Bilinear Filtering Procedure


When drawing a textured shape on the
screen, the texture is not displayed exactly
as it is stored, and most pixels will end up
needing to use a point on the texture that's
'between' texels
Bilinear filtering uses these points to perform
bilinear interpolation between the four texels
nearest to the point that the pixel represents
