0032969: Coding - get rid of unused headers [IMeshData to PLib] Removed unused exception classes OSD_Exception_FLT_DIVIDE_BY_ZERO, OSD_Exception_INT_DIVIDE_BY_ZERO, OSD_Exception_FLT_DENORMAL_OPERAND, OSD_Exception_FLT_INEXACT_RESULT, OSD_Exception_FLT_INVALID_OPERATION, OSD_Exception_FLT_OVERFLOW, OSD_Exception_FLT_STACK_CHECK, OSD_Exception_FLT_UNDERFLOW.
0032701: Modeling Algorithms - 2d curve has bending near the degenerated edge of the face 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
0028966: Coding Rules - remove Adaptor2d_HCurve2d, Adaptor3d_HCurve and Adaptor3d_HSurface classes 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. Removed obsolete adaptor classes with H suffix.
0030895: Coding Rules - specify std namespace explicitly for std::cout and streams "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.
0029972: Intersection curve has a weird gap in the middle of it 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).
0028626: Boolean CUT operation fails due to exception while intersecting two conical faces 1. Modification in static function IntersectionWithAnArc of IntPatch_ImpImpIntersection : small offset <du> was hardcoded as 1.e-9, now it is adapted to parametric step. 2. Removal of duplicated points of IntPatch_WLine is corrected.
0026937: Eliminate NO_CXX_EXCEPTION macro support 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.
0027896: Prm-Prm intersection algo returns wrong result if it is called with start intersection point, which lies in the domain boundary 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.
0026980: Intersection algorithm spends much system time and system memory 1. Step of Walking-line has been increased as possible and now computes by iteratively adaptive algorithm (every iteration checks if current step is too big/small and decreases/increases one). 2. Interface of IntWalk_PWalking class has been changed 2.1. Method MaxStep() has been added in order to know about maximal distance between 2D-points. 2.2. Method ComputePasInit(...) has been added in order to initial step value computation. 2.3. Fields myTolTang (tolerance for intersection algorithm) and myStepMin (minimal step value) have been added. Correction of some test cases. Creation test case for this issue. Changes to eliminate compiler warnings.
0026621: Boolean Cut does not work on two solids The main reason of the bug is incorrect extending line in SeveralWlinesProcessing(...) function. Additionally, interface of IntPatch_WLine::Dump(...) method has been changed. Change some test cases according to their new behavior. Test-case for issue #26621
0024002: Overall code and build procedure refactoring -- automatic 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
0024023: Revamp the OCCT Handle -- downcast (automatic) 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.
