options->setPluginStringData("captureVideoDevice", "0");
Lines added in getDevice() are:
int deviceId = atoi(name.c_str());
if(deviceId >= 0 && deviceId < (int)_listDevice.size())
return _listDevice[deviceId];
This makes it easy to use a capture device without knowing it's name. Attached is the whole file against rev 11044"
osgAnimation. It's been tested with the majority of the samples in the
COLLADA test repository and works with all of them either as well as, or
better than, the version of the plugin currently in SVN.
Known issue: vertex animation (AKA morphing) doesn't work at present,
but that's a relatively unpopular method of animating so it's not high
on my priority list."

"I've been informed that the previous DAE submission didn't build on
unix, so here's the submission again with the fixes. Thanks to Gregory Potdevin and Benjamin Bozou.
Also, my apologies to Roland for not crediting his part in making DAE
animation happen, my work was indeed built on top of his work. Thanks
also to Marius Heise and of course Cedric Pinson."
Changes by Robert Osfield, fixed compile issues when compile without C* automatic conversion enabled in ref_ptr<>
and constructor initialization fixes to address some warnings under gcc.
png_set_expand_gray_1_2_4_to_8() with the 1.2.9 release. This
submission fixes builds of the OSG against versions of libpng < 1.2.9
that don't have the new symbol available. This affects platforms like
Red Hat Enterprise Linux 4 which come with libpng 1.2.7."
- Improved identifiers generation in duplicate name handling (was limited to 1000 name collisions, which can be very short for some usages).
- Set all read/write operations use a custom log function that will redirect lib3DS log to osg::notify() (was only used for streams)
- Removed custom code (now uses osgDB::getFilePath())
- Added missing supportsOption() calls
- Cleaned a few minor things"
modified files, while GroupSoLOD.h and .cpp was deleted. Please, delete
it from repository, it is not used any longer and I doubt if it is
probably not used for anything meaningful for a while. In the new code,
there is no GroupSoLOD. Please, delete it.
I am using new plugin version for about 1.5 month so I consider it
stable by myself.
List of changes:
- rewritten Inventor state stack
- shaders support
- light attenuation support
- support for reading from stream (readNode(std::istream& fin, options))
- improved grouping node handling (SoSeparator, SoGroup,...)
- fixed transformation bug when two SoShapes/Drawables with different transformations are placed bellow one grouping node
- introduced preprocessing to handle more advanced usage schemes of SoLOD and SoSwitch nodes
- unused code clean up
- improved notify messages
- animation callbacks fixes
- FindInventor.cmake improved finding routines, support for Coin3 and Coin4"
1. Rewrite the reading/writing exception handlers to work like the ive
plugin exceptions.
2. Write a header writing/checking function in ReaderWriterOSG2.cpp,
which may help decide if the stream is ascii or binary. The
readInputIterator() function will return null pointer if the input
file is nither osgb nor osgt format, which indicates that the old .osg
format could be used here, in case we've merged the two plugins
together.
3. Add a new ForceReadingImage option in the InputStream, which will
allocate an empty image object with the filename if specifed external
image file is missed. It may be useful for format converting in some
cases.
4. Add new osgParticle wrappers, as well as some modification to the
osgParticle headers, for instance, change isEnabled() to getEnabled().
5. Some fixes to the osg serialization wrappers."
Bone now inherit from MatrixTransform. It simplify a lot the update of
Bone matrix. It helps to have the bone system more generic. eg it's now
possible to have animation data with precomputed bind matrix. The other
benefit, is now the collada plugin will be able to use osgAnimation to
display skinned mesh. Michael Plating did a great work to improve this
aspect, he is working on the collada plugin and should be able to submit
a new version soon.
The RigGeometry has been refactored so now it works when you save and
reload RigGeometry because the source is not touched anymore. The
benefit with this update is that it should be now possible to use a
MorphGeometry as source for a RigGeometry.
The bad news is that the format has changed, so i have rebuild osg-data
related to osgAnimation data, updated the blender exporter to export to
the new format.
The fbx plugin could be touched about this commit, i dont compile it so
i can't give more information about it.
The bvh plugin has been updated by Wang rui so this one is fixed with
the new code of osgAnimation.
The examples has been updated to work with the new code too...
The example osg-data/example.osg should be remove, it's an old example
that does not work.
For people using blender the blender exporter up to date is here:
http://hg.plopbyte.net/osgexport2/
it will be merge to http://hg.plopbyte.net/osgexport/ as soon as the
modification will be push in the trunk.
"
From Robert Osfield, refactor of Wang Rui's original osg2 into 3 parts - parts placed into osgDB, the ReaderWriter placed into src/osg/Plugin/osg and wrappers into src/osgWrappers/serializers/osg
1) Add getShadowComparison() accessor function to osg::Texture class
2) Modify ReaderWriterTiff::writeTifStream() and _readColor() (in Image.cpp) to handle pixelFormat==GL_DEPTH_COMPONENT as if it were GL_LUMINANCE
3) Modify the Texture classes of the ive and osg plug-ins so that they save/load the following Texture members: _use_shadow_comparison, _shadow_compare_func and _shadow_texture_mode
"
- Fixed creation of useless intermediate nodes
WriterNodeVisitor.cpp fixes:
- Fixed naming of textures (path and extension)
"
Note from Robert Osfield, this submission also came with changes to use of ref_ptr<> and removal of delete[]'s, but these were not merged as they didn't actually fix any memory leaks, and in once instance introduced one.
In particular, the case when the "instance_geometry" element has no "bind_material" sub-element. This is valid, according to the official collada 1.4.1 specification."
> loader to un-premultiply the alpha (now in the codebase).
Applying the code brightens the semi-transparent portion, but the black edges are still there (same on both osgviewer and FlightGear).
Therefore I believe that the alpha channel is completely ignored (on png, gif, tiff, etc...). I tweaked and tweaked and finally got a workaround.
Please commit the enclosed file to fix these issues.
My workaround is a bit tricky (and some lines are even weird for me), but it resolves the black edges.
These workarounds also work on GIF, TIFF, TGA, and PSD as long as I've tested so far.
Please read this for more info on this issue:
http://macflightgear.sourceforge.net/home/development-notes/devnote-dec-02-2009http://macflightgear.sourceforge.net/home/development-notes/devnote-dec-03-2009
I'm very happy if some of you guys find a better means of solving the black edges.

