Pendulum Sandbox














The placement functions and the offset function both rely on the variable i, which is the index of a given pendulum along the path. There are always an odd number of pendulums, because there are an even number with a negative index, and an even number with a positive inde, as well as one with 0 index (the middle). Therefore the index of the first pendulum along the path is -0.5(number of pendulums - 1). The offset function determines the t value (along the parameterization of its path) at which a given pendulum will initialize.
