Updated documentation
Updated samples
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.
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.
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.
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.
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().
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.
Enumeration values have been renamed to use complete prefix Graphic3d_NOM_ -> Graphic3d_NameOfMaterial_
and to match string names (with old values preserved as aliases).
OpenGl_Context now skips loading functions related to mapping buffer,
which are required by OpenGL ES 3.0 specs but not provided by WebGL 2.0.
Message_PrinterSystemLog does not use a broken emscripten_log() anymore, which corrupted UNICODE strings.
WasmOcctView::initWindow() - callbacks now set using EMSCRIPTEN_EVENT_TARGET_WINDOW
instead of 0 used by older Emscripten API.
Mouse callbacks now track canvas element and use
EmscriptenMouseEvent::targetX/targetY instead of ::canvasX/canvasY
as the latter was broken.
Added emscripten_set_main_loop() setup to shut up eglSwapInterval() error message.
Fixed missing \0 at the end of string converted by toUtf8Array().
Message_PrinterOStream::SetConsoleTextColor() skips color tags in case of Emscripten.
Message_PrinterSystemLog now implements log via emscripten_log().
Handled __EMSCRIPTEN__ macros to:
- Workaround atomics (__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 is undefined, but GCC atomics are provided).
- Suppress non-standard header <sys/signal.h> warning.
- Return OSD_LinuxREDHAT.
- Avoid inclusion of XLib headers.
- Skip fontconfig library.
- Enable EGL+GLES path (translated by Emscripten into WebGL).
- Skip eglCreatePbufferSurface() not implemented by Emscripten EGL.
Fixed Graphic3d_Vec4.hxx usage within Quantity_ColorRGBA.hxx.
OpenGl_ShaderManager::defaultGlslVersion() now prefers GLSL 300 es when WebGL 2.0 is available,
as there no any OpenGL ES greater than 3.0 emulation so far.
Shaders_Declarations.glsl - added workaround for GLSL compilation on WebGL 1.0
by defining Light properties accessors as macros instead of functions
('[]' : Index expression must be constant).
OpenGl_FrameBuffer::Init() - added workaround for initialization of GL_DEPTH24_STENCIL8
depth-stencil attachment on WebGL 1.0 + GL_WEBGL_depth_texture extension.
OpenGl_Context::Vec4FromQuantityColor() now considers myIsSRgbActive flag
to handle use case, when Immediate Layer is drawn directly into window buffer,
which is not sRGB-ready.
Added new sample - OCCT WebGL viewer.
