* fixed a bug with multi-touch and touch-id-generation on iOS and OS X. (will fix a bug reported by Colin Cochran, without ditching the existing logic)
* removed unnecessary warning-flagss when generating xcode-projects via cmake, will enable the usage of OSG_AGGRESSIVE_WARNING_FLAGS
* added support for 10.9 (OS X)
* new cmake-variable: IPHONE_VERSION_MIN, this will set the deployment-target (previously hard-coded) If you set the IPHONE_VERSION_MIN to something like 7.0 osg gets compiled also for 64bit (amd64)
* cmake defaults now to the clang compiler if IPHONE_VERSION_MIN > 4.2
* cmake now sets some xcode-settings so the compiler uses the c++98-standard (clang defaults to c++11, w/o this I got a lot of linking errors)
* removed include-dir for avfoundation-plugin as not needed on OSX/IOS.
* enhanced the ios-example, will now show multitouch-information on a hud (similar to the osgmultitouch-example), and more importantly, will compile + link out of the box
* small enhancements for the osc-device-plugin (send only one msg for MOVE/DRAG, even if multiple msgs/event is enabled)
* better memory-handling for the zeroconf-plugin
* fixed a possible bug in the rest-http-plugin when receiving mouse-events.
* incorporated a fix from Colin Cochran "forwarded touch events are not transformed into the GL UIView“

the wrappers it contains. The registration creates a prototype
object for all of the wrapped classes. For some of the higher-level
classes this can be a bit heavy.
I noticed a problem with a model which required a single class from
osgSim. When osgdb_serializers_osgsim.so was loaded it registered
wrappers and created prototype objects for all of the osgSim classes,
including osgSim::ScalarBar. The constructor for that class creates
several drawables, and loads arial.ttf using the freetype plugin. I
don't need that, and don't even ship the font or plugin with my
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."

loading multiple VRML files in parallel. Christopher R. Baker has
detected this bug and crafted a patch. In addition, libcoin has to be
also built with the "--enable-threadsafe" option.
I copy here his report, extracted from
(https://bugs.launchpad.net/ubuntu/+source/openscenegraph/+bug/1211993)
and attach his fix. All credit is due to him:
«
There are three instances of a classical method-local-static
multithreaded initialization bug in the Inventor plugin for OSG that
trigger various memory faults when reading multiple VRML files in
parallel via osgDB::readNodeFile. These bugs are of the form:
static std::map<Stuff,OtherStuff> myHandyMap;
static bool once = true;
if(once) { ...fill myHandyMap; once = false }
... use myHandyMap;
To repeat: try loading multiple VRML files from multiple threads. The
liklihood of the bug depends on many factors, but my application, which
parallel-loads some dozens of small (<100K) VRML files on startup,
triggers this problem 25% of the time or more.
The attached patch (inventor-plugin-multithread.patch) rectifies this
problem by:
1 - Inheriting MyHandyMap from std::map, then
2 - Moving the map initialization into the derived constructor, which
3 - Is intrinsically protected from multithread issues by g++ (and is
part of the C++ standard), unless you pass -fno-threadsafe-statics,
which is strongly discouraged by the man page.

The delay between the 2 types of messages is more noticeable on Windows 8 and leads to serious disruptions in our application.
Mouse messages generated by touch input are only present for legacy support. I think they should be filtered out by OSG (real click events originating from a physical mouse will of course still go through).
This is what this patch does, according to this suggestion: http://msdn.microsoft.com/en-us/library/dd693088%28v=VS.85%29.aspx (third issue in this page)."

I found a bug on DDS ReaderWriter that generates a false positive on a guard for the size check on writing operation. This is due to a wrong imageSize computation that uses img->getImageSizeInBytes() method instead of img->getTotalSizeInBytes(), that actually ignores the r() dimension, contrariwise taken into account by the function ComputeImageSizeInBytes() later.
The line 1062 on file ReaderWriterDDS.cpp should be fixed with:
[code]unsigned int imageSize = img->getTotalSizeInBytes();[/code]

It doesn't check if the OpenGL renderer supports fbos. For indirect

the display server, which can lead to mipmapped textures failing to

But for glPrograms, in order to get all osg's uniform management system to work, I had to subclass osg::program::PerContextProgram.

osgViewer::Renderer doesn't use these enum settings so now no longer has a calls StateSet::clear() or StateSet::setGlobalDefaults() on the osg::Camera's StateSet. Previously these were being

