    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.

bump mapping remix

u/Joachim

Really nice #lighting
u/@noel

Beautiful. I need to dig into this, to understand how this actually works.
u/rodrigo.siqueira

Wow! Replace X^Y with X|Y to generate Sierpinski triangles. Replace Math.min with Math.max for a more dramatic effect. Remove |0 for improved golfing (a minimal visible effect on top alignment). Replace "t*1.2" with "C(i+t)*6" for the "water effect".
u/jellyedwards

Wow that's amazing!!

My first dwitter. I reduced the drawn area, but it still runs very slow
u/@noel

for(j=-1;j<(w=255);i++)for(y=-1+2*j++/w,i=-1;i<w;i++){k=-1+2*i/w d=Math.sqrt(k*k+y*y) a=Math.atan2(y,k) z=w*C(a)/d+t*w^(w*S(a)/d+t*w) x.fillStyle=R(d,z&w,z&w) x.fillRect(i,j,1,1)}
u/@noel

In java this runs smoothly.
u/@noel

A bit of a disappointment. I am going to try to do this with bigger rectangles now.
u/Xen

nicely done! welcome to the dwitter family
u/KilledByAPixel

fillStyle can be slow when called this often (60,000+ times per frame), you can make a faster/smaller version in grayscale by removing the fillStyle and doing this x.fillRect(i,j,1,(z&w)/w)
u/danny@hille.dk

uncompressed using grayscale and some other golfing tricks ->c.width=w=255;for(m=4e4;m--;x.fillRect(i,j,((C(a=Math.atan2(y,k))*w/d+t*w^S(a)*w/d+t*w)&w)/w,1))i=m%w,j=m/w,d=Math.hypot(k=i/w-.5,y=j/w-.3)

Great first Dweet, by the way :-)

u/danny@hille.dk Thank you. Your solution is really nice. I am playing right now with it.
