    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.

#waves on a #perspectives #sphere -- #d3 #pointcloud

u/f8f82804

this dweet uses a better perspective transform based on Math.hypot -- #hypot
u/f8f82804

The projection still isn't perfect, because I'm rotating the sphere's axis towards the viewer by positioning it below the camera. The resulting distortion is approximately corrected by scaling the Y coordinate with /.9.

Cool, the dark sky makes the water look more realistic tlo

u/tomxor

Wow, you steped up the realism since that sunset a week ago :D this is my fav combo, the stary sky really complements the effect.

Save a char by moving the fillRect call into the loop body to avoid ;
u/yonatan

you're right!
u/keithclark

I love this!
u/yonatan

it's also better to use rect height for the "alpha", avoids the jagged edges on the right. for(i=c.width=99;i--;)for(j=56;j--;)x.fillRect(i,j,1,(S(j*j+i/j-t*7)+C(j**5-i/j*6+t)**3)*j/99)
