 | The 3d view and the graph structure created by the init function above |
-This function is called very time you reset your model.(either with the rest button by recompiling/saving the code). The basic theory behind it is that the model always rests to the Axiom node and then runs the init function, if one is provided.

 The **moving** part is already covered by the M node for now.
-You can **rotate** the turtle along the three axes x, y and z. We can see an example of the rotation tool on the right with the possible rotations in colors: x=red, y=blue and z=green. In the turtle geometry we can rotate these axes with the commands ''RL(angle)'', ''RU(angle)'' and ''RH(angle)''. RL rotates around the local X-axis (the red circle in the picture), RU around the Y-axis (the blue circle) and RH around the Z-axis. If we imagine to look from the perspective of the turtle, the names make more sense: RL rotates to the __l__left (with negative values to the right), RU rotates __u__p and RH rotates around the __h__head axes.

 Following up on our little example above you could think about rotation the short cylinder 30 degrees up like:
