Hi @sankhesh ,
Is there any idea of this? Besides, I found the volume got blured when I place another polyData actor inside the same window, and the polyData actor will also be without anti-aliased as one of my topic mentioned, see https://discourse.vtk.org/t/about-anti-aliased-lines-volume-rendering/10410, is there any way to enable the fxaa to get the lines smooth, and avoid the blur on the volume when doing rotating?
