I can not say I fully understand this code but I would say that the problem is probably more associated with the "epsilon = 1e-4" code in LineSegmentIntersection::intersectAndClip than any discrete math problem. This results in _e.z having a -0.0001 value and _s.z having a 0.0001 value which then effects the remap_ratio. I'm using OSG 2.8.3. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=29600#29600 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
