Re: [osg-users] osgconv
Hi Ekaterina, how is your OSG_NOTIFY_LEVEL set?

Loading and playing single FBX files seems to work fine. My problems begins when I try to copy animations from several FBX files into one model.

I start by loading the first model, locating the AnimationManager, then opening the rest of the models. For each model I am locating their AnimationManager and getting the animation stored inside it, then coping and registering the animation into the first file's AnimationManager.

The bone responsible for the characters arm gets connected to the geometry of a foot and some of my animated characters literally ends up with their head up their own arse.

Re: [osg-users] Display Order with OpenGL ES 2.0 on Android
Hi Bruno,
you probably want the behind quad to have a different depth (second
value in the osg::Vec3), so it will appear to be behind the other quad.
The order in the graph or the order of adding to the graph has no impact
on the result at all.

Hi Robert, we noticed over here that something goes wrong if the viewer is started with OSG_STEREO=ON, both with anaglyph stereo on windows and with Quad buffered stereo on linux. We don't have a fix yet, and probably won't get around to digging out the actual problem this week, so for now only a bug report. steering with the mouse is impossible, which I traced back to osgGA::GUIEventAdapter::getXnormalized() (and Y) returning values way larger than 1. (about 1024 or so) we suspect this is caused in some way by assignStereoOrKeystoneToCamera not calling assignKeystoneDistortionCamera at all if redering is stereo and no keystone file is set.

Hi Gabriel, First a question: what operating system are you using? Second question: when your shared library gets unloaded, do any other shared library's get unloaded as well? On windows I can imagines your dll being linked to an osg part that will install callbacks in the scengraph, (osgAnimation.dll as a possible example), while your main application has no such link. On unloading the dependencies can be unloaded as well, causing the callback to call an invalid memory location. Regards, Laurens.

Re: [osg-users] wglGetCurrentContext vs osg::GraphicsContext::createGraphicsContext
Hi Anders,
did you try:
m_viewer-setReleaseContextAtEndOfFrameHint(false);
before the call to
m_viewer-frame();
Hope that helps,

Re: [osg-users] Lock the aspect ratio while allowing the window to be resized
Hi Ethan, I did not understand your question correctly. Setting the camera to camera-setProjectionResizePolicy(osg::Camera::FIXED) will fix the projection, not the window. As the version you want is not implemented in osg, you will need to catch resize attempts and force the window to resize while preserving the aspect ratio. the osgviewer application has a viewer.addEventHandler(new osgViewer::WindowSizeHandler); You probably should replace that with a new handler, allowing only to resize with fixed aspect ratio. Laurens.

Hi All,
I have ffmpeg movie audio working with osgAudio, but have been to busy to
clean up the code, create an example and submit for inclusion in the
osgAudio library. To avoid duplicate work I attach my current code as is.
Currently this is working part of our program, running both on linux

never tested.
attached is a zipfile with AudioSink.h
example should be a variation on osgMovie, but should be in the osgAudio
library, because osgAudio depends on osg.
Laurens.

You need to extend osg::AudioSink with the osgAudio code that you have

Re: [osg-users] Frame syncing over multiple contexts
Hi Anna, Robbert, I think the bufferswaps on window are by default not synchronized, a call to wglJoinSwapGroupNV(HDC hdc, GLuint group) is needed to make different windows synchronize. the osg lib has the code to make the call, just set traits-swapGroupEnabled = true; before createGraphicsContext(traits); Output should look like: (set OSG_NOTIFY_LEVEL=INFO) GraphicsCostEstimator::calibrate(..) GraphicsWindowWin32::setSyncToVBlank on GraphicsWindowWin32::wglJoinSwapGroupNV (0) returned 1 GraphicsWindowWin32::wglBindSwapBarrierNV (0, 0) returned 0 the wglBindSwapBarrierNV fails if you don't have a gsync card (hardware connection card for multiple graphics cards) Still, as Robbert says, a single graphics window is likely to perform better, and is of course automatically in sync. But I suppose you don't want fullscreen with stereo mode VERTICAL_SPLIT. Laurens.

Is there a reason why you need two separate windows rather than a single window with two views? Robert.

Re: [osg-users] [osgPlugins] png plugin - problem loading images
Hi Andrey, Just assuming the libpng15.dll is the one you build from source, and not something you happened to have in your path.. renaming the way you did is not very likely to work, an executable should now the name of the dll it wants to use, and will fail to start if you renamed it. However, the libpng15.dll itself tends to depend on libz.dll (or libz1.dll) - the one you build. that should also be in your path. Laurens.

PAT 3 contains a geode with a green geometry, positioned at 100/100/100. The camera projection matrix is basically a hud.

Re: [osg-users] PagedLOD - Trying to understand climbing mem usage
Hi Sukender,
Just a guess here,
when you say
Generate a PagedLOD, to load 'groupFile'
do you call PagedLOD::addChild(Node *child, ) ?
for the pageLOD will then hold the child in memory until
PagedLOD::removeExpiredChildren() is called. Normally this is done in
the frame loop (in updateSceneGraph()) but I think you're not in a frame
loop (yet).

