0029711: General Fuse operation produces invalid result The following improvements have been introduced in Boolean Operations algorithm s: 1. UBTree is replaced with EBTree in Boolean operations to be able to add/remove elements into the tree of bounding boxes. 2. Repeated (nested) intersection of sub-shapes is performed with argument vertices whose tolerances increased during the operation. 3. The algorithms of Edge/Edge and Edge/Face intersection have been improved for the cases when the intersection point is located close to the edge boundaries . 4. New procedure has been implemented to ensure forced creation of Edge/Face common blocks in cases when the edge is really close to the face. 5. Post-processing of Face/Face intersection results has been improved. 6. Extension of the planar faces for Plane/Plane intersection is avoided. 7. Builder Face now better classifies potentially internal edges relatively to new faces with filtering by bounding boxes. Side effect changes: 1. IntTools_ShrunkRange now keeps the length of the valid range of the edge. 2. The method BOPDS_DS::UpdateEdgeTolerance() has been removed as unused (replaced by the BOPAlgo_PaveFiller::UpdateEdgeTolerance()). Test case for the issue 0029900. Test case for the issue 0029711. Adjustments of the existing test cases. Avoid using uninitialized variables.

0028599: Replacement of old Boolean operations with new ones in BRepProj_Projection algorithm The usage of *BRepAlgo_Section* has been replaced with the usage of *BRepAlgoAPI_Section* in *BRepProj_Projection* algorithm. The TODO statements have been removed from the failing test case in the "prj" grid as they are working correctly now. The following changes have been made to improve the performance *BRepAlgoAPI_Section*: 1. Revision of the *IntPolyh_Intersection* class to avoid repeated calculation of the deflection of the same triangulation. 2. Small revision of the Edge/Face intersection algorithm to perform Extrema computation on the whole intersection range of the edge instead of discrete ranges. 3. Implementation of the extrema computation for the Circle and Sphere. 4. Correct computation of the parameter of the point on the Circle.

0025609: Clean up the duplicate classes in TKBO project 1. The package BOPCol has been fully removed: - *BOPCol_BaseAllocator* is replaced with *Handle(NCollection_BaseAllocator)*; - *BOPCol_BoxBndTree* is replaced with *BOPTools_BoxBndTree*; - *BOPCol_Box2DBndTree* is removed as unused; - *BOPCol_DataMapOfIntegerInteger* is replaced with *TColStd_DataMapOfIntegerInteger*; - *BOPCol_DataMapOfIntegerListOfInteger* is replaced with *TColStd_DataMapOfIntegerListOfInteger*; - *BOPCol_DataMapOfIntegerListOfShape* is replaced with *TopTools_DataMapOfIntegerListOfShape*; - *BOPCol_DataMapOfIntegerMapOfInteger.hxx* is removed as unused; - *BOPCol_DataMapOfIntegerReal* is replaced with *TColStd_DataMapOfIntegerReal*; - *BOPCol_DataMapOfIntegerShape* is replaced with *TopTools_DataMapOfIntegerShape*; - *BOPCol_DataMapOfShapeBox* is replaced with *TopTools_DataMapOfShapeBox*; - *BOPCol_DataMapOfShapeInteger* is replaced with *TopTools_DataMapOfShapeInteger*; - *BOPCol_DataMapOfShapeListOfShape* is replaced with *TopTools_DataMapOfShapeListOfShape*; - *BOPCol_DataMapOfShapeReal* is replaced with *TopTools_DataMapOfShapeReal*; - *BOPCol_DataMapOfShapeShape* is replaced with *TopTools_DataMapOfShapeShape*; - *BOPCol_DataMapOfTransientAddress* is removed as unused; - *BOPCol_IndexedDataMapOfIntegerListOfInteger* is removed as unused; - *BOPCol_IndexedDataMapOfShapeBox* is removed as unused; - *BOPCol_IndexedDataMapOfShapeInteger* is removed as unused; - *BOPCol_IndexedDataMapOfShapeListOfShape* is replaced with *TopTools_IndexedDataMapOfShapeListOfShape*; - *BOPCol_IndexedDataMapOfShapeReal* is removed as unused; - *BOPCol_IndexedDataMapOfShapeShape* is replaced with *TopTools_IndexedDataMapOfShapeShape*; - *BOPCol_IndexedMapOfInteger* is replaced with *TColStd_IndexedMapOfInteger*; - *BOPCol_IndexedMapOfOrientedShape* is replaced with *TopTools_IndexedMapOfOrientedShape*; - *BOPCol_IndexedMapOfShape* is replaced with *TopTools_IndexedMapOfShape*; - *BOPCol_ListOfInteger* is replaced with *TColStd_ListOfInteger*; - *BOPCol_ListOfListOfShape* is replaced with *TopTools_ListOfListOfShape*; - *BOPCol_ListOfShape* is replaced with *TopTools_ListOfShape*; - *BOPCol_MapOfInteger* is replaced with *TColStd_MapOfInteger*; - *BOPCol_MapOfOrientedShape* is replaced with *TopTools_MapOfOrientedShape*; - *BOPCol_MapOfShape* is replaced with *TopTools_MapOfShape*; - *BOPCol_PListOfInteger* is removed as unused; - *BOPCol_PInteger* is removed as unused - *BOPCol_SequenceOfPnt2d* is replaced with *TColgp_SequenceOfPnt2d*; - *BOPCol_SequenceOfReal* is replaced with *TColStd_SequenceOfReal*; - *BOPCol_SequenceOfShape* is replaced with *TopTools_SequenceOfShape*; - *BOPCol_Parallel* is replaced with *BOPTools_Parallel*; - *BOPCol_NCVector* is replaced with *NCollection_Vector*; 2.

