Active Window heeft een review gepost van de Matrox Millennium G400 32MB met Dual Head. De review is zeer uitgebreid en bespreekt zowat alle features van de G400. Het lezen waard dus als je deze kaart overweegt. Zie hier een gedeelte over de Environment Mapped Bump Mapping feature:
The Matrox G400 series is the first ever graphics card to introduce hardware support for Microsoft's DirectX - Environment-Mapped Bump Mapping. Environment Mapped Bump Mapping is a DirectX 6 quality feature which will be used to substantially increase the visual realism of 3D scenes. In fact, 3D graphics hardware that supports this feature will be able to render 3D scenes with more realism than was ever before possible on the PC.
Environment Mapped Bump Mapping is essentially a technique that allows a much higher level of detail to be added to a 3D world than could be possible with texture- mapped polygons alone. Fine details such as the pock- marked surface of bricks in a dungeon and scratches on robots and tanks can be added with ease. Special effects such as realistic water surfaces, heat shimmering off hot asphalt on a summer day and air turbulence in flight simulators can also be uniquely accomplished by using Environment Mapped Bump Mapping. This new feature will prove to be as revolutionary as alpha blending in terms of the creative effects that game developers will accomplish when given free rein. With the advent of the Matrox G400 as the first chip to support Environment Mapped Bump Mapping in hardware, game developers are quickly pledging to add support for this feature into cutting-edge games that will ship in 1999.
