[osg-users] How to get the camera in UpdateCallback Node?

[Geo Xin]

Hi,
osg::Matrixd mt;
mt->setUpdateCallback (New UpdateNode(camera));

class UpdateNode::: public osg::NodeCallback
{
osg::camera* camera;
UpdateNode(*camera)
{camera=camera;}
operate(osg::Node* node, osg::NodeVisitor* nv)
{
mt=camera->getMatrix();
traverse(osg::Node* node, osg::NodeVisitor* nv);
}
}

If can I use this way to get the camera in every Callback?

If not,how can I get the camera in UpdateCallback Node everytime?

Thank you!

Cheers,
GeoXY
