    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.

Hacker typer, but the cursor resets when a key is pressed. Had to sacrifice the reset at the end...

Remix #rainbow #flag with improved palette and #phong #shading with better shadows- - #pride #pbr

u/f8f82804

Correct shadows are implemented with the 0<α factor. To golf this in, I had to drop the diffuse reflection term and reuse constants. Palette improvements just took tweaking without extra characters.
u/f8f82804

Loop restructuring also give a very slight FPS improvement.

endless urbanscape

u/zanella

Replace v with v%1080 in the fillRect call and it will redraw itself over and over again. ;)
u/DataMeta

Not sure what you mean - it already re-draws. Hence the 'endless' :P
u/zanella

Weird, the first time I saw this it didn't redraw itself - it seemed to stop once the scanline hit the bottom of the canvas. Didn't notice that it already had a %1080. So yeah, my comment is pretty useless. :)

I love it, but I really wanted to do it without compression. I even tried using fillText('●'). See my remix for the closest I could get.

u/fujimotos

x is CanvasRenderingContext2D (something you can get by calling canvas.getContext()). It is one of the shorthand variables predefined in dwitter.
