Cannot run examples with the current version of Webpack about vtk-js

[jourdain]

Ok thanks, I will try to fix it soon.

The volume mapper example assume that the data you are looking for is active, while the vtkDataConverter does not set any active array. You may want to either programmatically set the array active or edit the json file like here: https://github.com/Kitware/vtk-js/blob/master/Data/volume/headsq.vti/index.json#L32

1. Delete your node_modules directory as well as Documentation/build-tmp.
2. run npm install
3. You should be all set. If not let me know what you did and how you get that error.

Thanks,

Seb

Oups are you talking about npm run example -- NAME?

Yes

Thank you. A semi-related question: So I managed to run an example from an older revision (3239d37). What version of Paraview should the data converter macro work with? I've tried 5.2 and 5.3 and it tells me AttributeError: 'vtkCommonDataModelPython.vtkImageData' object has no attribute 'GetPoints'

Could it be because I'm trying to convert a NetCDF volume?

I'm guessing that you are using the ParaView macro which was meant to be used for geometry extract not volume hence the issue.

To get the volume you should use vtkDataConverter that should be available in your command line environment if you run npm install vtk.js -g or npm link within your local repo of vtk.js.

Then hopefully the help within vtkDataConverter should be enough to get you started. And you will have to do something similar to that example to look at your data.

Is there a specific requirement or file format that vtkDataConverter works with. All my NetCDFs result in NetCDF: Invalid dimension ID or name. I also tried converting them to a .vtk in Paraview, then using vtkDataConverter. That went fine, but when the viewer opens up it crashes with the JS error TypeError: Cannot read property 'getDataType' of null in VolumeMapper.js:23452.

Thanks. That did the trick.
