serializers and dotosgwrappers. It includes reading/writing supports
for the two new shader types and the GL_PATCHES enum. The
setParameterfv() method is not wrapped at present because it is still
not finished.
Enum serialziers don't require back-compatibility checks if only
add/remove enum items, so I'm not going to use the new
UPDATE_TO_VERSION macro this time."
2: minor tweak for a DebugHUD drawn improperly case when multiple slave views shared one window. It now uses slave view viewport to correctly position DebugHUD.
3: deactivated ConvexPolyhedron notifications (they were accidentaly activated when you replaced osg::notify calls with OSG_NOTIFY macro). These warnings are useful only for shadow map developer working on shadow volume optimizations. So there is no sense in having them active all the time."
Problem 1 :
With GLSL, multi pass to apply each shadow map is not required.
Problem 2 :
GLSL code use "shadow2DProj" build-in function to look up in shadow texture.
Projection is orthogonal so "shadow2D" build-in function is sufficient.
Problem 3:
Bad calcul in
osgShadow::ParallelSplitShadowMap::calculateLightViewProjectionFormFrustum(..)
provide some visual error in specific configuration.
to reproduce pssm_bug.jpg, you need to add a light direction in osgshadow.cpp example (done in joint osgshadow.cpp file)
then "osgshadow --noUpdate --pssm --maxFarDist 500 --minNearSplit 500 --mapcount 6 --debug-color model_test.3ds"
As you can see in pssm_bug.jpg and pssm_fix.jpg, performance is really better when Problem 1 is fixed.

osgGA. My approach is to bundle all touchpoints into one custom data
structure which is attached to an GUIEventAdapter.
The current approach simulates a moving mouse for the first touch-point,
so basic manipulators do work, sort of.
I created a MultiTouchTrackballManipulator-class, one touch-point does
rotate the view, two touch-points pan and zoom the view as known from
the iphone or other similar multi-touch-devices. A double-tap (similar
to a double-click) resets the manipulator to its home-position.
The multi-touch-trackball-implementation is not the best, see it as a
first starting point. (there's a demo-video at http://vimeo.com/15017377 )"
serialization libraries. My submission mainly includes:
1. Add two new macros USE_DOTOSGWRAPPER_LIBRARY and
USE_SERIALIZER_WRAPPER_LIBRARY. Applications using static OSG must
include corresponding static-link libraries and use these two macros
to predefine native format wrappers. Please see osgstaticviewer and
present3D in the attachment for details.
2. Add a LibraryWrapper.cpp file in each
osgWrappers/deprecated-dotosg/... and osgWrappers/serializers/...
subfolder, which calls all USE_...WRAPPERS macros inside. The
LibraryWrapper file is automatically generated by the
wrapper_includer.cpp (with some slight fixes), which is also attached
for your reference. The deprecated-dotosg/osgAnimation is not included
because it doesn't us REGISTER_DOTOSGWRAPPER to define its wrappers.
3. Modify the ReaderWriterOSG.cpp to prevent calling loadWrappers()
when static build.
4. An uncorrelated fix to Serializer and ObjectWrapper.cpp, which
ensures version variables of serialziers are initialized, and
serializers out-of-version are not written to model files.

