    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.

I use 44 longitude lines so the arc angle between adjacent two is 2*pi/44 which is approximated by 1/7 to 4 decimal places.
u/pavel

Using the famous pi ~ 22/7 approximation.

This is based on d/5423 and the amazing bitmap renderer d/5233 by u/RomanW.

Fantastic job! Love the use of the cos(t-i) aka backface culling as alpha value of the fillStyle to sort the splats and skip clearing the whole canvas. That was THE killer optimization to fit in 140 chars.

u/Teijou

Does it JS or another language?

It would be amazing if you could post an expanded, commented version along with your 140 character versions on this site.
u/oldspork

I'm completely new to all coding and just found out about this amazing community; how on Earth do these symbols code for a globe?
u/hg

oldspork These symbols are just what unicode decides his binary data can best be represented as in text. The real magic is the charCodeAt part of their code.

u/oldspork

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.
u/lionleaf

#globe #earth #bitmap #pixelart
u/Purpzie

Is there an easy way to make these kinds of things? (specifically how the data for each pixel is stored)
u/dsamarin

String.fromCharCode.apply(null, new Uint16Array(34).map((r) => Math.random()*0xffff))
