"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.
1. Extrema algorithm calls Curve-surface intersector. This intersector returns flag about infinite solution (in spite of extrema's returning not-parallel status correctly - axes of considered cylinder and circle are not parallel). In this case, attempt of obtaining number of intersection points leads to exception.
So, the fix adds check of infinite solution after the intersection algorithm.
2. The methods IsDone(), IsParallel(), NbExt(), SquareDistance() and Points() (of Extrema_* classes) have been corrected to make them consistent to the documentation.
3. Revision of some Extrema_* classes has been made in order to avoid places with uninitialized variables.
4. Currently Extrema does not store any points in case when the arguments are parallel. It stores the distance only.
5. Some cases on Extrema-algo have been moved from "fclasses"-group to "modalg"-group.
Simple treatment of some analytical cases when curve is parallel or belongs surface is added in curve - face/surface intersection algorithm
Treatment such cases is added in classifier algorithm
Test case added
Eliminated GCC warning -Wsign-compare introduced by patch for #0028786.
Eliminated (false) GCC warning -Wuninitialized introduced by patch for #0027117.
Suppressed GCC warning "-Wunused-but-set-variable" with OCCT_DEBUG defined
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.
Various improvements in point-solid classifier:
1) Refactoring.
2) BndBoxTree is extracted into separate class.
3) UB-tree calculation is cashed to improve point-solid classification speed.
4) Ray / curve intersection improved by trimmed parameters and correct order.
5) Fixes in logic.
6) Calculation caching at the classifier level.
3D-claasifier now takes into the account the vertex/edges tolerances. If the given point lays inside the tolerance area of vertex or edge of the solid it's classified as TopAbs_ON.
The behavior of IntCurvesFace_Intersector::Perform was changed. Now it may use optional null-tolerance to classify 2d-point relatively to the given face.
UBTreeFiller is used to speedup intersection process between edges/vertices and the point.
The test case 'boolean gdml_private ZH2' extensively uses the SolidClassifier. After this fix it returns the correct classification statuses, which leads to incorrect result shape (reported by checkshape). Yet the result shape without this fix also seems to be incorrect (one of the isolines goes out of boundary of the face). Thats why it's marked with 'TODO'.
Corrections in test cases.
Test case is added.
Check for orientation of the solid corrected to ensure that cycle always finishes.
Test case added: bugs modalg_6 bug26627
Tests boolean volumemaker A3, B5, B7 corrected (improvements)
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
Implemented additional verification that the point found by Extrema is placed inside the face. This way turns off searching the additional inner point.
