Works buttery smooth for me. What are the practical applications for this though? I imagine if you try to use this too much it would significantly slow a game down.
There is one nuance. This effect apply only on pixels. Not Texels. So — no matter how much polygons. Matter how big screen resolution for all this.
Theory is - when you know everything but nothing works.
Practice is - when all works, but you don't know why.
We combine theory and practice - nothing works and nobody knows why
