Hello,

I’m trying to serialize a vtk scene using:

> <https://github.com/Kitware/vtk-js/blob/master/Utilities/ParaView/export-scene-macro.py>

And it’s, in general, quite buggy. I noticed that there was some work done in VTK on improving this. Specifically:

> <https://github.com/Kitware/VTK/blob/master/Web/Python/vtkmodules/web/render_window_serializer.py>

Is there any documentation on the use of this new serializer?

Those are quite different. The macro was a proof of concept showing how to serialize a scene and render it using an application like [this](https://kitware.github.io/vtk-js/examples/SceneExplorer.html).

The second approach is used to dynamically synchronize the render window over the network. It is used in [ParaView Visualizer](https://kitware.github.io/visualizer/).

Also the macro was replaced by a C++ implementation in [VTK](https://github.com/Kitware/VTK/blob/master/Web/Python/vtkmodules/web/vtkjs_helper.py) where a Python helper is here to zip the directory and also bundle the Glance viewer along with the data.

The new implementation is available in ParaView/master or 5.7 as a web export.

Thanks for your helpful response!

I look forward to using the latest C++ implementation in the next release of VTK.
