Hi,

I have a C++ example of depth peeling where they used [vtkProbeFilter](https://discourse.vtk.org/t/how-to-set-defualt-value-for-vtkprobefilter/8116) to apply peeling on a VTK skin head surface using the VTI volume values, and a slider to give the value of peeling, to finally get the VTK brain surface, I want to implement this in VTK.js, to be able to reduce the VTK head surface using x,y and z sizes (From my VTI volume) and get the VTK brain surface,

I noticed that vtkProbeFilter is not supported, is there another way to apply this idea

Thank you
