Implementation of the method for simplification of the result of Boolean Operation on the API level.
The method BRepAlgoAPI_BuilderAlgo::SimplifyResult has been added, so the derived classes such as BooleanOpeation and Splitter can also use this method.
The result shape simplification should be called after the operation is done. The simplification is performed by the means of ShapeUpgrade_UnifySameDomain algorithm.
Draw command "bsimplify" has been added to control the simplification options.
Documentation for new functionality and draw commands controlling the options of Boolean operations.
Test cases for the new functionality.
Side-effect change:
The algorithms in Boolean component have been changed to use the BRepTools_History as a History tool.
Now it became possible to disable the collection of shapes modifications during Boolean Operations, which may be useful for performance sake (in draw the option is controlled by *setfillhistory* command).
Draw command "unifysamedom" has been changed to accept the angular tolerance in degrees instead of radians.
All occurrences of Standard_EXPORT attached to inline methods in OCCT code are eliminated.
Some unused classes and C++ files producing no code are deleted.
Prevent modification of the input shapes in destructive mode in case their sub-shapes have not been modified:
1. Prevent edge splitting for the pave blocks with old vertices if it is possible to use the existing edge (*BOPAlgo_PaveFiller::MakeSplitEdges*);
2. Prevent creation of the new containers (WIRES/SHELLS/COMPSOLIDS) if non of its parts have been modified (*BOPAlgo_Builder::FillImagesContainer*);
3. Prevent creation of the new face if non of its wires have been modified (*BOPAlgo_Builder::FillImagesFaces*);
4. If possible, use the original face to be the representative for the group of SD faces (*BOPAlgo_Builder::FillSameDomainFaces*).
Cosmetic changes:
1. Documentation of the *BOPAlgo_Builder* class.
2. Making simple methods of the *BOPAlgo_Builder* class inline.
3. Getting rid of the *BOPAlgo_Builder::mySplits* field as it is excessive. *BOPAlgo_Builder::myImages* can be used instead.
3. Moving the Check Inverted option from *BOPAlgo_Options* to *BOPAlgo_Builder*.

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&)
The macros Status, Convex, Opposite, FillSolid (coming from X11 headers)
are now undefined in place of definition of methods with same name in OCCT headers.
The usage of variables with name Status is now avoided.
GL_GLEXT_LEGACY is now defined only if not already defined.
The macros AddPrinter (coming from WinAPI headers) is now undefined
within Message_Messenger class definition having method with the same name.
CurrentDirectory macro is now undefined in OSD_Process.hxx.
1. Removal of the traces of the usage of old Boolean operations in BRepFeat package.
2. The DRAW commands *fubl* and *cubl* based on old Boolean operations have been removed.
The alternative for these commands are the commands *bfuseblend* and *bcutblend* respectively.
The last two commands are based on the modern Boolean operations.
3. The DRAW command *ksection* based on old Boolean operations has been removed.
The command *bsection* should be used as alternative.
Test cases which have been using the *ksection* command have been modified to use the *bsection* command.
4. The class QANewBRepNaming_BooleanOperation has been modified to use modern Boolean operations.
The class QANewBRepNaming_BooleanOperation has been removed as not used.
The class QANewBRepNaming_BooleanOperationFeat has been renamed to QANewBRepNaming_BooleanOperation as it has nothing to do with Feat algorithm.
1. The algorithm BOPAlgo_ShellSplitter has been improved for the cases with multi-connected edges
to produce as many shells as possible from the given input faces.
2. Building tool prism in BRepFeat_MakePrism has been changed in order to avoid self-intersections
in the cases when the limiting faces are intersecting.
3. Test cases for the issue.
4. Test cases boolean/bcut_complex/N9 and boolean/gdml_private/ZH3 are improvements.
5. Test cases boolean/volumemaker/C5 and boolean/volumemaker/C6 has been marked as BAD due to found problem in intersection algorithm.
The results in these cases obtained on the branch are better than on master, but still not complete.
Adjusting test case bugs/moddata_2/bug469 for its current behavior.
Macro NO_CXX_EXCEPTION was removed from code.
Method Raise() was replaced by explicit throw statement.
Method Standard_Failure::Caught() was replaced by normal C++mechanism of exception transfer.
Method Standard_Failure::Caught() is deprecated now.
Eliminated empty constructors.
Updated samples.
Eliminate empty method ChangeValue from NCollection_Map class.
Removed not operable methods from NCollection classes.
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.
The new method has been added in the class BRepFeat_SplitShape for addition of the sequence of the splitting edges or wires for the whole initial shape without specification of the edge->face, edge->edge mapping.
