fitting cylinder to 3D points

Hi All,

I have a small task to perform and have no to very little clue where to start.

I have been given a set of data points ( 500), that roughly represent the outside of a cylinder (the cylinder is arbitrarily orientated in 3D space). Iam looking for a way to do two things:

a.) Find the cylinder that best fits this data
b.) Measure the distance from each individual point to the surface of that cylinder, or the distance from each point to the axis of the cylinder.

I want to code this in C++ by reading the data points, but am stuck the whereto find the correct algorithm, or perhaps make sense of the algorithms I have already found.

If anyone has some advice on where to start that would be very muchappreciated.
