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
1. The class Bnd_OBB has been created to describe the Oriented Bounding Box.
2. Several key methods have been implemented: Bnd_OBB::IsOut(...), Bnd_OBB::Add(...) and Bnd_OBB::Enlarge(...).
3. Interface of Bnd_Box class has changed. New methods have been created. See Bnd_Box.hxx for detailed information.
4. BRepBndLib and Draw_Box classes have been amended in order to provide correct work with Bnd_OBB class.
5. Interface of "bounding" DRAW-command has been changed. Please see help for detailed information.
6. New DRAW-command "isbbinterf" has been created. Please see help for detailed information.
7. "boundingstr" and "optbounding" DRAW-commands have been eliminated because their function can be made by "bounding" DRAW-command (e.g. see tests/bugs/vis/buc60857 or samples/tcl/snowflake.tcl test cases).
8. Documentation has been updated.
NCollection_UtfString and NCollection_UtfIterator classes are refactored to use methods overloading instead of switches to dispatch implementation depending on character (Unicode code unit) size.
ICC-specific preprocessor directives are added to avoid warnings.
Unused local functions and variables, class methods, unreachable statements, and extra throw() declarations reported by ICC are removed.
Usage of "expl" for name of local variable is avoided as it conflicts with standard C function "expl" defined in math.h as preprocessor macro.
Non-standard (MS-specific) argument envp is removed in definition of main() function on Windows.
Functions _main_ and _WinMain_ are renamed to Draw_Main and Draw_WinMain, respectively, to avoid using names reserved in C++.
Doxygen warning is fixed in XDE User's Guide.
OSD_OpenStream() now uses __gnu_cxx::stdio_filebuf extension for opening UNICODE files on MinGW when using C++ file streams.
Variant accepting filebuf returns bool (true if succeeded and false otherwise).
Checks of ofstream to be opened made via calls to low-level ofstream::rdbuf() are replaced by calls to ofstream::is_open(); state of the stream is also checked (to be good).
Unicode name used for test file in test bugs fclasses bug22125 is described (for possibility to check it).
Eliminated usage of TEXT macros, usage of OSVERSIONINFO instead of OSVERSIONINFOW.
LoadIcon/LoadCursor are now used instead of LoadIconW/LoadCursorW
when passing macros to standard resources (which depend on UNICODE flag).
Tests are added to control output and performance of progress indicator (bugs fclasses bug28478 and perf fclasses progress, respectively).
Implementation of class Draw_ProgressIndicator is improved to update indicator basing on achieved total progress (1% by default) instead of elapsed time since last update.
Method OSD_Chronometer::Restart() is fixed to actually reset the counter.
DRAW command readstl is improved to show progress indicator if configured (by command XProgress).
Description of class Message_ProgressIndicator is updated; code example is added in description of Message_ProgressSentry.
Image_VideoRecorder - added new class for video recording using FFmpeg framework.
Draw Harness command vanimation has been extended with new options for video recording.
New optional dependency has been introduced - CSF_FFmpeg.
Use of Cotire tool is introduced for acceleration of CMake builds, by usage of precompiled headers.
CMake option BUILD_USE_PCH is added to enable / disable use of precompiled headers
When precompiled headers are used, additional compiler macros are defined globally in the build system to avoid problems due to different order of included files:
- NOMINMAX is defined on Windows to prevent defining "min" and "max" as macros by windows.h
- STRSAFE_NO_DEPRECATE and _SCL_SECURE_NO_WARNINGS are defined on Windows to prevent declaring functions of standard C library as deprecated by #pragma, and other warnings in system headers
- GL_GLEXT_LEGACY and GLX_GLEXT_LEGACY are defined to ensure that only OCCT's own glext.h is used
- __STDC_FORMAT_MACROS is defined to have standard C print format macros always defined
Code is corrected to avoid conflicts with system headers and in case of compiling together as unity builds (partially):
- Some locally defined variables in TKV3d, TKHLR are renamed to be unique
- Duplicated definitions of macros and global functions are eliminated in TKSTEP
- Useless header WNT_UInt.hxx is removed
- Usage of local variables conflicting with X11 macro is avoided in Draw_Viewer.cxx
- Local variables in AIS_ConcentricRelation.cxx are renamed to avoid conflict with macros defined in windows.h
- HXX files containing code are renamed to PXX or merged with corresponding CXX files.
IVtkTools classes are corrected to avoid compiler warnings disabled in non-PCH builds by inclusion of VTK headers.
Useless pragmas disabling warnings on MSVC are removed
The method Draw_Interpretor::add() has been corrected so that the command getsourcefile returned the relative path starting with "src" without leading "/" on all platforms.
