u(t) is called 60 times per second. t: Elapsed time in seconds. S: Shorthand for Math.sin. C: Shorthand for Math.cos. T: Shorthand for Math.tan. R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5) c: A 1920x1080 canvas. x: A 2D context for that canvas.

    I don't really understand maxwell equations, I just wanted to see if I could fit an FDTD into a dweet, and the Poynting vector of the EM field flow looks kinda cool.

    It's essentially a 2D sim of a point oscillator in a reflective box (although technically left and right wrap around), it has absolutely no physical equivalence, all parameters are normalised and tuned for visual preference.
  • u/ximavus
    basically waves bouncing in a box? This visualization is really good though
  • u/cantelope
    oh. well if has no physical equivalence then...
