Overview

Currently this is a basic finite-difference time domain (FDTD) simulation, which I initially wrote half a year ago using egui/eframe + wgpu.

I decided to come back to it and switch to bevy instead, tho I might use the egui plugin for UI.

There are other existing fdtd/wave simulations, but I was curious about learning graphics programming/shaders, and running calculations on the gpu instead :p

For initially starting with and understanding FDTD, I read parts of the Understanding the FDTD Method book written by John B. Schneider. The information in it was really helpful for writing the shaders.
