Hi,
some things you could try:
* switch whatever viewer you have to singlethreaded and see if the
problem persists. E.g.
v.setThreadingModel(osgViewer::Viewer::SingleThreaded);
* make sure the datavariance of the node is set to dynamic, e.g.
-setDataVariance( osg::Object::DYNAMIC );

Hi,
fix attached. There is no magic here, you should have been able to find
out the problems by looking at the osg examples.
You forgot to attach the prerender camera to you main scene. Also, the
prerender camera usually operates in the default OpenGL coord system, ie

How can i test the GL_RGBA32F_ARB render to texture quality. i don't know
whether i did a mistake in programming or my Nivida quadra fx 570m with
windows vista driver doesn't support it.
Or do i have to generate an own graphic context for enabling this feature?

Most of the project builds fine but fails

Hi Ufuk;
As I know, If you create a new object with using ref_ptr, object's default
ref_ptr should be initialized to 1. And after you have attached it to your
scene, ref_ptr count gets 2. And after you delete your geometry from your
scene graph ref count gets 1 again. And then this ref_ptr object

Single threading it seems to work. My guess is that the callback is trying to

Hi Kris,
Set the DataVariance of the Text object to DYNAMIC, then you'd be able
to use all threading models safely, the problem is that you are
changing the text at the same time as it's been read by the draw

err one way you could put a break point in the reference pointer class
where the ref count gets increased
you can make this a conditional with some like if the THIS pointer = the

Hi Ufuk,
You don't need to know the address of your geometry at compile time.
Put a break point on the place where you create the geometry.
Run to that point and make a note of its address (or copy it to clipboard).
Set a break point in Referenced::ref and right click on the red breakpoint
Of course you spotted the deliberate mistake... should be this==0xblahblah
