vtk wasm project without -sMODULARIZE=1 goes well, but with -sMODULARIZE=1 show nothing

Web vtk.wasm

I’m looking into wasm recently. And build the vtk-wasm successfully.
If I build examples in Examples/Emscripten/Cxx/Cone · master · VTK / VTK · GitLab (kitware.com), the cone is shown in my browser, everything goes well.
But if I build examples in Examples/Emscripten/Cxx/ConeMultiBackend · master · VTK / VTK · GitLab (kitware.com) and Examples/Emscripten/Cxx/MultiCone · master · VTK / VTK · GitLab (kitware.com), There is nothing in the broswer except for few buttons used in MultiCone project.
There are no errors in the browser console.
My system is Windows10, vtk version is 9.4.0rc1. Both chrome and edge are used to test.
Any help would be appreciated!

Hi,

I tested again and you’re correct, one of them doesn’t work.

Examples/Emscripten/Cxx/ConeMultiBackend · master · VTK / VTK · GitLab (kitware.com)

This one works for me, just give it a little time as it loads a large number of actors.

Examples/Emscripten/Cxx/MultiCone · master · VTK / VTK · GitLab (kitware.com)

This one has a problem which sets the canvas height to “0”. I’ll debug it.
