Got a quick inspiration yesterday on an oldskool demoscene effect from the glorious never again reached AMIGAAAA! and how to emulate it as fragment shader. Don’t know how exactly what the effect is called, but its a from of interence pattern effect using circles wich are xor’ed when they overlap. Was really easy to code back in the days when u got a bitplane based graphics hardware like the Amiga. Setup code: GL3_AmigaCircleInterference.java and the corresponding fragment shader: .fs
