Multilinear Interpolation
There is a neat visualization of linear interpolation that generalizes to higher-dimensional spaces, including bilinear (2D) interpolation, trilinear (3D) interpolation and general multilinear interpolation. At all levels it is much easier to remember the visualization than the formulas directly. Let’s start with the simplest case… Linear Interpolation Linear interpolation is a weighted average of 2 […]