The container *BiTgte_DataMapOfShapeBox* is replaced with *TopTools_DataMapOfShapeBox*; 5. The class *BOPTools* has been removed as duplicate of the class *TopExp*;

0029073: Regression: General Cut produces invalid shape Boolean Operations: 1. Face/Face intersection post treatment - Unify vertices put on the section curves, which were rejected as existing ones, with the vertices of edges by which these section curves have been rejected. 2. Extend Warnings Reporting system of Boolean operations with the new warnings: - BOPAlgo_AlertIntersectionOfPairOfShapesFailed - to be added when the intersection of pair of sub-shapes of the arguments has failed; - BOPAlgo_AlertBuildingPCurveFailed - to be added when the building of the 2D curve of the edge on face has failed; - BOPAlgo_AlertAcquiredSelfIntersection - to be added when the positioning and tolerances of the arguments leads to creation of self-interfered shapes. These new warnings allow completing the operation even if intersection of some of the sub-shapes or building of some of the PCurves has failed. Moreover, they allow getting the pairs of sub-shapes on which the intersection/projection has failed, providing the user ability to analyze the intersection results. Note that if some of these warnings appear, the result of the operation should be carefully analyzed for validity. 3. Print messages for the Warnings/Errors met during checking of the shape on self-intersection ("bopcheck" command).

0028786: Refactoring of the Warning/Error reporting system of Boolean Operations Algorithm 0. Basic tools for defining classes representing alerts (errors, warnings etc.) and collecting them during execution of algorithms are added in Message package. 1. Refactoring of the Error/Warning reporting system of the algorithms in Boolean Component. To dump the description of the Error/Warning status of the algorithm the DumpErrors/DumpWarnings method should be called. Also, the methods GerErrorMsg(int Error) and GetWarningMsg(int Warning) have been implemented to get the description for the given Error/Warning. All Error/Warning statuses are now listed in the enumeration ErrorStatusEnum/WarningStatusEnum of the algorithm. It is also possible to get the shapes for which the warning has been set by using the method GetWarningShapes(). 2. The new class BOPAlgo_Options has been created to unify the options of the BOPAlgo_* and BRepAlgoAPI* algorithms. 3. The new checks across the algorithms have been added to detect and report errors and warnings. 4. Test cases boolean bopcut_complex B9 E1 E5 E8 boolean bopfuse_complex B4 B5 C9 D1 D4 D5 D6 D7 have been rewritten to use Cells Builder algorithm instead of Boolean Operations algorithm, because latter always returns error "Unsupported Boolean operation" for these cases. 5. New chapter has been added in the user guide for Boolean Operations - Error / Warning reporting system. 6. Added comment to NCollection_List::Remove(Iterator&)

0028775: Code duplication removal across the BOPAlgo_PaveFiller algorithm The methods PerformVerticesEE() and PerformVerticesEF() of the class BOPAlgo_PaveFiller have been replaced with the new PerformNewVertices() method. While splitting the Pave Blocks with extra paves, check that the new Pave Blocks have the valid intersection range. If the new Pave Block does not have such range do not create it and unify its vertices making SD vertex. Re-computation of the Shrunk Data for the modified Pave Blocks. The new method BOPDS_DS::IsValidShrunkData(const Handle(BOPDS_PaveBlock)& thePB) has been implemented to check that the Shrunk Data of the Pave Block is still valid. It may become invalid in case the tolerance values of the vertices of the Pave Block have been modified. The test case bugs/modalg_6/bug27448_2 has been marked as BAD, because it uses the invalid shapes as inputs for BOP. Test cases for the issue 0028690.

