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 ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=18906#18906 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
