Later I use this to get the window coordinates:
pWindow0 = p0 * _modelToWindowMatrix;

I set multi sampling with the following code:
ref_ptr< DisplaySettings > displaySettings = new DisplaySettings;
displaySettings->setNumMultiSamples(16);
displaySettings->setMinimumNumAlphaBits(8);
modelView->setDisplaySettings( displaySettings.get() );

I think I just did
apt-get build-dep openscenegraph
which will install everything you need in order to build osg itself.
I did this successfully on Ubuntu 8.04, but it should work for the stable
release too.

I have tried to enable multi sampling, but it has no effect. This is how I try
to activate it:
modelView = new osgViewer::View;
modelView->setUpViewInWindow
(400, //x
0, //y
640, //width
480); //height
modelView->getCamera()->ge
If it's not a Geode, it's probably a Group. Look for the Geode among your Node's
children. This approach may be easier if you always load the same model.

You need to set the loaded image as the texture on a polygon node.

I check if the intersection belongs to the correct node:
osgUtil::LineSegmentIntersector::Intersections intersections;
osgUtil::LineSegmentIntersector::Intersections::iterator intersection;
marked.isActive = false;
bool result = viewer->computeIntersections
You probably tried
osgViewer::View::setUpViewAcrossAllScreens ()
if you have one desktop on two screens, or
osgViewer::View::setUpViewOnSingleScreen (unsigned int screenNum=0)
, one for each viewer, if you have two desktops.
If so, what happened?

I have used 3dldf (http://www.gnu.org/software/3dldf/) earlier to create
vector graphics from 3d models. It would be extremely cool to extend osg
to create vector graphics output with an SVG Viewer! Imagine infinite

This would be really difficult, since you can't use depth
You have to set both the view matrix and the projection matrix of the
camera.
The view matrix is the pose of the scene coordinate system in the camera
coordinate system.
Use
voidsetViewMatrixAsLookAt (const osg::Vec3 &eye, const osg::Vec3

I too need to show images. Since osg is (and should be) 3d-based, the
way to do is seemed to be to display a rectange Geometry infront of an
orthographic camera, and set the rectangle texture to be the image.
Instead of this, I chose to use OpenCV (CV for Computer Vision), but you
can also use
I order to debug the osg program I am currently working on, I have
written some functions to print the scene graph as text. For instance,
notify(NOTICE) << myNode;

force the camera manipulator back to its home position.

I try to add Geoms to the scene of my running osgViewer::Viewer. If I

They are added to a Switch in the scene, and they are set to be visible.
