Toolkit 'TKHLR' was fully refactored for 'Standard_Address' and macros except about half of package 'HLRBREP' there 'Standard_Address' is used through the 'generic' mechanism.
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.
Correction according to the remarks.
Update of test case according to the developer's directive
The following modifications were done for stability:
- Precision::PConfusion() was set as parameter of Classifier instead of 0.0
- Coinciding vertices of outlines are united to exclude neighborhood of common vertex from curve-curve intersection
- Draw command "hlrin3d" was modified to prevent exception
Minor corrections
Corrections of test cases for issue CR27557
- removal of excess interferences in case of simple hiding face
- correct processing of boundary edges coinciding with outlines
- change of API for testing Draw Command
- correction of Draw command "build3d"
- test cases are added.
Linux reference data is changed.
Partially fixed 0027340: Insufficient exact HLR speed
Number of samples in PolyPoly intersection algorithm tuned in each instance of generic class.
Default number of the samples in Geom2dAdaptor is changed according to the Adaptor2d_Curve2d class.
Minimal number of points in case of B-Spline is changed.
Minimal number of samples support is added in intersection algorithms.
1) Macro definition WNT replaced by _WIN32 and _MSC_VER for platform and compiler detection accordingly.
2) Macro definition LIN replaced by __linux__ macro.
3) Macro definition DEB replaced by OCCT_DEBUG macro.
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
Mostly duplicated comments were removed and missing ones were moved
into dedicated class CDL files.
Some more duplicated comments were removed from CDL files.
Correction of merge
Redundant keyword 'mutable' removed in CDL files.
In IGESConvGeom_GeomBuilder, unused methods MakeXY() and MakeXYZ() removed.
Method StepAP214_AutoDesignGroupAssignment::Init() replicating same method of the base class is removed as it causes CDL extraction error after above (seemingly irrelevant) changes.
License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.
When warnings are enabled, compilers report lots of occurrences
of unused local variables, which makes it harder to find other
meaningful warnings.
This commit does not fix all unused local variables.
Fix new type conversion warning
Code cleaned to avoid MSVC compiler warnings on unused function arguments.
Several useless pieces of code are removed.
Changes in IntTools_EdgeFace.cxx, Blend_Walking_1.gxx, Bnd_BoundSortBox.cxx, ProjLib_ProjectedCurve.cxx are reverted (separated to specific issue for more in-depth analysis).
Added DRAW command dlocale to set and query current locale of the C subsystem
Equivalents of C functions working with conversions of strings to/from reals added in Standard_CString, providing locale-independent behavior (using always "C" locale)
In DRAW packages, calls to atof() and atoi() are replaced by direct calls to Draw::Atof() and Draw::Atoi(), respectively, instead of substituting by #define
Use of atof(), strtod(), and *scanf() involving floating point conversions in OCCT code replaced by locale-independent Atof() and Strtod()
Calls to sprintf() involving floating point in OCCT code are replaced by call to locale-independent Sprintf(), except a few places where converted strings are used immediately for display in the 3d viewer
Changes of global locale are eliminated throughout OCCT code
Proposed correction for GNU libC where v*printf_l functions are absent
Added test case (bugs xde bug22898) for data exchange operations with non-standard locale
Use xlocale on Mac OS X and within glibc
Corrected strtod_l wrapper
Generate error rather than warning
Introduce Standard_CLocaleSentry replacement for removed OSD_Localizer
Standard_CLocaleSentry - copy locale string
Standard_CLocaleSentry - use _configthreadlocale on Windows
Standard_CLocaleSentry::GetCLocale() - return locale_t rather than void*
Corrected misprint in ~Standard_CLocaleSentry()
Use French locale in bug22898 test case
Mark test case as skipped if locale is unavailable on tested system.
Use fr_FR locale for tests on Mac OS X
