trying to know the position and orientations of each limbs during a human or animal locomotion gait... the gait repeats in a loop so thats about 2-5 seconds per cycle, and then multiplied by attitude, condition and given the 3d space perspective of the action, views. it seems like researches are done and simulations are automations exist, so i just need the sort of direct function usable to produce the data that is the xyz orientations and position of each and every limbs? that cant be very complicated i suppose?
use some cycloid and bunch of graph theory?

also it's not a "simulation". so only coordinates and values required...
