When fuzzy option is in force prevent increasing tolerance of input shapes. Instead pass increased by fuzzy value the tolerances of sub-shapes everywhere where it is needed by intersection algorithms. The following changes in API have been made: - The methods SetFuzzyValue and FuzzyValue have been moved from the classes BOPAlgo_ArgumentAnalyzer, BOPAlgo_Builder, and BOPAlgo_PaveFiller to the base class BOPAlgo_Algo. - The public method BOPDS_DS::VerticesOnIn has been renamed to SubShapesOnIn, and the new output parameter theCommonPB has been added. - In BOPTools_AlgoTools, a new argument "theFuzzyValue" has been added in the methods ComputeVV and AreFacesSameDomain. - In IntTools_Context, a new argument "theFuzzyValue" has been added in the methods ComputeVE and ComputeVF. - The methods SetFuzzyValue and FuzzyValue have been added in the classes IntTools_EdgeEdge, IntTools_FaceFace. - In the class IntTools_EdgeFace, the methods SetTolE, SetTolF, TolE, TolF have been removed, and the methods SetFuzzyValue, FuzzyValue have been added. - The new argument "theTol" has been added in the method IntTools_WLineTool::DecompositionOfWLine. Some improvements in algorithms have been made during fighting with regressions: - Correct initialization of pave blocks for degenerated edges. - In BOPAlgo_PaveFiller::MakeBlocks(), filter out paves on intersection curve that were put on the curve accidentally due to wide range of E-F intersection vertex. - In the method IntTools_Tools::ComputeTolerance the margin added to the computed tolerance has been increased up to 0.001%. - The method BOPAlgo_PaveFiller::PutPaveOnCurve has been corrected in order to use the original vertex tolerance instead of the value increased during putting it on other curves. - The new method BOPDS_PaveBlock::RemoveExtPave has been added. - The vertex tolerance computation in BOPTools_AlgoTools::CorrectCurveOnSurface has been improved, taking into account intersection segments between p-curves (to avoid regression on "bugs modalg_6 bug22794"). - Improve IsExistingPaveBlock to make more stable catching of coincidence of common block with section curve (against regression "bugs modalg_4 bug697_2" on Linux). Test case for the bug has been added. The following test cases have been updated as improvements: boolean gdml_private ZH2 ZI7 ZJ7 boolean volumemaker C4 The test case bugs/modalg_4/pro19653 has been corrected to make it stable. See comment inside the script for details. The test case bugs/modalg_6/bug25880 has been corrected to suppress wrong bfuse commands. The test bugs/modalg_6/bug26954_3 has been corrected to compare the result with more precise reference value. The "faulty" TODO in boolean/volumemaker/A8 has been made actual for Linux as well. //Eliminate compilation error on Linux.
