Hi RJ,
Where would you like me to start it's rather an open ended
question. Are you talking about which thread it's generated from?
Where SceneView itself is used? W.r.t osgViewer? Standalone
SceneView usage? osgProducer? it's easier to answer a question
once given context.

Hi All,
I am trying to understand how does OSG create the _renderGraph from the
SceneGraph. I am not able to understand where exactly this process is
happening in the OSG, I tried to browse the code but not able to get
much of the information. Can somebody provide me some pointers in the
source

You always have to call cull() before draw(), even
osgViewer::Viewer::renderingTraversals()
does this internally. cull() is what culls the scene gr

SceneView is pain to support because...
SceneView has no support for event
Hello at all,
I have a short question about the osgUtil::SceneView.
What advantages or disadvantages has the SceneView compared to the
osgViewer::Viewer?
Cheers,

Makes sense doesn't it? If you don't call cull() then draw() is kind-of in an
indeterminate state.

Hi,
I'm using PRE_RENDER cameras rendering to FrameBufferObjects with
SceneView, in some cases multi-pass as well. I've used a similar setup
as per the osgprerender example and did not find a difference between
using SceneView versus osgViewer. I'll splat some code into the bottom

Hi John,
As you are rolling your own viewer its really open ended how you are
doing things, so its hard to know where to start. Are you using
pbuffers? frame buffer objects? How are you creating graphic
contexts?
Personally I'd recommend using osgViewer, it does mean that you know
it'll work

Hi John,
Could you write questions one per line rather than writing half a
dozen in a single paragraph - if you want answers you have to make it
easy to people to read and reply.
As for texture object clean up, there are two things - releasing the
GL objects and then flushing these GL objects. P
I manage my own OpenGL texture sharing. Each of my multiple OS-Windows
has a SceneView and the scene graph is shared. When I set my smart
pointers to zero, it seems as if the textures are not properly
unloading. This is a big problem for us. How can I correct it? If I
extend GraphicsWindowEmbedded?

HI ?,
Please have a look at the osgviewerQT example that is part of OSG 2.0
onwards, it doesn't require the use SceneView.

Hi,
I'm looking for a osgUtil::SceneView example I can use to integrate
osg with Qt's QGLWidget. Is it possible to just use raw OpenGL code
inside scenegraph nodes ? Is there an example ? The lack of
documentation (and my unwillingness to read source code) almost forces
me to use OpenGL comman

HI Zullizum,
Could you break the various problems you've seen out into separate
emails send to osg-users so we can work through them one at a time,
and if there are bugs resolve them before 2.2.
