Methods IsParallel() and SetParallel() have been added to BVH_Sorter, BVH_DistanceField and BVH_BuilderTransient to control parallel execution on low-level.
Fix compilation errors for old compilers without support of c++11 (std::begin, std::end)
Explicit calls to TBB in BVH_DistanceField, BVH_LinearBuilder and BVH_RadixSorter have been replaced.
Task functors have been separated on execution and state parts for the sake of usage by OSD_Parallel.
The following changes have been made for improving the offset algorithm:
1. Multi-connexity support - intersection of the faces connected to the edge belonging to more than two faces is now performed.
2. Avoid intersection of the faces connected through internal edge.
3. Filling gaps (holes) in the splits of the created offset faces to increase possibility of creation of the closed volume from these splits.
Test cases for the issue.
Implementation of the new class *BOPAlgo_MakeConnected* for making the group of touching same-dimensional shapes connected.
Provide the material association for the first sub-elements of the input shapes.
Provide possibility to make the connected shape periodic.
Draw commands for new algorithm:
* makeconnected - make the input shapes connected or glued, performs material associations;
* cmaterialson - returns the materials located on the requested side of a shape;
* cmakeperiodic - makes the connected shape periodic in requested directions;
* crepeatshape - repeats the periodic connected shape in requested directions requested number of times;
* cperiodictwins - returns all periodic twins for the shape;
* cclearrepetitions - clears all previous repetitions of the periodic shape, keeping the shape periodic.
Documentation & test cases for the new algorithm.
Implementation of the new class *BOPAlgo_MakePeriodic* for making the shape periodic in 3D space.
Periodicity of the shape means that the shape can be repeated in any periodic direction any number of times without creation of the new geometry or splits.
The idea of this algorithm is to make the shape look similarly on the opposite sides or on the period bounds of periodic directions.
It does not mean that the opposite sides of the shape will be mirrored. It just means the the opposite sides of the shape should be split by each other and obtain the same geometry on opposite sides.
Such approach will allow repeating the shape, i.e. translating the copy of a shape on the period, without creation of new geometry because there will be no coinciding parts of different dimension.
Draw commands for the new algorithm:
* makeperiodic - makes the shape periodic in required directions;
* repeatshape - repeats the periodic shape in requested periodic direction;
* periodictwins - returns the periodic twins for the shape;
* clearrepetitions - clears all previous repetitions of the periodic shape.
Documentation & test cases for the algorithm.
1. Test case for the issue has been created. The issue is fixed by the patch #26106.
2. Since now, "tricheck" command uses edge tolerance instead of edge deflection to check cross-face-errors (set of nodes of the edge on 1st face must be equal to set of nodes of the same edge on 2nd face).
Now end points of intervals calculated in GeomAdapter_Curve are not replaced by GeomAdapter_Surface.
Left bound of periodic curve less than UMin is not corrupted by LocateParameter during intervals calculating.
Implementation of capturing of output to standard streams in DRAW (see command dlog) is revised to avoid problems with command "test" executing long test scripts:
1. Method OSD_File::Capture() is removed: on Windows it was allocating a C file descriptor for a file opened using WinAPI, and never released that descriptor (once allocated, it cannot be released separately from WinAPI file handle). Direct calls to dup/dup2 are used instead.
2. In Draw_Window.cxx the standard Tcl channels are initialized manually using corrected version of Tcl internal function. This works around a problem with Tcl channels on Windows being bound to OS device handle owned by the system which can get invalidated as result of calls to dup2() (used to capture output to standard streams).
3. Temporary file for capturing is opened once and used to store whole log, thus the need to collect log in the string stream in memory is avoided
4. Possible errors of dup() and dup2() are checked and reported
Test demo draw dlog is added
Off-topic changes:
- Test demo draw getsource is corrected for VS2017 which generates file name in lowercase
- Field myFaceBounds is initialized in constructor of the class BRepAlgo_NormalProjection to avoid undefined behavior
- Test bugs modalg_5 bug24012 is corrected to use command nproject instead of custom one, and to check propertes of the resulting shape
Two new functionalities have been added in BRepFilletAPI_MakeChamfer:
- constant throat (the section of chamfer is isosceles triangle, its height is constant in all sections - this is the "throat" of the weld);
- constant throat with penetration(the section of chamfer is right-angled triangle, the first of two surfaces (where is the top of the chamfer) is virtually moved inside the solid by offset operation, the apex of the section is on the intersection curve between moved surface and second surface, right angle is at the top of the chamfer, the length of the leg from apex to top is constant - this is the "throat" of the weld).
- New abstract classes BlendFunc_GenChamfer and BlendFunc_GenChamfInv have been added;
- Class BlendFunc_Chamfer is now descended from BlendFunc_GenChamfer, class BlendFunc_ChamfInv is now descended from BlendFunc_GenChamfInv.
- New class BlendFunc_ConstThroat is descended from BlendFunc_GenChamfer, new class BlendFund_ConstThroatInv is descended from BlendFunc_GenChamfInv.
- New class BlendFunc_ConstThroatWithPenetration is descended from BlendFunc_GenChamfer, new class BlendFund_ConstThroatWithPenetrationInv is descended from BlendFunc_GenChamfInv.
- Class ChFi3d_ChBuilder has now mode of chamfer that can be ClassicChamfer, ConstThroatChamfer and ConstThroatWithPenetrationChamfer.
- Two new DRAW Test Harness commands "chamf_throat" ant "chamf_throat_with_penetration" have been added for the second mode of ChBuilder.
- The interface of DRAW Test Harness command "chamf" changed for symmetric case.
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.
Split seam edge of a cone according to the specified parameters.
Seam edge functor is called before check of triangulation consistency in order to keep face status consistent.
The cause is that split seam edge can set Outdated flag when Reused is set by another functor without reset which can lead to refusement of such face by triangulation procedure.
