The pvr format which can be used as a wrapper for different compressed and uncompressed formats supports this compression algorithm. The original pvr compression uses the pvrtc format. The handling of pvrtc is already implemented in the pvr plugin. PVR provides wrapper functionality for some formats, e.g. etc or even dxt/dds.
Our target system (gles2) is able to use the etc compression format. With minor changes in the submitted files, there is no need to write a separate plugin. However the original pvr texture compression formats are not supported on our target, which is the reason for this extension.
The changes mainly consist in the definition on new enum values in the classes and headers of ReaderWriterPVR,Image and Texture. I also found some locations where the handling of the original pvr textures was not implemented. These are also part of this submission."
I also fixed the vsync implementation introduced with rev.11357 that was crashing with the Windows Error #170. So I removed your temporary /* */ around the vsync condition..."
2nd - Script to use a 3rd party directory with basic libraries: libjpeg,libpng,libtiff,giflib,freetype,curl,gdal.
3rd - Change in the GLES library loading for Android. That should make GLES2 work properly.
4rth- Included two defines RGB8_OES and RGBA8_OES as a substitute in GLES for RGB8 and RGBA8
5th - OpenGL and GLSL version identification changed to recognize GLES versions properly

The main motivation for this is to easily allow the user to specifiy that the device is in a horizontal orientation rather then having to rotate the view matrix. All flags have been tested individually as well as in combinations. The default is ALL_ORIENTATIONS to keep the exiting functionality for anyone who hasn't specified WindowData for their context traits.

external applications can determine if an archive extension is valid.
The second change is a bug fix in Registry::read(const ReadFunctor&)
where if you pass in valid options they get wiped out after the archive
is loaded but before being passed along to the plugin."
that the windows did not act on repaint request (WM_PAINT, EXPOSE,...)
Detailed explanation:
- I implemented requestRedraw using the push approach (not using
GraphicsWindow::_requestRedraw flag that I was considering) as there may be
multiple viewers reading the flag and fighting to reset it after the paint
request, while some viewers may not spot the request to redraw
- I made windows call GraphicsWindow::requestRedraw when they receive
appropriate message (WM_PAINT, EXPOSE, RESIZE,...)
- There were issues on Linux that windows did not want to close using x
button. Resolved by moving the test for DeleteWindow event from
swapBuffersImplementation() to GraphicsWindowX11::checkEvents(). The difficulty
was that DeleteWindow event is not coming using _eventDisplay, but through
_display.
- The last difficulty was that it is necessary to call
ViewerBase::checkWindowStatus() to set _done to true when all windows are
closed. This did not happened recently in ON_DEMAND run scheme. I put the call
to checkWindowStatus() to eventTraversal.

Clean up of visitor naming to make it clearer what role it has.
One can override this value via the sampleDensityWhenMoving="value" property in the volume tag, i.e.

To switch the feature off set the value to 0, i.e.

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).

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.

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.

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.

This file adds the same string API wrapper to the State object for other older apps that
track Uniforms by string. The original comment about performance is preserved."
are big enough to handle the primitives used in the geometry.
Added usage of verifyArray into osgfilecache so that it reports any problems on reading files in paged database.
* the glsl plugin now supports processing #includes. The file extension sets the shader type.
* the registry releases gl objects of the shared state manager
"
I see that we should expect some performance penalty for using this method. It won’t be painful in my current case because I have only a few animated characters. But I suspect some day I will have to fix osgCal to use int UniformIds natively for larger crowds."
hpux. I have skipped irix this time as irix is too dead to keep osg building
there.
As usual, solaris does not like member templates in stl containers.
Some headers missing and link problems due to missing libraries."
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."
attached you'll find the second part of the IOS-submission. It contains
* GraphicsWindowIOS, which supports external and "retina" displays,
multisample-buffers (for IOS > 4.0) and multi-touch-events
* 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."
Notes, from Robert Osfield, modified CMakeLists.txt files so that the IOS specific paths are within IF(APPLE) blocks.
* support for NPOT-textures on IOS
* support for FBOs (only renderToTexture for now) on IOS (should work
for other OpenGL ES 1/2 targets, too)
* FileUtils-support for IOS"