"The idea of this new OpenGL feature is :
- set RestartIndex = "n"
- draw elements strip
-> when the index is "n", the strip is "stopped" and restarted
It's very usefull for drawing tiles with a single strip and a "restart" at the end of each row.
The idea a an OSG StateAttribute is :
Usually we use to build geometry from code, because software modelers rarely support it (and 3d file formats doesn't support it) :
-RootNode <= "PrimitiveRestartIndex=0" // So now, we know that our restart index is 0 for all drawables under this node
|
- Drawable 1 : triangles => as usual
|
- Drawable 2 : triangles strip => as usual
|
- Drawable 3 : triangles strip + "GL_PRIMITIVE_RESTART" mode = ON => use the restart index
|
- Drawable 4 : triangles strip + "GL_PRIMITIVE_RESTART" mode = ON => use the restart index
|
- Drawable 5 : triangles strip => as usual
With a StateAttribute, it's easy for the developper to say "0 will be my restart index for all this object" and then activate the mode only on some nodes.
The main problem is if you set and restart index value which is not included in the vertex array (for exemple set restart index = 100 but you have only 50 vertex). There is no problem with OpenGL, but some OSG algorithms will try to access the vertex[100] and will segfault.
To solve this, I think there is two ways :
1/ add restart index in osg::PrimitiveSet and use this value in all algorithms. It's a lot of work, maybe dangerous, and it concern only a few situations : developpers who use this extension should be aware of advanced OpenGL (and OSG) data management
2/ use a StateAttribute, and choose a "correct" restart index. In my applications, I always use "0" as a restart index and duplicate the first vertex (vertex[0] = vertex[1]). So there is no difference for OpenGL and all OSG algorithms works properly.
"
"The attached file contains:
- a per-context read counter in GLBufferObject::BufferEntry
- a global client counter in BufferData
- the glue between Texture* and Image client counter
"
I think this is necessary on OpenGL 3.2+ since this is no more "default" locations in the OpenGL specs.
The default behaviour stay the same.
There is a few new methods on osg::State :
- resetVertexAttributeAlias : reset all vertex alias to osg's default ones
- set**Alias : set a vertex attribute alias configuration
- setAttributeBindingList : set the attribute binding list (allow to specify an empty list if you're using "layout" qualifier in glsl code to specify the bindings. This save some CPU operations)"

// A custom class
namespace CustomDomain {
class MyGroup : public osg::Group

public:
META_Node( CustomDomain, MyGroup );
void setMyName( const std::string& n );

ADD_STRING_SERIALIZER( MyName, std::string() );
{
UPDATE_TO_VERSION_SCOPED( 1 ); // Updated for a new domain version
ADD_INT_SERIALIZER( MyID, 0 );
}
}
Save the class instance as follows:
osgDB::writeNodeFile( *myGroup, "serializer_test.osgt", new osgDB::Options("CustomDomains=MyDomain:1") );
The output file will include the domain version definition and all the class data, and can be read back. We can also force setting the domain version by the CustomDomains option while reading the saved files. If we save the class instance without any options, MyID will be ignored because the default domain version is 0.
This may help third-party libraries like osgEarth to maintain their own serializers without regarding to the OSG soversion changes.
Another feature added is a more robust binary format, which in fact adds a size-offset at each block's beginning. When there are problems or unsupported data types while reading, we can now directly jump to the block end indicated by the offset value. So a .osgb file will automatically ignore bad data and read remains as normal (at present it will fail at all). This feature will not break the backward compatibility, and can be disabled by setting "RobustBinaryFormat=false" while writing out.
Hope these changes can work smoothly with present and future community projects. Maybe we should also consider have an osgserializer example to test and demonstrate all things we can do now."
a few modifications to these files:
- applications/present3D/Cluster.cpp
- src/osgDB/FileUtils.cpp
The changes are needed to fix a few platform specific things such as the
absence of stat64, int/socklen_t differences, etc... and are in the same
line as Linux, Apple and FreeBSD specific checks.

