3DFX ALLIANCE PROMOTION AT3D DRIVER



Designed to enable a new class of realistic and highly interactive 3D games, Voodoo Graphics offers expanded capabilities above and beyond the basic 3D functionality that will be found in commodity Windows and multimedia accelerators.

3DFX ALLIANCE PROMOTION AT3D DRIVER UPDATE

Major consumer and coin-op OEMs and developers have announced support for the chipset. The support we're receiving from the industry indicates our course of action is the right one.

In the coin-operated entertainment market Data East and Jaleco have announced support and are developing next generation arcade games utilizing Voodoo Graphics. Voodoo Advantage "All of the graphics processors that have been introduced for the PC barely meet the basic requirements for 3D," said Gary Tarolli, vice president and chief scientist, 3Dfx Interactive. When combined with our 3Dfx Alliance ProMotion AT3D capabilities developers can produce really cool, interactive game experiences. To achieve elementary 3D functionality, a graphics chip needs to support perspective correct polygons with point sampled texture mapping, Z- and double-buffering, Gouraud shading capabilities and standard VGA resolution.

In addition, the chipset delivers realistic imagery through sub-pixel correction, alpha blending, and anti-aliasing. Most importantly however, unlike other multimedia accelerators that suffer significant performance degradation when available 3D features are used, 3Dfx Alliance ProMotion AT3D Graphics was designed to simultaneously offer all of these features at real-time frame rates. Voodoo Graphics also supports special effects for even greater game impact.

These include per-pixel effects such as fog, translucency, and transparency, texture compositing, a variety of lighting techniques, texture morphing, animated textures, and reflection mapping. I am of course testing pure AT3D board.

Specifications promised a fine piece of 3D accelerator, press announcement and 3Dfx Alliance ProMotion AT3D would make you think you cannot go wrong. Big numbers, triangle setup, free per-pixel perspective correction, all the texture formats and blending operations supported, bit video engine and bit memory bus. And then you fire up the card, play games and everything is broken.

  • PCI and AGP video chips DOS compatibility
  • 3Dfx Voodoo Rush (Voodoo Graphics + Alliance ProMotion -AT25 or Macronix MX 86251FC)

Many people often say something in early 3D chip is broken, dissing the likes of TridentRage or even Riva But only after you see AT3D in action, you will know how much broken can things be. It is not only the monochrome dynamic lighting or stipple patterns used for all but one transparency 3Dfx Alliance ProMotion AT3D.

Even specular highlights are done via stipple mask. All texture formats from palletized up to are supported. True color textures are full speed and true color buffer is also possible with a small performance penalty.

However, at such depth only palletized textures may be blended "properly". And since AT3D does not use system memory there is with 4 MB little hope for true color rendering at higher resolutions. Could it mean AT3D is tiling 3Dfx Alliance ProMotion AT3D scene?

Frankly, I have no idea, datasheet also mentions Z-buffer compression, but the card does not behave like if it has more memory than others. Gouraud shading is done full speed and geometry looks perspectively ok.

Texturing however, is so warped it turns your accelerated games into chaos barfed all over your display. Perspective correction might have been very well implemented without performance penalty, but somehow at the end all important textures are not adjusted. It reminds me of certain quadrilateral texturing chip trying to render triangles. Such artifacts also prevents closer inspection of Alliances Pseudo Bilinear texture filtering.

Alliance Semiconductor AT3D review

Their ProMotion line of 2D graphics also did 3Dfx Alliance ProMotion AT3D fail, but were not exactly supporting 3D only chipset of 3Dfx. Technical specs says that Alliance chips got a. ProMotion-AT3D/AT24/ pin deltas (PCI bus).

developed by Alliance and 3Dfx, supports glueless interface to the 3Dfx 'VG'.
