Clipping Geometry

I’d like to make a widget like the ImageCroppingWidget but for geometry.

These models are generally vtkjs scenes made up of multiple datasets like the one below:

I was considering a way to use the vtkCutter filter but I’m not sure how to adapt it to cut the scene globally.

I’m thinking something like the following:

const plane = vtkPlane.newInstance()
const cutter = vtkCutter.newInstance()
renderer.getActors().forEach((actor) => {

Do you have any tips as to how to implement this feature?

Thanks in advance! :pray:

I think you can do it on the GPU directly by adding planes to the mapper.

Hey @Sebastien_Jourdain thanks, that sounds like a much better idea. I’ll give it a go and let you know how it goes.

Thanks for the suggestion @Sebastien_Jourdain, it’s working great.


const xyPlane = vtkPlane.newInstance({
  normal: [0, 0, 1],
  origin: [0, 0, 1]

renderer.getActors().forEach((actor) => {
