It's works ok for sampling the pixel corresponding to the output position, because CIFilter gives you some functions that let you do: sample (texture, samplerTransform (texture, destCoord ())) Ugly but fine. Unfortunately, Core Image is probably not the best framework for implementing those techniques since CIFilters are limited in what GPU resources they can leverage (no access to global memory, for example). Filter types are defined by Strings constants, which is very un-Swift-like as it allows for run time errors. size let transform = CGAffineTransform. There is a way to apply a CIFilter to each frame prior to it going to the server.
