d03c08988c 0021264: Modeling Algorithms - Progress indicator for Boolean operations
Update BOP commands to use progress indicator
Deleted wrong usage of progress indicator from bop operations
Added UserBreak() method to break execution boolean operation if progress indicator is used
Added method AnalyzeProgress() to calculate steps of progress indicator
Introduce BOPAlgo_ParallelAlgo which has myRange as a field to be used in parallel vector.
Provide suitable way of keeping the progress steps of operations.
Give meaningful names to progress scopes.
Propagate progress indicator into deeper methods of BOA.
Add progress indicator to BOPAlgo_BuilderFace and BOPAlgo_WireSplitter, BOPAlgo_BuilderSolid and BOPAlgo_ShellSplitter

948fe6ca88 0028747: Incorrect result of the section operation after edge refinement
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.

944768d277 0029312: Using OBB to speed up Boolean Operations
1. Implementation of the user-defined option for usage of Oriented Bounding Boxes (OBB) in Boolean Operations for additional filtering (rejection) of selected for intersection pairs of sub-shapes.

By default the usage of OBB is turned off.
To enable/disable its usage the method SetUseOBB(flag) should be used. This method is available for all operations in Boolean Component.
To enable/disable it in draw the command "buseobb 0/1" should be used. Note, that this will affect all subsequent operations.

The OBB for the shapes are built by first necessity and stored into operation context (IntTools_Context).

2. Usage of the OBB in some test cases.

98b3765966 0029237: Improve performance of Boolean Operations
In order to improve performance of Boolean Operations on the relatively fast cases the following improvements have been made:
1. Initialization of the FaceInfo information for the faces participating in Face/Face interference, even when the gluing is ON, to take into account intersection of their sub-shapes.
2. Code simplification & duplication removal - the methods BOPAlgo_ShellSplitter::MakeConnexityBlocks and BOPAlgo_WireSplitter::MakeConnexityBlocks have been unified into BOPTools_AlgoTools::MakeConnexityBlocks.
3. Avoid unnecessary bounding box computation for solids during DS initialization. The bounding boxes for solids will be computed during the building stage to find faces located inside solids.
   For the shape self-interference check (performed by the BOPAlgo_CheckerSI), the bounding box is still computed, as it is necessary to resolve Shape/Solid intersections.
4. Use only three sample points to check coincidence of line and plane.
5. Perform necessity of planes intersection only when the gluing is off.
6. Avoid repeated initialization of 2D classifier while building splits of the faces.
7. Post treat stage:
7.1. Method CorrectWires: Save edge's data (PCurve, parameter of the vertex, range) to avoid its recalculation.
7.2. Method CheckEdge: While checking vertices on edges avoid unnecessary calculation of their location.
8. Provide possibility to disable the classification of the input solids on the inverted status (to be the holes in the space).
9. Avoid building of bounding boxes for faces/solids during splitting of the input arguments for their classification relatively hole faces/shells if there are no holes created.
10. Avoid rebuilding of the faces/solids from arguments which does not acquire any inside parts from other arguments during the operation by using their draft versions as their splits.

Test cases for the issue.
Correction of the test cases boolean gdml_public A9 and bugs modalg_7 bug28485 as they are improvements.
Additional test case for the issue #28485 as it is fixed by the current changes.

33ba856502 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&)

c58055adeb 0026874: Implementation of the Partition operator in OCCT
1. The partition operation allows splitting an arbitrary number of shapes of an arbitrary dimension
by other arbitrary shapes. The algorithm has been implemented in the class BOPAlgo_Splitter.

The API operator Splitter has been implemented in the class BRepAlgoAPI_Splitter.

2. The draw commands for usage the new algorithm have been implemented - bsplit and bapisplit.
The commands are identical, but one uses the BOPAlgo_Splitter, the other uses BRepAlgoAPI_Splitter.
Both commands should be used after Pave Filler is filled.

3. Test cases for the new algorithm.

4. Documentation has been updated.

Small corrections.
