How to fit a smooth curve to data in 3D?

Hello!
I am currently trying to recreate the path of a fiber in CT scans in MATLAB. I am doing this by finding the midpoint of several line segments of the fiber as it moves through the slices of the data and plotting them. I am trying to fit a relatively smooth line through these points that shouls create a reasonably similar path to the actual fiber.
So far, I have had the most success using the cscvn() function, but the spline is very jagged due to over fitting. Does anyone have any suggestions for how to get a smoother curve? Here is how the spline looks at the moment.
I have tried to use the curve fitting tool app as well, but I am not sure how to use it to create a single line with data in 3 dimensions as opposed to a surface. Any feedback is greatly appreciated. Thank you.
