The process of estimating unknown values between known data points, often using mathematical methods. In computing and graphics, it creates smooth transitions between discrete values.
From Latin 'interpolare' meaning 'to refurbish' or 'to alter,' from 'inter-' (between) and 'polare' (to polish). The mathematical sense developed in the 17th century as scientists needed methods to estimate values between observed measurements.
Interpolation is everywhere in our digital world—from the smooth animation in video games to the way your phone's camera creates those silky slow-motion videos by generating frames between the ones actually captured. It's essentially the mathematical art of 'filling in the blanks' with educated guesses!
