The attachment scheme seems to be an attribute of Tracs, in someways

thanks for your reply. I switched to using the Viewer class. The code is:
#include osgViewer/Viewer
using namespace osg;
int main()
{
osgViewer::Viewer* wnds = new osgViewer::Viewer();
I'm working on it. Slowly...
There is also the work of Simon J. Benson.
I'll keep you informed as soon as something happens.
Ciao!

The code wasn't pseudo code. It compiled well. Of course it is useless

Here is what i found out:

Hi Matthias,
Since 2.0 I have integrated a bug fix into osgViewer to handle the
case of no scene graph being assigned before realize(), so this will
probably fix the crashes you've seen.

Hi all,
as far as I can see, it is possible to set the background color of viewers,

I noticed a flurry of e-mail regarding VRML and happen to need to view

is not available.
