How it works

Glass Star is a real [[stitchable]] Metal shader, not a video or an image. It runs as a SwiftUI .layerEffect, so it reads and reshapes the whole layer of the view it is attached to. You shape it with sliders in a live preview, then export the .metal file and the SwiftUI code that uses it, or the React Native and Web version. No MSL to write.
