Could someone suggest me how to go about getting the wind filter effect in Unity Shader similar to the one available in photoshop and gimp? I did a lot of research and try to read gimp source code, but failed. For Blend mode, I can get answer easily in all sorts of places such as wiki. But when I try to find formulas for filters, I get very little information. Any help would be appreciated.
The Effect just like this:https://docs.gimp.org/2.8/en/plug-in-wind.html
