Method IntWalk_PWalking::ExtendLineInCommonZone(...) now is not called if the already found intersection point is on surface boundary.
As result, the intersection line going along any boundary will never be extended. It is appropriate for high-level OCCT-algorithm because they will take the boundary (not computed line) as intersection result.
Do not limit the normalization factor of the highly anisotropic parametric space when filtering start points in the algorithm of walking line construction.
Additionally check the knots are in the increasing orders when merging two B-spline curves
ApproxInt_Approx, ApproxInt_KnotTools, BRepApprox_Approx,
GeomInt_IntSS, IntTools_FaceFace:
Analysis of curvature is added for adjusting ParametrizationType
IntPatch_Intersection.cxx - adding methods for estimation of UV max step depending on used surfaces
GeomInt_IntSS.cxx, IntTools_FaceFace.cxx - using methods for max step estimation
Approx_SameParameter.cxx - adding control against big values.
BOPAlgo_PaveFiller_6.cxx - adjusting position of faces before intersection
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.
Removed numerous unsafe reinterpret casts.
Generic classes Adaptor3d_GenHCurve, Adaptor3d_GenHSurface, Adaptor2d_GenHCurve2d have been removed.
Several redundant .lxx files have been merged into .hxx.

Correction of tests according to current results
lowalgos/intss/bug30703 - new test case added
"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.
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.
1. The condition of WLine breaking (in IntWalk_IWalking algorithm) has become more independent of the input tolerance.
2. Currently the algorithm of IntPatch_Points of WLine processing depends on the algorithm of obtaining the WLine.
3. The methods IntSurf_LineOn2S::Add(...) and IntSurf_LineOn2S::SetUV(...) have become not inline (see the message ~0077431 in the issue #29866).
In the fragment
if (aNewPnt[0] < u1min || aNewPnt[0] > u1max ||
aNewPnt[1] < v1min || aNewPnt[1] > v1max ||
aNewPnt[2] < u2min || aNewPnt[2] > u2max ||
aNewPnt[3] < v2min || aNewPnt[3] > v2max)
{
break; // Out of borders, handle this later.
}
the parameters are compared with values obtained by IntPolyh_MaillageAffinage algorithm and do not have any relations to the domain boundaries.
This misprint has been eliminated.
Since now a new WLine is not created if its start point lies in another earlier computed WLine. It allows avoiding creation of duplicate WLines in the intersection result.
<!break>
1. Methods IsOutSurf1Box(...), IsOutSurf2Box(...), IsOutBox(...) for classes IntSurf_LineOn2S and IntPatch_RLine have been created.
All library-specific macros for defining export / import properties of symbols on Windows (like Standard_API, __Draw_API, _math_API etc.) are eliminated.
Common macro Standard_EXPORT is used in all places where it is necessary.
New macro OCCT_STATIC_BUILD is defined for disabling Standard_EXPORT, to be used instead of HAVE_NO_DLL, though the latter is still supported as well (for compatibility).
To allow building OCCT in static mode on Windows after these changes:
- Files OSD_WNT_1.hxx and OSD_WNT_BREAK.hxx are removed; useful declarations are moved to OSD_WNT.hxx
- In the class IVtkVTK_ShapeData, static fields ARRNAME_MESH_TYPES and ARRNAME_SUBSHAPE_IDS are converted to static inline functions
- Global array ChoixRef defined in IntImp_ComputeTangence.cxx is converted to static function returning element of the array by index
- Unused class Quantity_Convert is removed (it had static field accessed by inline method)
- Struct Approx_Data defined in the same way in BRepApprox_Approx.hxx and GeomInt_WLApprox.hxx is made private member of these classes to avoid name clash
- Some C++ files producing no object code are removed
- In NCollection_EBTree.hxx and StdLPersistent_Collectio.hxx, definition of template virtual method is moved to class definition to avoid MSVC linker warnings on unused symbols
Some point were incorrectly removed from the Walking-line.
In the current fix, new method IntWalk_PWalking::RemoveAPoint(...) has been added and implemented in order to provide safe removing.
So, now methods AddAPoint(...) and RemoveAPoint(...) are recommended to use for work with the Walking-line.
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.
Generation of 3D-steps shorter than 3D tolerance has been allowed in the fix to build Walking-line.
Now, 3D-step is limited by Precision::Confusion value.
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.
Purger has been disabled (in IntPatch_PrmPrmIntersection algorithm) if some points have been added in the Walking line (it is stupidly, first, to insert some points in the line and, after that, to delete points from this line).
Some improvements in IntWalk_PWalking::SeekPointOnBoundary(...) method have been made (see comments in the code for detail information).
Some test cases have been adjusted according to their new behavior.
Now, the algorithm tries to estimate U- and V-ranges of future intersection curve(s) on the surface. This information is used in stop-criterium of the algorithm instead of full surface range used earlier. It allows reducing dependencies of intersection result on the surface ranges.
Tuning of test case bugs/modalg_6/bug27937_1
The algorithm that builds outlines ("silhouettes") makes an outline in 2d parametric space of the surface starting from some previously detected point where normal is orthogonal to direction of view. So, the surface is previously discretized into (m*n) sample points and some of them become starting points for future outlines.
If the surface has non-uniform parametrization and/or some local extremums of curvature, the outlines can not be built without breaks, so there are several groups of consequent outlines in this case. Unfortunately, it leads to the situation when current number of sample points becomes insufficient to build all the parts of outlines.
The idea is to detect the "holes" between already constructed parts of outlines and then complete the construction.
New auxiliary draw command for testing of HLR.
