based on the entire motion of a single cycle or loop or sequence,
how can one simply, but correctly
determine location of one object in one frame to the next, in example, the pelvis and the knee here,
and then to the next,
in order to achieve exact naturality and believability of the motion
based on the subject be it bipedal or quadruped, and the perspective,
be it angular, fish eye or side
like image here
perhaps, in precision mathemathically or physically
since "eyeballing" it, does not just decide enough value in itself
I don't move like everybody else. I move differently so no one mistakes me for someone else.

Simple enough. Just put a Microdot GPS tracking device, at the locations you want to monitor.
