thanks. i change the code as you recommended.

the first call works, and in the subsequent calls, i print debug data, which
show that the pose has changed. i have now added the following code to see if
the changes are actually accepted by "transform".
OSG::Matrix m = transform->getMatrix();
OSG::Vector<OSG::Real32,3> position;
OSG::Quaternion rotation;
OSG::Vector<OSG::Real32,3> scale;
OSG::Quaternion scaleOrientation;
OSG::Vector<OSG::Real32,3> center;
m.getTransform(position, rotation, scale, scaleOrientation, center);
cout << position << endl;
it turns out, they are. the values in m.getTransformation --> position are the
same as in my pose.position.
i paste the entire code in:

(its not that big)
the function update() is called from outside periodically.
cheers,
keyan
