Hi,  
I am trying to project a scalar array mapped to a 3 dimensional unstructured grid onto a 2d plane. I found [this method](https://stackoverflow.com/questions/45544709/paraview-view-a-2d-projection-of-a-3d-object) but the issue with that is the points on the backface are present on the result. I would like to ignore points that can’t be seen from the plane I am projecting onto. Is there a way to do this in Paraview? I am using 5.5.2.  
Thanks
