[Feature] Support for LZMA vtk files

Feature Request

Given the smaller filesize of vtk encoded with LZMA, and the support in paraview/vtk-python for this compression type, native support in vtk.js could be useful.

Motivation and Detailed Description

See above

Thanks for the report, maybe if you could attach an example file in case someone wants to work on that.

Answer 2 · 2024-03-25T10:21:07.000Z

Certainly! Here's a small example - zipped because github won't accept .vtp uploads.

vtp_LZMA_example.vtp.zip

When reading this in with vtk.js, the error message is quite clear:

Invalid compressor vtkLZMADataCompressor

That will be easier to manage via wasm than plain JS.

@jourdain what do you recommend to use ? i was thinking about using Lzip but this means creating a package and publish it on npm

I was thinking you can get such reader today using itk-wasm. They have a vtp reader which already include LZMA compression support. You can see that by loading that example file within Glance.
