How can I smoothly interpolate between 2 position?

How do you interpolate two functions?

The simplest function is to find the closest points and use linear interpolation. e.g. chose two of three closest points and interpolate them. Or you can take a weighted average based on distance. Or you can pick a close point and then find points on the "other side" of the closest point to improve the interpolation.
