I think you would want to put MatrixTransform on top of the pyramid node and
update its matrix either thru updatecallback or outside your frame.
Something like this
class UpdatePyramidNodeCallback : public NodeCallback
{
virtual void operator()(osg::Node* node, osg::NodeVisitor* nv)
{
osg::MatrixTransform* mx = dynamic_cast<osg::MatrixTransform*>(node);
//here you set up your matrix with your XYZ HPR
mx->setMatrix(mx)
}
};
main(...)
{
...
osg::MatrixTransform* mx = new osg::MatrixTransform;
mx->addChilc(pyramidNode);
mx->setUpdateCallback( new UpdatePyramidNodeCallback )
