model on top issue in WASM

Development

Hello, everyone.
I have successfully compile VTK-9.1.0 to webassembly and it runs in docker fine.
Here is the issue when I need to show model on top of others.
On win11 local C++, it runs OK :

==============================================
vtkNew renderer;

  • vtkNew renderWindow;*

  • renderWindow->SetMultiSamples(0);*

  • renderWindow->AddRenderer(renderer);*

  • vtkNew renderWindowInteractor;*

  • renderWindowInteractor->SetRenderWindow(renderWindow);*

  • vtkNew style;*

  • renderWindowInteractor->SetInteractorStyle(style);*

  • style->SetDefaultRenderer(renderer);*

  • vtkSPtrNew(sphere, vtkSphereSource);*

  • sphere->SetCenter(0, 0, 0);*

  • sphere->SetRadius(1);*

  • sphere->Update();*

  • vtkSPtrNew(sphereMapper, vtkPolyDataMapper);*

  • sphereMapper->SetInputData(sphere->GetOutput());*

  • vtkSPtrNew(sphereActor, vtkActor);*

  • sphereActor->SetMapper(sphereMapper);*

  • sphereActor->GetProperty()->SetColor(1, 0, 0);*

  • const double units0 = -66000;*

  • sphereMapper->SetResolveCoincidentTopologyToPolygonOffset();*

  • sphereMapper->SetRelativeCoincidentTopologyLineOffsetParameters(0, units0);*

  • sphereMapper->SetRelativeCoincidentTopologyPolygonOffsetParameters(0, units0);*

  • sphereMapper->SetRelativeCoincidentTopologyPointOffsetParameter(units0);*

  • // Create pipeline*

  • vtkNew coneSource;*

  • coneSource->SetRadius(2);*

  • coneSource->SetHeight(4);*

  • coneSource->Update();*

  • vtkNew mapper;*

  • mapper->SetInputConnection(coneSource->GetOutputPort());*

  • vtkNew actor;*

  • actor->SetMapper(mapper);*

  • // Add the actors to the scene*

  • renderer->AddActor(sphereActor);*

  • renderer->AddActor(actor);*

  • // Start rendering app*

  • renderer->SetBackground(0.2, 0.3, 0.4);*

  • renderWindow->SetSize(400, 400);*

  • renderWindow->Render();*

  • // Start event loop*

  • renderWindowInteractor->Start();*
    ==========================================

But when I compile them into wasm and run in chrome , it crushs like:

Cone.wasm:0x4c76c Uncaught (in promise) RuntimeError: null function or function signature mismatch
at vtkOpenGLPolyDataMapper::UpdateShaders(vtkOpenGLHelper&, vtkRenderer*, vtkActor*) (Cone.wasm:0x4c76c)

at vtkOpenGLRenderer::UpdateGeometry(vtkFrameBufferObjectBase*) (Cone.wasm:0x657c9)
at vtkOpenGLRenderer::DeviceRender() (Cone.wasm:0x65131)

Does anyone know this ? if I uncomment those “SetResolveCoincidentTopology” lines it can be run without error , but it is not what I want . I need the spere ALWAYS ON TOP of others.

How can I do ?
Thanks in advance and any advices is appreciated !