This is because Qt auto repeats keyboard events, so multiple calls are made to GLWidget::keyPressEvent and GLWidget::keyReleaseEvent by Qt, and subsequently translated to OSG events.
The way to solve this is ignoring key released auto repeated events (see http://qt-project.org/doc/qt-4.8/qkeyevent.html#isAutoRepeat), so multiple KEYDOWN events are fired, but only one KEYUP.
I attach a modified osgQt/GraphicsWindowQt.cpp with this change."
New methods osg::Geometry::containsDeprecatedData() and osg::Geometry::fixDeprecatedData() provide a means for converting geometries that still use the array indices and BIND_PER_PRIMITIVE across to complient
versions.
Cleaned up the rest of the OSG where use of array indices and BIND_PER_PRIMITIVE were accessed or used.
It's
return osg::Image::computeImageSizeInBytes(width, height, depth, packing, slice_packing, image_packing);

GeometryNew is only temporary and will be renamed to Geometry on the completion of refactoring work and feedback from community.
Ported osggeometry across to use GeometryNew.
The API has changed quite a bit, so lots of changes had to be made in the osg readerwriter. The preious version of the FBX SDK (2013.3) already deprecated a lot of the names and functions. The code I submit now still compiles against 2013.3 (possibly needs a #define FBX_NEW_API). Not sure if that's useful, but it might ease the transition."

"
The following change to State.cpp fixes the case where textures in a stateset along with a compute shader program did not make those textures available to the shader, since it got evaluated before the texture bind(s)."
Note from Robert, Michael only change State::apply(StateSet*) so I also applied the same reversal in apply of texutre modes/state into the State::apply() method for consistency.
I looked into the "State::applyShaderComposition" method and noticed that it will print debug information to the osg::INFO stream. I commented that line out and the performance drop was gone.
I'm not sure if the printing was accidentally left in or is meant to be enabled. I've modified the function to only call the print function if INFO logging is enabled. I've attached the change."
- Added missing packing value on S3TC images. Images are coded with 4x4 blocs, whatever the image size. So there is an horizontal packing of 4 pixels (2 bytes in DXT1, 4 bytes in DXT2-5).
- Added crash guard against writing corrupted S3TC images.
Notes:
- What is missing is a support of "lines packing" in osg::Image (see code comments).
- S3TC-DXTC vertical flipping crashes (access violation) with some unusual dimensions (see code). I could not implement missing cases, so I added guards to avoid crashing."
Failure to perform a vertical flip on S3TC-DXTC now simply leaves the original image instead of corrupting it.
Image.cpp was sometimes performing a "normal" (= for uncompressed images) vertical flip on S3TC-DXTC images, producing weird results.
Actually, code was trying a "DXTC vertical flip" and relied on the result to call a "normal vertical flip". But when the "DXTC v-flip" encounters an error, this is is not necessarily because the image is not S3TC (ex: unhandled image dimensions)!
So now the code simply does "if dxtc, then flip_dxtc; else flip_normal;".
Note from Robert Osfield, moved the isDXT function into the dxt_tool file and namespace.
The solution for to refactor the way that events are checked so I add a bool return type to checkEvents() method across osgViewer::GraphcisWindow, osgGA::Devive and osgViewer::Viewer/CompositeViewer classes
Instead of
INCLUDE_DIRECTORIES(${LIBVNCCLIENT_INCLUDE_DIR})
the CMake variable

second email: "After a while I found that osg::Texture::applyTexParameters() used with TextureBuffer may cause some OpenGL errors ( applying texture filters and wraps to TextureBuffer makes no sense ) so I fixed it."
I hope the change seems reasonable. I searched the entire code base for code that accesses the StateSetStack, and noticed RenderBin and RenderStage use it. However, I don't think that code would ever be called from within the State::apply() function, so I'm fairly confident the change should be safe."

OSG_DEBUG << "Hello world!\n";
the underlying stream is not automatically flushed. It is flushed
if endl is queued instead of \n:
OSG_DEBUG << "Hello world!" << std::endl;
The notify macros do:
stream->setCurrentSeverity(severity);
return *stream;
So, if a function do:
OSG_DEBUG << "This is a debug message\n";
OSG_NOTICE << "This is a notice message" << std::endl;
the debug message will be classified as a notice message.
It is a problem when the application uses a NotifyHandler. The notify
method of the handler is called with:
severity = NOTICE
message = "This is a debug message\nThis is a notice message"
The attached Notify.cpp contains an automatic flush of the stream when
the current severity changes.

