Hello I have a question about the using of vtk in the binding of a c++ class that use some vtkObject pointer, in fact I can compile my bind with emscripten and when I run the .js file in output I can execute my test code.

Did I need to bind the vtk classes, I think not because I compile VTK with emscripten. Is anybody have some similar issues and/or a begining of a solution ?
