👉 In mathematics, "retraces" are a method used in computer science and data analysis to find the closest point on a line or curve to a starting point. It is often used when working with points on a surface, such as a sphere, plane, or cylinder. Here's how it works: 1. Start at a known point on the surface of the object. 2. Calculate the distance between this initial point and the starting point you want to find the closest point on the surface.
