Bilinear Filtering

Bilinear filtering is a function for smoothing out textures when they are mapped onto a larger or smaller area than they truly fit. When the texture is stretched or squished in any manner, it distorts. When this happens, the number of texels per pixel is altered, and pixels frequently end up split between texels.

To determine the colouration of texels made up of several pixels, or those made up of partial pixels on the edges of shapes, bilinear interpolation is performed between the four texels around any particular pixel, or part of pixel.

Bilinear interpolation is itself, simply described as the method of finding a curve fitting (in the case of textures, a smooth blending) in a 2D space, as opposed to a mathematical line.
