 <p>To accomplish the goal of treating each segment as an individual object, I must first decide what this object should be in the first place. What data should it store? What functions should it have? The Koch curve is a series of connected lines, and so I’ll think of each segment as a <em>KochLine</em>. Each <code>KochLine</code> object has a start point (a) and an end point (b). These points are represented as <code>p5.Vector</code> objects, and the line is drawn using the <code>line()</code> function:</p>
