If the node you found isn't derived from DOFTransform then the dynamic_cast
will fail.
Since you mention osg::Geode maybe you should cast to that instead, if that is
what it is?

Is 'addFunction' an osg function or is it from your framework? I can't find
any reference
to that in the soruce.

That’s similar to what I had in mind. Capture it to a loop buffer (file or memory), then convert the images from the back of the loop, forward and save them as a image sequence. That way, the capture function can run at its pace and the converter function can run at it's own slower pace. I crammed a sequence of bmp files and maid an avi movie file way back when I was learning to do animation with a digital camera on windows 3.1 platform. Yep! All that art school and its funny how I wound up hacking code for a living! |-) I guess, that the concept hasn't changed all that much! Right?

[osg-users] osgAnimation : 02AE6A28 RigTransformSoftware::UniqBoneSetVertexSet no bones found
Hi,
The change in the bone class was on my feature request list for osgAnimation
:-) as its quite confortable to get the inverseBindMatrix from Maya, especially
if the Charecter is animated and not in bindPose.
But in any case, the issue that I have is still there with your trunk. I
created a minimal scengraph to demostrate missing UniqueIDs. Notice that if
animationManager is not a ref_ptr, the UniqueIDs don't get written into files.
The same is true for skeletton and bone. With unique IDs I get no error.
Isn't this wrong behaviour ?

osgAnimation::BasicAnimationManager ;

Re: [osg-users] WriteImageFile black
Hi Tomas, - I tried to use the ScreenCaptureHandler, but this doesn't allow me to achieve what I want (I want to record several frames during a given period) because of the fact that it only takes screenshots when you press a key. First of all, in the SVN version of the ScreenCaptureHandler, it has a mode that allows continuous capture (with a way to stop it of course). In osgviewer you can even try it out, pressing 'c' (lowercase) will capture a single frame and pressing 'C' will start/stop continuous capture. If you're not using the SVN OSG and can't upgrade, then you can override the ScreenCaptureHandler class and make the changes I made (look at the code in SVN and do the same in your overridden class). I think the basic idea was, in the overridden handle() method, on FRAME events, call addCallbackToViewer(). But look at the code in SVN to be sure, it's been a while. I really am starting to be in a rush for this project, and getting depressed by the complexity of getting a simple shot of the view. Well, OpenGL and OSG are complex. But you're right, this was a very common request, which is why I tried to make the ScreenCaptureHandler easy to use and flexible. Hope this helps, J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] WriteImageFile black
Hi everybody,
First, I want to state that I am aware there is already quite a few posts about
this. I read most of them, trying to understand what is wrong with my
application; now that this is said, I can also state that I did not find out
the solution.
Basically, I am trying to achieve the same thing as a lot of people, taking a
screenshot of my current view and writing it to file. I really tried a lot of
ways to get this working, in vain.
:
- I tried to use the ScreenCaptureHandler, but this doesn't allow me to achieve
what I want (I want to record several frames during a given period) because of
the fact that it only takes screenshots when you press a key.
- I tried to have a look at osgscreencapture, which is unfortunately too
complex for me to get it clearly.
- I tried the basic
Code:
osg::Image* temp = new osg::Image();
temp->readPixels(0, 0,
viewer->getCamera()->getGraphicsContext()->getTraits()->width,
viewer->getCamera()->getGraphicsContext()->getTraits()->height, GL_RGB,
GL_UNSIGNED_BYTE);
osgDB::writeImageFile(*temp, toto.jpg);
which gives me the result I have now (a black jpg file).
- I also tried to put that code in a handler derived from GUIEventHandler
Code:
bool ScreenshotHandler::handle(const osgGA::GUIEventAdapter&
ea,osgGA::GUIActionAdapter& aa)
{
osg::View* viewTest = aa.asView();
osg::Image* temp = new osg::Image();
temp->readPixels(0, 0,
viewTest->getCamera()->getGraphicsContext()->getTraits()->width,
viewTest->getCamera()->getGraphicsContext()->getTraits()->height, GL_RGB,
GL_UNSIGNED_BYTE);
osgDB::writeImageFile(*temp, "toto2.jpg");
return true;
}
that I add to the viewer, but I still get the same problem.
I really am starting to be in a rush for this project, and getting depressed by
the complexity of getting a simple shot of the view.
Please help!
Thank you!
Cheers,
Thomas[/code]