Enumeration Image_PixMap::ImgFormat, previously declared as nested
enumeration within class *Image_PixMap*,
has been moved to global namespace as Image_Format following OCCT coding rules.
The enumeration values have suffix Image_Format_ and preserve
previous name scheme for easy renaming of old values.
E.g. Image_PixMap::ImgGray become Image_Format_Gray.
Old definitions are preserved as depreacated aliases to the new ones.
Added new method Draw_Window::IsMapped() for checked window state.
Draw_Window using XLib now does not exit application on closing window.
The method Draw_Viewer::Select() (called by whatis command)
has been corrected so as not to enter the loop if no views are initialized.
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.
Eliminated usage of ANSI methods.
All Visual Studio projects generated by genproj or CMake use Unicode character set.
Draw Harness now handles Unicode input on Windows.
Tcl test scripts are now expected in UTF-8 encoding by default.
OpenGl_Workspace::BufferDump() now implicitly converts RGBA dump
into requested BGR, BGRA and RGB image.
DRAW command dversion is improved to report OpenGL variant used (desktop or ES); reporting of version of MSVC is corrected for VC14 and above; reporting of HAVE_OPENCL option is removed.
Usage of command vdump is corrected in some tests to specify extension .png for an image file.
Compiler warning is eliminated in OpenGl_Text.cxx (OpenGL ES mode only).
Added DRAW command dsetsignal, resetting OSD signal handler with either armed or disabled FPE handler, according to an option.
If called without arguments, it sets FPE handler only if environment variable OSD_FPE is defined (with value different from 0).
On start, DRAW calls dsetsignal to set FPE signal if CSF_FPE is defined.
Test bugs fclasses bug6143 uses dsetsignal to set FPE handler unconditionally before the test command, and resets it to default at the end.
A number of changes in the code have been done in order to fix floating point exceptions that became generated after enabling signals:
- Global functions Sinh() and Cosh() defined in Standard_Real.hxx are improved to raise Standard_NumericError exception if argument is too big (greater than 710.47586), instead of relying on system treatment of floating point overflow. These functions are used instead of sinh and cosh in ElCLib.cxx.
- Maximal value of parameter on hyperbola is restricted by 23 (corresponding to ~1e10 in 3d) in order to avoid FP overflow in Extrema_GenExtCS.cxx, ShapeFix_EdgeProjAux.cxx.
- Interface of the root curve adaptor class Adaptor3d_Curve has been updated to add new virtual methods BasisCurve and OffsetValue. They complement the adaptor for the case of offset curves. These methods are used in Extrema_GenExtCS.cxx to restrict domain search in the case of offset of hyperbola, in order to get rid of floating point overflow. All classes inheriting Adaptor3d_Curve have been changed to implement the new virtual methods.
- Protection against division by zero has been implemented in ApproxInt_KnotTools.cxx, BRepClass3d_SClassifier.cxx, BRepGProp_Face.cxx, BRepMesh_FastDiscretFace.cxx, Geom2dGcc_Circ2d2TanOnIter.cxx, Geom2dInt_Geom2dCurveTool.cxx, IntPolyh_MaillageAffinage.cxx.
- Protection against calling of math functions of infinite arguments has been added in BRepCheck_Edge.cxx, BRepLib.cxx, CSLib_NormalPolyDef.cxx, Extrema_FuncExtPC.gxx, Extrema_GExtPC.gxx, Extrema_GLocateExtPC.gxx, Intf_InterferencePolygonPolyhedron.gxx, ShapeAnalysis_Surface.cxx, ShapeAnalysis_TransferParametersProj.cxx, ShapeAnalysis_Wire.cxx, math_FunctionSetRoot.cxx.
- Proper initialization of local variables is done in BOPAlgo_PaveFiller_6.cxx, XSDRAWSTLVRML.cxx.
- Inconsistent usage of Standard_Boolean* to access integer data in HLR (caused by #27772) is corrected
Some test cases have been updated to actual state.
0027734: Configuration - TKIVtkDraw build fails with TBB: Remove unnecessary define statement (windows specific).
Small correction of test case for issue CR27567
TCollection_ExtendedString/TCollection_AsciiString description
has been updated to reflect usage of this classes for Unicode strings.

on Windows for consistency.
New macro Standard_UNUSED has been added for marking possibly unused functions and variables
(to suppress gcc/clang compiler warnings).
Code has been updated to remove no-op casts and implicit casts to Standard_Boolean.

for storing boolean flags
Method IFSelect_Dispatch::PacketsCount() has been dropped from interface.
ShapeFix_Solid::Status() has been fixed to decode requested status
instead of returning integer value.
