Hi Guy,
To set the size and position of a window you use the

/** Set the window's position and size.*/

The GraphicsContext::resized() method only informs the context that
the window has

right?
but my sky sphere seems not properly to be moved, because i set its center to
the camera pos per frame, so maybe i should scale it according to somethig like

Yes, two different groups in the scenegraph under the same camera, but I
cheat the large object part by scaling it and moving it closer to the
camera, so there is no risk of clipping due to the cull settings.

I've implemented the osg::GraphicsContext::ResizedCallback to get notified when

However, I also need to change the window size programatically (when the user

Hi,
I've been struggling with configuration names on the Xcode project that comes
with OSG.
The problem I have is that it causes "no such cnfiguration" errors when I use
xcodebuild
from a helper shell script because the configuration names contains white
spaces (like Deployment 32bit Carbon.)
Something that I have done (please let me know if this is not a good way to
do it or if there is a better way), is to break up my scene into parts. I
have the "large distant" things in one part of my scene graph, and then
everything else in another part. I then render them in separate render
bins

You have to re-create the graphics context if you want to change the

Hi James,
Do you want to testing culling from within the cull traversal itself,
or do you wish to just test against the view frustum polytope
independently from the cull traversal? For the later I'd just use an
osgUtil::PolytopeIntersection in conjunction with
osgUtil::IntersectionVisitor.

you just need to pass a model to draw, like : osgViewerQT cow.osg
You can open any model supported by OpenSceneGraph...

Hi,
you can also make another RTT camera that looks at a part of the first
camera's output and just renders to another texture at the time you
