Well that's easy enough:
osg::Matrix MVPW(camera->getViewMatrix() *
camera->getProjectionMatrix() *
camera->getViewport()->computeWindowMatrix());
osg::Vec3 posIn2D = posIn3D * MVPW;
Thanks.

Alex,
The short answer is "no".
However, this question has already been addressed...

Subject: [osg-users] transform to screen function
Is there some easy function on the osg::Camera (or some other osg class) that I
can call to compute the 2d screen position of a 3d point? I couldn't find one
when looking through the documentation, but I figured I would ask just in case
I am missing it.
Thanks.
Alex
