    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.

Voxel Rendering

u/SockTaters

The math in R() ensures the farthest voxels from the viewer are drawn first regardless of rotation. If a 2**X by 2**X grid is labeled the obvious way (with the numbers 0 to 2**(2*X)-1 left-to-right, top-to-bottom) and n is the index of a given corner, then i^n maps i to an ordering that starts at n's corner and ends at the opposite corner. Rectangles of 2**X by 2**Y might also work. The math in R() is somewhat obfuscated for golfing purposes.
u/SockTaters

n=[0,3,12,15][0];for(i=0;i<16;)console.log(i++^n)// try these 4 corner indices

Click and drag across the top of the canvas to draw the palette. Once the palette is drawn, click any color to select it.

interestingly, the canvas drawable height may be taller than expected, which you will notice if you save the image ;)
