Project Overview

Files/Code

• JavaScript code is in main.js. This includes a parser draw() for the grammar. Variables are defined at the top (generations, sequences, and rotation angles).
• Definition of the Fish class is in fish.js.

Flocking

• The movement patterns of the fish are dictated by a flocking algorithm known as Boids Algorithm.

• > rotates the current line clockwise about the x-axis.
• < rotates the current line counter-clockwise about the x-axis.
