    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.

conga bump #default #dance (the first version was missing something)

u/pavel

shouldnt they get thinner in the back, not wider?
u/pavel

Here is a rough starting point using real orthographic projection for(c.width|=i=9;i--;x.fillRect(960+2e3*S(a)/z-s/2,540+2e3*y/z-s*2,s,4*s))y=S(i+t*39)/99,z=3+C(a=i/8+t),s=99/z
u/BriSeven

they get thinner at the edges and shorter in the back. the fatter appearance is an optical illusion from the perspective
u/BriSeven

i imagine them as thin sheets of material rather than as cylinders.
u/BriSeven

it would probably look better if the front and back had the same aspect ratio but there’s only room for so many sine/cosine functions

An unfruitful experiment in compressed canvas method calls.

Show more comments…
u/pavel

How about something like i=0;for(m in x)u[i++]=m;x[u[34]](512,512,512,512) Shortens every call to six chars at the cost of 24... Maybe shorter if you call globalCompositeOperation and some shadow methods too hah.
u/pavel

Or how about this f=(n,a)=>{for(m in x)--n||x[m](...a)};f(35,[512,512,512,512]) 37 chars to reduce every name to one or two chars.
u/pavel

Three or four chars**
u/pavel

aw, actually none of these work for stuff like globalCompositeOperation as they are not methods.
u/BriSeven

Good one, I was also thinking about the possibilities of something like an.. uhh, a tiny bytecode interpreter? take a string and convert it to function calls and parameters somehow.
u/pavel

i=t&&u;for(m in x)x[i++]=x[m];x[34](512,512,512,512) costs 29 to make calls 3 each.
u/pavel

Lastly, can do something niche like for(m in x)x[m[4]]=x[m];x.R(512,512,512,512) that costs 23 and shortens to 1 char but a subset of all calls.
u/BriSeven

wow are these established techniques or did you just think of those now?
u/pavel

i made them up just now but they are simple remixes
u/yonatan

for(p in x)this[p[0]+p[6]]=p sets up shortcuts on this so you can do x[gC] instead of x.globalCompositeOperation (from d/10842)
