From 4dcb416ea48583f4e3164faff1d889b06aad2fda Mon Sep 17 00:00:00 2001 From: eap Date: Mon, 27 Jun 2011 08:24:04 +0000 Subject: [PATCH] Author: Roman Lygin, roman.lygin@gmail.com fixS020 - Summary: Invalid computation of edge length on periodic curve leads to wrong tessellation - Detailed description: SMESH_Algo returns incorrect edge length (1e-08) for an edge lying beyond periodic curve range. Afterwards the number of segments is computed as ~ 1/lentgh and becomes 1.9M leading to running out of memory or failure to produce 2D mesh. - Reproducer: Try to mesh f-percrvedge.brep with 1D Wire Discretization and default MaxSize hypothesis. --- src/SMESH/SMESH_Algo.cxx | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/SMESH/SMESH_Algo.cxx b/src/SMESH/SMESH_Algo.cxx index 331f61127..1e864ad97 100644 --- a/src/SMESH/SMESH_Algo.cxx +++ b/src/SMESH/SMESH_Algo.cxx @@ -171,7 +171,7 @@ double SMESH_Algo::EdgeLength(const TopoDS_Edge & E) return 0; TopLoc_Location L; Handle(Geom_Curve) C = BRep_Tool::Curve(E, L, UMin, UMax); - GeomAdaptor_Curve AdaptCurve(C); + GeomAdaptor_Curve AdaptCurve(C, UMin, UMax); //range is important for periodic curves double length = GCPnts_AbscissaPoint::Length(AdaptCurve, UMin, UMax); return length; } -- 2.39.2
