The main reason of the bug is incorrect check, if the edge is seam-edge or not.
In the fix it is determined with new methods in GeomLib class.
The bug is fixed.
Creation of test case for this fix
Small correction in the code
PRO file is added + a description of how to generate the Visual Studio projects and compile.
In addition, the sample folder is renamed to FuncDemo.
Adding 64 bit configuration to VC projects
- updated description of selection mechanism in sections occt_visu_2_2, occt_visu_3_2_4 and occt_visu_3_6;
- unnecessary images were removed.
New Selection section reviewed.
Semantic corrections
Method DownCast() is made template, to be available only when argument is actually a pointer or handle to a base class.
For compatibility with existing code, method DownCast() that can be used for the same type, derived, or unrelated class (i.e. where there is no actual down casting) is still available, its use shall cause "deprecated" compiler warning.
OCCT code is updated to remove meaningless DownCast()s; a few places where DownCast() was used with argument of unrelated type are corrected.
DRAW command QAHandleCast is removed (it was useful only during redesign of handles).
Copy constructor and assignment operator from handle of derived type is added in handle class.
They are enabled only if macro OCC_HANDLE_NOCASTS is defined, and operators of cast of handle to reference to handle to base type are disabled in that case.
Useless type casts to handle to base type are removed in GC and GCE2d classes.
Code returning reference to handle from function is corrected to return it either by value or as reference to handle of actual type.
Operator of cast to non-const reference is declared deprecated to produce compiler warning if used (usually implicitly).
OCCT code is updated to avoid that cast, occurring when function accepting non-const reference to handle is called with handle to derived type.
For that, local variable of argument type is passed instead, and down-cast is used to get it to desired type after the call.
A few occurrences of use of uninitialized variable are corrected.
Patch removes option -wd4996 from VS project settings (which suppresses old deprecation warnings).
Instead, macros _CRT_SECURE_NO_WARNINGS (suppresses 444 warnings) and _CRT_NONSTDC_NO_DEPRECATE (suppresses 17 warnings) have been added.
Deprecation warning on GetVersionEx() has been suppressed locally in OSD_Host.cxx.
In STEPConstruct_AP203Context.cxx, OSD_Host is used instead of low-level system functions.
This eliminates dependency of TKSTEP on winsock32.lib on Windows.
Macro Standard_DEPRECATED("message") can be used in declarations to mark a method deprecated and generate compiler warning when it is used.
If OCCT_NO_DEPRECATED is defined, Standard_DEPRECATED is disabled (defined empty).
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).
Lipchitz constant approximation and fixes in global optimization algorithm added to improve performance.
Test case added.
Possibility to freeze Lipchitz constant is added to improve performance.
Generation of debug info is explicitly disabled on link step in templates of Visual Studio 10+ project files used by genproj, to avoid relying on default settings of Visual Studio.
Use std::mt19937 random number generator instead of rand() in NCollection_UBTreeFiller.
boolean gdml_private ZI7 ZJ7 - TODO "bopcheck failed" is only for Linux now, checkshape faulty is unstable (issue #27052)
boolean volumemaker B6 - Added TODO (bopcheck and checkshape faulties)
boolean volumemaker C9 - Added TODO (checkprops and checkshape faulties)
boolean volumemaker D2 - Added TODO (checkshape faulty)
boolean volumemaker H4 - Added TODO (checkprops and checkshape faulties Linux only)
boolean volumemaker D5 - IMVPROVEMENT, TODOs were deleted (bopcheck and checkshape faulties)
bugs modalg_1 buc60462_2 - modified TODOs according to new behavior
boolean gdml_private ZI7 ZJ7 - unstable case, added check for surface area and TODO
samples/tcl/ANC101.tcl - amended due to changed order of edges in BOP result
CMake script is corrected to add compiler options (except macro definitions) to CMAKE_CXX_FLAGS and CMAKE_C_FLAGS variables directly, instead of using add_definitions() command.
This eliminates failure of build by NMake due to incorrect options passed to RC compiler.
Two new sample scripts added, modeling classic shapes from used for comparing modeling systems in 1979 and again in 1983 by Computer Aided Manufacturing International (CAM-I).
BRepMesh_CircleTool: extend radius of circle by quite small value in order to classify points forming inscribed triangle as lying on it. Do not use PConfusion due to false positive result leading algorithm to hanging.
Small correction in test cases bugs/mesh/bug27119
Update of test cases according to the new behavior:
bugs/moddata_1/bug22759
mesh/data/standard/M4
Virtual method Generated() inherited from BRepPrimAPI_MakeSweep is overridden in class BRepOffsetAPI_MakePipe, providing information on shapes generated from the profile.
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.
Extrema Curve / Surface algorithm changed to perform more accurate search.
test case bug25232_8 - improvement, one additional intersection point is detected now.
test case bug23830 - normal behavior, position of extrema is changed.
test case for original issue added.
Method BRepGProp::LinearProperties() is corrected to treat not geometric edges (their length is zero). To avoid wrong working of command nexplode global properties are calculated as point properties of vertexes. Small value Epsilon(1.) is used as density of points. This prevents exception on shapes that contain such edges, e.g. copy of a wire containing degenerated edge.
Method BRep_Tool::IsGeometric() is optimized to avoid nested iteration for check of 3D curve for Null.
Small bug is fixed in GProp_PGProps.cxx
Useless variable MAXTOLERANCEGEOM is removed in order to allow to place point at any distance from curve/surface.
Algorithm is simplified: particular calculations for analytical geometry are removed, only using of Extrema_... is kept.
Test case for issue #27110
checkdump - procedure to parse output dump and compare it with reference values;
checklength - procedure to compute length of input shape.
Added procedures and modified test group geometry.
1. Disable recalculation of B-spline cache when the parameter is out of surface boundary but near the cached span.
2. Rebuild cache each time a curve/surface is loaded into adaptor (B-spline knots may be re-parametrized outside adaptor without changing base curve)
3. Test cases.
