supportsOption("dds_dxt1_rgba","set the pixel format of DXT1 encoded images to be RGBA");

And set the default not to modify and detect the RGB or RGBA pixel format for DXT images.
One can override this value via the sampleDensityWhenMoving="value" property in the volume tag, i.e.
<volume sampleDensityWhenMoving="0.01">CardiacCT</volume>
To switch the feature off set the value to 0, i.e.
<volume sampleDensityWhenMoving="0">CardiacCT</volume>
2. Removed unecessary code. Also made sure the images names are not truncated in the middle of an UTF8 character. You'll find there a function called utf8TruncateBytes(), which may be moved in core OSG (osgDB/ConvertUTF I guess). Feel free to do it if you feel it that way.

1. daeRGeometry.cpp (rev 12132). A tiny sumbission which fixes a quite important bug: a parameter was forgotten in Collada ReaderWriter, and texture coordinates could not be loaded properly. So:
"
Added missing paramter when calling createGeometryData(). Fixes missing texture coordinates (in "bind_vertex_input").
"
2. ReaderWriterDAE.cpp (rev 12132):
"
Added "baseImageDir" as a plugin string data, in order to manually specify base directory to use when relativising image file names. This is used to properly write files, when images are not located in a subdirectory (like "../images" for some software).
"
1. DAE submission:
DAE plugin now correctly writes images URI in Collada file, when images are used twice.
I also greatly improved readability and maintenability of geometry reading (mainly daeRGeometry.cpp), by factorizing code, templatizing it (for double/single precision), and removing ugly macros.
2. osgDB submission:
I updated osgDB::getPathRelative(): it is now far more readable, it handles more cases (especially when you want to relativise "a/c" from "a/b", which results in "../c"), and I added comments to make it clearer to maintain."
DAE plugin was linking ORIGINAL images in the Collada file, using image->getName() as a path (even if images were modified in memory!). As the behaviour was not the one of other plugins (3DS, FBX, and such), I made the plugin relativise images filenames (as those plugins) and write the image which is in memory. However, in order to avoid removing features, I kept the previous behaviour but moved it in an option. Here are the options of the plugin I changed:
- daeForceTexture was unclear in this new context and removed in favor of two new options
- daeLinkOriginalTexturesNoForce: Writes reference to the original image if found, instead of writing the image in memory
- daeLinkOriginalTexturesForce: Writes reference to the original image even if not found, instead of writing the image in memory
Of course, if you specify no option, images are written as for other plugins.
Other thing I changed is the UTF8 support as I told you in a previous conversation. Now there is a simple option, "daeNamesUseCodepage", which makes all names except filenames (materials, animation, geometries...) be considered as encoded using current codepage. If so, they'll be converted to UTF8 when writing; else they are written directly. Of course, filenames follow OSG_USE_UTF8_FILENAME as usual.
I did "
1. It did not support normals applied to individual vertices.
2. It would only support red / green / blue colour triples, but the pmvs models are generated with diffuse colours. (The PLY format, http://local.wasp.uwa.edu.au/~pbourke/dataformats/ply/, lists specular and ambient colour forms as well.)
To partially overcome these limitations, please find attached modified versions of
src/osgPlugins/ply/vertexData.cpp
src/osgPlugins/ply/vertexData.h
The changes I've made are:
1. I have changed the boolean hasColor flag to a vertexField (which is a boolean operation on an enum) to indicate what fields are present in the ply file. (This is required because Turk's ply reader spits out warnings for every line where you try to read fields which do not exist.)
2. I have modified the code to apply valid normals to either triangles or vertices.
3. I have kludged in "support" for the various colour variants. Specifically, all the colour specified can be read from the file. However, they are all applied in the same way (namely as a colour array, bound to each vertex)."
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."
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.
We should have:
UV for vertex 0, layer 1
UV for vertex 0, layer 2
UV for vertex 1, layer 1
UV for vertex 1, layer 2
...etc...
Instead, we have this:
UV for vertex 0, layer 1
UV for vertex 1, layer 1
...etc...
UV for vertex 0, layer 2
UV for vertex 1, layer 2

requests to a removed archive file. ReaderWriterTXP::getArchiveName
will create an archive if it doesn't exist. This is causing a crash
if the terrain is removed and there are outstanding database requests
in the database pager. The request will create a new archive, and as
the archive is newly create doesn't have the materials etc to support
the subtile that was just loaded. To fix the problem getArchiveName
will only return existing archives. createArchiveName was added to
create archives.