- user-value will be attached to Geode or Drawable
- has an option (named preserveNonOsgAttrsAsUserData) for control whether the UserValues should be attached (Default: no UserValues will be attached)

Header update
FindFFmpeg.cmake has been changed in order to support the new header include format for FFmpeg. In the 1.0 release, a new file had been added with the name “time.h” in the avutil library. The previous method of adding includes caused conflicts with the ANSI C “time.h” file. Now the include directive will only use the main include folder. All files using the old include format have been updated to reflect the change.
Added __STDC_CONSTANT_MACROS define to CMakeLists.txt
Since there is no guarantee that FFmpegHeaders.hpp will be included before stdint.h is included, the define has been moved from FFmpegHeaders.hpp to be part of the CMakeLists.txt for the FFmpeg plugin. This will allow the define to work on all compilers regardless of include order.
Replaced AVFormatParameters with AVDictionary
AVFormatParameters is no longer supported in FFmpeg and has been replaced with a key/value map of strings for each setting. FFmpegParameters and FFmpegDecoder has been updated to reflect this.
Replaced av_open_input_file with avformat_open_input
FFmpeg now opens files using avformat_open_input. Since the av_open_input_file method is deprecated, the FFmpegDecoder class has been updated to reflect this change.
Added custom AVIOContext field to options
Since some formats and inputs may not be supported by FFmpeg, I have added a new parameter that allows a user to allocate their own AVIOContext. This class will allow for creating a read, seek, and write callback if they desire.
Checking for start_time validity
It is possible for some file formats to not provide a start_time to FFmpeg. This would cause stuttering in the video since the clocks class would be incorrect.
Removed findVideoStream and findAudioStream
The new FFmpeg release already has a function that will find the best audio and video stream. The code has been replaced with this function.
Updated error reporting
Some functions would not log an error when opening a file or modifying a file failed. New logs have been added as well as a function to convert error numbers to their string descriptions.
decode_video has been replaced
The old decode_video function would remove extra data that some decoders use in order to properly decode a packet. Now av_codec_decode_video2 has replaced that function.
Picture format changed from RGBA32 to RGB24
Since most video will not contain an alpha channel, using a 24 bit texture will use less memory."

The impact of the bug was a memory leak that would affect multi-sampling iOS apps that allow for device rotation or window resizing in general. For our app, the leak ranged from ca. 10 MB to 40 MB per device rotation, depending on device, for the MSAA buffers. I have not been able to confirm impact for the stencil buffer. "
* ZeroConfDevice does now return FILE_NOT_HANDLED instead of FILE_NOT_FOUND
* present3D supports multiple devices per env-var P3D_DEVICE, separate multiple device with a space
I refactored parts the p3d-plugin, the curl-plugin and parts of Registry and ReaderWriter. Currently the p3d-plugin tries to open all remote files with the help of the curl-plugin.
I added a new method to Registry called getReaderWriterForProtocolAndExtension. which will return a ReaderWriter which is capable in handling the remote file for the given protocol and extension. If no readerwriter is found for the given extension, a list is built of all readerwriters supporting the given protocol and this list is checked for support of wildcards (extension = "*"). If anything matches it get returned.
I added this principle also to the Registry, so now it's possible to register a generic ReaderWriter which can handle all filetypes for a given protocol, similar what curl is doing. All you have to do is to load the plugin at startup. The curl-fallback is still in place.
With these changes it is now possible to reference a movie inside a presentation without a server-address, read the presentation (with curl) and stream the movie with the correct plugin (e.g. QTKit)

calculated model / view matrices up to that point. The IntersectionVisitor would instead keep the
view matrices calculated up to that point even though the Transform class will throw out the
calculated model matrix via “computeLocalToWorldMatrix.”
The change I made will push an identity matrix as the view matrix when running into a transform
with an absolute reference frame and will pop the matrix off after the traverse.
To test this, I created a camera with a perspective view and added a transform with some geometry
in it. Afterwards, I set the transform’s reference frame to ABSOLUTE_RF and spun the camera around

I fixed some bugs and did some more tests with both of the video-plugins. I integrated CoreVideo with osgPresentation, ImageStream has a new virtual method called createSuitableTexture which returns NULL for default implementations. Specialized implementations like the QTKit-plugin return a CoreVideo-texture. I refactored the code in SlideShowConstructor::createTexturedQuad to use a texture returned from ImageStream::createSuitableTexture.
I did not use osgDB::readObjectFile to get the texture-object, as a lot of image-related code in SlideShowConstructor had to be refactored to use a texture. My changes are minimal and should not break existing code.
There's one minor issue with CoreVideo in general: As the implementation is asynchronous, there might be no texture available, when first showing the video the first frame. I am a bit unsure how to tackle this problem, any input on this is appreciated.
Back to the AVFoundation-plugin: the current implementation does not support CoreVideo as the QTKit-plugin supports it. There's no way to get decoded frames from AVFoundation stored on the GPU, which is kind of sad. I added some support for CoreVideo to transfer decoded frames back to the GPU, but in my testings the performance was worse than using the normal approach using glTexSubImage. This is why I disabled CoreVideo for AVFoundation. You can still request a CoreVideoTexture via readObjectFile, though.

