Hi,
look at the intersection code in osgmovie. I think it gets the texture
coords of intersection.

Hi,
Does anyone know how to access the rgba texture values at the point of
intersection in a polygon found using osgUtil::IntersectionVisitor and
osgUtil::LineSegmentIntersector? Ideally I would pass a threshold to the
IntersectionVisitor so that it automatically skips intersecting polygons whose
alpha values at the intersection point fall below the threshold. Since this
functionality does not seem to exist, I am wondering if there is another means
available to find this information. I am hoping that I do not have to write a
new IntersectionVisitor.
Thank you!
Cheers,
Matthew
