Hi, i wrote a script to test the BRepExtrema_DistShapeShape stuff again: http://pastebin.com/2ei6dgja
Could you please verify if it is really an issue with BRepExtrema_DistShapeShape and not my bad coding? It hangs my machine with approximately n > 1300. For n = 1000: :~$ time python test_BRepExtrema_DistShapeShape.py real 0m42.641s user 0m39.758s sys 0m2.740s # Excerpts from /proc/cpuinfo: processor : 7 vendor_id : GenuineIntel cpu family : 6 model : 42 model name : Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz #... /proc/meminfo: MemTotal: 16412732 kB :~$ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=12.04 DISTRIB_CODENAME=precise DISTRIB_DESCRIPTION="Ubuntu 12.04.2 LTS" Regards, Uwe On 09/08/13 19:05, Uwe Schlifkowitz wrote: > Hi Charles, > > my edges are indeed segments.