The procedure of collecting wires has been corrected so as not to take into account the distance in 2D space between adjacent edges having a common vertex.
New category of tests "bugs/splitshape" has been added to non-regression data base.
Test cases for issue CR27520
Remove compilation warnings.
Add dependence of TKFeat on TKShHealing in EXTERNLIB in order to build with genproj.
Method BRepLib::EncodeRegularity() is improved to set regularity GeomAbs_CN for edges lying on the same-domain surfaces (where derivatives on both surfaces are equal in all points).
DRAW command getedgeregularity is added to query regularity of the edge on specified faces.
DRAW command edgeregul is removed (this functionality is provided by command encoderegularity).
Added tests: bugs modalg_6 bug27272, bug27383_1, bug27383_2
Correction of shape name in test case for issue CR27272
Method DownCast() is made template, to be available only when argument is actually a pointer or handle to a base class.
For compatibility with existing code, method DownCast() that can be used for the same type, derived, or unrelated class (i.e. where there is no actual down casting) is still available, its use shall cause "deprecated" compiler warning.
OCCT code is updated to remove meaningless DownCast()s; a few places where DownCast() was used with argument of unrelated type are corrected.
DRAW command QAHandleCast is removed (it was useful only during redesign of handles).
firsthole / holend / hole commands have been corrected.
Now they work correctly on the planar faces
Also some commented code have been deleted
Temporary update for backward compatibility with WOK
Clean-up in code causing warnings when OCCT_DEBUG is enabled
Minor corrections:
- new compiler warnings on VC++ 14
- rename of "PPC" variables that are said to caused conflicts on PowerPC
- removal of unused header TopOpeBRep/TopOpeBRep_tools.hxx
- Class OSD_EnvironmentIterator is removed (not used, and would definitely fail under Windows if tried)
- Methods UserId() and GroupId() removed from OSD_FileNode (cannot be made portable, as there is no integer IDs of user and group on Windows)
- Draw_ProgressIndicator corrected to properly pass address via Tcl
- OSD_File.cxx: local function is refactored to avoid senseless encoding / decoding of results
- OSD_Process::UserId() method removed, as it cannot be made cross-platform (no integer IDs on Windows)
- OSD_Thread: use WinAPI conversion functions to avoid warnings
- OSD_WNT.cxx: recursion counter passed via function argument instead of TLS
- TDF_LabelMapHasher revised to use correct hasher function for an address
Adaptations for compiling with GCC 4.7 and 4.8:
- Construction semantics is used for Handle objects being initialized by const Handle objects of derived type, to avoid overload resolution error in GCC 4.7.
- Missing includes added.
- Fixed bugs related to misuse of direct casts of handle.
- Eliminate CLang warnings on uninitialized and unused variables, functions, and expressions
Automatic upgrade of OCCT code by command "occt_upgrade . -nocdl":
- WOK-generated header files from inc and sources from drv are moved to src
- CDL files removed
- All packages are converted to nocdlpack
Code corrected to avoid ambiguous situations due to changed implementation of Handle (overloaded methods accepting handles of different types).
In Adaptor3d_CurveOnSurface added method Load() with two parameters, allowing to avoid ambiguity of cast of handles when calling separate methods Load() for curve and surface, replacing by single call.
In DrawTrSurf and IGESData_IGESWriter, template variants of methods Set() and Send(), respectively, are added to avoid ambiguity when these methods are called with handles to derived types (using SFINAE).
In NCollection_DefineHSequence, method Append() accepting handle to another HSequence is made template, to be available only if argument has compatible type.
Automatic update by command "occt_upgrade . -downcast"
C-style cast of Handle to that of derived type (now illegal) is replaced by call to DownCast()
Const reference local variables of Handle type initialized by result of DownCast are replaced by normal variables.
1. Using of the "Closed" flag was unified:
a) this flag is applicable for TopoDS_Wire and TopoDS_Shell only, because these entities may hedge an area in 2D space or a volume in 3D space correspondingly;
b) other types of TopoDS shapes are passing over this flag;
c) changing of this flag should be controlled by high-level algorithms (not BRep_Builder).
2. Implemented verification of the closedness of edges. An edge is closed if and only if its first and last vertices are the same.
3. Test cases were changed according to new behavior.
Macros ending on "DEB" are replaced by OCCT_DEBUG across OCCT code; new macros described in documentation.
Macros starting with DEB are changed to start with "OCCT_DEBUG_".
Some code cleaned.
Method BRep_Tool::IsClosed() extended to analyze closure of wires in addition to shells and solids.
External and Internal edges and vertices are ignored in this check.
Analysis of compounds is disabled.
Update of flag Closed according to actual state is added in most places where new shells are constructed.
