ShapeAnalysis::OuterWire(): fixed missed logic when TopoDS_Iterator notifies about more objects to iterate, but there are only vertices and no additional wires at all.
GeomConvert_CurveToAnaCurve, GeomConvert_SurfToAnaSurf - geometrical algorithms
for converting geometrical curve and surfaces in canonical geometry with given tolerance.
ShapeAnalysis_CanonicalRecognition - interface for checking canonical geometry.
Problem: the complete surface of the torus is not stored correctly in STEP format due to the fact that the edges are not properly ordered.
Change: added a mode for reordering edges in the wire with simultaneous use of 2d and 3d information (ShapeAnalysis_WireOrder). The new mode is used for torus-like surfaces before saving to STEP format.
Result: Torus correctly stored.
Possibility for adding LengthUnit info to XCAF document using special class XCAFDoc_LenghtUnit and XCAFDoc_LenghtUnitTool is implemented.
Package UnitsMethods is split: geom methods were placed to new file GeomConvert_Units which is in the toolkit TKXSBase, internal step scale factors was placed to StepData.
Updated UnitMethods to convert scale factor to different unit types.
Now, XSAlgo::XSAlgo_AlgoContainer is used to update unit info from static interface values.
New Draw command "XSetLengthUnit" and "XGetLengthUnit" for set or get XDE attribute.
Upgraded tests for STEP, IGES, OBJ, glTF, VRML formats to check area regressing with used unit.
Upgraded tests\de test cases to use any units in the "loop back" algorithms.
Add new class BRepLib_ValidateEdge to use for edge checking instead of functions:
- Validate() from BOPTools_AlgoTools.cxx
- Validate() from BRepCheck_Edge.cxx
- ShapeAnalysis_Edge::ComputeDeviation()
Adaptor2d_Curve2d, Adaptor3d_Curve and Adaptor3d_Surface now inherit Standard_Transient.
Interfaces Adaptor2d_HCurve2d, Adaptor3d_HCurve, Adaptor3d_HSurface and their subclasses
are now aliases to Adaptor2d_Curve2d, Adaptor3d_Curve and Adaptor3d_Surface.

Several redundant .lxx files have been merged into .hxx.
Removed obsolete adaptor classes with H suffix.
"endl" manipulator for Message_Messenger is renamed to "Message_EndLine".
The following entities from std namespace are now used
with std:: explicitly specified (from Standard_Stream.hxx):
std::istream,std::ostream,std::ofstream,std::ifstream,std::fstream,
std::filebuf,std::streambuf,std::streampos,std::ios,std::cout,std::cerr,
std::cin,std::endl,std::ends,std::flush,std::setw,std::setprecision,
std::hex,std::dec.
Evaluator of offset surface has been protected against evaluation at infinite parameters. Now it throws exception when evaluating such data.
The methods IsUClosed and IsVClosed of the class ShapeAnalysis_Surface have been corrected to avoid evaluation of the surface at infinite parameters (fighting with regressions "parasolid doc_3 E3" and "parasolid doc_2 A3" in products).
Added macro Standard_NODISCARD equivalent to C++17 attribute [[nodiscard]] for compilers that support this.
Using Standard_NODISCARD macro for methods that create new object in gp, math, Geom, Bnd packages.
Marked equivalent operators with Standard_NODISCARD, if they are defined close to relevant methods.
Corrected code where warnings on unused result of calls to methods creating new objects are generated.
In most cases it looks like spelling errors (e.g. Normalised() instead of Normalise())
TopoDS_Shape::NbChildren() - new method has been introduced.
TopoDS_Shape.lxx, TopoDS_TShape.lxx - inline methods have been moved to hxx.
TopoDS_TShape_Flags has been redeclared as enumeration instead of preprocessor macros.
Cyclic dependency between headers TopoDS_Shape.hxx and TopoDS_TShape.hxx eliminated.
Places where TopoDS_Iterator is used only for calculation of number of sub-shapes are updated to use NbChildren() instead
An extended draw-command trotate (ttranslate, tmirror, ...) by an additional parameter "-copy".
New check of edge range is added in BRepCheck/BRepCheck_Edge.cxx
The same checking is added in ShapeAnalysis_Edge.cxx
Fixing this problem is added in ShapeFix_Wire.cxx
GeomLib::SameRange(...) and BRepTools_TrsfModification::NewCurve2d(...) are modified to avoid exception in TrimmedCurve
Synchronization of the ShapeAnalysis_Edge behavior with the BRepCheck_Edge by adding check for 2d curves on planes.
Implementation of the BRep_Tool::CurveOnPlane method to avoid code duplication for making PCurve of the edge on planar face.
The iterating logic in ShapeAnalysis_Curve::GetSamplePoints() is made more robust: instead of iterative incrementing parameter by adding step, parameter at each point is calculated independently from index.
This avoids possible accumulation of numeric errors, and ensures that generated points are equally spaced and their quantity is respected in all cases.