It's possible we have other code like that in other plugins, I guess
it's a side effect of the MACRO stuff about notification."

recently we noticed a little mistake for 3DS files using instances of the same meshs: Every groupnode gets the same name instead of the (correct) instance name of the object. The fix only consists of two additional lines which check whether an instance_name is given for the object and then uses this one instead of the node name."
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.

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."
ReadDDSFile warning: couldn't read mipmapData
The issue is caused, when the last block of data is read from the file (less than chunk size of 16384 bytes). The read operation in ReaderWriterGZ::read() then sets the eof and fail bit in the stream and the lines

osgWidget::Input:
[Functional changes]
- Previously, the field would be filled with spaces up to its max length, and typing would just replace the spaces. Also, there was a _textLength variable that kept track of the real length of text in the field, since the osgText::Text's length just reflected the length of spaces+text entered. This was not great, as you could still select the spaces with the mouse and it just feels hacky. So I changed it to only contain the text entered, no spaces, and _textLength was removed since it's now redundant (the osgText::Text's length is used instead).
- Fixed the selection size which (visually only) showed one more character selected than what was really selected.
- Fixed selection by dragging the mouse, it would sometimes not select the last character of the string.
- Cursor will now accurately reflect whether insert mode is activated (block cursor) or we're in normal mode (line cursor) like in most editors.
- Implemented Ctrl-X (cut)
- Added a new clear() method that allows the field to be emptied correctly. Useful for a command line interface, for example (hint, hint).
- Mouse and keyboard event handler methods would always return false, which meant selecting with the mouse would also rotate the trackball, and typing an 's' would turn on stats.
[Code cleanup]
- Renamed the (local) _selectionMin and _selectionMax variables which are used in a lot of places, as the underscores would lead to think they were members. Either I called them selection{Min|Max} or delete{Min|Max} where it made more sense.
- Fixed some indenting which was at 3 spaces (inconsistently), I'm sure I didn't catch all the lines where this was the case though.
- Put spaces between variable, operator and value where missing, especially in for()s. Again I only did this where I made changes, there are probably others left.
The result is that delete, backspace, Ctrl-X, Ctrl-C, Ctrl-V, and typing behaviour should now be consistent with text editor conventions, whether insert mode is enabled or not. I hope. :-)
Note, there's a nasty const_cast in there. Why isn't osgText::Font::getGlyph() declared const?
Also, as a note, the current implementation of cut, copy and paste (in addition to being Windows only, yuck) gets and puts the data into an std::string, thus if the osgText::String in the field contains unicode characters I think it won't work correctly. Perhaps someone could implement a proper clipboard class that would be cross-platform and support osgText::String (more precisely other languages like Chinese) correctly? Cut, copy and paste are not critical to what I'm doing so I won't invest the time to do that, but I just thought I'd mention it.

crash with some files.
Actually, itr was incremented into the loop and after the test with
nlist.end().
Then, the unreferencing of itr when nlist is equals to nlist.end() caused
the crash."
The current version crashes when encountering global materials, as also reported in the forum by the author of the plugin.
The problem in mesh.cpp (app. ln 247) is, that references to global materials that are given in curly brackets {} are not supported by the reader. However, curly brackets seem to be common, according to Bourke. Unfortunately, I found no specification. However, also the DirectX model viewer that comes with the DirectX-SDK (August 2009) expects curly brackets and refuses models without them.
My fix checks 2 more cases ("{ aMaterial }" -> 3 tokens and "{aMaterial}" -> 1 token), and extracts the material name for the lookup. I don't know if this is the most elegant solution, but the tokenizer seems to split based on white spaces.
You can reproduce the bug with the attached model (box.x), which loads fine in other tools, such as 3DSmax, DeepExploration or the DirectX model viewer. When I remove the curly brackets at the reference of "myGlobalMaterial", it loads in osgviewer, but is not standard conform.

