Repeat or interpolate an uneven path

Question

Say I have a path consisting of three-dimensional points, where the distance between successive points is not constant.

How to redo it so that the distance between successive points becomes constant?

I tried to look into interp1, but I do not know the starting points of the request for the hypothetically parameterized curve x (t), y (t), z (t).

Example path:
