CHAPTER 14 ■ RECURSION

■ Note The code for drawTriangle could be made simpler by starting at the outermost layer and counting

backwards. However, I wanted to have a maxLevel value to make setting the depth as easy as possible. I also

used Point2D rather than Point to obtain a greater level of accuracy (and thus prevent small mismatches in the

positions of the triangles within the window).

Finally, here's the result of my SierpinskiTriangle program:
