    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.

fucking awesome!
u/Purpzie

Shaved 10 characters but it's super laggy: for(c.width|=0,i=572;Y=(0|i/13)*27,X=(572-i)%13,i--;x.stroke())x.lineTo(X*160+(X&1?C(2*t+Y/108)*120:0)*(X&2?1:-1),Y-(X&1?108:0))
u/Purpzie

Less laggy version that's 4 characters shorter instead of 10: for(c.width|=0,Y=1188;x.moveTo(0,Y),Y-=27;x.stroke())for(X=0;X++<13;)x.lineTo(X*160+(X&1?C(2*t+Y/108)*120:0)*(X&2?1:-1),Y-(X&1?108:0))

#default on a sphere

u/f8f82804

#d3 #sphere #perspective
u/katkip

how lol
u/pavel

I draw #default one pixel at a time and treat (x,y) of the pixels as angles (a,b) in spherical coordinates. Spherical to 3d cartesian is x=r*sin(a)*sin(b), y=r*cos(a)*sin(b), z=r*cos(b). Projecting 3d to 2d cartesian is x'=x/(2+y/r), y'=z/(2+y/r), and scaling pixel size by 1/(2+y/r)**2 so stuff in the back is smaller.