[osg-users] serializer again: stream sizes an some questions
Hi,
I'm working again on my serializer problem and I don't unterstand why my binary
stream is as long as my ascii stream. binary should be smaller as ascii I
suppose
My Testcode code is:
Code:
// Writing object to stream
std::stringstream myOstream;
std::string extension = "osgb";
bool compressed = true;
osgDB::ReaderWriter* rw =
osgDB::Registry::instance()->getReaderWriterForExtension(extension.c_str());
if ( rw )
{
osgDB::ReaderWriter::WriteResult wr;
if (extension == "osgb")
{
if (compressed)
wr = rw->writeObject( *test, myOstream, new
osgDB::Options("Compressor=zlib") );
else
wr = rw->writeObject( *test, myOstream );
}
if (extension == "osgt")
{
if (compressed)
wr = rw->writeObject( *test, myOstream, new
osgDB::Options("Ascii Compressor=zlib") );
else
wr = rw->writeObject( *test, myOstream, new
osgDB::Options("Ascii") );
}
if (extension == "osgx")
{
if (compressed)
wr = rw->writeObject( *test, myOstream, new
osgDB::Options("XML Compressor=zlib") );
else
wr = rw->writeObject( *test, myOstream, new
osgDB::Options("XML") );
}
if (!wr.success() ) OSG_NOTIFY( osg::WARN ) << "ERROR: Save
failed: " << wr.message() << std::endl;
}
else
OSG_NOTIFY( osg::WARN ) << "error getting readerWriter for
osgt" << std::endl;
// Get size.
stringbuf *pbuf;
pbuf = myOstream.rdbuf();
OSG_NOTIFY( osg::WARN ) << "PBUF Bytes available: " << pbuf->in_avail()
<< std::endl;
OSG_NOTIFY( osg::ALWAYS ) << "STRING Bytes available: " <<
myOstream.str().length() << std::endl;
OSG_NOTIFY( osg::ALWAYS ) << "STRING content: " << myOstream.str() <<
std::endl;
//Reading Stream to node
if ( rw )
{
osgDB::ReaderWriter::ReadResult rr = rw->readObject( myOstream
);
osg::ref_ptr test2 =
dynamic_cast(rr.takeObject());
if (test2)
{
OSG_NOTIFY( osg::WARN ) << "TEST::FrameID is: " <<
test->getFrameID() << std::endl;
}
else
OSG_NOTIFY( osg::WARN ) << "Error converting stream to
Node" << std::endl;
}
My Question is: What is the real stream size:
The value pbuf->in_avail() or the value myOstream.str().length()?
Because it always differs up to 60 bytes.
My stream sizes ( myOstream.str().length() ) of my object ot transfer are:
xml: 739 bytes
ASCII: 389 bytes
binaryy uncompressed: 353 bytes
binary compressed: 176 bytes
Can anyone give me a hint what the problem in my serializer / stream usage,
that causes my binary stream to be as large as my ascii stream?
Thank you very much!
Cheers,
Torben

[osg-users] Support vendor specific 3D APIs - any interest here?
Hi, So quad buffered stereo only works with professional graphics cards, and I have used that feature with success at my work place. At home I do not have access to such devices. But I do have a 120 Hz capable monitor and those nVidia 3D Vision shutter glasses, which unfortunately only support DirectX gaming and stereo viewing of video and still images. This is mostly targeted at a gaming audience and OpenGL is no longer relevant enough to be supported (what a shame!). But nVidia have created a proprietary API (NVAPI) with which it is possible to display pretty much anything with shuttered glasses. Would there be any interest to fit OpenSceneGraph with a capability to render to 3DVision enabled displays with non-Quadro graphics cards? Is support for proprietary APIs and extensions frowned upon in this community? (I hear ATI have a similar vendor specific shutter glasses API in their latest drivers) Christian ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Then i will be able to dig it Cheers, Cedric -- Provide OpenGL services around OpenSceneGraph and more +33 659 598 614 Cedric Pinson mailto:cedric.pin...@plopbyte.net http://www.plopbyte.net On Mon, 2010-04-05 at 12:26 +, Peter Wrobrl wrote: > Hi, > > but how can this be a version issue ?

[osg-users] osgAnimation : 02AE6A28 RigTransformSoftware::UniqBoneSetVertexSet no bones found
Hi, but how can this be a version issue ? I have created both the osg files with OpenSceneGraph 2.9.6. Figured out something, those Unique_Ids get written only if ref_ptr is used instead of normal pointers ( for e.g. BasicAnimationManager ), can this be this true ? I will try your trunk. Thank you!

Re: [osg-users] [vpb] binaries of osgDem
Hi, hmm don't know the solutiuon... but instead of building vpb without full osg, why don't you download an compile osg full? it works out of a box, just downloading, and compiling, and the everything should work!

Re: [osg-users] 2.8.3 press release
Can somebody provide me with a .zip version of 2.8.3. I don't have access to SVN (through my firewall) and I believe it will fix one of my problems.

Re: [osg-users] 2.8.3 press release
There's a typo "oagAnimation" instead of "osgAnimation". Christian ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] osgAnimation : 02AE6A28 RigTransformSoftware::UniqBoneSetVertexSet no bones found
Hi Peter, You seem to use an old format of osgAnimation, the trunk of osg has moved a lot regarding osgAnimation. Could you have a try with the trunk of osg ?

Do you call dirtyBound on your drawable after updating the endpoints of your line? This is a common pitfall for me, when doing dynamic geometries. cheers, Stephan ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

John, eye and center are not vectors but points. When you use them in setViewMatrixAsLookAt, you actually mean "from eye to center". -- Alberto ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
