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.
