No, I do not consider this a bug. As a polytope has no concept of "near" or "far" the order of the result is actually arbitrary. Of course the method-name "getFirstIntersection" is misleading... To overcome this shortcoming I introduced the concept of "ReferencePlane" to the PolytopeIntersector which probably does what you want but my modifications did not make it into OSG 2.2. If you must use 2.2, you could try to take the PolytopeIntersector from the current OSG dev Release, rename it to MyPolytopeIntersector and use with 2.2. > Thanks in advance > Gianluca Peter -- ________________________________creating IT solutions Peter Hrenka science + computing ag Software Solutions Hagellocher Weg 73 phone +49 7071 9457 263 72070 Tuebingen, Germany fax +49 7071 9457 511 [EMAIL PROTECTED] www.science-computing.de -- Vorstand/Board of Management: Dr. Bernd Finkbeiner, Dr. Florian Geyer, Dr. Roland Niemeier, Dr. Arno Steitz, Dr. Ingrid Zech Vorsitzender des Aufsichtsrats/ Chairman of the Supervisory Board: Prof. Dr. Hanns Ruder Sitz/Registered Office: Tuebingen Registergericht/Registration Court: Stuttgart Registernummer/Commercial Register No.: HRB 382196 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
