    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.

would it be possible to zoom the canvas out as the pattern expands?
u/katkip

not really, save the points into array

Ray Marching SDF Sphere+Bumps

u/tomxor

Specifically, sphere tracing, with axis aligned field, i.e no perspective, marching along Z only. The sphere is not rotating, the simple displacement map is just being pushed through it's x.

orthogonal raymarching... nice idea

You said it more succinctly :)
