    This simply means that you are changing the coordinates in the object's own matrix, without any transformations. I.e. the coordinates are in the parent's coordinate system.

    To get your kind of translation, use this function
    MoveObject(obj, trans)
{
  obj->SetPosition(obj->GetPosition() + 
                   obj->GetMln()->GetMulV(trans));
}

    where for example trans=vector(100,0,0) moves obj 100 units along its X-axis. (The trans vector is transformed from within the local system of the object to the parent's system.)
