From 0cbfb9f15140fce08ac4fac39bb34ed0da69b0fa Mon Sep 17 00:00:00 2001 From: aml Date: Thu, 13 Aug 2015 11:04:03 +0300 Subject: [PATCH] 0021564: Intersection of two planar faces produces curve with too many poles I ComputePurgedWLine() function: Excess points in walking line are deleted when: 1) Distance between neighboring points too small. 2) Points lie in one pipe without big jump on chord length. III Fixed problem with extremaPC with too close knot distribution to [minParam, maxParam] borders. IV ApproxInt_Approx.gxx New division criteria in intersection approximator. III Test case Test cases update to the new behavior. Test case for CR21564 Correction of test cases for issue CR21564 --- src/ApproxInt/ApproxInt_Approx.gxx | 112 +++++++---- src/BRepApprox/BRepApprox_Approx.hxx | 3 + src/Extrema/Extrema_GExtPC.gxx | 8 +- src/GeomInt/GeomInt_WLApprox.hxx | 5 +- src/IntPatch/IntPatch_RstInt.cxx | 52 +++-- src/IntTools/IntTools_FaceFace.cxx | 290 +++++++++++++++++++++++++-- tests/boolean/bsection/R9 | 2 +- tests/bugs/modalg_1/buc60532_2 | 1 + tests/bugs/modalg_1/buc60555_1 | 2 +- tests/bugs/modalg_1/buc60555_2 | 2 +- tests/bugs/modalg_1/buc60555_3 | 8 +- tests/bugs/modalg_2/bug22557 | 3 + tests/bugs/modalg_4/bug697_2 | 2 +- tests/bugs/modalg_4/bug697_4 | 2 +- tests/bugs/modalg_4/bug697_7 | 2 +- tests/bugs/modalg_4/bug697_8 | 2 +- tests/bugs/modalg_4/bug770 | 1 - tests/bugs/modalg_5/bug21564 | 61 ++++++ tests/bugs/modalg_5/bug23884 | 2 +- tests/bugs/modalg_5/bug24585_1 | 2 +- tests/bugs/modalg_5/bug24612 | 2 +- tests/bugs/modalg_5/bug24915 | 7 + tests/bugs/modalg_6/bug26310_4 | 5 - tests/offset/faces_type_i/M2 | 4 - 24 files changed, 481 insertions(+), 99 deletions(-) create mode 100644 tests/bugs/modalg_5/bug21564 diff --git a/src/ApproxInt/ApproxInt_Approx.gxx b/src/ApproxInt/ApproxInt_Approx.gxx index 6b90d71292..6c40c6d163 100644 --- a/src/ApproxInt/ApproxInt_Approx.gxx +++ b/src/ApproxInt/ApproxInt_Approx.gxx @@ -332,13 +332,16 @@ void ApproxInt_Approx::Perform(const Handle(TheWLine)& theline, nbmc++) { myBezToBSpl.Append(myComputeLineBezier.Value(nbmc)); } - if(imaxPoint(theMinIdx).Value().SquareDistance( + theline->Point(theMinIdx + 1).Value()); + + for(Standard_Integer anIdx = theMinIdx + 1; anIdx < theMaxIdx - 1; anIdx++) + { + Standard_Real aNextDist = theline->Point(anIdx).Value().SquareDistance( + theline->Point(anIdx + 1).Value()); + Standard_Real aCoeff = Min (aNextDist, aDist) / Max (aNextDist, aDist); + + // + if (aCoeff < aLimitMaxCoeff && // Base criteria. + aNextDist > aDist && // Step increasing. + aNextDist > aNullCoeff && // Avoid separation in case of too small step. + aDist > aNullCoeff) // Usually found when purger not invoked (blend). + { + return anIdx; + } + aDist = aNextDist; + } + return theMaxIdx; +} diff --git a/src/BRepApprox/BRepApprox_Approx.hxx b/src/BRepApprox/BRepApprox_Approx.hxx index 9b03e23118..c3c5bbd7e2 100644 --- a/src/BRepApprox/BRepApprox_Approx.hxx +++ b/src/BRepApprox/BRepApprox_Approx.hxx @@ -90,6 +90,9 @@ protected: private: + Standard_EXPORT Standard_Integer CorrectFinishIdx(const Standard_Integer theMinIdx, + const Standard_Integer theMaxIdx, + const Handle(BRepApprox_ApproxLine)& theline); Standard_EXPORT void Perform (const BRepAdaptor_Surface& Surf1, const IntSurf_Quadric& Surf2, const Handle(BRepApprox_ApproxLine)& aLine, const Standard_Boolean ApproxXYZ, const Standard_Boolean ApproxU1V1, const Standard_Boolean ApproxU2V2, const Standard_Integer indicemin, const Standard_Integer indicemax); diff --git a/src/Extrema/Extrema_GExtPC.gxx b/src/Extrema/Extrema_GExtPC.gxx index 59002f4f38..d931d9e3e0 100644 --- a/src/Extrema/Extrema_GExtPC.gxx +++ b/src/Extrema/Extrema_GExtPC.gxx @@ -105,12 +105,14 @@ void Extrema_GExtPC::Perform(const ThePoint& P) // Workaround to work with: // blend, where knots may be moved from param space.
