I’m using vtk9.3 from pcl1.14.1, the default rendering shape of point is sphere.  
My question is how to render them as square (which always face to user).

Thanks a lot!

Hello @tomdong  
In VTK, the default shape of points is a square. Could you check if PCL is enabling this setting on the actor’s property (`actor->GetProperty()->SetRenderPointsAsSpheres(true)`

Thanks Jaswant!  
I have noticed that this might be caused by calling ‘SetRenderPointsAsSpheres(true)’, however, when I search in PCL code on github, the result is empty 🙂

Then PCL may be using `vtkSphereSource` and glyph filter. Any case, this is a PCL question. Please ask in that community.
