Hi Nathan,
Thanks for the example. I can reproduce the picking problems using:
osgpick singletree.osg
So thumbs up there. As to the cause, it's almost certainly a bug in
the computation of the matrix that should be positioning the
billboard, or the lack of coordination of point at which the

issue.
I'm afraid I'm
Hi,
I'm having trouble getting picking (via View::computeIntersection) to work on
Billboards in POINT_ROT_EYE mode. Attached is a .osg file that creates a
single billboard tree -- if I open this file with osgPick in OSG 2.9.5, I can
only get a hit if I click near the very base of the tree.

I tried tracing this through IntersectionVisitor and I couldn't figure out
why it didn't work. I have two guesses:
1. A precision problem in the matrix math or
2. The billboard matrix is coming out differently in the visitor than in the
actualy cull traversal. It seems to
