    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.

Beenary Clock

u/tomxor

4 levels of geek - bees, beenary representation, beenary segmentation of 1 rotation of the hive into 2**16 (the lowest bee counts ~1.32s increments aka "bees"), based on the apiformes epoch (no leap bees, no queen zones, no hivelight saving bees, yes... it will gradually drift out of sync with the hive's rotation, currently by 20.48 bees or 27 "seconds" in old humanoid time. When the difference approaches 2**15 bees it is speculated honeygeddon will occur, or perhaps more realistically an aristocratic upheaval and abolishment of apiformes epoch based bee keeping).

Ray Marching SDF Smoke #improved resolution

Exchanged marching depth for resolution... makes it a bit less 3D but a but more smokey i think.

Ray Marching SDF Smoke

u/tomxor

Runs significantly faster in FireFox for some reason.
u/tomxor

Part of the smokeyness is obtained by exploiting artifacts in the ray marching algorithm itself, by only marching a constant and very short depth (4 steps) smooth aberations appear around the true volume (representative of the sphere tracing)

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 :)
