Galaxy generator in THREE.js

In the mathematical field of dynamical systems, an attractor is a set of numerical values toward which a system tends to evolve, for a wide variety of starting conditions of the system. System values that get close enough to the attractor values remain close even if slightly disturbed.

The Lorenz system is a system of ordinary differential equations first studied by Edward Lorenz. It is notable for having chaotic solutions for certain parameter values and initial conditions. In particular, the Lorenz attractor is a set of chaotic solutions of the Lorenz system. In popular media the ‘butterfly effect’ stems from the real-world implications of the Lorenz attractor, i.e. that in any physical system, in the absence of perfect knowledge of the initial conditions (even the minuscule disturbance of the air due to a butterfly flapping its wings), our ability to predict its future course will always fail.

Here is a 3D Lorenz attractor made in THREE.js library:

Galaxy generator in THREE.js

I’ve been experimenting with THREE.js. I am quite new to it and I am really impressed about its performance.

The Lorenz attractor is a dynamical system that exhibits chaotic solutions for certain parameter values and initial conditions.

I’ve been recently thinking a lot about the “butterfly effect”. Where even a minuscule disturbance of an initial parameter (in real-life it could be the air due to a butterfly flapping its wings), our ability to predict the future course will always fail.
