Make C++ standard to be enable from cmake settings:
User will be able choosing C++ language standard by selecting cmake variable BUILD_CPP_STANDARD.
For correct working, CMAKE_CXX_STANDARD cmake built-in variable should be available.
To enable CMAKE_CXX_STANDARD, minimum CMAKE version has been updated to 3.1.
Available next standard items:
C++11
C++14
C++17
C++20
C++23
This issue consists from several steps to achive main goal:
1) Configuratiuon, CMake - allow selecting C++ standard.
2) Require minimum CMAKE version 3.1 (for enabling CMAKE_CXX_STANDARD).
3) More flexible CMAKE_CXX_COMPILER_ID identification (fixups previous commit!)
4) Add description of new CMAKE variable `BUILD_CPP_STANDARD` into documentation.
5) Update CMAKE requirements in documentation.
6) Set C++11 standard for several projects.
While demanding c++ language standard c++20, the error of OCCTProxy compilation is occured:
warning C4857: C++/CLI mode does not support C++ versions newer than C++17; setting language to /std:c++17
error C7681: two-phase name lookup is not supported for C++/CLI or C++/CX; use /Zc:twoPhase-
Officially, C++/CLI mode does not support C++ version newer than C++17, so we should not demand C++20 to compile csharp samples.
Alternative solution - using /permissive (ConformanceMode = false), rather than default value /permissive- (ConformanceMode = true)
option to compile OCCTProxy. But alternative solution has been denied.
So, here is nothing to do to fix compilation of OCCTProxy project.
Nevertheless, error occures in IE_WPF_WinForms and IE_WinForms - if we trying to compile with VC++ 2022 (not demanding c++20):
warning MSB3274: The primary reference "*\OCCTProxy.dll" could not be resolved because it was built against the ".NETFramework,Version=v4.7.2" framework.
This is a higher version than the currently targeted framework ".NETFramework,Version=v4.0".
To solve the problem it is proposed to demand by default the highest version of NETFramework - 4.8.
So, demanding NETFramework v4.8 does not crashing compilation of csharp samples with VC++ 2015.
Image_PixMap has been extended to support definition of 3D bitmap (as an array of 2D slices).
Graphic3d_TypeOfTexture enumeration values have been renamed to include full enum prefix.
Added Graphic3d_TypeOfTexture_3D redirecting to GL_TEXTURE_3D.

Added Graphic3d_Texture3D class.
vtexture - added argument -3d for uploading 3D texture.
Fixed emscripten_async_call() calls to use requestAnimationFrame() instead of setTimeout().
ViewerTest_EventManager::handleViewRedraw() - fixed queuing new onWasmRedrawView()
before previous one has been processed (leading to multiplying of pending redraws executed at the same time).
RWGltf_TriangulationReader::readDracoBuffer - suppressed CLang compilation warnings.
Prs3d_Drawer getters now return NULL instead of implicitly creating "default" aspects.
Added missing initialization of default properties in AIS_InteractiveContext.

ViewerTest_EventManager - added tracking of EMSCRIPTEN_EVENT_FOCUSOUT event.
onWasmMouseCallback() has been adjusted to return FALSE for EMSCRIPTEN_EVENT_TARGET_WINDOW
target to avoid misbehavior of other HTML controls.
WNT_Window::ProcessMessage() now handles WM_SETFOCUS/WM_KILLFOCUS instead of WM_ACTIVATE to track focus changes.
AIS_ViewController::ProcessFocus() now redirects to AIS_ViewController::ResetViewInput() on focus loss.
This fixes issues when key action (like WASD navigation) keep working even after releasing key if window has been switched.
Wasm_Window::ProcessMouseEvent() - removed redundant check on EMSCRIPTEN_EVENT_MOUSEUP event.
ViewerTest and WebGL sample - mouse movements are now tracked on window element
to allow tracking updates when mouse with clicked button is moved outside canvas element.
The following classes have been removed as obsolete:
- BRepAlgo_BooleanOperation
- BRepAlgo_Fuse
- BRepAlgo_Cut
- BRepAlgo_Common
- BRepAlgo_Section
The corresponding classes from BRepAlgoAPI package have to be used instead.
Draw commands:
- fuse
- cut
- common
- section/psection
have also been removed as obsolete.
The corresponding commands for modern Boolean operations algorithm (bfuse/bcut/bcommon/bsection) have to be used instead.
Adjustment of the test cases to use the commands for modern algorithm.
vlight command has been revised to provide more friendly syntax.
Command now accepts light index or name as first argument.
Added arguments -enable/-disable for managing enabled state.
Added argument -reset to reset light parameters to default values.
