I use the LineSegmentIntersector in my application to select planar faces. The problem is that sometimes when I click on the "face facing to you" (check the red "X"es on the picture), I get no intersection of this face. I get only an intersection on the face which is "not visible" from this view - the bottom face. Then sometimes it happens, that the user wants to select a face, but an "invisible face" is selected instead, but he doesn't know it because he doesn't see it, even if its highlighted.
i made this sample application to simulate my problem - when I click on the positions where the red crosses are, normally I should get 2 intersections - first the face where I drew the red crosses and then to bottom face which we don't see. Sometimes, I get only the second (see the debug output on the picture). I think this is a problem. Thank you!
