    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.

Notice how the objects 'in front' are always drawn 'in front'
u/pavel

This requires a bunch more chars and is only needed when objects have unique colors, which requires more. It seems impossible to do this without compression.
u/pavel

Pretty simple technique, when generating the 3d points instead of directly drawing them, store them in an array, sort it by depth back to front, then draw.
u/keithclark

175. Removed need for reverse() by reversing the projection (far points are painted near and vice-versa): for(c.width|=o=[i=w=960];i--;)o[i]=[C(a=i-t/9)*C(b=i*20),S(a)*C(b),S(b),hsl(${i},69%,50%];for([Z,X,Y,x.fillStyle]of o.sort())x.fillRect(w+w*X/(j=2.1-Z),540+w*Y/j,s=50/j/j,s)

This is amazing. I'm brand-new to coding and very new to Dwitter; how on Earth do all of those symbols and letters code for a picture of the Earth?
u/RomanW

Hi oldspork! The magic happens with the function charCodeAt. This function gets the numeric value of one character at a time. Since these are UTF-16 characters, you can get 16 bits of information in one character.

It is true for this feed view, it doesn't work on different canvas sizes. try full screen.