Out application has the ability to switch to different types of terrains on the fly. This problem only exists in this type of situation.
The TXPArchive is held by the ReadWriterTXP class. When the TXPNode, which is the top level node, is released from memory, the archive associated to that TXPNode is also released. The issue is that the reference count on the TXPArchive never gets to zero.
The reason why the reference count never gets to zero is because the TXPParse, which is owned by the TXPArchive, stores a ref_ptr to the TXPArchive. You can then see why this becomes a problem. The TXPParser's ref_ptr cannot be unreferenced since the TXPArchive has not released the TXPParser.
Since the TXPParser is fully contained within the TXPArchive, I don't see the reason to have the TXPParser have a ref_ptr to the TXPArchive. I've made this change locally and have had no problems and our memory leak has been fixed.

I've added a new option "SchemaData" to the osg2 plugin. Developers

# osgconv cow.osg cow.osgb -O SchemaData
It will record all serializer properties used in the scene graph, at
the beginning of the generated file. And when osgviewer and user
applications is going to read the osgb file, the inbuilt data will be
automatically read and applied first, to keep backwards compatibility
partly. This will not affect osgb files generated with older versions.

With these modifications it is possible to compile frameworks on OS X,
when you set the Cmake-option OSG_COMPILE_FRAMEWORKS to true. If you
want to embed the frameworks in your app-bundle make sure to set
OSG_COMPILE_FRAMEWORKS_INSTALL_NAME_DIR accordingly.
You'll have to build the install-target of the generated xcode-projects
as this sets the install_name_dirs of the frameworks and plugins."
few headers and the osgAnimation sources are also modified to make
everything goes well, including:
A new REGISTER_OBJECT_WRAPPER2 macro to wrap classes like
Skeleton::UpdateSkeleton.
A bug fix in the Seralizer header which avoids setting default values
to objects.
Naming style fixes in osgAnimation headers and sources, also in the
deprecated dotosg wrappers.
A bug fix for the XML support, to write char values correctly.
A small change in the osg::Geometry wrapper to ignore the
InternalGeometry property, which is used by the MorphGeometry and
should not be set by user applications.
The avatar.osg, nathan.osg and robot.osg data files all work fine with
serializers, with some 'unsupported wrapper' warnings when converting.
I'm thinking of removing these warnings by disabling related property
serializers (ComputeBoundingBoxCallback and Drawable::UpdateCallback),
which are seldom recorded by users.
By the way, I still wonder how would we handle the C4121 problem,

a byte order issue.
The problem is that osg::SwapBytes code has been copied from the old
plugin to the new one, but the latest lib3ds also incorporates code to
handle byte ordering in read & writing. So the net result is that the
swap is done twice.
The solution is simply to remove the custom osg code, and use the
stock lib3ds code. The attached files are against today's revision
11331. I've tested on Sparc & Intel.
"
- Fixed handling of MatrixTransforms (still doesn't support other Transforms types). Fixes things for OSG, DeepExploration, 3DSMax...

- Replaced exceptions with assert() or OSG_NOTIFY
- Replaced osg::notify() with OSG_NOTIFY

- Cleaned a few things in code (names, added deallocations upon error)"
And by refactoring a bit of code, I may have fixed some StateSets related bugs (was ignoring StateSets for osg::Groups).
I also added support for Billboard's points, so now "osgconv lz.osg lz.3ds" has an acceptable output. However, there is no rotation depending on billboards' axis, hence the notice "Warning: 3DS writer is incomplete for Billboards (rotation not implemented).". You may want to remove this notice (or lower the notify severity) if you feel 3DS doesn't have to handle such rotations.
The attached archive contains 3 files from 3DS plugin, against rev. 11162.
Please note there is still the textures issue for cow.osg. I guess it's because it's not a "flat, dummy and standard" texture in slot 0... That is to say the only thing the writer can handle at the moment. I guess I won't address this soon.

Attached you will find updates of the files to hopefully solve the warnings (in VS2005 only one warning occured). In addition I fixed a tiny bug that caused a crash with one of my test files."
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."
