Hi All, I have a quick question. I'm playing with picking objects in a scene using the pickhandler example. The scene is essentially a big box whose faces face inwards. Within the box I have a smaller box whose faces face outwards. If I am outside both boxes, looking into the outer box, the pickhandler returns both the outer box, face that I have hit, and the inner box faces that I have hit. As the outer box face is actually facing away from me, I want to exclude it. Is there an easy way to do this?
My thinking was that I essentially need to look at the normal of the face that I hit, and the direction of view vector for the camera, take the dot product, and if positive exclude it. Does this sound right? Is there an easier way/structure that I should use? Many thanks for any help Neil. _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
