Hi guys, I have encountered a small problem with intersections. I am using the IntersectionVisitor and the LineSegmentIntersector to clamp objects to a geocentric terrain built with VPB (VPB head w/ OSG 2.6).
Most of the time it works. But when the intersector line segment is exactly coincident with a terrain tile boundary (at the highest LOD) at the skirt underneath it, the intersection test will sometimes return zero intersections. Not at every tile boundary, but definitely at some. I came to this conclusion be rendering my line segment and seeing it exactly coplanar with the skirt geometry between the tiles. I would appreciate any ideas or suggestions on how to track down this issue. Thanks, Glenn -- Glenn Waldron : Pelican Mapping : http://pelicanmapping.com : +1.703.652.4791
