Sharky Extreme heeft een artikel gepost waarin ze dieper ingaan op de features van de Matrox G400. Hier een stukje over mip-banding op de G400, TNT2 en Savage4:
G400 employs 'per pixel mip-mapping' which gives rise to horizontal 'mip-banding' as shown below. 'Mip-banding' is a set of artifacts that occur when there is an abrupt transition from one mip-map level to another. Trilinear filtering is a technique to remove 'mip-banding' artifacts introduced by mip-mapping. With trilinear filter switched on, 'mip-banding' is effectively removed.TNT2 uses 'trilinear dithering' which actually introduces dithering artifacts. In addition, the 'mip-band' is sloped, resembling 'per triangle mip-mapping'. Compared to 'per pixel mip-mapping', 'per triangle mip-mapping' requires less computation and is therefore easier to implement. However, the results are not quite as visually appealing as 'per-pixel mip-mapping'.
Savage4 produces a horizontal 'mip-band' that is characteristic of 'per pixel mip-mapping'. Of the three, Savage4's mip-map implementation has the least 'blurring'. Notice the clearly defined tiles at the far end of the narrow path.
