Hello everyone!

Is there a function in vtk.js that would allow making an outline for polydata, but not just a cube in which the figure would be located (as in `outlineFilter`), but something like a wireframe representation, but without triangles inside. If such a method exists, then please share the name, link, example, everything related to it.

If I’m not mistaken, then in regular vtk you can use the `vtkFeatureEdges` method for these purposes, but I did not find it in the vtk.js api.

Thanks in advance!

It does not exist in VTK.js but it should be quite straightforward to port vtkFeatureEdges from VTK C++ to VTK.js.

Do you want to contribute it ?