Re: [osg-users] valgrind, memory leak debugging
Hi Thomas, I did a quick read of your code, and the first thing I notice is that the osgDB::readNodeFile result is assigned to a osg::Group*, NOT a osg::ref_ptrosg::Group . The pointers run out of scope at the end of generateSimplifiedNodes, mergeNodes seems to take most of the geometry, but this looks like a leak to me. Laurens. On 5/2/2010 8:07 PM, Tomas Hnilica wrote: Hello OSG users, I am working on a project that processes large amount of data a have problems with memory leaks. Problematic part of the code does simplification of OSG subgraphs and writes out the results. In this code, no graphical window exists, it's only about reading - processing - writing of .ive files. The code reads in two .ive files, merges the geometries in these files, does simplification on the merged geometries and writes the result to the .ive file. On very large models the system goes out of memory in the simplification phase. There must be some memory leak in the code, I guess in the merging phase, because this is done by myself :) During the process in the single simplification step, the memory is allocated and then deallocated, but not to the same amount as before (that may be OS allocation strategy specific). When the process goes through several simplification steps, the amount of overall reserved memory increases (this is what MS Windows task manager says). I tried to find the problem with valgrind on Linux, but it reports loss of memory in the OSG code, what is probably wrong interpretation. Does anynone use valgrind for memory leak detection in OSG apps or can you recommend other method? I attached simplified snapshot of incremented piece of my code, if different eyes could have a short look I would highly appreciate it - maybe there is only wrong usage of readNodeFiles, merging data or osg::ref_ptr's...it seems that only small portion of the allocated memory is not deallocated.

Re: [osg-users] Refreshing a Scenegraph
Hi Suvajit, From your description I suspect that your problem is caused by the osg object cache. try osgDB::Registry::instance()-clearObjectCache(); before the ReadFile() to see if that's the problem. If that helps you might want to just supress the usage of the cache for this readfile call: osgDB::ReaderWriter::Options* opt = osgDB::Registry::instance()-getOptions(); if (!opt) opt = new osgDB::ReaderWriter::Options(); opt-setObjectCacheHint(osgDB::ReaderWriter::Options::CACHE_NONE); osgDB::Registry::instance()-setOptions(opt); readFile() opt-setObjectCacheHint(osgDB::ReaderWriter::Options::CACHE_ALL); osgDB::Registry::instance()-setOptions(opt); Cheers, Laurens.

Re: [osg-users] Static linking with user pulgins AND dynamic OSG?
Hi Sukender,
I still think that it should work, and the problems you discribe sound
like you have different #defines for the plugin and the main executable,
possibly caused by different include path (or order in the include
path). Possibly different compiler settings (esp. C/C++-Code
Generation-Runtime Library).
To check you could dig up the compler command line from the BuildLog for
the executable and the static lib objects, something like
/O2 /Ob2 /I X:\osg\3rdparty\include /I X:\osg\OpenSceneGraph\include
/I X:\osg\vc9\include /D WIN32 /D _WINDOWS /D NDEBUG /D
_SCL_SECURE_NO_WARNINGS /D _CRT_SECURE_NO_DEPRECATE /D
WIN32_LEAN_AND_MEAN /D _WIN32_WINNT=0x0500 /D
CMAKE_INTDIR=\Release\ /D _MBCS /FD /EHsc /MD /arch:SSE2
/Foosgrc.dir\Release\\ /FdX:/osg/osgRC/lib/Release/osgrc.pdb /W3 /c
/TP /Zm1000 /MP
I suspect there is a difference. If they match the .obj file will be
effectively identical, so the linker should behave identical.
The option to use the .obj files instead of the .lib is avialable in
visual studio if the projects are part of the same solution, in the
property's for the executable:
Configuration Properties-Linker(-General) set
Use Libraray dependencies: Yes
(and make the exe project dependent of the .lib projects and remove the
.lib from Linker-Input Additional Dependencies if this is not already
the configuration)
Use Libraray dependency Inputs: Yes

Hi Laurens,
Many thanks for the examples and the modified readers. I don't have time to
browse it right now but I will soon.
Well, USE_OSGPLUGIN() in Main.cpp causes linker to complain about duplicated
symbols (inline methods in osgDB). I think this is because the compiler can
silently refuse inlining and thus create the methods' code in each .cpp. I
didn't find a way to work around this, except:
- Making OSG static (which is what I don't want, for multiple reasons)
- Directly including reader-writers code into my project (it works as expected)
If you know a way, please tell !
It would be nice to tell CMake to directly include .o/.obj files from a project
into another one at link-time, but I guess it's a bit tricky and non portable...

Hi Sukkender,
if you are linking whith the .lib the USE_OSGPLUGIN() is required. -
Unless your project is set up to silently ignore the lib file and link
the .obj files instead. (can't find the option atm.)
What is the effect of the USE_OSGPLUGIN() in the Main.cpp?
Attached is a reduced version of my project whith all the plugins,
where
our viewer has been replaced by the osgviewer. The cmake files
generate
dynamic link libs (osgdb_dds.dll) and always stuff the plugin into the
final .exe too.

Hi Laurens, hi all,
Hum, could you give me a hint, please? If I write:
class BBB : public osgDB::ReaderWriter {... blah blah blah ...};
REGISTER_OSGPLUGIN(bbb, BBB)
in bbb.cpp (in my main exe), then the BBB reader/writer is
constructed and added to the registry when process loads.
However if I put that .cpp in a static lib, which is linked to my
main
exe, then the BBB reader/writer is never built (nor added to the
registry).
As far as I know, static libs are roughly a bunch of objects!
Were's
the difference?
And of course, using USE_OSGPLUGIN() doesn't work.
BTW, The feature you're mentioning seems interesting. Is there any
chance you release the code, under a licence or another?

For the version you are using, I am guessing that your link

originate in compliling the static plugin lib with
OSG_LIBRARY_STATIC

Mixing debug and release versions will also create confusing link

Of course the USE_OSGPLUGIN(ext1) must be mirrored by a

Re: [osg-users] OSGEXP building problem...
Hi Alessandro, I usually build the exporter with a static linked osg, so I have no recent experience with your problem.
