These diagrams show that injection strategy and growing strategy. In first one, seed is grown as 3 parts and the tree parts combined as whole thnaks to transition parts also the transition parts have a connection.Therefore all parts aware of each other.While seed parts are injected to field, three different variation is used. Field and seed, field edge and field outside.In second diagram show that ın this model defining spaces from right to left is decreasing in terms of size and complexity.
