Can vtk.js read VTK files with the 'DATASET UNSTRUCTURED_GRID' format?

Feature Request

A way to read the UNSTRUCTURED_GRID type of VTK files

Motivation and Detailed Description

I only found vtkPolyDataReader in the project, which cannot read the UNSTRUCTURED_GRID type of VTK files that I want to use. Is there another way to read these files, or is it not yet supported?

[YuJ1Nan]

I converted the UNSTRUCTURED_GRID type of VTK files to HttpDataSet using pvpython, but I still can't use them with vtkHttpDataSetReader.

Indeed, unstructured grids are not supported in VTK.js.

Thanks, If I want to display UNSTRUCTURED_GRID type of VTK files on the web, what should I do?

That's precisely what this comment talks about: #3014 (comment)

"Okay, but actually I did not see support for this type of file on the website
https://docs.vtk.org/en/latest/supported_data_formats.html. Is it still under development?"

[finetjul]

VTU files are supported by VTK C++. They are not supported by VTK.js.

[YuJ1Nan]

alright, it seems the only way is to use VTK C++