0028284: Avoid classification of sub-shapes of arguments of BOPs relatively solids during Intersection phase 1. The methods PerformVZ, PerformEZ, PerformFZ and PerformZZ have been transferred from BOPAlgo_PaveFiller to BOPAlgo_CheckerSI class to perform intersection of sub-shapes with solids only in self-intersection mode. 2. The checks for solids built from the same (shared) faces have been added into methods building the result of Boolean operations - BOPAlgo_BOP::BuildRC() and BOPAlgo_BOP::BuildSolid(). 3. Since the NonDestructive mode is now natively supported by the BOPAlgo_PaveFiller the methods providing the support of this mode by CheckerSI (BOPAlgo_CheckerSI::PrepareCopy() and BOPAlgo_CheckerSI::PostTreatCopy()) are not needed and have been removed. 4. The pairs of sub-shapes with interfering bounding boxes are now sorted before real intersection to guarantee the constant order of intersection of sub-shapes and produce more stable result. The class BOPDS_PassKey has been replaced with simpler class BOPDS_Pair. 5. The class BOPDS_SubIterator has been refactored. 6. Test cases for the issue. 7. Adjustment of the test case boolean volumemaker D2.

0028165: Improve performance of Boolean Operations 1. Unification of the usage of the BRepAdaptor_Surface in Boolean Operations algorithm. For each face when it is necessary the Adaptor is initialized only once and stored in Context. For that purpose the new IntTools_Context::SurfaceAdaptor(const TopoDS_Face&) method has been implemented. To provide possibility to take the Adaptor from the context, the context has been added as a parameter in following methods: BOPTools_AlgoTools::MakePCurve() BOPTools_AlgoTools::Sence() BOPTools_AlgoTools2D::BuildPCurveForEdgeOnFace() BOPTools_AlgoTools2D::PointOnSurface BOPTools_AlgoTools2D::CurveOnSurface BOPTools_AlgoTools2D::AdjustPCurveOnFace BOPTools_AlgoTools2D::Make2D BOPTools_AlgoTools2D::MakePCurveOnFace BOPTools_AlgoTools3D::GetNormalToFaceOnEdge It is also possible now to pass the context into BOPAlgo_WireSplitter algorithm. Also, the new IntTools_Context::UVBounds(const TopoDS_Face&) method has been implemented to get the UV bounds of a face. 2. Additional improvement is a calculation of reduced intersection range only for the intersection type VERTEX during computation of Edge/Face interference. 3. The methods IntTools_EdgeFace::Prepare() and IntTools_EdgeFace::FindProjectableRoot() and the fields IntTools_EdgeFace::myProjectableRanges and IntTools_EdgeFace::myFClass2d have been removed as obsolete. 4. Test cases for the issue.

0027878: Development of the Gluing operations based on the new Boolean component The Gluing operation is an additional option for the algorithms in the Boolean Component such as General Fuse, Boolean operations, Section operation, Maker Volume and Cells Builder algorithms. The Gluing options have been designed to speed up the computation of the interference among arguments of the operations on special cases, in which the arguments may be overlapping but do not have real intersections between their sub-shapes. This option cannot be used on the shapes having real intersections, like intersection vertex between edges, or intersection vertex between edge and a face or intersection line between faces. The Gluing option is an enumeration implemented in BOPAlgo_GlueEnum.hxx. There are following items in the enum: * BOPAlgo_GlueOff - default value for the algorithms, Gluing is switched off; * BOPAlgo_GlueShift - Glue option for shapes with partial coincidence; * BOPAlgo_GlueFull - Glue option for shapes with full coincidence. For setting the Gluing options for the algorithm it is just necessary to call the SetGlue(BOPAlgo_GlueEnum) method with appropriate Glue value. For using this option in DRAW the command bglue has been implemented: * 0 - default value, Gluing is off; * 1 - for partial coincidence; * 2 - for full coincidence Elimination of the warnings.

0026738: Make Boolean operations safely treating arguments when running with fuzzy option 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.

