animation on HUD geomtries

Hi,

I was wondering if somebody made animation on HUD. 

basically, I am modifying osgpick example trying to animate the 5 geometries rendered as HUD. I am using
PositionAttitudeTransform, but all I got is the static geometries.  Is it impossible to animate 2D nodes
rendered as HUD, please hint me if I am missing something?

 Here is the code

osg::PositionAttitudeTransform *pat;

/* update function*/

void update(float dt) {
    pat->setPosition(osg::Vec3(dt, dt, 0));

}

/* main function */

int main()
{

....

    osg::ref_ptr<osgText::Text> updateText = new osgText::Text;

    // add the HUD subgraph.   
	osg::ref_ptr<osg::Node> hudCam = createHUD(updateText.get());

Re: animation on HUD geomtries

Hi,

I think you made a mistake when setting up the scenegraph. Add
updateText to your pat, and add the pat to your hud.

HTH,
