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.
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.
Creation the test case for current issue.
Added flag for single extrema computation. Now implemented only for parametric solver GenExtCC.
Default behavior of curve/curve solver in distmini command changed to "find one solution".
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
math_GlobOptMin - new global optimization minimization algorithm
Extrema_GlobOptFuncCC, Extrema_ExtCC, Extrema_ExtCC2d - implementation of GlobOptMin algorithm to extrema curve / curve
Extrema_CurveCache - deleted as obsolete code
ChFi3d_Builder.cxx - fixed processing of extrema
math_NewtonMinimum.cxx - fixed step to avoid incorrect behavior
Test cases modification to meet new behavior.
1) Generic class "GccEnt_QualifiedCurv" from "GccEnt" package converted to the non-generic class and moved to the "Geom2dGcc" package. Name of this class was changed to "Geom2dGcc_QCurve".
2) Generic classes "HatchGen_ElementGen", "HatchGen_ElementsGen", "HatchGen_HatchingGen" and "HatchGen_Hatcher" from "HatchGen" package converted to the non-generic classes and moved to the "Geom2dHatch" package. Names of this classes were changed to "Geom2dHatch_Element", "Geom2dHatch_Elements", "Geom2dHatch_Hatching" and "Geom2dHatch_Hatcher". Also all instantiations of the "internal" classes of this classes were moved to the "Geom2dHatch.cdl".
3) Generic classes "Extrema_GExtCC", "Extrema_GExtCC2d", "Extrema_GLocateExtCC" and "Extrema_GLocateExtCC2d" from "Extrema" package converted to the non-generic classes. Names of this classes were changed to "Extrema_ExtCC", "Extrema_ExtCC2d", "Extrema_LocateExtCC" and "Extrema_LocateExtCC2d". Also all instantiations of the "internal" classes of this classes were moved to the "Extrema.cdl".