"Here is our freshly baked 3DS reader/writer (named 'v0.5' to differentiate from previous one). Changes are against trunk rev. 10819.
Short changelog (from rev 10819):
- Added 3DS writer
- Sync'd with latest lib3DS
- Added options, especially "flattenMatrixTransforms" to get the "old" behaviour (else the reader correctly maps to OSG the transforms from the 3DS file).
What should be done:
- Check with pivot points, with and without "flattenMatrixTransforms" option.
- We ran tests on it, but we can never be 100% sure there is no bug. Testing from the community would of course be helpful."
fixed a small bug then:
ReaderWriterPDF.cpp, line 133, change:
std::string uri = std::string("file:") + foundFile;
to:
#if defined(WIN32) && !defined(__CYGWIN__)
std::string uri = std::string("file:///") + foundFile;
#else
std::string uri = std::string("file:") + foundFile;
#endif
That's because glib accepts "file:///C:\\data\\file.pdf" as URIs on
Windows, as well as "file:/home/data/file.pdf" on Unix, but
"file:C:\\data\\file.pdf" is not recognized.
Now I could read my Chinese translation of OSGQSG with osgpdf. :P"
and so, if the .dot plugin was loaded, it would happily handle any file
name extension.
To reproduce the bug, first save a scene to a dot file (to load the dot
plugin), then try to write the scene to an osg file. If you look at the
osg file, you will see that it is a dot file."
.dds texture files from internally-embedded textures during IVE writes."
From Robert Osfield, fixed a bug in the above submission, and changed the way that the filename of the file is passed into DataOutputStream to avoid issues with the .ive's plugins ability to read from istreams.
functionality and I also modified osgmovie example to support "seek"."
Note from Robert Osfield, changes osgmovie to use '>' for the seek as '+' was already used in a separate submission that had been merged.
then reload a video and finally delete the second XineStreamImage.
In src/osgPlugins/xine/video_out_rgb.c, many code is ASM code, and 'clear()' function is one of them.
If OSG is compiled without the flag COMPILE_ASSEMBLY (default behaviours) the clear() function is an empty
function and allocated memory is never initialized to 0. So a structure which contain pointer haven't its pointer set to NULL.
And when we need to delete this pointer, all go bad.
I join the fixed file."
being able to accurately provide the cool stuff that SVG is good for. :)
There is a one-line bug on line 68 in the
src/osgPlugins/svg/ReaderWriterSVG.cpp file where you can set the width
in the Options string, but not the height."
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.

The patched loader also complains more loudly if a material library file wasn't found or if a referenced material wasn't found in the material library."
makes smoothing optional for verticies which do not have a normal
associated with them in the OBJ input file. The previous behavior was
to always smooth at all verticies which did not have surface normals.
In this new implementation smoothing is on by default to be compatible
with previous behavior. The user can now specify the "generateFacetNormals"
option to the reader to use facet normals for verticies where the OBJ
file does not specify a normal."
Note from Robert Osfield, changed "noSmoothing" naming used by Lee to "generateFacetNormals".
Most notable the __hpux define stuff. The __hpux__ variant seems to be not
defined which resulted in a compile error at this time. Consequently I have
replaced all occurances of __hpux__ with __hpux. And huge surprise: now osg
plugins are found and loaded correctly ...
The next notable one is the MSVC_IDE fix which makes the nmake Makefiles cmake
generator target behave like the ide one. Showed up because I started to do
scripted builds with nmake instead of devenv...
The rest is the usual bunch of stuff that just happens during normal
coding ..."
I attach a modified ReaderWriterZIP.cpp (based on version 2.9.5 revision 10374).
This includes a little bit of code tidying, but the only functional change is a test of the return value of OpenZip and the addition of a call to CloseZip."
It adds new PrimitiveSet constants for the specific geometry shader primitive types :
- LINES_ADJACENCY
- LINE_STRIP_ADJACENCY
- TRIANGLES_ADJACENCY
- TRIANGLE_STRIP_ADJACENCY
It also adds some missing features to the glsl reader plug'in.