0027448: BOPTools_AlgoTools::IsMicroEdge does not correspond to shape validity criteria 1. IntTools_ShrunkRange::Perform The algorithm of building shrunk range on the edge has been redesigned to make this range as big as possible. By new definition it has to have the length not less than Precision::Confusion(). Although, the possibility of splitting of the edge has been taken into account. If it is impossible to put vertex on edge in such a way that the tolerance spheres of the edge's vertices do not intersect the tolerance sphere of the putting vertex the edge cannot be split. This possibility is saved in the new field IntTools_ShrunkRange::myIsSplittable. It can be checked by the corresponding method IntTools_ShrunkRange::IsSplittable(). It returns TRUE if the shrunk range is computed successfully and it has the length more than the value of sum of two tolerance values of the edge (for putting vertex, as its tolerance should not be less than the tolerance value of edge) and two Precision::Confusion() values (to make two new edges valid by Shape validity criteria). IntTools_ShrunkRange::myErrorStatus and IntTools_ShrunkRange::ErrorStatus() have been replaced by the IntTools_ShrunkRange::myIsDone and IntTools_ShrunkRange::IsDone(). IntTools_ShrunkRange::IsDone() returns TRUE if the shrunk range has been computed and it has length more than Precision::Confusion(). All computations of the parameters are performed using the GCPnts_AbscissaPoint, but if AbscissaPoint is unable to compute the parameters the Resolution of the curve is used. 2. Boolean Operations algorithm now partially works with the edges that cannot be split or does not have the ShrunkData at all (previously such edges have been considered as micro and just ignored). If by the result of some intersection such edges should be split, i.e. the intersection vertex should be created, the algorithm just ignores them and no vertex is created. But if such edges coincide with other shapes (other edges or faces) the algorithm uses them for creation of common blocks. The information of the possibility for the edges to be split is saved in its PaveBlocks, in the new BOPDS_PaveBlock::myIsSplittable field. It can be retrieved by the BOPDS_PaveBlock::IsSplittable() or BOPDS_PaveBlock::ShrunkData(), but these methods make sense only after filling of the shrunk data for the pave block. BOPTools_AlgoTools::IsMicroEdge() has an additional parameter that defines whether it is necessary to take into account the possibility for the edge to be split or not. By default it is set to TRUE, i.e. by default the edge will be considered as micro even if the shrunk range is computed, but it is too short for the edge to be split. 3. BOPAlgo_PaveFiller::PerformEF To avoid creation of too close intersection vertices the intersection ranges of the edges participating in Edge/Face intersections are reduced taking into account the common ranges computed during Edge/Edge intersections. Thus, the Edge/Face intersection vertex is not created if it gets into a common range of the Edge/Edge intersection between that edge and one of the face's edges. The tolerance value of Edge/Edge intersection vertex is increased to reach the Edge/Face intersection. 4. Unification of the vertices of the section edges considered as micro edges. If by the result of some Face/Face intersection the section edge is considered as micro edge, the vertices of this edge will be united and the edge itself will be removed. 5. Test cases for the issues. 6. Adjusting test cases for issue CR27448.

0026132: Invalid result of boolean operation 1. The procedures for check of coincidence between Edge-Edge and Edge-Face have been added. These methods are used instead of searching interferences between corresponding sub-shapes. In most cases (including case for this issue), new methods are more reliable and faster than intersections. However, its use should be avoided in case when the edge is not coincide with edge/face of another argument evidently (e.g. if edge vertices are not in another edge/face). 2. Interface of both IntTools_EdgeFace and IntTools_EdgeEdge has been changed (adding/deleted some field and methods). Some test cases have been corrected in accordance with their new behavior. Test case for issue CR26132.

0026619: Tolerances of operands are modified using bop 0026796: The result of General Fuse operation is self-intersecting shape The fix forces creation of new sub-shapes (vertex, edge) when the tolerance of some sub-shape of an argument is to be increased. This new behavior is turned off by default. It can be turned on using two ways: 1) Setting 'locking' flag of the arguments. 2) Calling the method SetNonDestructive(Standard_True) of the API classes. Various bug fixes in the algorithm: - Compute correct tolerance values for intersections of type Line/Line, Line/Plane, Plane/Plane. - In case of Line/Plane intersection check if line's vertices lie on the plane. - Do not allow decreasing of the tolerance value of the Line/Line intersection vertex. - In IntTools_EdgeEdge, call the method FindParameters with proper 3D tolerance of the curve. - Force making copy of a degenerated edge if its vertex is touched but no 2D intersection with other curves is found. - Remove pave blocks both ends of which became referring to the same vertex after vertices substitution. - Avoid exception in IntTools_Context::IsVertexOnLine if Extrema is not done. - Reduce tolerance of vertex/edge using actual distances to interfered shapes if it was increased due to line/line, line/plane, or plane/plane small intersection angle. - Update tolerance of edges to reach all representations in a common block. - In V-E intersections, check if a vertex hits beyond shrunk range, in such case create V-V interference. - Do not put a section edge to the result if it becomes to be a micro edge after updating its vertex. - Correctly make vertices same-domain during the work of MakeBlocks. - Decrease shrunk range at least on a Precision::Confusion() in addition to vertex tolerance. - Add Confusion to bounding boxes of new shapes in DS - Add tolerance Precision::Confusion() to compare distances of touching cases to fix regressions.
