**Computer visualization**

Just by varying the parameters \$$\alpha\$$ and \$$\beta\$$, Xia shows that the algorithm produces a variety of natural looking leaves.

In figure 3, when \$$\alpha = 0.68\$$ and \$$\beta = 0.38\$$, a leaf is produced which looks remarkably like an actual maple leaf, which is shown next to the computer generated image.

In figure 4, when \$$\alpha = 0.66\$$ and \$$\beta = 0.7\$$, a leaf is produced which closely matches an actual mulberry leaf.
