In order to learn programming holograms I'd like to gather some sources in this post.
The linked paper describes already optimised way of rendering holograms. I'd like to find a naive implementation of a hologram i.e. in ShaderToy using interferometric processing of stored inteference patterns like it works in a physical hologram(I guess). I also want this to be a resource to learn how laser holograms work in real life.
To create an introduction project to holographic rendering these steps will be required.
The performance of the solution is irrelevant. Even if takes and hour to generate the data and a minute to render one frame in low resolution that's fine.
Note: The goal is not about creating anything that visually looks like a cool hologram or rendering 3D objects with a volume like with SDFs or volume rendering. It's all about creating a basic physical simulation of viewing a real hologram.
