This article explores creating halftone effects using GLSL shaders, starting from rendering simple dot patterns on a grid to advanced techniques like CMYK color separation, Moiré interference, and animated displacements. It discusses the optical illusion behind halftones and details shader implementations including distance fields and pixelization to align dots with underlying images, enhancing artistic and textured digital outputs.
