vtkPaintWidget changed API slightly. You should no longer need the method updatePaintbrush, as vtkPaintWidget now handles the paintbrush orientation internally.

As floryst was suggesting, would it be sufficient to just update the updatePaintbrush method? To modify anything only if rotateFromDirections exists? I've tested this with the newest vtk.js and have encountered no issues. I could create a PR if that's desired.

I get this error when I try to import this library:

./node_modules/vtk.js/Sources/Filters/General/PaintFilter/PaintFilter.worker.js
ValidationError: Invalid options object. Worker Loader has been initialized using an options object that does not match the API schema.
 - options has an unknown property 'fallback'. These properties are valid:
   object { worker?, publicPath?, filename?, chunkFilename?, inline?, esModule? }
 - options.inline should be one of these:
   "no-fallback" | "fallback"

is this because I'm using vtk.js 15?

vtk.js v15 updates to webpack 5, and with it worker-loader options object changed. Assuming react-vtkjs-viewport is using the vtk dependency file, that shouldn't be happening. Can you print out the whole webpack config?

@manjebrinkhuis +1 for this. Would be appreciated to see this accepted as it's causing us some grief right now. If you don't have time at the moment however I can take it on myself.

@Punzo @floryst or @JamesAPetts just wondering if there was any word on getting the PR approved. If there are any issues just let me know and I'll address them as best as I can.

Hi @tamaynard, sorry I didn't manage to do create the PR for this. Thanks for that!

Additionally to the changes mentioned on this thread, the rendering profile must be included since v18.0.0

Please accept change, this issue open too long