1. Method Approx_ComputeLine::Perform is modified: now it contains also recursive calls after new line computation made by new method ApproxInt_MultiLine::MakeMLOneMorePoint.
2. New method MakeMLOneMorePoint is added to ApproxInt_MultiLine: it builds new sub-line as a part of main line with new point added into the middle of the longest interval between existing points.
3. Method ShapeConstruct_ProjectCurveOnSurface::ApproxPCurve is modified to avoid regressions: now it takes care of the set of initial points to be enough close to each other so that an interval between two adjacent points is less than half-period of the surface.
4. Modification in ShapeConstruct_ProjectCurveOnSurface: correction of pcurves of edges which extremities are in the singularities of surface.
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.
The cause of the bug was computation of incorrect UVBounds in the method ShapeAnalysis::GetFaceUVBounds. In this patch the computation of a box for a 2D curve in the method ShapeAnalysis_Curve::FillBndBox() has been improved taking into account intervals of C2 continuity.
Also the fix makes little extension of bounds when making the new surface in ShapeUpgrade_FaceDivide::SplitSurface(), so that all p-curves were fully inside.
Test case for issue CR28553
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.
Added DRAW command dsetsignal, resetting OSD signal handler with either armed or disabled FPE handler, according to an option.
If called without arguments, it sets FPE handler only if environment variable OSD_FPE is defined (with value different from 0).
On start, DRAW calls dsetsignal to set FPE signal if CSF_FPE is defined.
Test bugs fclasses bug6143 uses dsetsignal to set FPE handler unconditionally before the test command, and resets it to default at the end.
A number of changes in the code have been done in order to fix floating point exceptions that became generated after enabling signals:
- Global functions Sinh() and Cosh() defined in Standard_Real.hxx are improved to raise Standard_NumericError exception if argument is too big (greater than 710.47586), instead of relying on system treatment of floating point overflow. These functions are used instead of sinh and cosh in ElCLib.cxx.
- Maximal value of parameter on hyperbola is restricted by 23 (corresponding to ~1e10 in 3d) in order to avoid FP overflow in Extrema_GenExtCS.cxx, ShapeFix_EdgeProjAux.cxx.
- Interface of the root curve adaptor class Adaptor3d_Curve has been updated to add new virtual methods BasisCurve and OffsetValue. They complement the adaptor for the case of offset curves. These methods are used in Extrema_GenExtCS.cxx to restrict domain search in the case of offset of hyperbola, in order to get rid of floating point overflow. All classes inheriting Adaptor3d_Curve have been changed to implement the new virtual methods.
- Protection against division by zero has been implemented in ApproxInt_KnotTools.cxx, BRepClass3d_SClassifier.cxx, BRepGProp_Face.cxx, BRepMesh_FastDiscretFace.cxx, Geom2dGcc_Circ2d2TanOnIter.cxx, Geom2dInt_Geom2dCurveTool.cxx, IntPolyh_MaillageAffinage.cxx.
- Protection against calling of math functions of infinite arguments has been added in BRepCheck_Edge.cxx, BRepLib.cxx, CSLib_NormalPolyDef.cxx, Extrema_FuncExtPC.gxx, Extrema_GExtPC.gxx, Extrema_GLocateExtPC.gxx, Intf_InterferencePolygonPolyhedron.gxx, ShapeAnalysis_Surface.cxx, ShapeAnalysis_TransferParametersProj.cxx, ShapeAnalysis_Wire.cxx, math_FunctionSetRoot.cxx.
- Proper initialization of local variables is done in BOPAlgo_PaveFiller_6.cxx, XSDRAWSTLVRML.cxx.
- Inconsistent usage of Standard_Boolean* to access integer data in HLR (caused by #27772) is corrected
Some test cases have been updated to actual state.
The matter was that during checking wires of a shape for small area, non-outer wires were checked with constructing a new face with BRepBuilderAPI_MakeFace. If a face has location an edge from original face has no pcurve on the constructed face, which leads to exception in BRepGProp::SurfaceProperties. The fix constructs new face using EmptyCopy.
The method ShapeAnalysis_Wire::CheckSmallArea() has been changed so as to check area of the outer wire without hole-wires. API of this method has been changed, as the second argument theIsOuterWire is not needed any more.
The test cases have been updated, below are explanations of changes:
test de iges_2 G7
The fixed version leaves a wire in a face, but the master version considered it small and removed. The master version works wrong. It is because the face built with this wire has negative area, but the code in CheckSmallArea function does not get absolute value before comparing area with the tolerance. The left wire leads to splitting of the face on two, checkshape error in the face, and statshape faulty due to increased number of faces in the second pass.
test de iges_2 G2
The fixed version leaves a wire that is removed in the master version. The cause is the same as in G7 test case. However, here the problematic wire has very big tolerance. So, when the fixed version left it in the shape, the overall maximal tolerance became much greater than in reference data.
test de step_3 E6
In fixed version a really bad small wire is removed from the face, while in master version it is left and produces an error in checkshape report. So, it is an improvement.
Code has been updated to remove no-op casts and implicit casts to Standard_Boolean.
