//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. (see tester.cpp on how compatibility test was performed)"

Currently if you do this you get strange looking results as the colors are calculated for values in the centre of each color step, so if your steps are large, the colors are interpolated sigificantly (see screen grab of red, green and blue colors for illustration).
I've attached a fix which just uses the original color values whenever _numColors equals the number of actual defined colors in the ColorRange. I doubt anyone would want interpolated colors in these circumstances."

"I have found a "bug" in the new audio decoding code (actually I think the bug is in ffmpeg, but anyway it should be wise to protect the OSG plug-in about it). I am attaching a security check in FFmpegDecoderAudio.cpp.
If anybody is curious about the problem, it happens sometimes when decoding an AAC audio stream. It eventually includes a PCE block inside the AAC audio frame and then ffmpeg audio decoding function signals a "new_frame" with 1024 samples, but a null pointer instead of the audio data. It can be easily detected because in these cases number of channels is 0. Maybe this is the intended behaviour for ffmpeg, but I find it quite weird.

* 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.

The mac os sdk version is recognized by the current CMAKE script as 10.1 instead of 10.10 since it cuts the version string from the 4th place. I introduced a more reliable version checking based on splitting the returned version code into MAJOR MINOR and PATCH parts and reassemble the OSG sdk version afterwards.
I replaced the existing CMake code against the following (returning now version 10.10 as expected):
# Determine the canonical name of the selected Platform SDK
EXECUTE_PROCESS(COMMAND "/usr/bin/sw_vers" "-productVersion"
OUTPUT_VARIABLE OSG_OSX_SDK_NAME
OUTPUT_STRIP_TRAILING_WHITESPACE)
STRING(REPLACE "." ";" MACOS_VERSION_LIST ${OSG_OSX_SDK_NAME})
LIST(GET MACOS_VERSION_LIST 0 MACOS_VERSION_MAJOR)
LIST(GET MACOS_VERSION_LIST 1 MACOS_VERSION_MINOR)
LIST(GET MACOS_VERSION_LIST 2 MACOS_VERSION_PATCH)
SET(OSG_OSX_SDK_NAME "macosx${MACOS_VERSION_MAJOR}.${MACOS_VERSION_MINOR}")
Also i added the check for the new Version to some more find scripts.
Additionally the nil object in Objective C now seems to be equivalent with a null_ptr that cannot be passed as GLInt anymore. So i switched this in the PixelBufferCocoa.mm to pass a zero instead of nil.

My changes:
-------------------
- I changed the cmake files and added a toolchain for building OSG in Android. The toolchain is based on the one used at OpenCV. For building OSG for android you just need to do:
mkdir build_android_static_gles2 && cd build_android_static_gles2
cmake .. -DANDROID_NDK=<path-to-the-android-ndk>
-DCMAKE_TOOLCHAIN_FILE=../PlatformSpecifics/Android/android.toolchain.cmake
-DOPENGL_PROFILE="GLES2"
-DDYNAMIC_OPENTHREADS=OFF
-DDYNAMIC_OPENSCENEGRAPH=OFF
-DANDROID_NATIVE_API_LEVEL=15 # optional
-DANDROID_ABI=armeabim #optional
-DCMAKE_INSTALL_PREFIX=<path-to-the-install-path> #optional
make -j 8
make install
The OPENGL_PROFILE works as expected, changing it to "GLES1" it builds and links OSG using GLES1.
The DYNAMIC_OPENTHREADS/DYNAMIC_OPENSCENEGRAPH parameters also allows to build the dynamic libraries
- I also added some build fixes for android related to the texture formats and added some missing USE_OSG_SERIALIZER_WRAPPER in the osg serializer library to support loading osgb files in static."

The problem is that the readObjectFields method will add the object to the _identifierMap. So all the other instances of that image in the same file will be replaced by the created dummy object. In my fix this was an dummy image and I didn't notice it in our scene's, probably because it covered a small part of an object. In your fix the dummy object was not an image and that leads to a crash when something tries to use it as an image. I have attached a small fix for this bug.
