Hi, I am in the process of writing my book about the specification for a Holodeck. I have chosen with this project to design my own simulation software to simulate the photonic circuitry and that is starting to mature (I am in the debugging and verification phase of design). The book will contain circuitry of a basic photonic core and show it to be working and hopefully how it could drive a volumetric display with touch capability. I like Science and this project is a big one and I am solving problems on a daly basis. I have invested a lot of my time but I think it will be worth it. I am also using my own proof of concept mathematics for derivations of the photonic hardware. It is similar to electronic binary and decimal but in the optical domain.
