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.
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.
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().
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.
