Interpolation
Interpolation Interpolation |The mathematical method to restore the missing (intermediate) information on the existing set of known values. The simplest type of interpolation method - linear: if there are two values A and B, the range of intermediate values between them is obtained by the formula A * (1 - t) + B * t, where t is a number from 0 to 1. Linearly interpolate can not only be real numbers, but also the vectors. The result of linear interpolation of two colors is a linear gradient.
