7a2900e238 Added osgUtil::Intersector::PrecisionHint member and set it's default to USE_DOUBLE_COMPUTATIONS, and implemented support for use double or float maths internally in LineSegmentIntersector and RayIntersector classes 2013-11-07 12:35:34 +00:00

7cd74f0282 From Farshid Lashkari, "Another update. I added a LIMIT_NEAREST enum which implements your previous suggestion of rejecting bounding volumes further from the nearest existing intersection. I only implemented this for LineSegmentIntersector. I'd appreciate it if you could double check the math I added to LineSegmentIntersector::intersects() for checking if the bounding sphere is further away. The results of this are promising. I'm getting noticeable performance increase for line intersections with scenes containing many drawables.
