Hi Fred,
have a look at this thread:
http://thread.gmane.org/gmane.comp.graphics.openscenegraph.cvs/4868/focus=4876
I'm not sure what the current float vs double in the intersection code
path is like, but maybe you can try do some mods and see...

Hi,
I'm trying to do picking by using computeIntersections.
Please find the attached picture (skydome).
Balls represent intersection points, lines represent normal vectors.
Whenever I try to pick the top of the dome (not the inside), I get a
correct intersection point but the normal vector is wrong. When I
pick from the inside the yellow lines go downwards, as expected.
I have noticed other strange behaviors with more complex models.
Sometimes, the first intersection point/normal vector pair is not
returned. Other times, the intersection point and/or the normal
vector is wrong.
We're using OSG 2.8.1 but I tested a recent version and experienced
the same issue.
Is this a known bug?
Thanks, Fred