From Robert Osfield, removed the use of osg::Referenced and creating the proxy object on the heap.
--This line, and thosAttached is an update to ReaderWriterDAE.cpp/h and daeReader.cpp/h that implements
osgDB::ReaderWriter::ReadResult
ReaderWriterDAE::readNode (std::istream&, const osgDB::ReaderWriter::Options*)
This virtual function had never been implemented in ReaderWriterDAE. I implemented this function because the DAE plugin could not load files from other ReaderWriter derived objects that use protocol handlers.
I have updated function declarations in the header to have identical signatures with the base class declarations that include the default parameter.
readNode (std::istream&, …) is nearly identical to readNode(const std::string &, …) except it uses a new private function to convert the file from standard input:
bool daeReader::convert( std::istream& fin )
When this function is called fileURI is the string “from std::istream” to make the user aware where the file is coming from. Then instead of calling
_dae->open(fileURI)
we call
_dae->openFromMemory(fileURI, buffer.data())
Where buffer.data() is a pointer to the dae file text in memory.
Other changes include private functions to clear caches and to consolidate redundant code that appears between the two convert functions.

use in OpenGL.

The attached plugin can read:
* 1D, 2D, and 3D textures
* uncompressed and compressed images
* mipmapped and non-mipmapped textures
* little-endian and big-endian files
* textures from files as well as seekable istream objects
It does not handle:
* array textures (not supported by the ReaderWriter API)
* cubemap textures (not supported by the ReaderWriter API)
* the "KTXorientation" key-value pair; support could be added later (see
the file format spec for more information)
* non-seekable istream objects (would require more complicated memory
management)

What happens is this:
A view is created, and then the viewers thread is created and runs.
The setReleaseContextAtEndOfFrameHint is true.
To create a second view, the viewer is setDone(true), and we wait for the thread exit.
At this point, inside the ViewerBase::RenderingTraversals code, there are places where it reads "if(_done) return;"
The problem, is that it won't reach the code that will releaseContext().
Apparently, this driver won't let any other thread to makeCurrent(), if another thread (dead or not) has ownership. So when the Viewers is re-started, the first view won't be able to use the gc.
The change attached (against rev 13153) corrects this."
Attached are changes to GraphicsWindowIOS.mm to support setting up the new buffer type when compiling for iOS5,
also attached is a small change to FrameBufferObject.cpp to report support for packed depth stencil via the
GL_OES_packed_depth_stencil extension.
For anyone reading this you can attach a packed depth stencil to your FBO like so
_rttCamera->attach( osg::Camera::PACKED_DEPTH_STENCIL_BUFFER, GL_DEPTH24_STENCIL8_EXT );
Luckily GL_DEPTH24_STENCIL8_EXT happens to have the same value as iOSs GL_DEPTH24_STENCIL8_OES"
But the layers are not always children of the "model root" node : there can be a matrix transform between "model root" and "layers parent", so I've added the name "Layers" on the node which contains all layers to easily retrieve the layers groups from application code."
Cocoa and when to use the old Carbon interface for the windowing system.
The old code had to be modified for every new OS X release to default to Cocoa.
The new code uses Carbon for <= OS X 10.4 and Cocoa on everything else."
- Also, a 'dontSaveNormals' was added. It allows to ignore normals when writing an STL file. For example, it is useful for me when writing an STL file for CFD simulations.
- Some comments and code formatting were improved (to be consistent with the formatting already used in the plugin).
- With 'separateFiles' option files are now named fooX.stl instead of foo.stlX
The changes have been tested on various STL, both ASCII and binary found on the net. The change was based on the trunk branch."
From Robert Osfield, changed assert in Piotr's code to a runtime check warning report.
This fixes problems with PolygonZ records where the previous code was reading past the end of the record since it thought it had M values even if it didn't. I suspect the problem that James McGlone had back in 2006 was the same but reversed, when he tried to simply comment out the check, which was a (correctly) refused submission.""
and TabPlaneDragger.cpp:
TabPlaneDragger(float handleScaleFactor=20.0f);
The reason for this is that the default OSG tab sizes are way bigger than
those we used in our application so far. And since handleScaleFactor_
is already a (constant) class member, I see no objection against making
it user defined."
indexed draws instead of plain array draws to save some amount of main memory.
Draw performance does not change with the nvidia binary blob as well as with
the open source drivers."
