Hi,

I don't know what "re-order m equal interval points" may be,
but. Here are some data:

data = Table[{Cos[t], Sin[t], t}, {t, 0, 4 Pi, Pi/16.}];

Here is the interpolation:
ip = Interpolation /@ Transpose[data];

and here is a plot of the interpolation

ParametricPlot3D[Evaluate[#[t] & /@ ip], {t, 1, 65}]

And you ca re-tabulate it with

Table[#[t] & /@ ip,{t,1,65,0.00000001}]

Regards
   Jens
