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?
