Diffuse Limited Aggregation Simulator

This app simulates 2D diffusion limited aggregation on open or closed topologies using random walks to generate Brownian trees.

Diffusion limited aggregation occurs when randomly moving particles cluster together into aggregates forming (in simulations) 2D fractals.

Technologies used

Node, Express, JavaScript, EJS/HTML, and CSS.

To run

clone the repository and navigate to it. Edit .env if you're inclined to change the port from 3000, e.g. PORT=5000 or any other port you wish to use. If desired, you can also edit the row and col in controllers/home.js to change the simulation granularity, save any changes and run:

npm install
npm start

Navigate to http://localhost:3000 replace the port with the one you chose.

Improvements

Improved efficiency to reduce rendering load, allowing for larger simulations with more particles.

Generalized functions to enable users to setup and interact with simulations.

Improved width and height setting to allow dynamic resizing of pixels based on simulator size.