Places of inproper use of Standard_Boolean instead of Standard_Integer
have been corrected:
- Bnd_Box, Bnd_Box2d
Bit flags are now defined as private enum
- HLRAlgo_BiPoint, HLRAlgo_EdgesBlock, HLRBRep_EdgeData, HLRBRep_FaceData
Bit flags are now defined as enum
- HLRAlgo_EdgeStatus, HLRBRep_BiPnt2D, HLRBRep_BiPoint
Bit flags are now defined as bool fields
- HLRAlgo_PolyData
Bit flags are now defined as Standard_Integer
- OSD_DirectoryIterator, OSD_FileIterator
Boolean flag is now defined as Standard_Boolean
- ShapeAnalysis_Surface::SurfaceNewton()
now returns Standard_Integer (values 0, 1 or 3)
- ChFi2d_FilletAlgo
now uses TColStd_SequenceOfBoolean instead of TColStd_SequenceOfInteger
for storing boolean flags
Method IFSelect_Dispatch::PacketsCount() has been dropped from interface.
ShapeFix_Solid::Status() has been fixed to decode requested status
instead of returning integer value.
TopOpeBRepBuild_Builder1 now defines map storing Standard_Boolean values
instead of Standard_Integer.
Persistence for Standard_Boolean type has been corrected
to keep backward compatibility:
- BinMDataStd, BinTools, FSD_BinaryFile
Broken Draw Harness commands vdisplaymode and verasemode have been removed.
BRepMesh_FastDiscretFace::initDataStructure() - workaround old gcc limitations
BRepMesh_IncrementalMesh::clear() - avoid ambiguity
ShapeAnalysis_Surface is improved to use adaptor for evaluation of points on a surface.
Useless field myExtSur is removed.
DE tests are amended according to induced changes (number of edges varied).
C2 continuity intervals changed to Knots intervals in case of Bspline curve.
Fixed incorrect extremaPC usage.
Test case for issue CR26351
Update of test-cases according to the new behavior
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.
Missing headers added; includes of headers "Handle_...hxx" removed.
Misuses of macro Handle() and its use in typedefs corrected.
Alias classes Profile and Option are removed from IFSelect; ones defined in MoniTool are used directly.
Removed header files defining only Handle classes (except Image_PixMap_Handle.hxx)
Classes SelectMgr_BaseFrustum and now inherit Standard_Transient and can be manipulated by Handle (not NCollection_Handle)
Fixed reference-type local variable pointing to temporary object
Use of handle in conditional expressions and comparisons to NULL are replaced by call to method IsNull()
A tool to remove tails from the wires of a shape was created.
The tool is based on mechanism 'ShapeFix',
is located in types 'ShapeFix_Wire' and 'ShapeAnalysis_Wire',
is enabled through method 'ShapeFix_Wire::FixTailMode' and
is initialized by methods 'ShapeFix_Wire::SetMaxTailAngle' and 'ShapeFix_Wire::SetMaxTailWidth' and
is called through method 'ShapeFix_Wire::FixTails'.
The status of any performing of the last method is accessible through method 'ShapeFix_Wire::StatusFixTails'.
The tail angle is checked only at the tail start.
Mechanism 'ShapeFix' was modified:
- the tool is disabled by default;
- algorithm 'Fix notched edges' is disabled then the tool is enabled;
- the tool and the last algorithm work in turns then the tool works on the request.
'Draw' command 'fixshape' was extended by options '-maxtaila' and '-maxtailw' to test the tool.
'Draw' tests to test the tool were created.
Algorithm 'fixshape' was changed in type 'ShapeProcess_OperLibrary' to
- use new parameters named 'FixTailMode', 'MaxTailAngle' (in degrees) and 'MaxTailWidth' from the algorithm context;
- apply the tool after the shape will be fully fixed if the tool was enabled.
Place holders for the new parameters were created in the resource file of mechsnism 'STEPControl_Reader'.
Test cases for issue CR26261
1. B-spline cache was moved into separated classes: BSplCLib_Cache for 2D and 3D curves and BSplSLib_Cache for surfaces.
2. The cache is used now in corresponding adaptor classes (Geom2dAdaptor_Curve, GeomAdaptor_Curve and GeomAdaptor_Surface) when the curve or surface is a B-spline.
3. Algorithms were changed to use adaptors for B-spline calculations instead of curves or surfaces.
4. Precised calculation of derivatives of surface of revolution is implemented for the points of surface placed on the axis of revolution (Geom_SurfaceOfRevolution.cxx)
5. Small modifications are made to adjust algorithms to new behavior of B-spline calculation.
6. Test cases were modified according to the modern behavior.
7. Changes in BOPAlgo_WireSplitter, BOPTools_AlgoTools, BRepLib_CheckCurveOnSurface and ShapeAnalysis_Wire to use adaptors instead of geometric entities
8. Allow Geom2dAdaptor and GeomAdaptor in case of offset curve to use corresponding adaptor for basis curve
Modification of test-cases according to the new behavior.
