|As described in Chapter 1, IFS and hopalong procedures
can be used to model simple plants (Figure 2 and Figure 3). The fractal fern is a famous object modeled
with IFS and hopalong technique, and there is a good reason for that. There are few other
plants that can also show the same self similarity as the fern. Some simple trees can also
be generated, but it is for example not possible to create leaves or berries on the tree.
The transition probability technique can be used to create leaves and berries. This method
works almost like an IFS, but every object can be transformed into a few different sets of
objects. Each set has a transition probability. The following table will show how it is
This technique is interesting and can create nice
models. This technique will not be explained further as the L-systems, that are described
in the next chapter, are a lot more powerful tool.
