Consider that I have $3$ parametric equations as function of time and describe the motion of a body in space:
$x = f(t)$
$y = g(t)$
$z = h(t)$
These curves are pretty simple and can be modeled within a certain interval by a 2nd order polynomial.
Is it as simple as performing individual fitting on each function or that would break the time relationship between the functions?
Any pointers appreciated.
