hydra sketch log 4

played more with p5 generation, this time looking at more fft bins than i normally do (usually just hit the lowest bin because it’s the most obviously correlative, but this viz shows very clear correlates to all bins)

// Fft ersatz 3d timeseries

// p5 canvas recursion: p5 x hydra @errorbesque
p.remove()
p = new P5();

// setup 
cnv=p.createCanvas(400,400);
oldCnv=p.createGraphics(p.width,p.height);
p.noFill();

// reset
p.background(0);
v0y=p.height/2;
v0y2=p.height/2;

p.draw = () => {
  if ((a.fft[0]<0.4 && p.frameCount%5!=0)) return;
  oldCnv.image(cnv,0,0,p.width,p.height);
  oldCnv.loadPixels();
  p.imageMode(p.CENTER)
  p.angleMode(p.DEGREES)
  p.push()
  p.translate(p.width/2, p.height/2);
  p.image(oldCnv,-12,p.sin(p.frameCount)*2,400,400);
  p.pop()
  a0=a.fft[0]+a.fft[1];
  p.stroke(255,0,255,200);
  di=50
  p.strokeWeight(2)
  if(p.random(-1,1)>0) p.blendMode(p.ADD)
  p.ellipse(p.width/2,p.height/2,
            di*a.fft[1]/2,di*a.fft[0]*2+2);
  p.stroke(255,255,0,200)
  v0y+=p.random(-2,2);
  p.ellipse(p.width/2+10,v0y+p.sin(p.frameCount/10),
            di*a.fft[1],di*a.fft[0]*2+2);
  p.stroke(0,255,255,200)
  v0y2+=p.random(-2,2);
  p.ellipse(p.width/2-10,v0y2+p.sin(p.frameCount/10),
            di*a.fft[1],di*a.fft[0]*2+2);
  p.blendMode(p.BLEND)
}

s0.init({src:p.canvas})
src(s0).out(o0)

src(o0)
  .scrollX(.05)
  .blend(src(o0).pixelate(1000,2)
         .modulate(src(o2).scale(.999))
       ,()=>a.fft[2]/3)
  .hue([0.32].smooth().fast(.1))
  .out(o1)

src(o1)
  .scrollX(-.1)
  .scale(1.15)
  .modulate(src(o2).scale(1.01)
            .pixelate(1000,1000),0.0)
  .out(o2)

render(o2)

a.show()
a.setSmooth(.4)
