surface fitting

Surface fitting is a method used to create a smooth mathematical surface that represents data points in three-dimensional space. Imagine you have a scatter plot of points on a graph, and you want to find a single surface that best matches those points. This technique helps in capturing the overall trend or shape of the data, making it easier to analyze and predict values in different areas. It's commonly used in fields like engineering, science, and computer graphics to model complex surfaces based on measured or observed data.
