BilinearFiltering
From polycount
Bilinear filtering is a method of texture filtering, often used for MIP mapping.
Since the texels are almost always larger or smaller than the screen pixels, it tries to find a MIP-map with texels that are closest in size to the screen pixels. Then it interpolates the four texels that are the nearest to each screen pixel in order to render each new screen pixel.
