See this post


which talks about using FXAA in Paraview, but the support is built into VTK


Other options include SSAA an example of which is shown here


Both should be faster than the old AAFrames approach. FXAA will be very
fast, almost free, SSAA will be slower than FXAA and depends on its
settings, as it is a more brute force approach,. But even SSAA should be
faster than the old AA frames approach.
