    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.

Oh no the challenge has been set! i'd imagine it sounds a bit like wavetable synthesis, even though it's not.
u/KilledByAPixel

it sounds like tone morphing between a sine and square wave.

#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.
u/katkip

Nice!

#PCB #trace #bumpmap

u/tomxor

Getting on the bump train with a different method. This one displaces X and Y in proportion to distance from light source, which creates pixel gaps on one side (specular highlights), and overlapping pixels on the opposite (becoming shadows).
