    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.

#interactive #quadtree (move your mouse)

u/tomxor

Note the intersection is fuzzy since full circle-AABB takes too much code, instead it's just circle-point + current subdivision width based radius (w*w*6.28), i.e it becomes more accurate as it converges.
u/tomxor

This is why there are a bunch of divisions around it that would not exist with an exact test. Pavel's doesn't do this by cleverly choosing a geometry that only need intersect the top left of each square.

Thanks for all the kind comments :) for those interested: the key is in the parity bit p=i&1 this allowed me to combine two different but similar functions by multiplying parts in an out on each iteration. You should be able to pull the two apart into something more intelligible.

Fantastic job! Love the use of the cos(t-i) aka backface culling as alpha value of the fillStyle to sort the splats and skip clearing the whole canvas. That was THE killer optimization to fit in 140 chars.

oldspork These symbols are just what unicode decides his binary data can best be represented as in text. The real magic is the charCodeAt part of their code.