V3d_Viewer::SetDefaultLights() now sets names "headlight" and "ambient" to created lights.
Graphic3d_TypeOfLightSource enumeration values have been renamed to avoid shortcuts.
Draw::Atof(), applied corrections to avoid explicit new/delete calls.
Code has been adjusted to suppress -Wunused-but-set-variable warnings.
DRAWEXE.wasm, compiler flags have been moved to linker flags
to eliminiate -Wunused-command-line-argument warnings.
Introduced Wasm_Window implementing Aspect_Window interface.
Aspect_WindowInputListener has been extended by touch input callbacks (moved from AIS_ViewController),
which now implements redirection of single taps to UpdateMouseClick().
AIS_ViewController::FetchNavigationKeys() now requests more frames even if Delta is zero,
but navigation keys are pressed - indicated by a new flag AIS_WalkDelta::IsDefined().
Fixed missing implementation of Xw_Window::DisplayConnection() getter.
The property has been moved to the base class Aspect_Window.
Removed unused Aspect_Convert.hxx.
DRAWEXE targeting Wasm:
- added exposing of FS interface so that it is possible uploading/downloading files to/from emulated file system on JavaScript level;
- added printer redirecting messages to Module.printMessage callback accepting message gravity;
- Run_Appli() now skips std::cin when Module.noExitRuntime is set.
DPLUGIN() macros no more defines exported function PLUGINFACTORY when building static libraries.
DRAWEXE executable now pre-loads a set of plugins when building static libraries.
dversion - added WebAssembly info.
Added TKOpenGlTest and TKD3DHostTest Draw Harness plugins.
TKOpenGlTest is automatically loaded by ViewerTest::ViewerInit().
Commands vgldebug, vvbo, vcaps and vuserdraw have been moved to TKOpenGlTest.
New command vglshaders lists GLSL programs defined by OpenGl_GraphicDriver,
previously implemented by "vshaderprog -list".
Added new command vdriver for graphic driver selection.
Removed erroneous code from command vstereo.
- moved creating of V3d_View::myTrihedron from constructor to first attempt of displaying or calling it;
- moved creating of V3d_Viewer::myRGrid and V3d_Viewer::myCGrid to to first attempt of displaying or calling them;
- renamed V3d_Viewer::IsActive() to V3d_Viewer::IsGridActive();
- redefined V3d_View::Trihedron() and V3d_Viewer::Grid() by adding new argument toCreate
for opportunity to check the existence of the objects without their recreating.
Fixed multitouch input.
Module is now exported with global functions hidden via MODULARIZE
as global object OccViewerModule created by createOccViewerModule().
Global Module setup has been moved to occt-webgl-viewer.js.
Use EMSCRIPTEN_KEEPALIVE attribute istead of listing C functions via EXTRA_EXPORTED_RUNTIME_METHODS.
WasmOcctView now exports static methods as Module functions using EMSCRIPTEN_BINDINGS.
Standard_ASSERT_DBGBREAK_() is now defined using emscripten_debugger().
The visual links between functions are recovered.
The demo is synchronized with a corresponding demo from Qt (qt486-vc10-32\examples\graphicsview\elasticnodes). It may be successfully compiled by any further versions of Qt including 5.10.1
Also, because Open CASCADE (and OCAF in particular) is improved for usage in multi-threading mode, usage of mutexes is added in this sample (for access to the sharing TNaming_UsedShapes attribute, for example).
Added OpenGl_Caps::buffersOpaqueAlpha option allowing to disable writes
into alpha component of color buffer and keep it opaque.
Added OpenGl_Context::SetColorMaskRGBA() method overriding each color component deliberately.
New option is set within WebGL sample.
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.
AIS_SelectionScheme enumeration is defined to set which selection behaviour is used in Select of context
AIS_InteractiveContext is corrected to use single Select method instead of combination of Select/ShiftSelect methods with a selection scheme parameter.
Upgrade: Select() -> SelectDetected/Rectangle/Polygon(AIS_SelectionScheme_Replace), ShiftSelect -> SelectDetected/Rectangle/Polygon(AIS_SelectionScheme_XOR)
Enumeration values have been renamed to use complete prefix Graphic3d_NOM_ -> Graphic3d_NameOfMaterial_
and to match string names (with old values preserved as aliases).
* Menu storage changed from json to XML (because Qt 4 does not support json)
* C++11 for(object : container) construction changed to OCCT iterators / Qt foreach
* enum type::name changed to type_name
* non used class members removed
* Qt connect functions changed to macros version
* warning 4127 disabled for Q_INIT_RESOURCE in VS2010 / Qt 4 case
