Generates wind turbines at each given point according to the spinner height and rotor
diameter in meters.
The generated wind turbines are based on the provided glTF model, which should follow the
following scheme. All parts of the turbine model must be contained within two nodes.
One node, named rotor, contains all rotor parts. The origin of this node should be
located where the rotor connects to the nacelle and one of the rotor blades should point
straight up.
The other node, named tower, contains all other parts (tower, nacelle).
The model is assumed to be in real-world scale, where one unit corresponds to one meter.
The output parameter height is the total height of the generated wind turbine.
