Interpolation

Interpolation is a mathematical and computational technique for estimating unknown values between known data points. In software development, it is commonly used in data analysis, graphics rendering, and animation to create smooth transitions or fill in missing data. It involves constructing new data points within the range of a discrete set of known data points.

Also known as: Linear interpolation, Bilinear interpolation, Spline interpolation, Interp, Lerp

Why learn Interpolation?

Developers should learn interpolation when working with numerical data, computer graphics, or simulations that require smooth approximations, such as in data visualization, game development, or scientific computing. It is essential for tasks like image resizing, curve fitting, and creating fluid animations where exact values are not available at all points.
