How to extract actor edges in VTK.JS

How to extract actor edges in VTK.JS

Are you talking about the representation (surface/wireframe/points)?
You have that example or that one which has Surface with Edges as well.

Thank you very much for your answer, but I am not referring to the representation (surface/wireframe/points), I want to get the edge of the model.

For example, I can use vtkFeatureEdges in vtk, how should I get it in vtk.js ?

vtk.js does not have the filter capable of generating the Feature edges but if those get generated somewhere, then vtk.js can render those.

Thank you, I’ve now understood
