Boolean Operations algorithm improvements:
1. To be able to add/remove elements into the tree of bounding boxes UBTree is replaced with EBTree in Boolean operations.
2. Perform repeated (nested) intersection of sub-shapes of the arguments with vertices which tolerances have been increased during the operation.
3. Edge/Edge and Edge/Face intersection point creation improvement for the cases when intersection point is located close to the edge's boundaries.
4. Forced Edge/Face intersection procedure to ensure common blocks creation.
5. Face/Face intersection post treatment stage improvements.
6. Avoid extension of the planar faces for Plane/Plane intersection.
7. Builder Face algorithm - improve classification of the potentially internal edges relatively new faces by adding filtering by bounding boxes.
Side effect changes:
1. IntTools_ShrunkRange is 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.
The regression caused by the patch for 0030534 has been eliminated. For that the method InsertWiresIntoFaces() has been corrected: the face to which a wire is added is first oriented as forward.
1. Add method TransformPCurves to ShapeUpgrade_UnifySameDomain - to rotate and translate existing pcurves instead of projecting.
2. Modify method ShapeUpgrade_UnifySameDomain::IntUnifyFaces - now it does not apply ShapeFix to new wires and new faces.
3. In the method UnifyEdges: add merging degenerated edges.
The reason of this problem is in wrong work of classifier algorithm (see the message ~0080992 to the issue #30354). Therefore, the algorithm of IntTools_FClass2d class has been improved. Namely, now orientation of the polygon is computed from area-criterion instead of angle. As result, some simplification of the method IntTools_FClass2d::Init(...) has been made.
<!break>
1. New constructor has been added to the class CSLib_Class2d. It allows applying TColgp_SequenceOfPnt2d.
2. DRAW-commands "addpolygonnode" and "polygonprops" have been created. They are covered by the test case "tests/geometry/2dpolygon/A1".
3. New method Poly::PolygonProperties(...) has been created. See help for detailed information.
4. New testgrid "lowalgos classifier" has been created.
The algorithm has been improved for the cases when the intersection line goes through the cone apex.
<!break>
1. All special points are put to the ALine forcefully (if they are true intersection point). Currently this step has not been implemented yet.
2. Now the tolerance of IntPatch_Point (put into ALine) is computed in order to cover the distance between it and the correspond ALine.
3. Test cases have been created.
4. Procedure of trimming IntAna_Curve has been improved.
5. Criterion when the discriminant of IntAna_Curve can be considered to be equal to 0 has been improved.
6. Methods IntAna_Curve::FindParameter(...) (and IntPatch_ALine::FindParameter(...)) currently returns list of all parameters corresponding the given point (IntAna_Curve can be self-interfered curve). Before the fix, this method always returned only one (randomly chosen) parameter.
7. Interfaces of the following methods have been changed: IntAna_Curve::FindParameter(...), IntPatch_ALine::FindParameter(...), IntPatch_ALine::ChangeVertex(...), IntPatch_SpecialPoints::AddPointOnUorVIso(...), IntPatch_SpecialPoints::AddSingularPole(...), IntPatch_WLineTool::ExtendTwoWLines().
8. Following methods have been added: IntAna_Quadric::SpecialPoints(...), IntPatch_ALineToWLine::GetSectionRadius(...), IntPatch_SpecialPoints::ProcessSphere(...), IntPatch_SpecialPoints::ProcessCone(...), IntPatch_SpecialPoints::GetTangentToIntLineForCone(...).

They are real IMPROVEMENTS. In the FIX (in compare with MASTER), section result between pairs of faces f2&f6 (C5), f3&f7 (C6) and f1&f5 (E7) is closed. Separated test cases have been created in order to focus on the problem with section. Bug #28503 has been fixed.
Correction in test cases.
Add history for subshapes of spine: edges and vertices. Each edge of spine generates a shell. Each vertex of spine generates a set of edges and, possibly, faces (in the case of Round Corner).
(cherry picked from commit fcad97e74bdd3a96f0467188f5468b70cb0e2c81)
Before the fix, small arc of circle returned as intersection result. It was connected with the fact that the circle always was limited in 0 and 2*PI points. Currently the bounds of the circle (retrieved as an intersection curve) are computed from the real domain of the arguments (there is not a snap to the fixed 0 and 2*PI points).
(cherry picked from commit 94783b5111cbefcedf4f6eae72e7cd3b78c7b13b)
BOPTools_AlgoTools::ComputeState - increase the chance of correct classification of the face relatively solid by classifying the point located inside that face instead of the point taken near the edge of that face.
Test case for the issue.
(cherry picked from commit 56062e13f2f4852de3904b5529aabc3ca78713ba)
Added protection against clash of attributes with the same GUID when more than one attribute of the same type but with different GUIDs are stored in the file.
If attribute with default GUID has already been read, then adding next empty attribute of the same type (done at start of its reading) will fail; in such case another attempt is made with Null GUID.
Information on replacement of CDM_MessageDriver by Message_Messenger is added in the upgrade guide.
This replacement is recorded as rename in upgrade.dat
- XCAFNoteObjects_NoteObject transfer object for note's auxiliary data was added. It contains the following fields:
text and attachment positions, note plane and tesselated presentation
- GetObject/SetObject methods were added to XCAFDoc_Note attribute. The following sub-labels were added to handle transfer object:
1 - text position
2 - note plane
3 - attachment point
4 - tesselated presentation
- documentation updated
Off-topic: procedure genproj now gives meaningful error message if new package is added but not listed in UDLIST
In the method STEPCAFControl_Reader::ExpandShell protection for case when entity ""Connected_Face_Set" contains not only "FACE" entities ( for example "VERTEX_POINT" entities) was added.
OpenGl_Structure::Render(), added missing check for disabled state of the plane.
vclipplane command has been extended with new option -setOverrideGlobal.
The API classes in the package BRepAlgo providing access to old Boolean operations (Fuse, Common, Cut, Section) are marked as deprecated.
Corresponding classes from the package BRepAlgoAPI should be used instead.
Problem is fixed by the fix for the issue #0028599 (porting of the BRepProj_Projection to modern Boolean Operations algorithm)
Thus, only test case is integrated here.
Introduced new method AIS_InteractiveContext::ClearDetected() allowing
to reset the list of detected objects and clear dynamically highlighted
entity under mouse cursor after previous AIS_InteractiveContext::MoveTo().
vmoveto command has been extended with new argument -reset.
- TNaming_UsedShapes is corrected to do not call methods of empty TopoDS_Shape
- TNaming_NamedShape is corrected to have not NULL TNaming_RefShape even if TopoDS_Shape is NULL(TNaming_Builder::Delete).
- DFBrowserPane presentation tree item for this is corrected in the same way and obsolete methods of processing SortedReferences are removed.
- AIS_InteractiveContex and VInspector_ViewModelHistory are set into VInspector_CallBack
- minor correction of displaySelectedPresentations () to Hide/Show(by popup menu) any AIS_InteractiveObject, not only AIS_Shape (e.g. AIS_Trihedron)
new Model->DFBrowser action to start Inspector tool with active DFBrowser plugin filled by the sample OCAF application.
To update content of the DFBrowser, use <F5> shortcut.
