    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.

waaa with texturing! awesome!
u/tomxor

Thanks :) I just realised I missclassified these. Although it is 2.5D with 3D texturing as Wolfenstien/Doom pioneered, the 2D distance is found using #raymarching rather than casting, which is necessary for size and implicit surfaces.
