Recursion

Now, the trick is this: each placement repeats this entire process. That means

• huge features place large ones,
• large features place medium ones,
• medium features place small ones,
• small features may place other small ones (subject to small_scatters_small_chance)

The logic for each placement starts from here (i.e. we ignore steps 1 and 2 of the “first placement” because we already know the sizes and we know we’ve started in the correct biome).

This recursive process leads to interesting clusters of features (like the clusters seen in fig. 1), where the intersection of multiple texture stamps can create very complex geological shapes.
