientState because the geometry didn't have texture
coordinates for that channel. This is because in our scene there are
some geometries that have move than one uv channels making
State::_texCoordArrayList grow. Then the method
State::applyDisablingOfVertexAttributes() will call
disableTexCoordPointer multiple times.
I rearrange the method a little to combat this. Now the logic has the
same ordering as disableTexCoordPointersAboveAndIncluding which
already combats this."

- Added apply(Drawable) and apply(Geometry) to NodeVisitor
- Added accept(NodeVisitor) method to Drawable/Geometry
- Added traverse(NodeVisitor) to Geode which calls accept(NodeVisitor) on all Drawables
- Updated CullVisitor to use new apply(Drawable) to handle drawables. The apply(Billboard) method still manually handles the drawables since it is depends on the billboard settings. I needed to disable the traverse within billboard to prevent duplicate traversal of drawables.
- Update other osgUtil node visitors (GLObjectsVisitor, IncrementalCompileOperation, ..) to use new apply(Drawable) method.

ran into two issues.
At first you get a bunch of warnings that osg::ComputeBoundCallback
and osg::UpdateCallback were unsupported wrapper classes when
converting fbx models with skeletal animation to osg(t/b).
The second issue was that when reading, the readers fail to read the
ComputeBoundCallback and UpdateCallback and set them to NULL which
messes up the RigGeometry.
Because a RigGeometry makes his own classes in the constructor it
might be preferable to not write them at all, because now those
classes are being made two times when reading a RigGeometry. But after
thinking about this that would place too much limits on them (you
won't be able to share or name them and save that information or make
a new inherited class from them and write that one) So I ended up
thinking the best way was to just write the files.

attributes in vec3b format. It looks like my compiler takes the wrong
overload and outputs integers instead of characters. The problem is
that vec3b is of type signed char and that is not the same as char (
see http://stackoverflow.com/questions/436513/char-signed-char-char-unsigned-char
) and visual studio 2013 will promote it to integer when choosing an
overload.
It looks like that the InputStream class already takes care of this
issue (if it didn't it would have read everything ok and I would have
not even stumbled upon this bug. :) )"
There was code in the osgViewer/Viewer.cpp and osgViewer/CompositeViewer.cpp that transformed the Y-coordinates of an event. The code in the composite viewer did however miss the touch-data of the event. I thought that it should really be the GUIEventAdapter that should know about this, and hence I added the
GUIEventAdapter::setMouseYOrientationAndUpdateCoords which is re-computing the coordinates. First I simply added a boolean to the setMouseYOrientation function:
setMouseYOrientation( MouseYOrientation, bool updatecooreds=false );
but then the serializer complained.
This function is called from both the Viewer and the CompositeViewer. We have not tested from the viewer, but I cannot see it would not work from visual inspection.
The other change is in MultiTouchTrackballManipulator::handleMultiTouchDrag. I have removed the normalisation. The reason for that is that it normalised into screen coordinates from 0,0 to 1,1. The problem with that is that if you have a pinch event and you keep the distance say 300 pixels between your fingers, these 300 pixels represent 0.20 of the screen in the horizontal domain, but 0.3 of the screen in the vertical domain. A rotation of the pinch-fingers will hence result in a zoom in, as the normalised distance is changing between them.
A consequence of this is that I have changed the pan-code to use the same algorithm as the middle-mouse-pan.
The rest of it is very similar from previous revision, and there has been some fine-tuning here and there.

To the Lua plugin added support for assigned lua functions to C++ osg::Objects via the new osg::CallbackObject mechanism. To invoke the scripts function from C++ one must get the CallbackObject and call run on it.
Renamed ScriptCallback to ScriptNodeCallback to avoid possibly confusion between osg::CallbackObject and the ScriptNodeCallback.
One solution is naturally to create a new class that would inherit the osg::ComputeBoundVisitor, and use that. I don't like that idea as the ComputeBoundVisitor does actually have what I need - it is only hidden in a protected function.
I am therefor suggesting a slight generalization of the ComputeBoundVisitor with the attached patch, which is tested.
The patch has two parts:
we add applyBBox() so that one can use that in a customized traverse-function and add a bbox to the visitor. I considered calling this function expandByBBox(), but I though applyBBox was better.
The MatrixStack is made available to the outside world. That enables a traverse-function to do whatever it wishes.
I do actually only need one of the two, as I can implement what I wish either way, but adding getMatrixStack() will make more generic expansions possible.

From Robert Osfield, changed the name of the new applyBBox(..) method to applyBoundingBox(..) to keep it's naming more consistent with the rest of the OSG.
I added a new tag to p3d called forward_touch_event_to_device and renamed the existing forward_event_to_device to forward_mouse_event_to_device. This new tag will transmit touches to the virtual trackpad as touch events. I added the MultitouchTrackball to the p3d-app so zooming and moving a model remotely should now work, if you use forward_touch_event_to_device. I kept (and fixed) forward_mouse_event_to_device for background compatibility, so old presentations works as in previous versions, without the ability to zoom + scale. of course.
forward_touch_event_to_device needs some more testing, (e.g. with image-streams and keystone, afaik there’s no support for touch-events...) but for a first version it works nice.

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."
To make easier "lazy apply" on the customer OpenGL shaders, the easiest way was to add an accessor to current OSG state's UniformMap.
I've also added accessors for modes and texture, since it could be usefull in the same way.
All methods are const, so I think there is no side-effects."
I've also checked the modified files still build ok with other
compilers (Linux gcc, Windows Visual Studio).
osgDB/OutputStream.cpp and osgPlugins/lws/SceneLoader.cpp require
stdlib.h for atoi use.
In osg/Uniform.cpp the compiler complains that base_class is unknown
unless I add a class name qualifier.
Not a build fix, but I spotted a typo in osgUtil/SceneView."
Provided are lua, python and V8 (for javascript) plugins that just open up enough of a link to the respective libs to run a script, there is no scene graph <-> script communication in current implementation.
