 Each turtle command is interpreted for the creation of the 3d model.  We can imagine that a “turtle” starts at position (0,0,0) in the 3D scene and then follows the instructions given by the nodes in the graph. Reading the graph starts at the top at Node.0 and goes down through the nodes. The first two nodes (Node.0 and RGGRoot) have no effect on the turtle, but a F tells the turtle to draw a cylinder and move to the end of that cylinder. Therefore a second F would tell the turtle to do the same thing again: Each turtle command is interpreted for the creation of the 3d model.  We can imagine that a “turtle” starts at position (0,0,0) in the 3D scene and then follows the instructions given by the nodes in the graph.
