bicubic-sample

Conveniently interpolate arbitrary 2D grids using bicubic interpolation.

Usage

sample = require('bicubic-sample')(getter)

Returns a sample function that you can pass points to.

getter is a function which takes an x and y argument and should return the value at that point in space. These values will both always be integers.

sample(x, y)

You can now pass any pair of x/y values to sample and get an interpolated result.

sample(0,0) is the equivalent of getter(0,0), however if you were to call sample(0.5,0.5) the result would be a smooth and curvy interpolation between the surrounding points.
