* avfoundation: added support for IOS (CoreVideo-support is still in development, works only for SDK >= 6.0, set IPHONE_SDKVER in cMake accordingly)
* zeroconf: added ZeroConf-device-plugin (Mac/Win only, linux implementation missing) to advertise and discover services via ZeroConf/Bonjour, on windows you'll need the Bonjour SDK from Apple
* osgosc: modified the example to demonstrate the usage of the ZeroConf-plugin (start the example with the command-line-argument --zeroconf)
* SlideShowConstructor: enable/disable CoreVideo via a environment variable (P3D_ENABLE_CORE_VIDEO)
* RestHttp: mouse-motion-events get interpolated
* RestHttp: unhandled http-requests get sent as an user-event to the event-queue, all arguments get attached as user-values to the event
* modified some CMakeModules to work correctly when compiling for IOS
* fixed a compile-error for IOS in GraphicsWindowIOS
* some minor bugfixes"
Added template readFile(..) function to make it more convinient to cast to a specific object type.
Added support for osgGA::Device to osgViewer.
Added sdl plugin to provides very basic joystick osgGA::Device integration.
(KTX). The KTX file format is straightforward and designed to be easy to
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)

(http://gta.nongnu.org). This allows to read and write floating point
image data. Unlike other formats, GTA also allows very good compression
ratios for floating point data. The compression method can be selected
with the COMPRESSION option of the plugin.

"- 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_GLES1_AVAILABLE=ON -DOSG_GL1_AVAILABLE=OFF
-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."
I have attached a patch, against the trunk from 13:30 today, which consists of the following:
1. CMakeModules/FindOpenEXR.cmake: Look for libIlmThread and libIex as well. 2. src/osgPlugins/CMakeList.txt: Only include the exr subdirectory if both the OpenEXR and zip libraries were found. 3. src/osgPlugins/exr/CMakeLists.txt: Add ZIP_LIBRARY to TARGET_EXTERNAL_LIBRARIES."
changed extensions from .c to .cpp and got compiling as C files as part of the osg core library.
Updated and cleaned up the rest of the OSG to use the new internal GLU.
synchronization, improve capture device support.
here how to use it to display a capture device:
osg::Options* options = new osg::Options;
options->setPluginStringData("captureWantedWidth", "800");
options->setPluginStringData("captureWantedHeight", "600");
options->setPluginStringData("captureWantedFps", "30");
options->setPluginStringData("captureVideoDevice", "USB Video Device" );
options->setPluginStringData("captureSoundDevice", "");
then
osgDB::readImageFile("capture.directshow", options)
you can use a graphedit application to list devices available in
directshow.
for classic avi file you just need to do a
osgDB::readImageFile("file.avi.directshow");
You will need of course to install the codec needed by directshow to
read the avi files.
I recommand this tool http://avicodec.duby.info/, that check which
video/sound codec is needed to play an avi file.
You can test it with the osgmovie example.

Converted Present3D across from using libxml2 to using the new osgDB::XmlNode/XmlNode::Input classes from Xml Parsing.
This changes removes the dependency on libxml2, and allows the present3D application and p3d to work on all platforms.
Also, there was also a small bug in osgDB's CMakeLists.txt that was causing an error when I tested with CMake 2.4.4.
IF(${OSG_DEFAULT_IMAGE_PLUGIN_FOR_OSX} STREQUAL "quicktime")
was changed to
IF(OSG_DEFAULT_IMAGE_PLUGIN_FOR_OSX STREQUAL "quicktime")

osgDB/FileUtils.cpp:
Needed this extra code to allow a true case-insensitive search. This is because the HL2 map and model files are often sloppy with case. For example, the file might look for materials/models/alyx/alyx_sheet.vtf, but the file is actually in materials/Models/Alyx/alyx_sheet.vtf. In case-insensitive mode, the new code recursively disassembles the path and checks each path element without regard to case. In case-sensitive mode, the code behaves exactly as it used to. The new code is also mostly skipped on Windows because of the case-insensitive file system. Previously, I did all of this with custom search code in the .bsp plugin, but this allows the user to tailor the search using OSGFILEPATH. There are some instructions in the plugins' README files about this.
osgPlugins/mdl:
This is a new plug-in for Half-Life 2 models (as opposed to maps). This allows you to load Source models individually, as well as allowing the .bsp plugin to load models (props) that are embedded into maps. Mdl files can contain simple object (crates, barrels, bottles), as well as fully articulated characters with skeletal animations. Currently, it can load the simple objects. It can also load the characters, but it can't load the skeletons or animations.
osgPlugins/bsp:
This contains all of the changes needed to load props along with the basic map geometry. There are also
several bugs fixed.
osgPlugins/vtf:
This is the loader for Valve's texture format. Previously, we had agreed to put this in with the bsp plugin, but I didn't think of the .mdl plugin at that time. It's conceivable that a user might want to load models individually (not as part of a map), so the vtf reader does have to be separate. I also fixed a rather significant bug.
I tested all of this code on RHEL 5.2 (32-bit), and Fedora 9 (64-bit). I'll be testing on Windows soon.
I also attached a simple .mdl file, along with it's associated files and textures. Just extract the tarball into it's own directory, set your OSGFILEPATH to point at that directory, and load the model like this:
osgviewer models/props_junk/gascan001a.mdl"
Source and CMake files are:
CMakeLists.txt
ReaderWriterBVH.cpp
Also there are 3 example BVH files. The first two are captured from motions of human beings - maybe a kung-fu master here. PLEASE use command below to see the results:
# osgviewer example1.bvh -O solids
This will demonstrate the animating of a skeleton and render bones as solid boxes. Note that the motion assumes XOZ is the ground and has an offset from the center, so we should adjust our view to get best effects.
You may also use "-O contours" to render bones as lines. The viewer shows nothing if without any options because osgAnimation::Bone does not render itself. User may add customized models to each named bones as osganimationskinning does to make uses of this plugin in their own applications.
I was wondering to support a BvhNode in my osgModeling peoject before, but soon found it better be a plugin for animation. A problem is, how to bind real geometry models to the skeleton. Maybe we could have a bindingToNode() visitor in future to find geodes matching names of bones and add them as bones' children."
The plug-in is a wrapper around open-exr (http://www.openexr.com) that consists of two projects, ilmbase-1.0.1 and openexr-1.6.1.
I have only tested it on windows XP 32 machine. So there might be some work making it work on other platforms.
The plug-in supports writing and reading EXR files. When writing it can use the data type GL_HALF_FLOAT_ARB(se ilmbase-1.0.1) and GL_FLOAT. When reading the data type always becomes GL_HALF_FLOAT_ARB. It supports textures with three and four channels.
When reading an exr file it automatically removes Alfa channel if it didn't store any information."

From Robert Osfield, started work on ported it to other platforms, but could fix some problems relating to error:
?Imf::OStream::OStream(const Imf::OStream&)? is private
I'm checking in now so that others can have a bash at completing the port.
The set up for this to work is a bit more complex than most files, since the engine expects all files to be in a certain place, and it tends to mix case a lot. I tried to explain everything in the VBSP_README.txt file."
This plugin has been integrated with the pre-exisiting bsp plugin.
