osgText doesn't seem to compute it's bound/center correct. Any

Depending on how you set up osgText the bounding volume will be computed differently, and it often is view dependent so its bounding volume can even change from frame to frame.
Robert.
I have noticed the same problem. Looking
into osgText::Text it appears as though it cannot return a proper bounding
sphere centroid until after the first time it's drawn (?). It returns (0,0,0) as
the centroid instead. If your Text's Geode starts out under an LOD, the LOD
cannot get a proper centroid to determine when to switch the Text in the first
time around. (I am using autoRotateToScreen but I don't know whether that
matters.) I am currently working around this by setting the LOD range to
maximum, then using an update callback to set the proper LOD range after the
second update traversal. -gw
