// An example of simulating a simple rope. For, the construction of rope, catenary algorithm(https://en.wikipedia.org/wiki/Catenary) is used.
// The catenary is a curve that describes the shape of a hanging chain or cable, or the curve described by a freely hanging chain or cable.
// The implementation of catenary algorithm is based on the following js implementation : https://github.com/dulnan/catenary-curve/blob/9cb7e53e2db4bd5c499f5051abde8bfd853d946a/src/main.ts#L254
