    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.

Just testing some sine wave patterns

Show more comments…
u/danny@hille.dk

Anybody remember the original PS3 dash wave patterns? Any ideas on how to replicate?
u/Xen

possibly bezierCurveTo() with .2 alpha?
u/danny@hille.dk

Definitely some alpha involvement, but i think you need a plane and add some waves to that, and then rotate the plane and add some waves to the planes edge. I tried to replicate in 2d using only sin function, but it lookes like... a bunch of sinus curves :-) http://glslsandbox.com/e#69430.0
u/danny@hille.dk

I found a video of the dash waves... Im not even remotely close :-) https://www.youtube.com/watch?v=UMzKdD_6oUE&…

My mix: for(c.width|=Y=9;Y>0;Y-=.2)for(m=X=400;X-=2;)x.fillRect(X*5,C(t+X/130)*S(t*2+X/255)*m+m+Y**2+Y*X/77*S(X/99+t*2+C(X/25-Y)/5)*9+99,10,.5)
