| Summary | 0031941: Tests - some test cases in lowalgos/intss are wrong | ||||
| Description | Test lowalgos/intss/bug29972_4 was speciality designed for diagnose possible loops (self-intersections) of curve, which is result of intersection bspline surface and plane. Now test is considered as OK - intersection curve is good and has no loops. Really intersection curve is wrong and has loop, see attached picture. Algorithm of test is wrong. Test lowalgos/intss/buc60623_3 is wrong. In test script topological command "checksection" is applied for geometry object - curve and always return "good" result: .... mksurface S1 a mksurface S2 b intersect I1 S1 S2 regexp {nb alone Vertices : ([-0-9.+eE]+)} [checksection I1] full cs2 if { $cs2 != 0 } { puts " Faulty : Intersection is not correct" } else { puts "Intersection of S1 and S2 is correct" } ... This test tests nothing. Test lowalgos/intss/bug139 is wrong. The same reason as for buc60623_3 | ||||
| Steps To Reproduce | Run test lowalgos/intss/bug29972_4 and zoom middle part of result curve. | ||||
