 Looking at our two organs, we can define our very first rule: //a bud becomes a shoot//, or more precisely //every bud becomes a shoot//.  Looking at our two organs, we can define our very first rule: //a bud becomes a shoot//, or more precisely //every bud becomes a shoot//.

-Now in the last real step of this tutorial we want to look at the diameters of our little tree. +Now, in the last real step of this tutorial, we want to look at the diameters of our little tree. 
-In the F class that our shoot extends the diameter can be given as an second parameter: ''F(length,diameter)''. So we can just do the same thing as we did with the length and have a parameter d in our shoot hat is then forwarded to the F:+In the F class that our shoot extends, the diameter can be given as a second parameter: ''F(length,diameter)''. So we can just do the same as we did with the length and have a parameter d in our shoot that will be passed to the F:
 <code java> <code java>
  module Shoot(float l,float d) extends F(l,d);  module Shoot(float l,float d) extends F(l,d);
 </code> </code>
  
-Now for defining this value in our rules we will use a very simple estimation. Lets assume that the ratio between the length of a shoot and its diameter is 10:1. This means in all our rules we can just change the Shoots to ''Shoot(x,x/10)''.+To define this value in our rules, we will use a very simple estimation. Let us assume that the ratio between the length of a shoot and its diameter is 10:1.

-Even so this gives our tree already a nicer first shape, there is another thing we want to do with the diameter: secondary thickness growth.  Therefore we add a new rule that states that every Shoot will be replaced by a new Shoot of the same length but a slightly larger diameter. +Even though this gives our tree a nicer initial shape, there is something else we want to do with the diameter: secondary thickness growth.  So we add a new rule which says that each shoot will be replaced by a new shoot of the same length but with a slightly larger diameter.
