Lesson 4 of 10 · Strange attractors on the GPU

The swarm

From one point to thousands, under the same rules.

One point tells a story. Thousands reveal the entire form. We release 6,000 points; each starts somewhere different and obeys the same rules.

They fall onto the same structure from every direction. The attractor appears.

NHow many particles you release. More particles make the form denser. We will raise it to 130,000.
TryMove Stretch and Inflate: they edit d and a in the equation. The form reconfigures instantly.

The code

vec3 attractor(vec3 p){
  // Aizawa · mueve los números y mira
  float a=0.95, b=0.70, c=0.60, d=3.50, e=0.25, f=0.10;
  float dx = (p.z - b)*p.x - d*p.y;
  float dy = d*p.x + (p.z - b)*p.y;
  float dz = c + a*p.z - p.z*p.z*p.z/3.0
           - (p.x*p.x + p.y*p.y)*(1.0 + e*p.z) + f*p.z*p.x*p.x*p.x;
  return vec3(dx, dy, dz);
}