templated constructor of std::pair not being able to automatically
convert 0 to a pointer. Rather than use preprocessor checks and
#defines, I think a cleaner solution is to cast the std::pair arguments
to the appropriate types to help the compiler out. I attached an updated
version of the file implementing this."
Initial email from Tim : "I've implemented using a timestamp, available with ARB_timer_query and OpenGL 3.3, to gather GPU stats. This is nice because it can accurately fix the GPU draw time with respect to the other times on the stats graph, rather than having to estimate the wall time of the end of GPU drawing. This also prevents anomalies like the GPU phase starting before the draw phase..."
Changes to Tim's submission by Robert: Removal of need for swap buffer callback in ViewerBase.cpp, by
integrating a osg::State::frameCompleted() method that does the stats timing collection. Introduction of a
GraphicsContext::swapBuffersCallbackOrImplementation() method that calls the State::frameCompleted() and
the swap buffers callback or the swapImplementation as required.
present3D application. As static-link present3d should depend on
freetype, png, pdf and some other plugins, any mis-compiling of these
plugins will make present3d fail to be built. Some lirbaries like
poppler and cairo are not popular under Windows, so it is very common
that we don't have osgdb_pdf compiled and thus get errors when
building present3d. I've modified the CMakeLists and present3d.cpp to
avoid this problem."
But I also found rev. 11354 (from Wang Rui) added a change in OsgMacroUtils which adresses a similar issue: Wang told the "../../bin" prefix wasn't working. However I think the fix isn't correct because it checks the MSVC version instead of the CMake version. Here is my fix, against latest trunk (root CMakeLists.txt, and CMakeModules/OsgMacroUtils.cmake).
Tests I made:
| Unix Makefiles | MSVC 9 | MSVC 10 x64
---------------------------------------------------
CMake 2.4 | | OK | N/A
CMake 2.6.4 | | OK | N/A
CMake 2.8.0 | | OK | broken support?
CMake 2.8.2 | | OK | OK

functionalities. It includes two main parts: a version checking macro
for handling backward-compatiblity since 3.0, and enhencement of
current schema mechanism. I also change the option handling process to
use getPluginStringData(), and add new USE_SERIALIZER_WRAPPER macro in
the Registry header to allow for static-link usage as well.
The enhencement of schema machanism just tells the type of each
serializer while outputting them, such as:
osg::Group = Children:1
The meaning of the number can be found in the osgDB/Serializer header,
BaseSerializer::Type enum. It may help 3rdparty utilities understand
the structure of the wrapper and do some reflection work in the
future.
The new macro UPDATE_TO_VERSION can help indicate the InputStream (no
affect on the writer) that a serializer is added/removed since certain
OSG version. An example wrapper file is also attached. The
Geode_modified.cpp is based on the serializers/osg/Geode.cpp file
(hey, don't merge it :-), but assumes that a new user serializer
'Test' is added since version 65 (that is, the OSG_SOVERSION):
REGISTER_OBJECT_WRAPPER( Geode, ... )
{
ADD_USER_SERIALIZER( Drawables ); // origin ones
UPDATE_TO_VERSION( 65 )
{
ADD_USER_SERIALIZER( Test ); // a serializer added from version 65
}
}
All kinds of ADD_... macros following UPDATE_TO_VERSION will
automatically apply the updated version. The braces here are only for
typesetting!
While reading an osgt/osgb/osgx file, OSG will now check if the file
version (recorded as the writer's soversion, instead of previous
meaningless "#Version 2") is equal or greater than Test's version, and
try reading it, or just ignore it if file version is lesser.
And we also have the REMOVE_SERIALIZER macro will mark a named
serializer as removed in some version, with which all files generated
by further versions will just ignore it:
UPDATE_TO_VERSION( 70 )
{
REMOVE_SERIALIZER( Test );
}
This means that from version 70, the serializer Test is removed (but
not actually erased from the list) and should not be read anymore. If
the read file version is less than 70 (and equal or greater than 65),
Test will still be handled when reading; otherwise it will be ignored
to keep compatiblity on different OSG versions.
"
As it works (for our needs at least) I've done and attached a tar.gz file for the VRML2 plugin with a new part to write a VRML2 file from an osg one.
The read part is the same as in osg 2.9.9.
The write part code is in convertToVRML.cpp and .h files. It works for some osg nodes (group, geode, matrixTransform, positionAttitudeTransform and geometry). Textures are converted to jpeg (if not translucent) or png (if translucent).
There are some options that could be given to the writer (with -O switch) :
convertTextures=0 to copy textures without converting them to jpeg or png
convertTextures=-1 do not copy textures, keep them in their original format and location
convertTextures=-2 do not use textures, parse only geometry
convertTextures=-3 (default) convert textures to jpeg or png ones.
textureUnit=X in case of multiple textures, X= texture unit to use (default value=0)
directoryTexture=aPath when texture will be copied, it will be in this directory, not in the current one."
